Information Display Device Battery Replacement Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information display devices with batteries located on the back surface require users to flip the device over for battery replacement, making it difficult to replace the battery while the device is installed.
Innovation Solution
The information display device features a battery insertion portion on the bottom side surface, allowing the battery to be detached and replaced in the same plane as the screen, with a battery locking mechanism that slides outward to unlock and a waterproof design to prevent water ingress during replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the battery is located on the back surface of the device, then the device structure is simplified, but the battery cannot be replaced while the device is installed
Solution Approach 1:
The battery access is moved from the back surface (Z-axis direction) to the bottom side surface, allowing battery replacement in the same plane as the screen without requiring the device to be flipped or turned over
2Shape
If the battery is enclosed in an exterior cover, then the device has a unified appearance, but the cover must be removed for battery replacement
Solution Approach 1:
The battery compartment is extracted from the interior of the device and positioned on the bottom side surface, allowing the battery to be accessed and replaced without removing any exterior covers or panels
3Ease of operation
If the battery insertion portion is on the bottom side surface, then battery replacement is enabled in installed state, but waterproofing becomes more difficult
Solution Approach 1:
A waterproof film is used to seal the battery insertion portion on the bottom side surface, preventing water ingress while allowing the battery compartment to remain accessible for replacement
