Detachable Mouse Back Cover With Replaceable Pads
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mouse devices require pads of the same material on both sides, limiting their usability and requiring replacement when worn out, which restricts operational flexibility and leads to premature device discard.
Innovation Solution
A mouse device design featuring a detachable back cover with slots and hooks, allowing for easy replacement of pads with different materials, ensuring prolonged device life and flexibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the mouse device uses a fixed back cover with pads on both sides, then the device structure is simple, but the pads cannot be replaced when worn out or for different material requirements
Solution Approach 1:
The back cover is divided into a fixed portion and a detachable portion, allowing the pad assembly to be separated and replaced independently. This segmentation enables users to replace worn pads or switch to different pad materials without replacing the entire mouse device, resolving the contradiction between adaptability and structural simplicity.
Solution Approach 2:
The back cover transitions from a static fixed structure to a dynamic detachable structure. The detachable back cover can be removed and reattached as needed, providing operational flexibility while maintaining a relatively simple overall device structure. This dynamic design allows pad replacement without requiring complex mechanisms.
2Adaptability or versatility
If the mouse device requires symmetric pad configuration with same material on both sides, then the structure is simple, but the operational flexibility is limited
Solution Approach 1:
By segmenting the back cover into detachable portions, the patent enables different pad materials to be used on different sides without requiring complex symmetric design. Users can attach different pad assemblies to the detachable back cover based on specific operational needs, achieving material variety while keeping the configuration relatively simple.
Solution Approach 2:
The detachable back cover serves multiple functions: it can accommodate different pad materials, be removed for cleaning or replacement, and be reattached to restore functionality. This multi-functionality allows a single device structure to support various pad configurations without requiring multiple specialized devices.
3Duration of action of stationary object
If the mouse device uses traditional fixed back cover, then the manufacturing is simple, but the device lifetime is limited due to pad wear
Solution Approach 1:
Segmenting the back cover allows the pad assembly to be replaced independently when worn. This extends device lifetime by enabling users to replace only the worn pads rather than discarding the entire device, while the segmented design remains relatively simple to manufacture compared to completely removable shell designs.
Solution Approach 2:
The detachable back cover enables selective discarding of worn pads while recovering and reusing the main body and other components. This extends device lifetime by allowing users to replace only the consumable pads rather than discarding the entire mouse device, balancing extended durability with manufacturing simplicity.

AI summary
A mouse device used on a surface includes a main body, a circuit assembly and a back cover. The main body includes a bottom and at least one slot formed at the bottom. The circuit assembly is disposed within the main body and executing a default function of the mouse device. The back cover comprises a first side, a second side, at least one hook at the first side, and a plurality of pads at the second side. The back cover contacts with the surface via the plurality of the pads, is disposed detachably at the bottom of the main body and is buckled to the slot by the hook.
