Wireless Mouse Switch Module Integrating Power and Pairing Functions

Solution Overview

Problem

Conventional wireless mice, especially Bluetooth models, have higher manufacturing costs and occupy more space due to separate structures for power switches and pairing keys, which are not efficiently integrated.

Innovation Solution

A switch module with a cantilever arm and operation rod that slides between power on and off positions, integrated with a circuit board containing a power switch and a pairing switch, allowing for a single mechanism to control both functions within a smaller form factor.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If separate structures for power switch and pairing key are used, then each function can be independently controlled, but manufacturing cost increases and space occupation increases

Engineering Contradiction:

Improveindependent function controlVSAvoidstructure complexity

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The patent combines the power switch and pairing key functions into a single integrated switch module. The operation rod serves dual purposes: when pushed to the second position, it simultaneously activates the power switch through the first extending foot and triggers the pairing function through the second extending foot pressing the pairing key, thereby reducing structural complexity while maintaining independent function control

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The switch module is designed with multi-functionality where a single operation rod controls both power switching and pairing operations. The cantilever arm structure with multiple extending feet enables one component to perform multiple functions, reducing the need for separate structures and lowering manufacturing costs

Inventive Principle:

Principle #6Universality (Multi-functionality)

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The switch module employs a nested structure where the first and second extending feet are integrated into the same cantilever arm assembly. The pairing key is positioned within the housing structure, and the operation rod nests within the housing, allowing compact arrangement that minimizes space occupation while maintaining functional independence

Inventive Principle:

Principle #7Nested doll (Nesting)

AI summary

A switch module includes a pressing button and a circuit board. The pressing button includes a fastening element. The fastening element extends outward to form a cantilever arm. The cantilever arm protrudes downward to form an operation rod. The operation rod is exposed out of a lower shell which has a first position and a second position. The operation rod slides from the first position to the second position. The other end of the bottom surface of the cantilever arm extends outward to form an extending arm. At least one portion of one end of a top surface of the cantilever arm protrudes upward to form at least one extending foot. The circuit board is disposed above the pressing button. The circuit board is equipped with a first switch and a second switch. The at least one extending foot is corresponding to the first switch.
