Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge is to enlarge the decorative member of an electronic device to accommodate more functional devices while maintaining a proper layout and battery capacity.
Innovation Solution
The electronic device design includes a battery cover with a hole, a battery module, a decorative member with through holes, and functional devices arranged to overlap orthographic projections, allowing for increased space utilization without affecting battery capacity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the decorative member is enlarged to accommodate more functional devices, then the functionality and appearance of the electronic device are improved, but the internal space for the battery and main board is reduced
Solution Approach 1:
The patent utilizes the thickness direction (Z-axis) of the battery cover to arrange functional devices. By projecting the battery protection circuit board, decorative member, and functional devices along the thickness direction to form overlapping orthographic projections, the design transforms a two-dimensional layout problem into a three-dimensional space utilization solution, effectively increasing functionality without reducing internal space.
2Adaptability or versatility
If more functional devices are arranged in the region corresponding to the main board, then the functionality is improved, but the density of functional devices increases and layout becomes complex
Solution Approach 1:
The patent distributes functional devices across two different regions: one region corresponding to the main board and another region corresponding to the battery protection circuit board. By utilizing the thickness direction to create overlapping projections, the design spreads functional devices across multiple spatial dimensions, reducing density in any single region and simplifying the overall layout while maintaining enhanced functionality.

AI summary
An electronic device includes: a battery cover with a hole, a battery module, a battery protection circuit board and a first functional device. The battery module is arranged on an inner side of the battery cover and including a battery and a battery protection circuit board arranged facing the hole. The decorative member is arranged on the battery cover and including a first decorative portion and a second decorative portion. The battery protection circuit board is projected to form a first orthographic projection. The first decorative portion is projected to form a second orthographic projection. The first functional device is located on a side of the battery protection circuit board facing the first decorative portion and arranged corresponding to the first through hole.
