Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If additional connectors like bolts are used for rod connection, then connection stability is improved, but assembly complexity and operation difficulty increase
Solution Approach 1:
The patent combines the connector and the rod into an integrated structure where the connector is disposed within the rod body. This merging eliminates the need for separate additional connectors while maintaining connection stability through the integrated design of the connector components (connector body, connector head, limiting component) working together with the rod structure.
Solution Approach 2:
The connector components are nested within the rod structure. The connector body is disposed in the rod, the limiting component is arranged in the rod, and the connector head extends from the rod end. This nesting arrangement allows the connector functionality to be embedded within the rod without increasing overall complexity.
2Reliability
If additional connectors like bolts are used for rod connection, then connection stability is improved, but ease of operation deteriorates
Solution Approach 1:
The patent extracts the troublesome operation of threading and tightening separate bolts by integrating the connector functionality directly into the rod structure. The limiting component with limiting teeth and the connector head with engagement features provide automatic positioning and securing without requiring users to perform complex threading operations on separate connectors.
Solution Approach 2:
The integrated connector structure provides self-aligning and self-securing functionality. The limiting component with its limiting teeth automatically positions the connector, and the connector head with its engagement features secures the connection without requiring additional manual intervention for threading or tightening separate bolts.
3Strength
If additional connectors are used for rod connection, then connection strength is improved, but assembly time increases
Solution Approach 1:
The connector components are pre-integrated into the rod structure during manufacturing. The connector body, limiting component, and connector head are positioned and secured within the rod before the product reaches the user. This preliminary action eliminates the need for time-consuming assembly operations when the user needs to connect rods.
4Volume of moving object
If telescopic or detachable rod structure is used, then storage and transportation convenience is improved, but connection reliability may deteriorate
Solution Approach 1:
The patent merges the connector functionality with the detachable rod structure, ensuring that each rod segment contains an integrated connector. This merging maintains connection reliability through the robust integrated connector design while preserving the telescopic or detachable nature of the rod for compact storage and transportation.
