Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wired data transmission is used, then data transmission reliability is improved, but device complexity and installation difficulty increase
Solution Approach 1:
The patent replaces wired mechanical connections with wireless optical communication (laser-based data transmission). The sensor module communicates with the external system through laser beams without physical cable connections, eliminating the need for complex wiring installation while maintaining data transmission reliability in harsh environments.
2Stability of the object's composition
If external power source is used, then power supply stability is improved, but device portability and ease of deployment worsen
Solution Approach 1:
The sensor module is equipped with an integrated power supply unit that provides self-contained power operation. The device can independently power its LIDAR sensors, processing unit, and wireless communication module without requiring external power sources, enabling portable deployment while maintaining stable operation through internal power management.
3Measurement precision
If matrix module with multiple laser emission points is used, then measurement precision and mapping capability are improved, but device complexity increases
Solution Approach 1:
The measurement function is segmented into multiple independent laser emission points arranged in a matrix configuration. Each laser point operates independently to measure distance to the liquid surface, enabling multi-point simultaneous measurement that improves precision and creates detailed surface mapping while distributing the complexity across modular sensor elements.
Solution Approach 2:
The patent transitions from single-point measurement to multi-point matrix measurement by adding spatial dimensionality. The multiple laser emission points are arranged in a two-dimensional matrix pattern, enabling simultaneous measurement across different spatial locations and providing comprehensive surface mapping capability.
4Reliability
If device is designed for explosive environments, then safety and reliability are improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The sensor module is designed with intrinsic safety features suitable for explosive environments. The electronic components and power supply are configured to operate at safe voltage and current levels that prevent ignition of explosive atmospheres, effectively creating an intrinsically safe operating environment without requiring complex additional safety systems.
