Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If signal-cable and power-cable are used to transmit temperature data and power, then the molecular diagnostics apparatus can function, but the reliability of transmission is low and the mechanism design becomes complicated
Solution Approach 1:
The patent replaces the mechanical cable connection system with an electromagnetic induction system. The power supply coil generates a magnetic field that induces current in the detection module, eliminating the need for physical power-cable and signal-cable connections. This substitution resolves the contradiction by improving reliability through contactless transmission while reducing mechanism complexity.
Solution Approach 2:
The patent introduces a magnetic field as an intermediary between the power supply coil and the detection module. The magnetic field serves as the medium for energy and signal transmission, replacing direct cable connections. This intermediary approach enables reliable wireless power and data transmission while simplifying the overall system structure.
2Adaptability or versatility
If rotational carrier with cables is used, then temperature detection can be performed during rotation, but the cables reduce system reliability and increase complexity
Solution Approach 1:
The patent replaces the cable-based power and signal transmission system with an electromagnetic induction system that works during rotation. The power supply coil and detection module are both mounted on the rotational carrier, allowing magnetic field-based energy transfer without physical cable connections. This enables rotation capability while eliminating cable management complexity.
3Ease of manufacture
If cables are used for power and signal transmission, then the apparatus can be constructed, but the reliability is low due to cable connection issues
Solution Approach 1:
The patent replaces mechanical cable connections with electromagnetic induction for power and signal transmission. The power supply coil and detection module are constructed with magnetic field coupling, eliminating connection points that could fail. This maintains construction feasibility while dramatically improving connection reliability through contactless energy and data transfer.
