Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If traditional abutment benches are used for chassis repair, then the structure is simple and easy to manufacture, but the stability on ground is poor causing excessive oscillations during measurement
Solution Approach 1:
The abutment bench is divided into multiple independent stabilization assemblies, each with its own stabilization body and adjustment mechanism. These modular units are distributed across the horizontal flatbed to provide localized stability without requiring a completely redesigned monolithic structure.
Solution Approach 2:
The stabilization assemblies are positioned and adjusted before the wheel alignment measurement process begins. The stabilization bodies are preliminarily set to contact the ground and prevent oscillations, ensuring the bench is stable before measurements are taken.
2Measurement precision
If measuring operations are performed on traditional abutment benches, then wheel alignment adjustment is possible, but excessive oscillations interfere with measurement precision
Solution Approach 1:
The stabilization function is segmented into separate assemblies distributed across the bench, allowing each to independently dampen oscillations in its local area without interfering with the measurement process elsewhere.
Solution Approach 2:
The stabilization bodies act as intermediary elements between the horizontal flatbed and the ground. They transfer and absorb oscillation energy, preventing these vibrations from reaching the measuring system and interfering with precise measurements.
3Manufacturing precision
If coarse adjustment mechanisms are used, then the device is simple to operate, but only rather coarse adjustments of geometric angles are achieved
Solution Approach 1:
The stabilization assemblies incorporate adjustable elements that can be dynamically positioned and locked. This allows the operator to easily adjust the stabilization level according to specific measurement needs, providing both ease of operation and precise adjustment capability.
Solution Approach 2:
The system allows changing of stabilization parameters (such as contact pressure, position, and engagement level) to match different measurement requirements. This enables precise adjustments of geometric angles while maintaining simple operational procedures through standardized adjustment mechanisms.
