Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If components are customized for different shaft sizes, then clamping precision is improved, but manufacturing cost increases and component variety increases
Solution Approach 1:
The clamping unit is designed as a universal component that can accommodate multiple shaft sizes through adjustable mechanisms. The pressing body can be positioned at different locations along the axial direction, and the inclined surface angle can be adjusted, allowing the same clamping unit to adapt to different shaft diameters without requiring multiple specialized components for each size.
Solution Approach 2:
The clamping unit incorporates dynamic adjustment capabilities where the pressing body position and inclined surface angle can be modified based on the shaft size being clamped. This dynamic adaptability allows a single component design to serve multiple functions across different applications, reducing the need for multiple fixed-size components.
2Reliability
If components are customized for different shaft sizes, then clamping performance is improved, but production cost increases
Solution Approach 1:
By designing the clamping unit as a universal component with adjustment mechanisms, the patent eliminates the need to manufacture multiple specialized components for different shaft sizes. This single-component-multiple-uses approach significantly reduces production costs while maintaining reliable clamping performance through proper adjustment for each application.
Solution Approach 2:
The patent utilizes parameter changes (adjustable pressing body position, variable inclined surface angle) to adapt the clamping unit to different shaft sizes. This allows the same physical component to achieve optimal clamping performance for various dimensions without requiring different component designs, thereby reducing manufacturing costs.
3Adaptability or versatility
If multiple component sizes are prepared, then adaptability to different shafts is improved, but inventory complexity increases
Solution Approach 1:
The clamping unit is designed as a universal component that can serve multiple shaft sizes through adjustment mechanisms. Instead of maintaining inventory of multiple specialized components for different shaft diameters, the patent uses a single adjustable clamping unit design, significantly simplifying inventory management while maintaining full adaptability.
Applied Scientific Principles

Function Achieved in This Case
The solution enables a common clamping unit to be used across various shaft diameters, reducing the number of components needed and lowering production costs while maintaining effective clamping and ease of use.
Implementation Method 1
a first biasing member that biases the operation member in the pressing promotion direction
Implementation Method 2
The inclined surface is configured to increase the protruding amount of the pressing body from the case when the movable body changes in position as the operation member moves in the pressing promotion direction

AI summary
A clamping unit includes a case with a contact surface, an operation member arranged movable in a pressing cancellation direction and a pressing promotion direction relative to the case, a pressing body arranged in a movable manner in the case to oppose the contact surface, and a movable body between the pressing body and contact surface. At least one of the contact surface, movable body, and pressing body includes an inclined surface. The inclined surface increases a protruding amount of the pressing body from the case when the movable body changes in position as the operation member moves in the pressing promotion direction and eases pressing of the movable body against the pressing body when the movable body changes in position as the operation member moves in the pressing cancellation direction to permit a decrease in the protruding amount of the pressing body from the case.
