Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a heating wire is embedded in the heat transport body, then heating efficiency is improved, but the risk of contact between heating wire and battery housing increases
Solution Approach 1:
The patent introduces a base plate as an intermediary component between the heating wire and the battery housing. The heating wire is embedded in the base plate, which then contacts the battery housing. This intermediary structure allows heat to be transferred from the heating wire to the battery while preventing direct contact between the heating wire and the battery, thus eliminating the harmful contact risk while maintaining heating efficiency.
2Device complexity
If a multifunctional temperature control device is used for both heating and cooling, then device complexity is reduced, but the installation space requirement increases
Solution Approach 1:
The patent designs a temperature control device that can serve both heating and cooling functions through a single integrated structure. The heat transport body with embedded heating wire can operate in heating mode by activating the heating wire, and in cooling mode by utilizing the heat transport body as a heat sink. This multi-functional design reduces the need for separate heating and cooling devices, thereby reducing overall device complexity while the base plate design helps manage the installation space requirement.
3Productivity
If the heating wire is arranged on the upper side of the base plate, then heating performance is improved, but the risk of overlap with battery contact area increases
Solution Approach 1:
The patent applies local quality by creating distinct functional zones on the base plate. The upper side of the base plate is divided into different areas: one area for battery contact (with a footprint) and another area for heating wire arrangement. This spatial differentiation ensures that the heating wire is positioned in a location optimized for heating performance while preventing overlap with the battery contact area, thus eliminating the harmful overlap effect while maintaining heating effectiveness.
