Aergo ps packaging

date: 2020
project duration: 8 weeks

Aergo PS is an automated postural management system utilising patented technology of a network of smart air cells positioning the user in a healthy posture.

Project brief: To design a packaging for Aergo's flagship model (Aergo PS) protecting the device during transport, with emphasis on an intuitive and wheelchair user friendly design and a budget of £50 per unit.

Skills developed: Industrial and graphic design skills.

user research

Key insights:

1. Unpackaging would probably be done on the seat level - unlike abled users who would place a heavy package on the floor, due to a seated position wheelchair users will more likely place it on a surface on the seat level.

2. Full visibility required - during the unboxing maximum visibility is advantageous for assessing the size and weight of the part.

3. Both hands required for transportation - while moving around the house/ a shop, many wheelchair users place objects on their lap to free up their hands for transportation.

prototyping & concept development

The prototyping stage began with prototyping the Aergo PS components as the access to original parts was not possible due to Covid-19 lockdown measures.

One of the prototyped concepts (bottom left picture) turned out to have very flimsy feel due to consisting of many separate walls connected. As the original parts would be much heavier than the prototyped version, the packaging have to be sturdier. Fortunately the second prototype provided a much better experience. The main structural difficulty in the second prototype is the possibility of buckling of the front wall (picture on the right). To prevent this, the walls were doubled and a separator between these walls was added to redistribute the force.

final design

applicator

date: 2019-2020
project duration: 7 months

Wearable healthcare sensors are a growing segment of the healthcare industry. One of the technologies developed in this area is microfluidic droplet sampling. This work is based on and part of the research carried out by the Microfluidic Research Group at University of Southampton, which is developing such a device. It utilises microdialysis technique to sample droplets later analysed by the device. Microdialysis is a sampling technique commonly used in vitro. There is a growing use for this technique in point-of-care monitoring systems (for example in continuous microfluidic sensing devices).

Project brief: To design and develop a microdialysis probe applicator, to be used by healthcare professionals as well as patients and caretakers.

Skills developed: Multidisciplinary research,

procedure reseach

Key insights:

1. The insertion has to be safe to perform by a non-professional - the applicator should produce the same result regardless of the user's prior experience and skill in this procedure.

2. User shall able to perform the insertion one handed - as a popular site for sampling ISF is on an arm, to ensure user's independence this mechanism has to be operated one handedly.

3. The applicator shall be designed against a negative outcome - to ensure users safety, safety measures are used to prevent the mechanism acting out of order.

catastrophic
(biology game)

date: 2018
project duration: 10 weeks

Catastrophic is a card game designed to support joyful learning of the bio sciences, aimed at students aged 16 to undergraduate level. It was created based on a level 5 Animal and Plant Biology module and covers most of its content. It allows for players on different level of knowledge of biology to gain deeper understanding of the mechanisms in nature.

Project brief: To design a collectible card game that teaches undergraduate biology with a focus on supporting revision, retaining, and building a mental model of the connections of basic Animal and Plant Biology – a 30 credit module at the University of York.

Skills developed:

user, games & biology research

At the beginning of the project we undertook research into the potential users, game design as well as the biology module we intended to cover.

Key insights:

1. Flexible number of players - can be played at a house party or on a study date.

2. Accessible to all - game to be played by professors, students, friends and families. No prior knowledge of biology is required.

3. Relatively short gameplay - to ease memorisation, through engaging with the game for a shorter period of time bur more often. Shorter games are also easier to fit into busy student schedules.

final product

Catastrophic was released to biology students at University of York in 2018. The full deck has 240 cards, 120 in the basic deck with three 40 card expansion packs released along with the module content during the academic year. The game has since been updated and can be downloaded for free here.

hydroponic garden

date: 2016-2017
project duration: 5 months

Engineers Without Borders UK is part of a global movement engineering a better future which aims to inspire, enable and influence the engineering community to serve all people and the planet better than ever before.

Project brief: To design, prototype and test a gardening system for urban users.

Skills developed:

user research

Key insights:

1. Automated water delivery - for the busy, city based users we design, the garden must be able to sustain its water levels.

2. Recycled parts - due to the nature of the project we challenged ourselves to use recycled objects for the parts.

3. Plants of smaller sizes - produce a list of suitable plant options.

design development

During the design process we focused on the design which would take minimal space. We also had to take into consideration the parts we were able to find, aiming to make the garden system with as many recycled parts as possible. Fairly quickly we came across bicycle wheels, which were became the starting point for the rest of the design. The use of wheels allowed us to consider rotation for water delievery, which turned out to be an efficient and elegant solution.

prototype

responsive system

date: 2019
project duration: 8 weeks

'Flappy' is a responsive mechatronic system designed to dynamically respond to proximity and luminosity sensors.

Project brief: To design, build, program and test a prototype a mechatronic system that senses and responds to the changing characteristics of its local environment, including the proximity of moving objects. The system is to be unique to its specified location (each group was randomly assigned a specific location) and should consist of mechanical parts whose action is controlled by an integrated electronic computational system. It should be expressive and engaging by visually communicating its responses through physical movement, be reliable andhighly refined.

Skills developed: Ability tu turn an idea into reality.

line launcher

date: 2018
project duration: 2 weeks

A Line Launcher is a device used to fire a rope from one ship to another at sea or for water rescue. This project was based on IMechE Design Challenge 2016.

Project Brief: To design, build and test a small scale indoor device to fire a squash ball attached to a line over a distance up to 6m. A target will determine which device delivers consistent accuracy and precision.

Skills developed:

testing rig

To replicate 'ship to ship' the testing rig was set up with two tables approximately 1500x750mm.  The base and target will fit between the guide rails allowing the base and target to be clamped in any position on the tables.

Competition Conditions: A firing range was set up in an indoor space i.e. lecture theatre, with a firing line and target area. A Safe Firing Area was outlined up to 2m behind the firing device.  The target area was be a 600 x 600mm rectangular 3 x 3 wire grid raised 450mm from the table.  The distance was determined by a random draw between 2 and 6m with 0.5m interval. Scoring will be judged by the grid space the ball first passes through on their target. Range is the distance from the device firing line (the front edge of the mounting base) to the center of the highest scoring region of the target.

IDEATION

This task deals with energy storage and projectile trajectory. The requires a controlled and safe release mechanism which allows for reliable results.

As the distance options are discrete, we wanted to make the system more reliable by correlating preset spring compression forces with the possible distances.
