Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional bolts are used for fastening, then the connection can be achieved, but the bolt lacks automatic positioning function causing inconvenience in use
Solution Approach 1:
The patent implements nesting by placing the positioning rod inside the insert rod, which is in turn inside the mounting hole of the bolt body. The compression spring is nested within the mounting hole surrounding the insert rod. This nested arrangement enables the automatic positioning function while keeping the overall bolt structure compact and not excessively complex.
Solution Approach 2:
The positioning rod automatically positions itself through the interaction of the compression spring and magnet rod. When the bolt is inserted, the compression spring pushes the insert rod and positioning rod to automatically align with the positioning hole, eliminating the need for manual positioning operations.
2Manufacturing precision
If the bolt structure is simplified, then the manufacturing is easier, but the positioning accuracy and connection stability are reduced
Solution Approach 1:
The patent replaces complex mechanical positioning mechanisms with a magnetic field-based positioning system. The magnet rod generates a magnetic field that interacts with ferromagnetic materials in the positioning hole, achieving precise positioning without complex mechanical guides or adjustment mechanisms, thereby improving positioning accuracy while maintaining manufacturing simplicity.
Solution Approach 2:
The patent uses the magnetic field strength parameter of the magnet rod to achieve positioning. By adjusting the magnetic field parameters rather than complex mechanical dimensions, the positioning accuracy is improved while the manufacturing process remains relatively simple, as magnetic properties can be controlled during material selection and processing.
