Light-emitting Pad Structure with Replaceable Light-guiding Strip
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional light-emitting mouse pads face issues with broken or uneven sewing threads and the irreplaceability of light-guiding strips, leading to low yield rates and environmental concerns.
Innovation Solution
A light-emitting pad structure featuring a pad unit with a light-pervious fabric member forming an accommodation bag around the light-guiding strip, allowing for secure positioning and easy replacement, eliminating the need for conventional sewing methods.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If general or overlock sewing means are used to attach the light-guiding strip to the pad unit, then the light-guiding strip can be secured to the pad unit, but the sewing thread may break, become uneven, or become inclined, leading to low yield rate
Solution Approach 1:
The invention extracts the light-guiding strip from the sewn structure and places it into a dedicated accommodation bag formed by the light-pervious fabric member. This separates the attachment function from the fabric itself, allowing the fabric to be securely adhered to the pad unit while the light-guiding strip is independently positioned and replaceable, eliminating sewing-related quality issues.
Solution Approach 2:
The accommodation bag acts as an intermediary structure between the light-guiding strip and the pad unit. Instead of directly sewing the light-guiding strip to the pad unit, the bag provides a secure enclosure that holds the strip in place, mediating the connection and eliminating the need for direct sewing attachment.
2Stability of the object's composition
If the light-guiding strip is sewn to the pad unit, then the strip is fixed in position, but the strip becomes irreplaceable when broken, conflicting with environmental friendly trends
Solution Approach 1:
The invention segments the attachment system into three independent components: the pad unit with adhered fabric member, the accommodation bag formed by the fabric, and the light-guiding strip. This segmentation allows the light-guiding strip to be independently removed and replaced without affecting the pad unit or fabric member, achieving both stability and replaceability.
Solution Approach 2:
The invention transforms the static, permanent sewn connection into a dynamic, replaceable arrangement. The light-guiding strip can be dynamically removed from and reinserted into the accommodation bag, allowing for maintenance, replacement, and environmental friendliness while maintaining stable positioning during use.

AI summary
A light-emitting pad structure and a manufacturing method thereof are provided. The light-emitting pad structure includes: a pad unit, including a main pad body and a light-emitting module, and the main pad body has a top wall, a bottom wall and a lateral annular wall; a light-guiding strip, bent for being surrounded at a periphery of the lateral annular wall and arranged corresponding to the light-emitting module; a light-pervious fabric member having a middle segment and an outer segment, the middle segment is adhered to the top wall, the outer segment is adhered to the bottom wall, so that the light-pervious fabric member is formed with an accommodation bag arranged to cross the lateral annular wall and enclose the light-guiding strip; and a bottom plate adhered to and covering the bottom wall and the outer segment.
