Best Practices Mouse Concept
Transcript of Best Practices Mouse Concept
We researched many mice when looking throughout the market – here are just a few of the products we looked at;
Fujitsu M440 Wired Optical Mouse Eco
Wood Based MaterialMade from 100% bio material with PVC free cable
M440 ECO works on nearly every surface
It features two buttons and one scroll wheel button
The human-centric shape makes it comfortable
for both right and left-handed users
M440 ECO is equipped with the convenient USB Plug-Play with 1-click fast connection
Product Design Spec.
AIMS, OBJECTIVES AND PERFORMANCE:
• To create a computer mouse with zero impact on the environment:
•Easily manufactured (reducing cost & environmental impact)
• Cheap enough for the younger generations (survey)
• The mouse will be a easily chargeable wireless device with (----) functions
• Aesthetically pleasing • Eco-friendly • Ergonomically user-friendly
• (--x--)mm and 55-120grams
• Plastic to allow colourant additives and enhanced properties by making into alloys
• Injection moulding – cheap
• Can be made slightly rough on the surface to increase precision of mouse and reduce chances of slip
Product Design Spec.
Packaging must be recyclable (BS EN 13429: 2004)
BS EN ISO 14042:2000
Environmental management. Life cycle management. Life cycle impact assessment
Reliability of systems, equipment and components. Guide to the demonstration of dependability requirements. The dependability case
For this assignment we have been asked to design an innovative “zero impact mouse” using “best practices” in terms of research and design. The product must have low to no impact on the environment. We are going to design the mouse using Creo Parametric and then scrap engineering to produce a model.
Zero Impact Mouse.
Product Design Spec.
TARGET PRODUCTION COST
No more than £10 and to be sold in retail for £10-15 as 70.59% of people we asked said they would spend £5-£20
• Long product life span as eco-friendly products are being more and more desirable
TASK ANALYSIS, ACTION PLAN AND GANTT CHART:
• Primary and Secondary Research – Surveys,market research etc.
• Initial designs
• Creo modelling
• Adaptation of models – Final idea
The average person spends 20+ hours on the computer per week
(960+ hours a year).
3000 hours service life (roughly 3 years)
The casing of mouse should be partially waterproof/water repellent to stop damage to the components by sweat etc.
Must also be recyclable and should protect the mouse if it’s thrown or dropped from 5m away
This Gantt chart shows the basic layout for how we would manufacture our mouse

Ergonomics are very important as it will reduce
the amount of stress and pressure on the hand
and the joints. This is imperative because people
who work long hours on the computer may develop
carpal tunnel syndrome or other health problems due to the prolonged use of a badly designed mouse.
How a Hand sits
naturally on a
Mice Nowadays come in a variety of shapes and
As a group we decided the mouse was
flawed in a fundamental way,
as when the hand is in a natural
position it is in more of a handshake
position rather than “flat” on the desk - as the majority of mice are made today.
Therefore, we decided it was an important feature to include on our design, this would not only improve comfort for our client, but would also make us stand out in the industry.
Do not have the desired properties.
Some benefits to metals.
Easily Machined-But with a downside.
Can be manufactured in many different ways
Heavy and Brittle
Un-comfortable with polishing, sanding and varnishing
-Most fitting material
-Variety of properties
-Can be made into alloys, or use fillers to enhance properties
-So many to choose from
– zero – impact
– Biodegradable polymers and bio-plastics
-Bio-plastics – sustainable, bio-degradable – ideal materials
-Suitable Materials - Cellulose acetate, Polylactide, hydroxypropionic acid
-Polylactide (PLA) ideal – melting temp. 173°C – injection moulded – can be made hard – durable – easily coloured – easily recycled.
From CES selector:
“Polylactide, PLA, is a biodegradable thermoplastic derived from natural lactic acid from corn, maize or milk. It resembles clear polystyrene, provides good aesthetics (gloss and clarity), but it is stiff and brittle and needs modification using plasticizers for most practical applications. It can be processed like most thermoplastics into fibres, films, thermoformed or injection moulded.”
There is a possibility to add fillers additives to the material which can help stop it biodegrading as it is a biodegradable polymer.
Products Made from Polylactide.
Key Polylactide Properties.
Density: 1.2513 k/m^3
Price: 1.67 per KG
Compressive Strength: 60 HV
3 Programmable buttons
Large Left and Right click buttons
Plug and Play feature - 1 click setup.
Ergo Mouse Properties.
Ergo Mouse II Properties
3 Programmable buttons
Wired - requires no batteries or charging.
Plug and Play feature
Change sensitivity button, in order to use even less electricity.
From Our Research we have discovered;
- Our Main aim will be ergonomics, trying to make
the mouse as comfortable as possible is key.
- Our Chosen Material will be Polylactide - it is strong,
easily colored, recyclable and has very little impact on the environment.
- The mouse cannot cost more than £20, and also needs to be not only wireless, but also, work every single time, quickly and easily.
- Injection molding is our most likely form of building our mouse.
- PLA is a cheap material, so if we were to manufacture this mouse, we could make a substantial profit.
- Ergonomic design
- 3 programmable buttons
- Scroll wheel.
-Less plastic used.
-Rubber and Plastic
Casing to improve grip
- Large body, easy for gripping
- Ergonomic Design
-PLA with Rubber cover for grip.
- Sleep button
- Change Sensitivity button
- Ergonomic Design
-PLA cover with Rubber for grip.
-3 Programmable buttons.
-Sleep Mode Button.
- High DPI
The Design Process.
Majority only use their mouse for general use
Wireless Capabilities very important
Price, no more than £20
Design not as important as first thought
Needs to function every time
Needs to able to set up easily
A more eco friendly mouse is a preferred selling point
People spend 20+ hours on the computer a week
4-6 years is the expected life of a mouse
Predominantly right hand users
The generic mouse design is desired
Wireless is important
Packaging sells the product well
Extra buttons are important
An aesthetically pleasing mouse is desired by most
Our finished design meets most of the standards of the PDS.
It is biodegradable, recyclable and easily manufactured (injection moulding).
It has been designed specifically to be ergonomic and this also makes it aesthetically pleasing.
Its is manufactured from polylactide which allows additives and fillers to preserve the product from sweat/water/vapour
The material is cheap along with the manufacturing which allows our mouses' RRP to be between the set prices of £10-£15
A list of features our packaging contains;
- Made from Recycled Corrugated Cardboard; Eco-friendly; easily printed on; Strength; Lightweight; Recyclable.
-Design; Aesthetically pleasing to open; Mouse and wire fit snug in the box to create less packaging.
