Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If rigid connection is used to connect test benches to frame structure, then structural stability is improved, but damage to frame structure occurs due to huge acting force
Solution Approach 1:
The patent replaces rigid connections with flexible spherical hinge connections between test benches and frame structure. The spherical hinges allow relative motion and displacement while maintaining connection, preventing the transmission of huge acting forces that would damage the frame structure during road simulation testing.
Solution Approach 2:
The patent changes the connection parameter from rigid (fixed distance and orientation) to flexible (variable distance and orientation through spherical hinges). This parameter change allows the system to adapt to dynamic loading conditions during road simulation, preventing structural damage while maintaining testing functionality.
2Stability of the object's composition
If rigid connection is used, then connection stability is improved, but relative displacement cannot be achieved causing shear force and damage
Solution Approach 1:
Spherical hinges provide flexible connections that can accommodate relative displacement between test benches and frame structure. This flexibility prevents the accumulation of shear forces that would occur with rigid connections, eliminating the harmful effect while maintaining connection stability.
Solution Approach 2:
The patent introduces dynamic capability to the connection system through spherical hinges, allowing the connection to adapt its configuration in response to dynamic loading and displacement during road simulation. This dynamic adaptation prevents shear force buildup while maintaining stable connection.
3Device complexity
If only vertical motion is enabled, then test bench simplicity is improved, but theoretical relative displacement on horizontal plane cannot be achieved
Solution Approach 1:
Spherical hinges provide passive flexibility that enables relative displacement in multiple directions without requiring complex active control mechanisms. This achieves the desired adaptability while maintaining relatively simple test bench structure.
Solution Approach 2:
The spherical hinge acts as an intermediary element between the vertically moving test bench and the frame structure, enabling horizontal relative displacement through its rotational degrees of freedom while the test bench itself maintains simple vertical motion capability.
4Adaptability or versatility
If spherical hinges and sliding plates are added, then relative displacement compensation is improved, but device complexity increases
Solution Approach 1:
The spherical hinge provides inherent flexibility and displacement compensation capability through its spherical geometry and rotational degrees of freedom. This passive mechanical flexibility achieves adaptability without requiring complex active control systems or multiple components.
Solution Approach 2:
The spherical hinge and sliding plate combination introduces dynamic adaptability to the test bench system, allowing automatic compensation for relative displacement through mechanical degrees of freedom rather than complex control algorithms or additional actuators.
