Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing fixation methods are used to securely attach the steering cylinder, then reliable connection is achieved, but device complexity increases due to comprehensive design adjustments and additional parts
Solution Approach 1:
The coupling projection and coupling recess are integrated directly into the steering cylinder and axle part respectively, merging the fixation function into the main components. This eliminates the need for separate fixation parts and comprehensive design adjustments, reducing device complexity while maintaining connection reliability through the interference fit mechanism
Solution Approach 2:
The coupling projection design serves multiple functions: it provides structural attachment, enables interference fit for secure connection, and allows for simplified assembly. This multi-functionality reduces the need for additional dedicated fixation parts, thereby reducing device complexity while maintaining reliable attachment
2Reliability
If existing fixation methods are used to securely attach the steering cylinder, then reliable connection is achieved, but loss of time increases due to increased assembly time
Solution Approach 1:
The coupling projection and coupling recess are pre-formed as integral parts of the steering cylinder and axle part respectively. This preliminary preparation eliminates the need for on-site assembly adjustments and additional fixation operations, significantly reducing assembly time while ensuring reliable connection through the pre-designed interference fit
Solution Approach 2:
By merging the fixation function into the main components through integrated coupling elements, the assembly process is simplified to a single insertion operation. This eliminates multiple assembly steps required by existing methods, reducing assembly time while maintaining connection reliability
3Reliability
If existing fixation methods are used to securely attach the steering cylinder, then reliable connection is achieved, but adaptability decreases due to limited compatibility between steering cylinder and surrounding part
Solution Approach 1:
The coupling projection design with its specific geometric features (rounded cross-section, interference fit capability) serves as a universal interface that can be adapted to various axle part configurations. This universal design approach enables compatibility across different vehicle models and steering system variants while maintaining reliable connection through the interference fit mechanism
Solution Approach 2:
The fixation function is segmented into a standardized coupling projection that can be independently designed and manufactured. This segmentation allows the coupling projection to be optimized for reliability while the surrounding parts can be varied for different applications, thereby improving adaptability and compatibility
