Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a biasing member is used to restore the shaft-shaped member to its initial position, then the controller returns to its initial position after tilting operation, but the resistive feel to the tilting operation is almost constant and cannot be adjusted by users
Solution Approach 1:
The patent introduces an adjustable mechanism that allows the biasing force to be dynamically changed. The operating body can be positioned at different locations along the shaft, and the biasing member's effective length and force can be adjusted accordingly, transforming the static resistive feel into a dynamic, user-adjustable parameter while maintaining the restoration function.
Solution Approach 2:
The patent changes the physical parameters of the biasing system by allowing adjustment of the biasing member's compression length and the operating body's position. This enables the resistive feel to be modified by changing the spring constant and effective length parameters, providing users with adjustable resistance while maintaining reliable restoration to the initial position.
2Force
If the biasing force is increased to provide stronger resistive feel for delicate operations, then the resistive feel becomes sufficient for precise operations, but it may cause discomfort for users who prefer lighter resistance
Solution Approach 1:
The patent makes the resistive force dynamic and adjustable rather than fixed. Users can modify the biasing force by repositioning the operating body or adjusting the biasing member's compression, allowing the force to be optimized for both delicate operations and general comfort according to individual preferences and task requirements.
Solution Approach 2:
The patent enables adjustment of the force parameter by changing the physical configuration of the biasing system. By modifying the compression length and effective lever arm of the biasing member, the resistive force can be tuned to provide sufficient resistance for precise operations while remaining comfortable for users with different preferences.
3Force
If the biasing member is positioned to provide adequate resistive feel, then the tilting operation has sufficient resistance for precise control, but the structure becomes more complex with additional adjustment mechanisms
Solution Approach 1:
The patent integrates the adjustment function into the existing operating body and shaft structure. The operating body serves both as the user interface for tilting operations and as the adjustment mechanism for resistive feel, while the shaft structure provides both support and the adjustment track. This multi-functionality reduces the need for separate adjustment components, minimizing added complexity.
Solution Approach 2:
The patent enables users to adjust the resistive feel themselves without requiring external tools or complex adjustment mechanisms. The operating body can be repositioned along the shaft by the user's own hands, and the biasing member automatically adjusts its compression based on the new position, providing a self-service adjustment system that maintains simplicity.
