Problem
SANITAS
Cardiac Arrest is the most common medical cause of death in athletes. Sudden Cardiac Arrest in young athletes is usually caused by a structural or electrical abnormality in the heart. These abnormalityies often remain undiagnosed and may be unknown to the athlete. Left unmonitored, this creates a huge risk to the athlete’s life.

PROJECT 04 - AIRBNB HUB THIS PROJECT WAS PART OF A DESIGN WEEK AT LOUGHBOROUGH DESIGN SCHOOL DURING MY FINAL YEAR. I RECEIVED A LIVE BRIEF FROM DCA INTERNATIONAL AND I PRODUCED THE FOLLOWING DELIVERABLES. THE BRIEF WAS TO TAKE A SERVICE-BASED BRAND AND PROPOSE A PHYSICAL PRODUCT THAT WOULD AID THE BRAND IN ENTERING THE NEW POST-COVID WORLD. I CHOSE AIRBNB.
Communication between hosts and their guests •
Guests get in touch to raise an issue or ask you a question. Sometimes these will be fair and understandable. Other times they may be petty, silly or obvious.
•
Lack of or delays in communication can cause the host or guest to change their plans drastically causing unrest in the relationship.
•
Information sharing about the house (operation of washing machine, location of heating, basic house rules, local amenities etc).
02 / INITIAL QUESTIONS • • •
AIRBNB HUB
04
01 / PROBLEM
Can unnecessary questioning be reduced? Could the host supply more information about the house? Can clarity in communicaiton be achieved?
03 / PRIMARY & SECONDARY RESEARCH METHODS
04 / KEY INSIGHTS - DESIGN DIRECTION • • • •
There is unwanted communication between the host and guest that could be avoided with the introduction of an information hub. There is often a language barrier between host and guest which can cause confusion and frustration Keys are often lost or misplaced by the guests. The host and guest could be an adult of any age - design must be inclusive.
05 / DEFINE, DEVELOP & IDEATE WEBSITES
- Airbnb as a brand. (brand identity, ethos, perception) - Learning about the 2014 Rebrand. - Identifying User and Market. - Outlining issues currently faced by Airbnb, hosts and their guests. - Researching similar solutions and competitive products.
INTERVIEWING AN AIRBNB HOST
- Used to gain a detailed understanding of what issues Airbnb hosts face. - Confirmed that the problem identified is legitimate and worth solving. - Insights into habits adopted by the host and guest throughout stays.
ARTICLES
- Used to gain a greater understanding on what issues Airbnb faced during the pandemic. - How service-based companies adapted and overcame Covid-19 - What a hybrid model will look like for service based companies and how they will move into a “New Normal”.
TASK ANALYSIS
- Used to gain insights on the Airbnb process that host and guest go through every rental. - Visualising and targetting problem areas in the renting process
06 / SOLUTION
Design an information hub that is able to fit into any Airbnb environment around the world. The hub would be set up by the host and it would contain all vital information about the house (appliances, house rules and location of heating etc.). The hub would also contain information about local amenities and the local area. It will feature a language option so that the guest can select their native tongue and avoid confusion when reading the information. This will provide independence to the guest and alleviate excessive communication between the host and the guest. The guest will be able to contact the host incase of emergency via a button on the hub, this means that the host’s phone number remains a secret to the guest.

PROJECT 05 - KITCHI THIS PROJECT WAS A ONE WEEK LONG DESIGN WEEK AS PART OF MY 2ND YEAR AT LOUGHBOROUGH DESIGN SCHOOL. I RECEIVED A BRIEF FROM DESIGN REALITY AND HAD A WEEK TO MEET THE BRIEF AND PRODUCE THE FOLLOWING DELIVERABLES. THE BRIEF WAS TO DESIGN A DISABILITY AID USING A SINGLE 3D PRINTABLE PART. THE SOLUTION THAT I DESIGNED WAS A KITCHEN AID FOR PEOPLE SUFFERING WITH ARTHRITIS. COOKING BECOMES VERY STRESSFUL AND POSSIBLY SCARY WHEN YOU CAN’T HOLD OR GRIP THINGS WITH EASE. KITCHI TAKES ALL THAT STRESS AND FEAR AWAY.

The first stage of manufacturing was to take the CAD files of the mould and cut them out using the CNC router.
PRESERVE
We first cut it out of foam to check it worked and then the aluminium was used. In order to make the various inserts, a mixture of machines and processes were used. Including a milling machine, a pillar drill, a surface gridner and various hand tools. Once the inserts were made accurately to size, they were polished before being placed into the mould ready for injection
Once the mould and inserts were polished they could be assembled and clamped together. THe holes for the insert pins then needed to be drilled and reamed. Cutting compound CT-90 was used to keep the reemer cool and not cause damage to the cutter.
The Aluminium was cut on a XYZ CNC mill which used coolant to keep the cutter from over heating. The two mould halves were then ready to be polished and prepared to be used in the injection moulding machine. The mould needed 5 inserts in order to be able to inject properly. These were all made by hand
After the holes were reamed the insert pins could then be assembled into the mould and hit into place using a mallet. The mould was now ready to injected
MANUFACTURING
PRESERVE
06 The mould design is simple and effective and injected very successfully. Once injected the widget could be removed from the mould and the inserts taken out ouf their allocated places.
This injection moulding process was to simply prototype the design of the toothbrush. If this was to be made for mass production it would be made from HDPE Ocean Plastic, which is the material that Preserve use for their products.
Multiple widgets were able to be made. Using different pressure and speed setting on the injection moulding machine to ensure the highest quality finish possible.
The two parts of the widget could then be finsihed using a scalpel to remove any flash from the injection process. The bristles donor part could then be placed into its slot to complete the widget and ready to be used as a toothbrush.
Once finished I took part in a group presentation of our widget and accompanying poster to the module leaders of this design project.
Along with the poster; the mould, the completed widget and the widget after injection were all presented.
