Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The long charging path in electronic devices leads to current loss, increased heat, reduced charging efficiency, and safety risks such as fires and explosions during rapid charging.
Innovation Solution
The electronic device design features a short charging path by arranging the battery protection board between the first and second boards, with flexible circuit boards connecting them in a configuration that reduces the current transmission path length, allowing for efficient charging and discharging while minimizing heat generation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the charging path is arranged through multiple boards and flexible circuit boards, then the device structure is more modular and easier to manufacture, but the current transmission path becomes long causing current loss and heat generation
Solution Approach 1:
The patent merges the battery protection board with either the first board or second board to form an integrated structure. This integration eliminates the need for separate flexible circuit boards for connecting the protection board, thereby shortening the current transmission path and reducing current loss while maintaining modular manufacturing benefits through the integrated design
2Ease of manufacture
If the charging path is arranged through multiple boards and flexible circuit boards, then the device structure is more modular, but the heat generation during charging increases
Solution Approach 1:
The patent merges the battery protection board with either the first board or second board to form an integrated structure. This integration eliminates the need for separate flexible circuit boards for connecting the protection board, thereby shortening the current transmission path and reducing heat generation during charging while maintaining modular manufacturing benefits through the integrated design
3Speed
If the charging path is long with large current flow, then rapid charging capability is achieved, but safety risks such as fires and explosions increase
Solution Approach 1:
The patent merges the battery protection board with either the first board or second board to form an integrated structure. This integration shortens the current transmission path, reducing current loss and heat generation, thereby maintaining rapid charging capability while improving safety by reducing the risks of fires and explosions
Solution Approach 2:
The integrated board structure acts as an intermediary that optimizes the current transmission path between the power interface and battery. By providing a direct, integrated connection rather than a multi-board path, it reduces resistance and heat generation, thereby maintaining safe operating temperatures during rapid charging
