PORTABLE LIGHTWEIGHT OXYGEN CONCENTRATOR
This project was shortlisted for Loughborough Enterprise design award and was also featured on ‘Favourite disability designs from 2017’s graduates’ on Crack it design website by Demand.
RESEARCH . In the UK, approximately 10,000 people are newly diagnosed with a lung disease every week. Lung diseases could happen to anyone at any age. People with respiratory diseases carry around oxygen tanks with them. However, oxygen tanks are heavy, need constants reﬁlling and maintenance hence why the oxygen concentrator is a better alternative. Patients with respiratory diseases are embarrassed to carry oxygen tanks or concentrator around. They feel socially awkward to carry around the oxygen tanks, and it also limits their daily active activities.
USER INSIGHTS . Oxygen therapy is the medical solution for patients with lung diseases. To fully understand their pain points and the market really well, a combination of primary and secondary researches are needed to identify design gaps.
Quiet machine noises
Short battery lives
Long lasting battery
This portable oxygen concentrator concept design weighs just around 1.5 kg, containing long-lasting battery life, simple user interface and functionality focused. The design also features an integrated oximeter and heart rate sensor with Bluetooth connection to smart devices to help reassure and track the patient’s use of oxygen.
Various concept are explored to identify the potential design for functional and aesthetics purposes. The design is explored in many various aspects. Not only just forms and shape that could potentially be made more appealing than existing products in the market, but also explore possible functionalities that can be achieved with the speciďŹ c shapes.
PROTOTYPES . USER TESTING . ITERATIONS .
“ Why prototype something if it will just be sitting there and do nothing? ” Externally The aim of prototyping is to use it for testing your concept at diﬀerent levels of ﬁdelity. The prototyping stages range from blue foam ( testing out the initial form of the design) up to a 3D printed model (that was used to evaluate the product feasibilities with the users). Internally Not only the externality of the machine is critical to analyse, but also the internals. The primary purpose of this design is to have a long-lasting battery and a technology that could reduce the size of the oxygen concentrator and weigh a lot less. Therefore, it was crucial to test out the internal circuit, and the main functionality of the oxygen concentrator was to be understood. The internal was prototyped mainly by software coding using Arduino and hardware building. The components are chosen specially for patients that require a low LPM (litre per minute) continuous oxygen ﬂow whom just started having respiratory diseases. The design also included an oximeter so that the user can monitor their heart rate and oxygen level by using a new oximeter technology that can be found in smartphones and health trackers. This sensor has not been intergrated anywhere medically for respiratory equipments. Final 3D printed parts after various design iterations
ASKING THE PROFESSIONALS .
Great Insights usually comes from people who have the needs to use the product regularly.
User insights are gained from this stage of design development. Various participants are chosen to test out and gain their qualitative feedback from the design. This then is later use to iterate the design and improve it accordingly.
65 years old, London Suﬀer from bronchitis and asthma. The participant needs to always carry around with her the asthma inhaler and was on oxygen therapy for a short while. She lives an active lifestyle and does not like to stop and be at home. She likes the simple, interaction and feel like it is highly useful, applicable with the diseasesince to carry out any sort of testing, mainly the participants needs to go to the hospital .
LISA . 71 years old, Nottingham Suﬀer from COPD. The user felt like the machine is compact, small and highly portable! The participant did not feel like it disturb her daily routine. It is a lot easier to manage comparing to the existing one the participant has been using. She suggested that a cut out from the battery section should also be considered since it would be a good indicator of where to pull the battery out from.
SARAH . 25 years old, London Respiratory nurse at St George’s hospital. A lot of knowledge was gained from the nurse about how various patients reacts, get diagnosed and how oxygen is prescribed out. One feature that stood out was the Bluetooth tracking feature. As a nurse, it is hard to get an accurate tracking and reliable answers from the patients about how much oxygen they have been using.
These are the ﬁnal prototypes. 3D printed model for aesthetics and the other one is for functionality internally.

