ASSIGNMENT 2: BLADE TOOL

The goal of the assignment is to design a hand tool that uses a blade of a predefined shape.

The learning objectives are:

To design a multi-component device with imposed practical constraints.
To produce design alternatives that take into account: functionality, usability and appeal (Perceived value by potential users).
To create awareness of the limitations of rapid prototyping techniques.

A hardened-steel trapezoidal blade that was a by-product of an industrial process was obtained. The assignment is to design a product that uses only 3D-printed components (apart form fasteners) that gives an added value to the blade. The blade may not be altered in any way. The design must allow the blade to be exchanged easily and must contain at least one control element (button, slider, knob, etc.)

Project Debrief:

This project was inspired by the difficulty of opening clam-shell packaging and the ergonomics and ease of use of a staple remover. The idea for this project was to use a pinch grip to puncture the packaging using the blade tool and to pull down to open the package.

The project went through multiple designs and redesigns on paper and with modeling clay. The final product was modeled and based off of a small stapler or staple remover for ease of transportation and ease of use with one hand. This product was entirely 3D printed.

A minor issue that was encountered after fabrication was that the blade would sometimes sink below the depth of the packaging which impeded the cutting ability of the blade. The tool was also very flimsy due to the 3D printed material and sometimes had issues providing adequate support and force against tougher packaging however, this is easily avoided by using a tougher build material or fabrication process.
