Brief of eco design challenge
Design a sustainable office stationery product
Approach to brief
After a lot of brainstorming and research, the team came to the following conclusions :
everyone in a typical office uses a pen,
Mostly two to three colours were frequently used in a typical multicoloured pen.
Pens should have more ink in them and should last longer
Basic idea involved reducing the amount of colours to three and reducing the amount of moving parts
Extensive amount of sketching and collaborative ideation was done to create a suitable mechanical solution.
Resolution
The final design was created and tested in SolidWorks ( since CAD software could do basic load/pressure testing and simulations )
Aesthetics include a transparent cover to show coloured ink cartridges.
Final design
A conventional pen has four colours and four handles that control each colour.
Final design involved a pen where each different coloured nib was pushed by a single rotating cam ( highlighted in green ). To change a colour, the user has to turn a handle, which is connected to a cam.
This design is not in production.
