Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices with embedded batteries require complex procedures for battery replacement, making it difficult for users to easily exchange batteries, which is undesirable for maintainability and user convenience.
Innovation Solution
An electronic apparatus design featuring a chassis with a detachable cover member and a latch mechanism, including a spring-biased latch member and inclined wall portions, allows for easy battery removal and installation without tools.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of stationary object
If the battery is embedded in the chassis to achieve a thin chassis, then the chassis thickness is reduced, but the battery replacement becomes complicated and difficult for users
Solution Approach 1:
The battery assembly is segmented from the chassis through a detachable cover member design. The cover member can be separately removed to access the battery, while the battery itself remains integrated within the chassis structure. This segmentation allows the chassis to maintain a thin profile while enabling easy battery replacement through cover removal alone, without requiring disassembly of the entire chassis or complex tools.
2Stability of the object's composition
If the battery is fixed with screw threads or pressure sensitive adhesive to secure it in place, then the battery is firmly held, but the battery replacement requires complicated procedures and various tools
Solution Approach 1:
The fixation mechanism (screw threads or pressure sensitive adhesive) is extracted from the battery itself and transferred to the cover member. The battery is designed with a simple bottom surface that can be easily accessed, while the cover member incorporates the fixation elements. This allows the battery to be firmly held when the cover is attached, but enables simple replacement by merely removing the cover without dealing with screws or adhesives directly.
3Ease of operation
If the battery is easily accessible for replacement, then user convenience is improved, but the chassis structure becomes more complex
Solution Approach 1:
The battery access function is merged with the cover member, which is an existing structural component of the chassis. The cover member serves dual purposes: protecting the battery when attached and providing access to the battery when removed. This merging avoids adding separate access mechanisms or complex disassembly structures, maintaining chassis simplicity while enabling easy battery replacement.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design secures a thin chassis while enabling simple and tool-free battery replacement, reducing user effort and maintaining device thickness.
Implementation Method 1
a spring member provided between the chassis member and the battery and configured to bias the battery so that the battery rises up from an inner surface of the chassis member
Implementation Method 2
a latch member supported on the chassis member in such a manner as to be movable between a locked position where the latch member holds down the locked part and an unlocked position where the latch member retracts from the locked part

AI summary
An electronic apparatus includes: a chassis member having an opening surface; a cover member including a plate portion, and an inclined wall portion provided in a standing manner from an edge portion of the plate portion and inclined in a direction separating from the plate portion toward a standing direction of the inclined wall portion, the cover member being configured to open and close at least part of the opening surface; a battery detachably supported on an inner surface side of the chassis member and including a locked part on a first lateral surface facing the inclined wall portion; a latch member supported on the chassis member in such a manner as to be movable between a locked position where the latch member holds down the locked part and an unlocked position where the latch member retracts from the locked part; and a spring member.
