Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If the housing is provided with a relatively low coefficient of heat conductivity, then heat dissipation equilibrium is maintained, but local battery temperature becomes relatively high
Solution Approach 1:
The patent introduces a thermally conductive connector as an intermediary component between the battery and housing. This connector has high thermal conductivity that facilitates heat transfer from the battery to the housing, solving the problem of high local battery temperature while maintaining the housing's low overall heat conductivity for thermal equilibrium.
Solution Approach 2:
The patent applies local quality by creating a localized high thermal conductivity path only where needed (between battery and housing via the connector), while the rest of the housing maintains its low thermal conductivity properties. This targeted approach allows heat dissipation from the battery without compromising the overall thermal management of the device.
2Reliability
If heat dissipation components are optimized for equilibrium, then overall thermal balance is improved, but heat transfer efficiency to housing is insufficient
Solution Approach 1:
The thermally conductive connector serves as a mediator that bridges the gap between heat generation at the battery and heat dissipation at the housing. It enhances the heat transfer efficiency locally without disrupting the overall thermal equilibrium of the device.
Solution Approach 2:
The connector may be made of composite materials or materials with specific thermal properties that optimize heat transfer from the battery to the housing, combining the benefits of high thermal conductivity with mechanical attachment functionality.
