Internet of Things

Njord Brief

Problem

To identify a user need within a clearly defined situation that could be resolved with a future “Internet of Things� product in relationship with an app.

Two thirds of people with asthma experience worse symptoms in areas of heavier pollution. As such, this leads to a higher risk in asthma attacks as well. Current asthma inhalers do not help with this problem, with the solution either being to wear an unsightly mask or reduce time spent in high pollution areas.

Individual project 9 weeks

2/3 asthmatics have an increased risk of asthma attacks in areas of pollution.

4


Initially, existing products were reviewed to help inspire, as well as limit, the form and feel of the designs through the concept generation process.


Ideation & Development

For this project, sketching and the generation of new forms was paramount. Multiple sketch models were created to help find out which forms were suitable through more user testing.

The target users were questionted when forming ideas for this brief. This gave me multiple points to consider such as placement of the components and semantic design.

6


User testing of sketch models allowed for refinement of ergonomics. It was found that using the inhaler in the opposite position felt more comfortable due to the tag.


8


The common blue colour of preventer inhalers was kept as to ease identification of the use of the product. Branding was also given to the product, thus helping to give the inhaler an identity.

Prolab board was used to create the final model. A heavy attention to detail was needed to ensure that the final model was as realistic as possible. Surface finish, part lines and precision of component fits were all taken into account when modelling.


Scenario of Use Njord is placed in the users hand as such.

The user feels an asthma attack coming on due to particulates in the air.

To help avoid areas of high pollution the air quality checker can be used.

10

The checker is pinned onto th user.


To replace the cartridge the user opens as such.

The user inhales whilst pressing down on Njord. Data is mass collected about where users experience asthma attacks Warning! High pollution

he

Njord checks for particulates in the air.

Data from all Njords is collected to create a map of pollution hotspots and areas where Njord is used. This allows users to avoid these areas with warnings of pollution.


Njord is a smart asthma inhaler with built in air quality monitor that can be detached and pinned on to the user. The product is to be used in conjunction with an app which provides the user with air quality data around their location.

Smart City App

Pitch Brief

Research

Design a smartphone app which will improve upon the lives of those living in “Smart Cities�.

Through user research it was found that there are multiple pain points when trying to set up a game in a public space. For example: Not finding enough people to play a full game. Not bringing the right equipment. Knowing which pitches are free.

Group project 10 weeks

Solution: A smartphone app which uses smart city data to help plan and join games in public spaces for its users.

14


Pain points were discovered using a plethora of methods. Initially the whole group partook in a user journey map. Everyone was encouraged to provide as many ideas on what the user might be thinking, feeling or doing.

Pain Points:

Other individual research methods such as shadowing & interveiws were conducted.

Not being able to play due to the fact there aren’t enough people for a full team.

From here, certain pain points were highlighted as the main focus for the app to solve.

Friends having conflicting schedules. Frustration with travelling to a space just to find that it’s busy. Feels annoyed when someone forgets equipment that they need to play such as a tennis racket.

“ I’d really like it if people actually turned up on time ”


Persona: Liam Taylor 20

“ Getting people together for a kick-about is a real pain. Often we don’t have enough players ”

Goals • Liam wants to use the app as a way to meet new friends with similar interests that he can socialise outside of playing sports. • He wants to use the app as a way to get back into sport and feel healthier in himself. Liam Taylor is a 21 year old Geography student at Manchester University and is originally from Newcastle. Unlike a lot of his friends, Liam is not on placement. This means that Liam currently has few friends at University with him. Liam like to unwind by playing football in the park, which is about 20 minutes away by foot.

16

• He wants to feel confident that there’s going to be enough people to play with and that he won’t have to wait around for them to arrive. • Liam wants a sense of satisfaction organising sporting events that people will enjoy.


Dynamic Intuitive Efficient Modern Social

Our concept vision.

After defining a scenario of use, user testing and development could begin.


Scenario of Use

It’s 4pm, Liam and his flatmate have had a hard day of lectures and want to have a kick about. The problem is they aren’t sure where to play, and wish they had more players. He launches Pitch and clicks the icon to host his own game. This gives Liam information on available public spaces nearby.

Pitch uses “Smart City” Data such as movement sensors in public spaces as footfall information to predict how busy the space is likely to be.

Once Liam has a game sorted, the app will invite his friends to join the game. This shows up as a notification on their phones.

18

Liam meets up with everyone who joined the event and plays a game of football. Afterwards he adds friends the other new players as he would like to play with them again.

Liam has invited his friends however he still would prefer more players. He makes the event public. This allows other users to request to join the game.


User Testing

A wire-frame was created, which was then made into a paper prototype, which was tested by the target audience.

