Engineering Contradiction Analysis
1Area of stationary object
If multiple sensor elements are arranged on a traditional planar circuit board, then the detection region can be extended, but the main detection directions remain parallel and additional mounting components are required for tilting
Solution Approach 1:
The substrate body merges the mechanical support function, circuit carrier function, and sensor mounting function into a single integrated component. Sensor elements are directly arranged on the three-dimensionally structured substrate body, eliminating the need for separate mounting components and enabling tilted detection directions while extending the total detection region.
Solution Approach 2:
The substrate body is designed as a three-dimensional structure with varying heights and tilted surfaces, allowing sensor elements to be arranged at different angles and positions. This dimensional complexity enables extended detection regions with non-parallel main detection directions without requiring additional mounting hardware.
2Adaptability or versatility
If different types of sensor elements are used to detect different variables, then the detection capability is enhanced, but the logistical complexity in manufacturing increases
Solution Approach 1:
The substrate body serves as a universal platform that can accommodate different types of sensor elements (motion detectors, brightness sensors, etc.) with different detection regions and detection variables. The standardized substrate design allows for versatile sensor configurations without requiring different mounting procedures or additional components for each sensor type.
3Ease of manufacture
If sensor elements are arranged on a planar circuit board, then the integration is simple, but the detection regions cannot be tilted and the integration depth is limited
Solution Approach 1:
The substrate body transitions from a two-dimensional planar structure to a three-dimensional form with tilted surfaces and varying elevations. This allows sensor elements to be arranged with tilted main detection directions while maintaining direct integration on the substrate body, combining manufacturing simplicity with detection versatility.
