Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional battery packs require disassembly and additional cable connections for firmware updates, making it difficult for users to perform updates efficiently and conveniently, often necessitating professional assistance.
Innovation Solution
A battery pack design featuring a memory slot unit integrated into the pack case, allowing for firmware updates without disassembly, using a rotatable slot cover to expose the insert slot for a memory unit, such as an SD card, facilitating easier access for users.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If firmware update is performed using conventional method with separate cable connection, then update reliability is ensured, but operation complexity increases and user convenience deteriorates
Solution Approach 1:
The patent combines the memory unit and communication function into an integrated memory slot unit that is built into the battery pack. This merging eliminates the need for separate cable connections and external communication devices, allowing users to perform firmware updates by simply inserting a memory card into the integrated slot, thereby simplifying the update process while maintaining reliable communication.
Solution Approach 2:
The battery pack is designed with self-service capability for firmware updates through the integrated memory slot unit. Users can independently perform updates by inserting a memory card without requiring professional assistance or complex cable connections. The system automatically recognizes the memory unit and facilitates the update process, enabling end-users to maintain their own battery packs.
2Productivity
If pack case is disassembled for firmware update, then access to BMS unit is achieved, but time consumption increases and productivity decreases
Solution Approach 1:
The memory slot unit is pre-integrated into the battery pack structure during manufacturing, with the communication interface and memory card slot permanently installed. This preliminary integration eliminates the need for disassembly operations during firmware updates. Users can directly insert the memory card into the pre-positioned slot, significantly reducing update preparation time and improving overall update efficiency.
3Ease of operation
If separate cable connection is used for firmware update, then communication reliability is maintained, but ease of operation deteriorates
Solution Approach 1:
The communication interface is merged with the memory slot unit and built into the battery pack structure. This integration ensures stable electrical connections through fixed contacts within the slot, eliminating the reliability issues associated with external cable connections. The integrated design maintains reliable communication between the BMS unit and memory card while simultaneously improving ease of operation through simple card insertion.
