Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If bearing blocks are used as frame units with additional support elements, then stability is improved, but device complexity and assembly work increase
Solution Approach 1:
The patent integrates the support function directly into the bearing block structure by forming a transverse area that is integral with either the outer or inner part. This merging eliminates the need for separate support elements and their corresponding fastening operations, thereby reducing device complexity while maintaining stability.
Solution Approach 2:
The bearing block is divided into two functional parts: the main bearing block (outer and inner parts) and the integrally formed transverse area. This segmentation allows the transverse area to specifically handle stabilization functions while the main body handles bearing functions, optimizing the overall structure without requiring additional components.
2Reliability
If bearing blocks are stabilized by additional support elements, then reliability is improved, but assembly work and time increase
Solution Approach 1:
The support function is merged into the bearing block by forming the transverse area as an integral part during manufacturing. This eliminates the need for separate assembly steps to attach support elements, significantly reducing assembly time and labor while ensuring reliable structural integration.
Solution Approach 2:
The transverse area is formed integrally with the bearing block during the manufacturing process, performing the stabilization function in advance before the assembly stage. This preliminary action eliminates the need for additional assembly operations, reducing both time and complexity.
3Strength
If bearing blocks are made oversized, then strength is improved, but weight and material usage increase
Solution Approach 1:
The transverse area is formed with optimized local geometry that provides sufficient strength for stabilization without requiring the entire bearing block to be oversized. The integral formation allows material to be distributed efficiently where needed, maintaining strength while reducing overall weight compared to traditional oversized bearing blocks.
4Ease of manufacture
If bearing blocks cannot be adapted to local stress peaks, then manufacturing is simplified, but reliability decreases
Solution Approach 1:
The transverse area is designed with specific geometric characteristics that allow it to adapt to local stress conditions. The integral formation enables the structure to naturally distribute and accommodate stress peaks without requiring complex manufacturing processes, maintaining ease of manufacture while improving reliability.