A section of the wire-frame showing how the user would navigate throughout the app. User feedback was collected and used to improve upon the experience.

“ The click-able icons are not well defined. I had trouble knowing what was a button ”

Improved interfaces following user feedback.

“ The map is a cool idea, I think it would actually motivate me to go out more ” “ I expected the exit button to be on the other side ” “ The bottom icons are quite squashed, I feel like I would hit the wrong one ”

Design Week

Anchor Brief

Problem

Use “live hinges� to design a home-ware product for student accommodation. The product must be capable of compact storage.

Living in student accommodation can be strenuous. Any damage or abrasion caused to the walls may result in a fine. This means that storing a bike can be hard; wall-mounting a rack or leaning the bicycle against a wall is risky. The majority of storage space in student housing is also very limited.

Individual project 7 days

Solution: A fold-able and portable bike stand lies on the floor.

22


Persona: Jen Adams 19

Jen studies Biological Sciences at Warwick University. She regularly makes the trip to lectures, shops and other friend’s accommodation via her road bike. She finds that when cycling over to her friend’s, they can sometimes be adamant to let her lean her bike against indoor walls as it may cause scuff marks. She also does not like locking the bike Goals: Jen would like a way of holding her bike upright without relying on walls. The solution should be cheap and portable, allowing her to use the product at her friend’s houses.

The problem

“ Some of my friends don’t appreciate me leaving my bike against their walls when I visit ”


Quick ideation & rapid prototyping Existing bike stands were used as inspiration to help form the initial ideas for the design of this product. It was important to incorporate the live hinge component as a main part of the design.

24


The solution

Due to the quick turnaround, rapid prototypes made out of cardboard and foam-board were made to test the design. It was found that creating a latch that hooked onto the gap was structurally stronger than other considered designs. Creating these models also helped with visualising the product.


Renders of Anchor created in Keyshot.

26


Anchor is a portable bike stand made for students. The main body is made of polypropylene, with a steel insert in the bottom face to secure the product.

Latch secures Anchor in its stand position and also allows for the product to be hung up.

Live hinges allow for a sturdy uni-body design which can be thrown into backpacks.

Rubber feet grip to the floor.

Scooter Brief

Problem

Use SolidWorks to create an assembly of a scooter. The final model must include at least one sheet metal part.

Bike and scooter parts were analysed to ensure that the components made for this scooter design were accurate to real life.

Individual project 6 weeks

28


Zebra stripe analysis allows for curvature to be accessed.


EPI for Design

Plant Pot Brief

Process

To create a functional artefact of an electronic embedded system. The circuit should incorporate a sensor, output and LCD.

To create the code and correct circuit for the system, the artefact was defined as a problem and flowchart in order to determine the inputs and outputs of the system:

Paired project 4 weeks

Input - Moisture sensor Outputs - Water pump and LCD From here code and hardware were created in a cyclical manner through multiple simulations, debugging and hardware debugging.

Wet soil Pump off

Dry soil Pump on

A PIC18F45K20 micro-controller was used to control the whole system. The moisture sensor, when placed in soil, will detect the moisture level of the soil. The micro-controller will determine the soil to be one of 5 moisture levels, based off the voltage given by the analogue pin of the moisture sensor. This then causes the LCD to display the relevant information whilst the pump either turns on or off.

32

After testing the final code and circuit, the components were moved and soldered to a PCB and placed in a specially made, 3D printed case.


DMT

Widget Brief

Process

Respond to the opportunity to develop a mould tool design for a promotional polymer give away widget.

The designed widget must be functional, highly promotional and feasible with the constraints of the mould creation process.

Individual project 4 weeks Work in Progress - Moulds to be made

34


Brand Research

Canon EOS is the companies SLR camera series. These cameras are aimed towards those who wish to have more control over the photographs they take. The EOS range are also the only Canon cameras to feature a hot shoe. Using this knowledge it was decided that a spirit level widget, giving the user finer control over photos, will be made that can fit into the hot shoe of the camera.

Canon EOS is an SLR camera series for those who want more control.

Sketches were created to document the process of creating and overcoming the challenges of creating the widget and mould tool.


Plastic Analysis

After the final design was chosen, plastic analysis was performed on the SolidWorks models of both components and the runner. The analysis tells us whether the model will fill or have any shrinkage deformations after cooling. From the shrinkage analysis it can be seen that part of the underside may show shrinkage, however this is not to worry about as this the amount is minimal. Fill time also shows us that the there is a fairly even spread and cooling of the plastic within the mould.

36


Multiple engineering drawings were made to help in the manufacture of the mould.

Hobbies

Photography In my free time I enjoy taking photos; an escape into whichever world or story I want to create. From this hobby I have gained an insight into what it takes to create a compelling shot when taking photos of my models.
