The following images belong to an academic project, for the Product development Design studio, at Politecnico di Milano. The goal was to redesign a hardware tool based on the way of use: identifying elements and improving the communication to the user.
The starting point was Bosch GBS 75 AE Belt Sander which usability and visual communication were analyzed. Finally a Gaver's scheme was used in order to identify elements either false affordance, hidden affordance, perceptible affordance and correct rejection that could be affecting the language perceived by the user.

Starting point: Bosch GBS 75AE Belt sander.
Use analysis - Original Belt sander.
Modeling - Using polystyrene foam.
Fixing of buttons and interaction elements (3d printed).
Modeling - Covered in stucco to get smooth surfaces and seal the foam.
Joining parts and ensuring dimensions.
Redesign - Final model.
The redesign of the hand belt sander features 6 strong improvements from the original model;
- The handle and the stem had been modified due to the nature of the movement applied when using the tool.
- The stem has been "integrated" to the main body in order to allow a better handling when reaching difficult areas.
- The trigger has been "splitted": an action / unlock button and a lock switch.
- The speed regulator is in the same plane of the movement made by the belt when spinning.
- The red lever suggests the movement required to release the grip of the sander when replacing.
- The knob in the front regulates the position of the belt.

Using - Action with both hands on the handle and the stem.
Pulling the lever will release the grip of the sander for replacement.
