Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If conventional lead acid batteries are used for heavy duty jump starters, then the power output is sufficient for jump starting heavy equipment, but the weight becomes hundreds of pounds and the device requires forklift for movement
Solution Approach 1:
The patent changes the battery chemistry from conventional lead acid to lithium-ion technology, fundamentally altering the physical and chemical parameters of the energy storage system. This parameter change enables the same power output capability with dramatically reduced weight and volume, allowing the jump starter to provide heavy duty performance while remaining portable and manageable without forklift equipment
2Power
If conventional heavy duty jump starters are designed for maximum power output, then they can jump start heavy equipment, but their size becomes large and they are not portable
Solution Approach 1:
The patent changes the battery chemistry from conventional lead acid to lithium-ion technology, fundamentally altering the physical and chemical parameters of the energy storage system. This parameter change enables the same power output capability with dramatically reduced weight and volume, allowing the jump starter to provide heavy duty performance while remaining portable and manageable without forklift equipment
Solution Approach 2:
The patent employs lithium-ion battery cells with advanced composite materials including aluminum current collectors, copper foils, and specialized electrolytes. These composite materials provide high energy density and excellent electrical conductivity in a compact form factor, enabling the device to deliver heavy duty power output while maintaining a portable size that does not require forklift handling
3Power
If the frame is made of standard conductive material, then the structure is adequate, but the power conduction efficiency from battery to output is insufficient
Solution Approach 1:
The patent merges the frame structure with the battery assembly by integrating the aluminum current collectors and copper foils directly into the structural framework. This consolidation eliminates separate conduction pathways and reduces interface resistance, allowing the frame to simultaneously provide mechanical support and high-efficiency electrical conduction from the battery cells to the output terminals

AI summary
A rechargeable battery assembly includes a rechargeable battery having a positive terminal and a negative terminal, and a rigid electrically conductive frame electrically connected to at least one of the positive terminal or the negative terminal of the rechargeable battery. The rigid electrically conductive frame is bent along multiple axes and includes a plurality of conductive frame members that are mechanically coupled together. The rigid electrically conductive frame surrounds the rechargeable battery on at least five sides, thereby providing structural stability to the rechargeable battery assembly during storage and use.
