Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If battery cells are densely stacked to increase power output, then the number of battery cells increases, but cooling efficiency deteriorates due to insufficient space for heat dissipation
Solution Approach 1:
The patent transitions from horizontal stacking to vertical stacking of battery cells on a support frame, utilizing the vertical dimension for heat dissipation. Cooling fluids flow through channels in the support frame that contact the vertically arranged cells, enabling effective cooling while maximizing cell density within the available space.
Solution Approach 2:
The support frame acts as an intermediary structure between the battery cells and the cooling system. It provides both mechanical support for the cells and integrated cooling fluid channels that directly contact the cells, facilitating efficient heat transfer without requiring additional separate cooling components.
2Area of stationary object
If traditional horizontal stacking is used, then installation space is sufficient, but cooling efficiency is reduced due to heat accumulation
Solution Approach 1:
The patent reorients battery cell arrangement from horizontal to vertical stacking, utilizing the vertical dimension to improve cooling efficiency. The support frame includes cooling fluid channels that contact the vertically arranged cells, enabling effective heat dissipation while maintaining compact installation space.
3Stability of the object's composition
If wire tension is increased to secure battery modules, then module stability improves, but wire durability decreases due to excessive stress
Solution Approach 1:
The patent employs adjustable wire tensioning mechanisms that allow the wire tension to be dynamically optimized. The tension can be adjusted to provide sufficient module stability while avoiding excessive stress that would compromise wire durability, enabling adaptive adjustment based on operational conditions.
