Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional light emitting mouse pads have complex manufacturing and assembly processes due to embedded light sources, which require improvements for simplification.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If embedded light sources (LED or CCFL) are used in conventional mouse pads, then light emission function is achieved, but manufacturing and assembling processes become complicated
Solution Approach 1:
The patent extracts the light source from the embedded configuration and relocates it to a lateral position outside the mouse pad surface. The light source is positioned at the side edge of the light guide plate, separating the illumination function from the pad structure, thereby simplifying manufacturing and assembly while maintaining light emission capability
Solution Approach 2:
The patent introduces a light guide plate as an intermediary component between the lateral light source and the mouse pad surface. This mediator transfers light from the lateral source uniformly across the pad surface, achieving the illumination function without requiring embedded light sources, thus simplifying the overall structure and manufacturing process
2Ease of manufacture
If lateral light source is used without shading structure, then light can enter the pad easily, but light passes through the top of the light source causing non-uniform emission
Solution Approach 1:
The patent applies local quality modification by adding a shading structure specifically at the top region of the lateral light source. This localized shading element blocks light from passing through the top of the light source while allowing light to enter the pad from the lateral direction, creating uniform light emission only where needed without affecting the overall ease of light entry
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design simplifies the manufacturing process and provides a uniform light emission by guiding light from a lateral source through the light guide plate and shading structure, enhancing user experience while reducing manufacturing complexity.
Implementation Method 1
a light guide plate, and a shading structure. The light guide plate is installed on a side of a pad, and the lateral light source is installed at a side edge of the light guide plate

AI summary
A mouse pad with a light guide function includes a light guide plate installed on a side of a pad, a lateral light source installed at a side edge of the light guide plate, a shading structure installed at the top of the lateral light source and disposed together with the lateral light source on the same side of the light guide plate, and the mouse pad can guide light of the lateral light source through the installation of the shading structure without passing from the top of the lateral light source, so as to simplify the manufacturing process.
