Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the vehicle body structure size is greatly reduced, then the vehicle size is reduced, but the collision strength of the vehicle body structure is reduced
Solution Approach 1:
The vehicle body structure is divided into multiple independent components including rear longitudinal beams, rear wheel covers, supporting rods, and connection structures. Each component is optimized independently to contribute to overall collision strength while maintaining compact dimensions. The segmented design allows force to be distributed across multiple elements rather than concentrated in a single large structure.
Solution Approach 2:
The patent employs composite material construction in the vehicle body structure, combining materials with different mechanical properties to achieve high strength-to-weight ratio. The rear longitudinal beams, wheel covers, and supporting rods utilize composite materials that provide enhanced collision resistance without increasing overall vehicle size, resolving the contradiction between compact dimensions and structural strength.
2Volume of stationary object
If the rear part structure size is reduced, then the vehicle size is reduced, but the force transmission capability is weakened
Solution Approach 1:
The force transmission system in the rear structure utilizes three-dimensional spatial arrangement of components. The rear wheel covers are positioned to intercept forces from multiple directions, while supporting rods are oriented at optimal angles to transmit forces efficiently to the rear longitudinal beams. This dimensional optimization enables effective force transmission within a compact rear structure volume.
Solution Approach 2:
Connection structures serve as intermediaries between the rear wheel covers, supporting rods, and rear longitudinal beams. These intermediary elements efficiently transfer forces between components, ensuring that the compact rear structure maintains strong force transmission capability through optimized force pathways rather than relying on large structural dimensions.
