Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the temperature collecting unit indirectly collects temperature through the busbar or other structures, then the temperature can be monitored, but the temperature collected cannot accurately reflect the battery temperature due to heat interference from the busbar or other structures
Solution Approach 1:
The patent extracts the temperature collecting unit from the busbar structure and positions it directly on the battery surface. The temperature collecting unit includes a support plate with a thermal element that makes direct contact with the battery, separating the temperature sensing function from the electrical connection function performed by the busbar. This extraction eliminates the heat interference from the busbar that was distorting temperature measurements.
Solution Approach 2:
The patent introduces a support plate as an intermediary structure between the temperature collecting unit and the battery. The support plate includes a thermal element that directly contacts the battery surface, and the plate itself acts as a thermal conduction path. This intermediary structure enables direct temperature sensing while isolating the measurement system from the heat-interfering busbar structure.
2Ease of operation
If the thermal element is directly exposed on the support plate, then the temperature can be collected, but the thermal element is vulnerable to damage from external forces
Solution Approach 1:
The patent implements protective structures including rigid stands and elastic stands that surround the thermal element before any damage can occur. The elastic stand specifically provides cushioning protection, absorbing external forces before they can reach the vulnerable thermal element. This beforehand protection ensures the thermal element remains functional while providing mechanical protection.
Solution Approach 2:
The patent uses a composite protective structure combining rigid and elastic materials. The rigid stand provides structural support and protection, while the elastic stand provides shock absorption and cushioning. This composite approach creates a multi-layered protection system that maintains the thermal element's functionality while protecting it from various types of mechanical damage.
