Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If physical detection module circuits are installed in the central block, then surface orientation sensing function is achieved, but the user cannot adjust the axis and floating amplitude
Solution Approach 1:
The patent divides the sensing system into separate modular components: detection modules are integrated into individual blocks rather than centralized in the central block, allowing independent adjustment of the central block's axis and floating amplitude while maintaining sensing functionality in other blocks
Solution Approach 2:
The patent introduces a magnetic field as an intermediary for signal transmission between the detection modules and the control unit, eliminating the need for direct electrical connections that would constrain mechanical adjustment
2Reliability
If wire welding and FPC flat wire welding are used for sensors, then electrical connections are established, but welding cost increases and wire breakage occurs in long-term use
Solution Approach 1:
The patent replaces mechanical welding connections with magnetic field-based wireless communication between components, eliminating welding operations entirely and using magnetic coupling for both power transmission and data communication
Solution Approach 2:
The magnetic coupling mechanism serves multiple functions simultaneously: it provides both electrical power transmission and data communication between the detection modules and control unit, replacing multiple separate connection systems
