Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If traditional upper and lower rocker arm structure is used, then the rocker device can provide stable mechanical support, but the overall thickness of the rocker device becomes too large
Solution Approach 1:
The patent extracts and removes the traditional upper and lower rocker arm components from the system. Instead of using these mechanical arms for position detection, the invention employs a hall sensor assembly that directly detects the position of the rocker rod through magnetic field sensing, thereby eliminating the thickness contribution of the rocker arms while maintaining detection functionality
Solution Approach 2:
The patent replaces the mechanical rocker arm detection system with an electromagnetic sensing system. The hall sensor assembly uses magnetic field detection instead of mechanical contact and movement to determine rocker position, substituting complex mechanical structures with a more compact electromagnetic sensing approach
2Length of moving object
If traditional mechanical detection method is used, then the position information can be obtained through mechanical contact, but the rocker device requires more components increasing its thickness
Solution Approach 1:
The patent substitutes mechanical position detection with electromagnetic field-based hall sensor detection. The hall sensor assembly detects the position of the rocker rod by sensing changes in magnetic field strength as the rod moves, providing accurate position information without requiring the physical space needed for mechanical detection components
Solution Approach 2:
The patent introduces a magnetic field as an intermediary between the rocker rod and the detection system. The magnet attached to the rocker rod generates a magnetic field that the hall sensor detects, allowing indirect but accurate position measurement without direct mechanical contact or complex linkages