PROMOTIONAL PEN HOLDER WIDGET
THE UNIQUENESS .
This project is a truly unique project since it mainly emphasises on the manufacturing side of the product. The aim of this project is to create promotional give away widgets for a speciﬁc brand as a marketing product through an injection moulding process. The widget must be low in monetary value but still appeal to customers. In a team of 6, we all came up with an idea. The Copic idea was chosen to be taken forward for manufacturing due to the feasibility and the bold identity of the brand. Copic is a brand that is close to all designers’ hearts hence it being the ﬁnal decision.
DESIGN PURPOSES . A common issue that artists and designers usually face is the fact that the markers clutter the desk. This Copic marker holder would be a handy promotional widget that is designed to reduce the clutter on the desk by only keeping their main markers in hand. This enhances the user’s workﬂow and organisation of the working space.

The simple design acts as a visual standpoint resembling a marker from a side view.

MANUFACTURING PROCESS .
3D PRINT A quick prototype is printed so the overall form can be analysed before committing to manufacturing the mould.
LATHE Series of pins and bars are made by turning mild steel rods to a particular geometry for holding the inserts and blocks in place for the injection.
FINISHING All the parts were polished up by hands with emery cloth and wet & dry paper for better mould assembly and surface quality.
PROBLEMS & SOLUTIONS .
FOAM BLOCK A prototype foam mould block was made to test if the tool paths were correct. Mistakes were resolved, and engineer drawings were updated.
MILLING The main inserts were made manually on the milling machine. Perfect tolerancing had to be achieved at this process for mould assembly.
ASSEMBLY All the inserts, pins and mould blocks were tightly assembled and locked together, ready for the ﬁnal injection moulding process.
CNC MILLED After all the CNC tool parts were perfected, aluminium mould blocks were CNC milled along with three other inserts.
SURFACE GRIND The grinding machine was used to achieve the precise tolerance ﬁnishes especially when it could not be achieved by the milling machine.
INJECTION Finally, HDPE plastic was injected into the mould to create the widget. Gate size was altered to prevent short shots and allow even ﬁlling.
Tolerancing was one of the main problems that we faced when it came to manufacturing the inserts. Human and machine errors build up through the manufacturing of inserts creating chain tolerance, building up, and causing the assembly to become rather troublesome. The main insert was created several times because the dimension of the piece was slightly too small causing it to not ﬁt properly with other inserts. This would cause ﬂashing when the plastic is injected. Teamwork was the greatest asset in this project. We helped each other by delegating diﬀerent tasks to suit speciﬁc skillset and maximising the eﬃciency of our team. We helped each other ﬁgure out the problem and try out various solutions. For example for the main insert tolerance, we ended up milling down and leaving some depth for it to get grind down for highest precision.

. SUB INSERT 2
Place another sub insert upside down to create a small gap between the parts.
. 3 X 12MM PINS
Push the pins into the main insert but also making sure that the 4 mm holes aligned.
. 2 X LOCATOR PINS
Finally, the pins are pushed into the holes to secure the overall assembly of the mould.
The mould tool is designed in CAD through Creo. Tooling path was also developed before it gets manufactured. Pressure and plastic analysis were also done to come up with the best design of sprue gates and injection position. Plastic advisor also illustrates the possible warping and the in the consistency of the plastic that could occur with diﬀerent wall thickness. A calculation also determined that for each widget, 16.03g of HDPE plastic is needed to create one widget which ﬁts well into the initial set budget.

