Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a handle is used to lock the arc bulge into the arc groove for seal connection, then the quick joint can be fixedly connected, but the handle occupies large space and has a complex structure
Solution Approach 1:
The patent removes the traditional handle component entirely and replaces it with a cam mechanism consisting of a cam member and cam follower. This extraction of the handle simplifies the overall structure while maintaining the locking and sealing functions through the cam profile geometry that directly engages with the coupling body.
Solution Approach 2:
Instead of using a handle to actively lock the connection, the patent uses a cam mechanism where the cam follower passively follows the cam profile. The locking action is inverted from manual handle operation to automatic cam-driven engagement, where the cam member rotates to provide mechanical advantage and secure the connection.
2Reliability
If the handle is strongly pressed to achieve fixed connection, then the connection is secure, but assembly wastes time and labor
Solution Approach 1:
The patent employs a dynamic cam mechanism where the cam member can rotate to different positions. During assembly, the cam member is rotated to the engaged position, providing mechanical advantage that secures the connection. For disassembly, the cam member is simply rotated to a disengaged position, enabling rapid release without forcing or strong pressing actions.
Solution Approach 2:
The cam mechanism is pre-configured with specific profile geometry that automatically provides the locking action upon engagement. The cam follower is pre-positioned to engage with the cam profile, so that when the cam member is rotated into place, the sealing surfaces are automatically pressed together with the required force, eliminating the need for additional strong pressing during assembly.
3Reliability
If the handle structure is used for quick joint, then the connection can be made, but high machining accuracy is necessary to ensure sealing performance
Solution Approach 1:
The patent replaces the traditional handle-based mechanical system with a cam mechanism where the sealing force is generated through the cam profile geometry. The cam member's rotation provides controlled mechanical advantage, distributing the sealing force through the cam follower onto the sealing surface. This substitution reduces the need for high machining accuracy compared to direct handle pressing, as the cam profile can compensate for minor variations and provide more uniform force distribution.
4Productivity
If a simple structure is adopted for quick joint, then assembly efficiency improves, but sealing performance may be compromised
Solution Approach 1:
The cam mechanism provides dynamic control over the sealing force through rotation. By rotating the cam member to different positions, the operator can control the engagement level and sealing pressure. This dynamic adjustment capability allows the simple cam structure to achieve reliable sealing performance while maintaining quick assembly and disassembly efficiency.
Solution Approach 2:
The cam profile geometry is specifically designed with optimized parameters to generate the required sealing force during rotation. The cam profile shape, radius, and engagement angle are carefully selected to ensure that as the cam member rotates into the engaged position, it applies the necessary pressure to the sealing surfaces through the cam follower, achieving reliable sealing with a simple structure.
