Composite Key Structure for Wireless Mouse Space Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing wireless mouse design includes an underutilized pairing key that occupies space and affects the appearance and internal structure, as it is rarely used after initial pairing, leading to a need for a more efficient key structure.
Innovation Solution
A composite key structure that combines multiple functions into a single key, utilizing a circuit board with a first and second switch, and movable members to activate both power and Bluetooth pairing functions, reducing the number of keys required.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a separate pairing key is provided on the wireless mouse, then the pairing function can be performed, but the quantity of keys increases and occupies space on the lower cover affecting appearance and internal structure
Solution Approach 1:
The patent combines the power switch and pairing key into a single composite key structure. The first movable member serves as both the power switch actuator and the pairing key actuator through different operational modes (pressing direction and rotating direction), thereby reducing the total number of keys from two to one while maintaining both functions.
Solution Approach 2:
The first movable member is designed to perform multiple functions: it can be pressed to activate the power switch and rotated to activate the pairing key. This multi-functional design allows a single component to replace what would traditionally require two separate components, reducing device complexity while maintaining adaptability.
2Adaptability or versatility
If a separate pairing key is provided on the wireless mouse, then the pairing function can be performed, but the key occupies space on the lower cover affecting appearance
Solution Approach 1:
By merging the pairing key function into the power switch structure, the patent eliminates the need for a separate physical key on the lower cover. The composite key structure maintains a clean, minimalist appearance while preserving the pairing functionality through rotational operation of the same movable member.
3Adaptability or versatility
If a separate pairing key is provided on the wireless mouse, then the pairing function can be performed, but the key affects the internal space of the wireless mouse
Solution Approach 1:
The patent merges the pairing key structure with the power switch structure, sharing common components including the first movable member, part of the circuit board, and housing space. This integration eliminates the need for separate internal space allocation for a distinct pairing key mechanism, thereby optimizing internal space utilization.

AI summary
A composite key structure and a wireless electronic device using the same are provided. The composite key structure includes a circuit board, a first switch, a second switch, a first movable member and a second movable member. The circuit board has a first surface and a second surface opposite to the first surface. The first switch is disposed on the first surface. The second switch is disposed on the second surface. The first movable member rotatably disposed on the first switch relative to the circuit board to activate the first switch. The second movable member slidably disposed on the first movable member to activate the second switch.
