Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mouse pads lack enhanced features beyond providing a smooth surface for optical mice, with little research on incorporating lighting effects.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a lighting assembly is added to the mouse pad, then the lighting effect is enhanced, but the device complexity increases
Solution Approach 1:
The patent combines the lighting assembly with the mouse pad structure by sandwiching the light-transmission body between the base and the mat, integrating multiple functions (light emission, structure support, mouse surface) into a unified device rather than adding separate components
Solution Approach 2:
The light-transmission body serves multiple purposes: it transmits light from the light sources, provides structural support as part of the sandwiched assembly, and its peripheral edge portion serves as both a light output surface and a structural boundary of the mouse pad
2Illumination intensity
If light sources are distributed along the substrate, then the illumination uniformity is improved, but the manufacturing precision requirements increase
Solution Approach 1:
The lighting system is segmented into multiple discrete light sources distributed along the elongate-shaped substrate, with each light source contributing to a specific segment of the peripheral edge illumination, allowing for modular assembly and reduced precision requirements for individual components
Solution Approach 2:
The light sources are distributed non-uniformly along the substrate length, with higher density at certain regions to compensate for light attenuation and achieve uniform overall illumination of the peripheral edge, applying different densities locally to achieve global uniformity
