ReDesign
Hole Punch
The project was to redesign an existing everyday item, creating a CAD model and a prototype of the redesign and a presentation board to explain the redesigned concept.
Design Statements
This project is based on redesigning an everyday office tool; the hole punch.One of the key issues with this device is that it is frequently difficult to align the holes correctly on a standard A4 sheet.
As hole punching is invariably paired with ring binders which come in two or four ring varieties, the punches themselves would need to be moveable to punch as many holes required for the binder.
The design needs a compact solution which should tackle the issues between the user and the paper, ensuring the most efficient means of correctly locating the holes.

Final Design Statements
The focus of the design was to enable the user to easily and correctly line the holes up on a standard sheet of A4. The design achieves this by moving along a metallic cord, with magnets spaced at the appropriate intervals for two or four ring binders, which line up with magnets in the centre pieces. The cord is the length required for a standard sheet of A4 so as to remain taught during use. While the coil mechanism retracts to compact the device into its portable state when over extended.
The design was also meant to be compact and efficient. It achieves this by being the minimum size required to perform its function, it is also light and portable, as it will be made from a hollow bio-plastic and is only 10cm long, making it perfect for pencil cases, pockets and work bags.
The design has the potential to be developed for any standard paper sizing.
