Battery Latch Mechanism for Tool-Free Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices with battery cases face challenges in rapid attachment and detachment without tools, especially in limited spaces, due to the use of screws which require a screwdriver and are inconvenient.
Innovation Solution
A battery accommodating module with a latch member and crisscross switch that allows for tool-free attachment and detachment, utilizing pivot holes, restraining portions, and positioning features to securely fix and release the battery case within the electronic device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If screws are used to fix the battery case, then the battery case can be securely fixed in the casing, but the battery case cannot be attached or detached rapidly without tools
Solution Approach 1:
The patent replaces the traditional screw-based mechanical fastening system with a latch member mechanism that uses elastic deformation and geometric interlocking. The latch member with elastic portions can be operated manually to switch between locked and unlocked states, eliminating the need for screwdrivers while maintaining secure fixation when engaged.
Solution Approach 2:
The latch member is designed with elastic portions that can dynamically change shape between locked and unlocked configurations. The elastic deformation allows the latch to flex during attachment and detachment operations, enabling rapid tool-free operation while maintaining reliable engagement when locked in position.
2Device complexity
If a traditional battery case structure is used, then the structure is simple, but the attachment and detachment process requires tools and is inconvenient
Solution Approach 1:
The latch member is nested within the battery case structure, with the elastic portions integrated into the case body. This nested design allows the fastening mechanism to be incorporated without significantly increasing the overall structural complexity, while still enabling tool-free operation through manual actuation of the latch member.
Solution Approach 2:
The elastic portions of the latch member automatically return to their original shape after deformation, providing self-resetting functionality. The latch mechanism is designed to be operated manually without external tools, and the elastic recovery force automatically maintains the locked state, making the system self-servicing.

AI summary
A battery accommodating module is used for accommodating a battery. The battery accommodating module includes a battery case and a latch member. The battery case has an accommodating space and a side of the battery case has two pivot holes and at least one first restraining portion. The latch member has two pivot portions and at least one second restraining portion, wherein the pivot portions are pivotally connected to the pivot holes, such that the latch member can rotate with respect to the battery case between a lock position and an unlock position. When the latch member is located at the unlock position, the first restraining portion keeps the second restraining portion at a first side of the first restraining portion. When the latch member is located at the lock position, the first restraining portion keeps the second restraining portion at a second side of the first restraining portion.
