Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a large number of storage batteries are installed in the vehicle, then the energy storage capacity is improved, but the vehicle body space is insufficient
Solution Approach 1:
The battery system is divided into multiple battery modules, each with its own end plates and coupling bands. This segmentation allows for compact arrangement and efficient space utilization within the vehicle body, enabling installation of more batteries without increasing overall space occupation.
Solution Approach 2:
Multiple battery modules are stacked in the stacking direction with end plates and coupling bands nesting together. The coupling bands pass through openings in end plates and are secured with pressing devices, creating a nested structure that maximizes space efficiency while accommodating numerous batteries.
2Quantity of substance
If storage batteries are stacked in the stacking direction, then the energy density is improved, but the alignment precision deteriorates due to dimensional variations
Solution Approach 1:
End plates are introduced as intermediary components between stacked batteries. These end plates provide standardized contact surfaces that compensate for dimensional variations in individual batteries, ensuring consistent alignment throughout the stack regardless of manufacturing tolerances.
Solution Approach 2:
The pressing device adjusts the pressing force parameter to compensate for dimensional variations. By applying controlled force through the coupling band and pressing device mechanism, the system maintains proper alignment and contact pressure across all batteries in the stack, overcoming variations in battery dimensions.
3Reliability
If a robust fixation system is implemented, then the reliability is improved, but the device complexity increases
Solution Approach 1:
The fixation function is merged into the coupling band structure. The coupling band not only connects end plates but also incorporates the pressing device mechanism, integrating multiple functions (connection, alignment, and fixation) into a single component system, thereby reducing overall complexity while maintaining reliability.
Solution Approach 2:
The end plates serve multiple functions: providing structural support, enabling alignment through standardized surfaces, facilitating connection via coupling bands, and working with pressing devices for secure fixation. This multi-functionality reduces the need for separate dedicated fixation components, simplifying the overall system while enhancing reliability.
