Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If conventional thermal management devices are used, then heat exchange function is provided, but device volume is large and integration space is insufficient
Solution Approach 1:
The tangential turbomachine is nested within the collector box volute structure, with the rotor positioned inside the volute chamber. This nesting arrangement allows the cooling module to achieve compact dimensions while maintaining both cooling function and air flow generation capability, resolving the contradiction between reduced volume and sustained heat exchange efficiency.
Solution Approach 2:
The invention merges the air flow generation function (previously requiring separate fans) with the heat exchanger assembly by integrating the tangential turbomachine directly into the collector box. This consolidation eliminates additional components and reduces overall module volume while preserving heat exchange performance through the volute's optimized air flow path.
2Volume of moving object
If cooling module is compacted to save space, then integration becomes easier, but air flow efficiency may be compromised
Solution Approach 1:
The volute structure employs curved, spiral geometry to guide air flow efficiently through the compact collector box. This curved path design maximizes air flow velocity and distribution across the heat exchanger surfaces within limited space, maintaining high air flow rates despite the compacted module volume.
Solution Approach 2:
The tangential turbomachine utilizes pneumatic principles to generate controlled air flow through its rotating blades, creating a vortex pattern that efficiently moves air through the volute and across the heat exchanger. This pneumatic mechanism enables effective air flow generation within the compact structure without requiring additional space for separate air moving devices.
3Quantity of substance
If batteries occupy large space to extend range, then electric vehicle range is improved, but space for thermal management devices is reduced
Solution Approach 1:
The cooling module is designed to be positioned in the vertical dimension between the upper and lower floors of the modular platform, rather than occupying horizontal space that would reduce battery capacity. This vertical arrangement allows thermal management functionality to be integrated without compromising battery volume or electric vehicle range.
Solution Approach 2:
The modular platform architecture segments the vehicle structure into upper and lower floors with the cooling module integrated in the intermediate space. This segmentation allows independent optimization of battery volume in the lower section and thermal management functionality in the vertical interval, resolving the space conflict between battery capacity and cooling device integration.
