Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional supporting device structure is used, then the device is simple in structure, but the pivotal movement cannot be adjusted or limited
Solution Approach 1:
The patent implements dynamic adjustability by allowing the shank to pivot relative to the housing through spring biasing members that enable controlled movement. The system transitions from a fixed structure to one where the pivotal angle can be dynamically adjusted and locked at different positions, resolving the contradiction between structural simplicity and movement adjustability.
Solution Approach 2:
The supporting device is segmented into distinct functional components: housing, shank, spring biasing members, and limiting structures. This segmentation allows each component to perform its specific function independently while contributing to the overall adjustability, managing complexity through modular design.
2Adaptability or versatility
If an adjustable pivotal structure is added, then the adaptability of pivotal movement is improved, but the device complexity increases
Solution Approach 1:
The spring biasing members automatically engage with the limiting structures to lock the shank at desired pivotal positions without requiring external control mechanisms. This self-servicing feature provides controllability while minimizing the complexity of additional control systems.
Solution Approach 2:
The patent changes the physical parameters of the system by introducing spring force and geometric constraints that define specific pivotal angles. These parameter changes enable controlled adjustability through physical laws rather than complex mechanical controls.
3Ease of operation
If spring biasing members are used for controlled pivoting, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The patent replaces complex mechanical control systems with spring-based elastic mechanisms. The spring biasing members use elastic deformation and force to control pivotal movement, substituting intricate mechanical linkages with simpler elastic elements that provide intuitive ease of operation.
Solution Approach 2:
The spring biasing members act as intermediaries between the shank and housing, mediating the pivotal movement through elastic force. This intermediary mechanism simplifies the interaction between components while providing controlled adjustability, reducing the complexity of direct mechanical connections.
