Integrated Switch Module for Bluetooth Mouse
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current Bluetooth mice have a higher manufacturing cost and require more assembly space due to the separate structure of the power switch and pairing button, which increases production costs and design complexity.
Innovation Solution
A switch module design that integrates a button, bracket, and circuit board with a sliding mechanism, where the operating column moves between positions to activate switches for power-on and power-off states, allowing for a single button to perform both functions and reducing the need for separate components, thereby lowering costs and saving space.

Engineering Contradiction Analysis
1Ease of operation
If the power switch and pairing button are designed as separate components, then each function can be independently controlled, but the manufacturing cost increases and assembly space requirement increases
Solution Approach 1:
The patent combines the power switch and pairing button into a single integrated button structure. The button body serves as the outer shell for both functions, with an operating column that can be pressed to trigger different switches depending on the pressing depth and direction. This merging eliminates the need for separate power switch and pairing button components, reducing manufacturing cost and assembly space while maintaining independent controllability of both functions through different pressing operations on the same button.
2Ease of operation
If the power switch and pairing button are designed as separate components, then each function can be independently controlled, but the assembly space requirement increases
Solution Approach 1:
The patent implements a nested structure where the operating column is positioned within the button body, and the first switch and second switch are arranged in a nested configuration. The operating column can press the first switch when moved in the first direction, and press the second switch when pressed downward, with both switches housed within the same button assembly. This nesting approach allows multiple functional elements to occupy overlapping or adjacent spatial volumes, significantly reducing the overall assembly space requirement compared to separate component layouts.

AI summary
A switch module includes an outer shell, a button and a bracket. The button is disposed to the outer shell. The button has a base board. One side of a bottom surface of the base board is recessed in the upward direction to form an avoiding groove. A rear of the bottom surface of the base board protrudes in the downward direction to form a driving pillar. The bracket is disposed under the button. A top surface of the bracket is recessed in the downward direction to form an accommodating groove. A top surface of a bottom wall of the accommodating groove is defined as a stopping surface. The driving pillar projects beyond the stopping surface. A front end of the top surface of the bottom wall of the accommodating groove is recessed downward to form an avoiding plane.
