Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a fixed suspension structure is used in the crawler chassis, then the device complexity is reduced, but the adaptability to complex terrain deteriorates and the stability decreases
Solution Approach 1:
The patent applies the dynamics principle by transforming the fixed suspension structure into a dynamic, adjustable system. The suspension structure can now change its configuration through pitch and roll angle adjustments, allowing it to adapt to varying terrain conditions while maintaining manageable complexity through systematic control mechanisms.
Solution Approach 2:
The patent implements parameter changes by enabling the suspension structure to modify its geometric parameters (pitch and roll angles) in response to terrain variations. This allows the same suspension system to optimize its performance across different terrain types without requiring multiple fixed configurations.
2Device complexity
If the suspension structure cannot adjust pitch and roll angles, then the device complexity is reduced, but the obstacle crossing ability deteriorates
Solution Approach 1:
The patent transforms the static suspension system into a dynamic one capable of real-time angle adjustments. This enables the crawler chassis to actively respond to obstacles by modifying its suspension geometry, significantly improving obstacle crossing capability while maintaining reasonable system complexity through integrated control.
Solution Approach 2:
The patent applies preliminary action by enabling the suspension system to proactively adjust its pitch and roll angles in anticipation of or response to upcoming terrain features. This allows the crawler to optimize its configuration before encountering obstacles, enhancing crossing ability while managing complexity through predictive control strategies.
3Manufacturing precision
If a fixed suspension structure is used, then the manufacturing precision requirements are reduced, but the operational stability on complex terrain deteriorates
Solution Approach 1:
The patent resolves this contradiction by implementing a dynamic suspension system that can adapt its configuration during operation. This dynamic capability compensates for variations in manufacturing precision, allowing the system to maintain operational stability across different terrain conditions without requiring extremely tight manufacturing tolerances.
Solution Approach 2:
The patent applies parameter changes by enabling the suspension structure to modify its operational parameters (angles and positions) in real-time. This flexibility allows the system to compensate for manufacturing variations and maintain stable operation on complex terrain, reducing the stringency of manufacturing precision requirements.
4Adaptability or versatility
If the suspension structure is made adjustable for terrain adaptation, then the adaptability improves, but the device complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the suspension adjustment system into modular components that can be independently controlled. This modular approach enables terrain adaptability through coordinated adjustments of multiple segments while managing overall system complexity through distributed control architecture.
Solution Approach 2:
The patent implements universality by designing the suspension adjustment system to perform multiple functions simultaneously - pitch adjustment, roll adjustment, obstacle crossing, and terrain adaptation. This multi-functionality reduces the need for separate specialized mechanisms, thereby managing complexity while enhancing adaptability.
