Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If air is used as heat transfer medium to cool or heat battery, then battery temperature can be regulated, but heat transfer efficiency decreases and peripheral members are heated or cooled causing energy loss
Solution Approach 1:
The patent introduces a thermally conductive member as an intermediary between the heating/cooling device and the battery. This mediator directly contacts the battery to transfer heat efficiently while being thermally insulated from peripheral members, thus preventing energy loss to surrounding components while maintaining effective battery temperature regulation.
2Temperature
If air is blown towards battery for temperature regulation, then battery can be heated or cooled, but temperature distribution becomes uneven causing load concentration on specific cells
Solution Approach 1:
The patent applies local quality by having the thermally conductive member contact multiple battery cells simultaneously at different locations. This ensures that heat is distributed uniformly across all contacted cells rather than concentrating on specific areas, preventing load concentration and potential cell failure while achieving even temperature distribution.
3Temperature
If heater is used to heat battery, then battery temperature can be maintained in cold conditions, but temperature difference occurs between portions near and far from heater
Solution Approach 1:
The patent segments the heating function by placing multiple heating devices at different locations on the battery rather than using a single heater. This segmentation allows heat to be applied at multiple points simultaneously, eliminating temperature differences between near and far portions while improving overall heating efficiency and reducing energy loss.