THE SAFER THAI TAXI COMMUNITY MOBILE APPLICATION
PEOPLE . Startup Weekend attendee backgrounds are roughly 50% technical (developers, coders, designers) and 50% business (marketing, ﬁnance, law). It was a great experience to meet new people from so many diﬀerent backgrounds and allowing my self to use my creative knowledge to help each other to bring to life an idea in an intensive environment.
SKILLS . My team consisted of 5 people; we all have our own skill sets that can contribute values and knowledge to the team. These skills are great assets for the team to create and start up a business idea.
Startup Weekend was a 54-hour event designed to provide superior experiential education for technical and non-technical entrepreneurs. Beginning with Friday night pitches and continuing through brainstorming, business plan development, and basic prototype creation, Startup Weekends culminate in Sunday night demos and presentations. The weekend was centred around action, innovation, and education.
As a product design graduate, I was the one who leads the team regarding the design aspects. I was able to use the design thinking concept among the group to make critical decisions.
In the team, there were 2 developers in the team. They came from a very technical background full of logical mindsets. They came up with eﬃcient and logical ideas to various problems.
A team member runs a leading security family business in Thailand. She was able to provide various ideas on how to manage and run the business.
The last team member came from a strong ﬁnancial background. He provided the team with great analytical mindset, many ﬁnancial and funding advice for the ideas.
The event was a Women startup weekend, and so our ﬁnal idea was inspired by women.
In Thailand, there are 3,000 reports on taxi cases in a month about reckless drivers, sexual harassment and belongings lost. According to NIDA poll, 75% of taxi users faced problems at least once. Missbehaved drivers information are not shared with the public, and the same problem keeps recycling in the society. Due to this ongoing problem, existing solutions like Uber and Grab charges high surge prices so that people can feel ‘safer’. They also have insuﬃcient number of cars, high waiting time and it is ILLEGAL in Thailand.
PRIMARY RESEARCH .
As a group, we went out in Bangkok surveying the society about the problem and their views on Thai taxi. A lot of people even the locals feel unease and paranoid when using the taxi service.
“I never take a taxi at night because it feels very insecure and unsafe.”- Suda, 22 “I always pretended like I’m speaking to someone on the phone so the driver doesn’t talk to me.”- Manee, 28
To guide the functional and visual development of the app, a persona was created whos situation is more extreme. Basing it on primary and secondary researches the concept is tailored to work for users at the end of the spectrum could later generate ideas which are useful for everyone.
Accountant at Bangkok bank, 27 years old Rosarin usually takes public transport, the BTS sky train to work every day. Often if she is working late shifts at night or go out after work with her friends, she would take Taxis to get there since she does not have a car. She usually ﬁnds that Uber is a lot more expensive due to the high charges that come with the ridiculous traﬃc jam in Bangkok. Therefore she prefers to use the usual local taxi to get to places. When she is in the car, usually she will always make sure that she takes a picture of the license plate in case anything happens and she always tries to avoid making conversations with the driver. TASK GOALS
Rosarin usually wants to get from a restaurant back home after late dinner or after she has been out drinking with her friends. She wants something or someone that she can rely on while she is travelling in the taxi especially at night. She just wants to be safe from all the possible scenarios that could happen to her.
She wants to feel safe while travelling in the taxi and want to feel conﬁdent using it, especially at night. She wants to use the taxi service more often when she feels like it is more reliable and safer. She wants to trust the local taxi community, but from all the cases she heard of, she still does not entirely have trusts in it.
HIGH FIDELITY WIREFRAMES .
Welcome screen when opening the app after the user already login and registered.
Search ﬁltering page, type in the license plate number to ﬁlter down the number of taxis in the system.
Select the right license plate for the taxi that the user is about to get onto to check the review.
The review for the taxi will come up and see the other passenger’s past experiences and reviews.
When the user is on the journey, the user can send live locations to their chosen friends and family.
An automatically generated text will be sent to the selected person to conﬁrm the user’s location.
SOS button is at the top of every page in case if anything happens. Help tips are also given, and there is also an option to search and call the nearest police station to the user.
The user can end the trip on the main menu page. They can also access other main features of the app.
After the ride, the user is to provide feedback on that taxi ride experience and comment on anything in particular.
The user can select an automatic location and information sharing to the chosen nominated contact as soon as the user is in the taxi.

FINAL OUTCOME .
Anzen is a simple mobile application that is an honest based reviewing system that allows the user to distinguished good and bad taxi even before the journey starts. Anzen also includes safety features for users that are in the taxi. Users would incline to feel more secure since they are always connected to their friends and family, and they can quickly ring up the police station nearby if anything ever happens. Real customers based review system usually seems to be more reliable and relatable. Consumers’ word of mouth is seemed to be more persuasive than companies or celebrities if started a campaign or advertisements are started for it. Anzen revenue stream will come from Thailand Road Safety Fund (Department of Land Transportation), government subsidies, in-app advertisement and donations from the community. Anzen’s ultimate aim is not to generate high proﬁt and revenue but to raise reliability and use of Thailand’s local taxi services. This is so that people can change their perception of Thai’s taxi and start to trust the service more. In the long run, it will hope to generate more income for taxi drivers, and people are less incline to spend their money on services like Uber or Grab taxi.
Anzen was awarded for judges’ favourite concept.

