Brief概要

ANGLE CHANGE AS A PHYSICAL INTERACTION

How can a phone stand make frequent repositioning stable, legible, and satisfying with one hand?

For video calls and everyday desk use, the side grip gives angle adjustment a dedicated point of control. Rough assemblies explored the support and grip arrangement; printed components brought the toothed interface into a complete stand. The design keeps the moving parts visible so the hand input and platform response can be read together.

The side grip gives the adjustment a clear point of control while the toothed edge makes each change readable.

The platform, support body, and rotating interface were developed as one assembly rather than separate styling parts. The layered side study records how the phone surface moves while the base remains planted.

MECHANICS BECOME THE AESTHETIC

Repeated teeth, exposed wheels, and a ringed grip make the adjustment system the product’s visual identity.

The loose blue gear and toothed strip isolate how the teeth meet. The assembled details show the same question in context: how the side control, moving platform, and fixed support fit together. Repeated teeth and exposed wheels then give the stand its visual character.

From Sketch to Fit从草图到配合

THE FORM FOLLOWED THE ADJUSTMENT

Each model makes a different design question visible: movement, support, transmission, or assembly.

The sketch explores angle and rotation options. Two rough assemblies compare platform proportions, support geometry, and side-control arrangements; the exposed cardboard mechanism makes the toothed contact accessible. Peer feedback and repeated prints informed the fit, while the SolidWorks model brought the components together before the final black-and-white assembly.

The resolved prototype keeps every adjustment component visible and reachable.

The final contrast between black structure and white controls clarifies what stays fixed, what moves, and where the hand engages—turning the mechanism into both interface and character.
