Rotatable Anchoring Members for Secure Battery Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional portable electronic devices fail to securely position batteries within their housings, leading to potential electrical disconnection and unstable power supply due to impact-induced misalignment.
Innovation Solution
A portable electronic device design featuring a main casing with a battery-receiving groove flanked by resilient abutting tongues and a cover with rotatable anchoring members that switch between releasing and clamping states to securely position the battery, ensuring electrical connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the battery is received in the battery-receiving groove without anchoring members, then the device structure is simple, but the battery cannot be positioned effectively leading to electrical disconnection under impact
Solution Approach 1:
The anchoring members are designed to be rotatable rather than fixed, allowing them to dynamically adjust between a releasing state (when cover is removed) and a clamping state (when cover is installed). This dynamic mechanism provides reliable battery positioning only when needed, maintaining simplicity when the battery compartment is accessed.
Solution Approach 2:
The housing is divided into functional segments: the main casing with battery-receiving groove, the cover for access, and the anchoring members for securing. This segmentation allows each component to perform its specific function independently, with the anchoring members providing positioning stability without requiring the entire housing structure to be complex.
2Reliability
If anchoring members are added to secure the battery, then electrical connection stability is improved, but the device structure becomes more complex
Solution Approach 1:
The anchoring members use a rotatable design that switches between clamping and releasing states based on cover installation, providing electrical connection stability only when the device is in normal operation mode, while maintaining structural simplicity during maintenance or battery replacement.
Solution Approach 2:
The anchoring members are automatically actuated by the installation or removal of the cover itself, which engages or disengages the anchoring members without requiring separate control mechanisms. This self-service approach ensures reliable electrical connection while minimizing additional structural complexity.
3Reliability
If the abutting tongues are always pressed against the battery, then positioning stability is improved, but the battery cannot be easily removed or installed
Solution Approach 1:
The anchoring members provide continuous clamping force on the battery when the cover is installed, ensuring stable positioning during normal operation. When the cover is removed, the anchoring members automatically release, allowing easy battery installation and removal without requiring tools or complex operations.
Solution Approach 2:
The design anticipates the need for both secure positioning and easy removal by using the cover installation itself as the trigger to switch the anchoring state. The preliminary action of installing the cover automatically engages the anchoring members, while removal automatically disengages them, eliminating the need for separate locking or unlocking operations.

AI summary
A portable electronic device includes a main casing having a battery-receiving groove for receiving a battery therein, and two aligned resilient abutting tongues flanking the battery-receiving groove. A cover is mounted removably on the main casing for covering the battery-receiving groove. Two anchoring members are mounted rotatably on the cover, extends into the main casing, and is operable so as to switch between a releasing state, where the abutting tongues are spaced respectively apart from the battery, and a clamping state, where the abutting tongues are pressed respectively against the battery.
