Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a pin and knurled screw fastening mechanism is used to hold the force transmission element, then the force transmission element is securely held, but the pin is easily lost during handling and requires additional work steps for assembly
Solution Approach 1:
The patent extracts the fastening function from the mechanical pin and knurled screw system and replaces it with a magnetic field-based retention mechanism. The magnet integrated into the force transmission element provides secure holding without requiring separate fastening components, thereby eliminating the complexity of assembly while maintaining reliability.
Solution Approach 2:
The patent replaces the mechanical fastening system (pin and knurled screw) with a magnetic retention system. The magnet creates a magnetic field that holds the force transmission element in place, substituting mechanical fastening with electromagnetic interaction, which simplifies the overall structure and reduces assembly steps.
2Reliability
If the force transmission element is held by a pin and knurled screw, then it can be securely fastened, but the force measurement becomes falsified due to susceptibility to tilting
Solution Approach 1:
The patent replaces the mechanical pin and knurled screw fastening system with a magnetic retention mechanism. This substitution eliminates the tilting issue because the magnetic field provides uniform retention forces that prevent lateral displacement and tilting of the force transmission element, thereby maintaining both secure fastening and measurement precision.
Solution Approach 2:
The patent changes the retention mechanism from mechanical contact forces to magnetic field forces. This parameter change in the fastening approach allows for more uniform force distribution and eliminates the tilting problem that occurs with mechanical fastening, thus improving measurement accuracy while maintaining secure holding.
3Ease of manufacture
If the force absorption element is screwed to the adapter plate with a central screw, then it can be fastened, but measurement inaccuracies occur due to alignment issues
Solution Approach 1:
The patent replaces the screw-based fastening system with magnetic retention. This eliminates the alignment issues inherent in screw fastening because the magnetic field automatically centers and holds the force transmission element without requiring precise manual alignment, thereby improving measurement precision while maintaining ease of assembly.
