Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the detection coil head and oscillation tuned circuit are separately provided, then the detection function is achieved, but the configuration becomes complicated and production cost increases
Solution Approach 1:
The patent combines the oscillation circuit and detection device into a single integrated unit on one circuit board. The oscillation circuit includes a coil and capacitor that generate oscillations, while the detection device measures frequency changes caused by metal powder adsorption. This integration eliminates the need for separate production and electrical connection of distinct components, thereby simplifying the overall sensor configuration while maintaining the detection function.
Solution Approach 2:
The integrated circuit board serves multiple functions: it provides the oscillation generation capability through the coil and capacitor, performs detection through frequency measurement, and enables signal processing. By making the circuit board multi-functional, the patent reduces the number of separate components needed, thus simplifying the sensor configuration without compromising detection reliability.
2Reliability
If the detection coil head and oscillation tuned circuit are separately provided, then the detection function is achieved, but the number of assembly steps increases and production cost increases
Solution Approach 1:
The oscillation circuit components (coil, capacitor) and detection device are merged into a single integrated assembly on one circuit board. This eliminates the need for separate assembly steps for mounting and electrically connecting distinct detection coil heads and oscillation tuned circuits, thereby reducing the number of assembly steps and production cost while maintaining detection function reliability.
3Reliability
If separate production of detection coil head and oscillation tuned circuit is performed, then component specialization is achieved, but the number of parts increases and cost increases
Solution Approach 1:
The patent merges multiple functional components (oscillation circuit with coil and capacitor, detection device) into a single integrated unit on one circuit board. This reduces the total number of separate parts from multiple discrete components to a unified assembly, thereby decreasing the quantity of parts and associated production cost while maintaining the specialized functions needed for reliable detection.
