External Battery Module Layout for Fast Mouse Battery Swaps
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wireless mice have a design that makes it difficult for users to quickly replace the battery, as the battery is fixedly disposed inside the casing or stored in a covered slot.
Innovation Solution
A mouse device with a detachable battery module that is connected to the outside of the casing via a connection interface, allowing for easy replacement and eliminating the need for internal space within the mouse.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the battery is fixedly disposed inside the mouse casing or stored in a covered battery slot, then the battery is protected and secured, but it becomes difficult for users to quickly replace the battery
Solution Approach 1:
The battery compartment is segmented into a removable battery cover and a battery holder. The battery cover can be detached from the casing to expose the battery, allowing users to quickly replace the battery without disassembling the entire mouse. This segmentation resolves the contradiction by providing both protection (when covered) and quick access (when removed).
Solution Approach 2:
The battery cover is extracted as a separate removable component from the main casing. This allows the battery to be accessed by simply removing the cover rather than opening a complex compartment mechanism, thereby improving battery replacement speed while maintaining a relatively simple overall structure.
2Shape
If the battery is disposed inside the mouse casing, then the mouse has a compact design, but the internal space is reduced and battery replacement is difficult
Solution Approach 1:
The battery compartment is divided into removable and fixed portions. The battery cover can be removed to access the battery, while the battery holder remains integrated in the casing. This allows the mouse to maintain a compact external shape while providing easy battery accessibility through the removable cover mechanism.
3Reliability
If the battery is covered by a battery cover on the outside of the battery slot, then the battery is protected, but the battery replacement process becomes more complex
Solution Approach 1:
The battery compartment is segmented into a simple removable cover and a fixed holder. The cover provides protection when closed but can be easily removed for battery replacement. This segmentation achieves both protection and simplicity, avoiding complex multi-step opening mechanisms while maintaining battery security.

AI summary
A mouse device is provided. The mouse device includes a battery module, a casing, and a control circuit. The battery module includes a first connection interface. The casing includes a second connection interface. The control circuit is disposed inside the casing and is electrically connected to the second connection interface. The battery module is detachably mated with the second connection interface through the first connection interface, and the battery module is exposed outside of the casing when being mated with the second connection interface. The control circuit obtains a power supply from the battery module through the second connection interface when the battery module is mated with the second connection interface.
