Wrist rest and system
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wrist rests provide only cushioning support but lack visual interest and ergonomic enhancement, leading to monotony in user experience.
Innovation Solution
A wrist rest equipped with light sources capable of producing multiple colors, a light guide to diffuse light, and a cushion to conceal these components, providing both comfort and dynamic lighting effects without altering the exterior design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If light sources and light guide are added to the wrist rest, then visual interest and user engagement are improved, but device complexity increases
Solution Approach 1:
The light guide is positioned within the base structure, and the cushion is disposed over the light guide, creating a nested arrangement where components are housed within one another. This nesting approach adds lighting functionality while maintaining a compact form factor and avoiding excessive complexity expansion.
Solution Approach 2:
The wrist rest serves multiple functions: it provides ergonomic cushioning support for the wrist and simultaneously delivers dynamic lighting effects through integrated light sources and light guide. This multi-functionality addresses user engagement needs without requiring separate devices.
2Shape
If light sources are housed in the base structure, then exterior design is preserved, but manufacturing complexity increases
Solution Approach 1:
The wrist rest is divided into distinct segments: a base structure housing the light sources, a light guide layer, and a cushion layer. This segmentation allows each component to be manufactured separately and then assembled, making the complex internal structure manageable while preserving the simple exterior appearance.
Solution Approach 2:
The light guide acts as an intermediary component between the light sources in the base structure and the exterior cushion surface. It receives light from the sources and diffuses it through the cushion, enabling the lighting function while maintaining the original exterior design appearance.
3Shape
If cushion is disposed over light guide to conceal components, then aesthetic appearance is improved, but light diffusion efficiency may be reduced
Solution Approach 1:
The cushion is configured as a diffuse layer that appears opaque or translucent from the exterior, concealing the internal light sources and light guide while still allowing light to pass through and diffuse. This thin film approach maintains aesthetic appearance while preserving sufficient light diffusion efficiency.