SECONDARY RESEARCH . Gained statistics, scope of the brief, key areas and researches
Many adults in the UK spend more than 7 hours a day sitting or lying. (Choices, 2016)
Studies have linked excessive sitting with being overweight and obese, type 2 diabetes, some types of cancer, and early death.
Oﬃce workers are most likely to get hungry again and snack more, with 35% reaching for treats, compared to 14% of non-oﬃce workers.
51% of 1947 women confessed to eating between 650 and 750 calories worth of snacks each day with 87% regularly squirrelling treats away at their desk.

THE MAGICAL PLACEMENT YEAR
PLACEMENT YEAR AT DISNEY . “It's kind of fun to do the impossible”- Walt Disney I was lucky enough to experience how to make the impossible, possible. During my placement year in London as a product development intern at the Walt Disney company, I learnt how the world-leading company operates using multiple business strategies driven by numerous amount of creativity. In-depth, I explored the world of licensing and worked with diﬀerent markets across Europe, Middle East and Africa where the needs among the various cultures and restrictions within each market are demonstrated, especially the emerging markets. I worked mainly for 3 teams during my year at Disney.
I developed various product concept that is plausible in each emerging market. With emerging market like Africa, the product that will be developed must be low budget. With that in mind, the product still needs to keep the Disney brand standard. I had to ﬁgure out the right balance between the two and create something unique for the licensee.
Sales (Strikeforce) team
I got the chance to manage a product brainstorming event within the company and use my inner creativity to create product mock-ups with various Disney, Lucas and Marvel characters to inspire people internally and externally, like licensees, to see the potential products to be set up in their local markets. I also initiated the ﬁrst sales team newspaper to be distributed around so that people can have more knowledge of Disney’s new properties.
Publishing The UK is a country where books and novelty are still hugely available to everyone. Within my role, I had to explore the streets of London and go to various trade fairs to look at the current books publishing and toys trends. I then use those trends and update other publishers in the emerging markets and inspire them to use the Disney properties that they have on hand to create new products in their local market. This was such an inspiring year. I was exposed to so many inspiring people and learn how the most magical company takes the creativity and bring it to real life.
DR. STRANGE .
This was a particular project that stood out. This was the concept development artwork I did Doctor Strange the movie. The brief was to design apparels and accessories for young adults. My work was later, not only approved by Disney but also approved by Marvel headquarters in New York. The concepts were used to inspire many well-known clothing brands globally like H&M, Primark, etc., so Disney can potentially create a clothing line through with them to promote the movie and generate more income through licensing.
“The greatest gift we an recieve is to have the chance, just once in our lives to make a diﬀerence.”- Stephen Strange
BACK TO SCHOOL
This concept was based on 'back to school' theme for young kids. The movie came out in the summer holiday when all the small kids would later go back to school. Therefore it was an excellent opportunity to create and sell something to do with schooling, for example, backpacks, lunch boxes, etc.
The Jungle book concept was aimed at older middle school kids. The artwork for this movie is a lot more sophisticated, and as it is such a Disney classic, this was the perfect opportunity to create something with lots of jungle theme patterns and use the main characters to make the products iconic to consumers.
KELLOGS X DISNEY .
THE PERCEPTION .
When it comes to FMCG and food, there is a perception that when Disney is branded onto a food package, this food is unhealthy. This was mainly to do with the previous packaging design that uses bold, wacky colours with big bold characters on the boxes. Although these designs attract children, it does not persuade the parents to get the cereal. The brief for this packaging design was to create a new perception for cereals and make them seems healthier. Thus, the brand will enhance customers attraction by using Disney characters. The designs should persuade both the parents and young children. The ďŹ nal aim of this is to try and remove this stigma relating to unhealthy cereals and Disney.
