Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If a receiving device for energy storage cells is installed in the motor vehicle, then electrical energy can be supplied to consumers, but the receiving device occupies significant space in the vehicle
Solution Approach 1:
The receiving device is divided into multiple receiving parts (first receiving part, second receiving part) that can be arranged in different locations within the vehicle's subfloor. This segmentation allows the energy storage system to be distributed across available space rather than concentrated in one location, reducing the impact on any single area while maintaining total energy storage capacity.
Solution Approach 2:
The receiving device is arranged in the subfloor area (horizontal dimension) rather than occupying vertical space that would reduce passenger or cargo volume. By utilizing the subfloor space and connecting receiving parts through connection bars, the design transforms the spatial problem from a vertical constraint to a horizontal arrangement, effectively using otherwise underutilized vehicle space.
2Adaptability or versatility
If the receiving device is divided into separate receiving parts, then arrangement flexibility is improved, but the structural complexity increases
Solution Approach 1:
Multiple receiving parts are connected through connection bars that integrate electrical line connections and temperature-control fluid line connections into single structural elements. This merging approach reduces the number of separate connection points and simplifies the overall system architecture while maintaining the flexibility of having distributed receiving parts.
Solution Approach 2:
The connection bars serve multiple functions simultaneously: they provide mechanical support between receiving parts, conduct electrical energy through line connections, and transport temperature-control fluids. This multi-functionality reduces the need for separate dedicated components for each function, thereby reducing overall structural complexity despite the distributed arrangement of receiving parts.
