Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If different numbers of data transmission pins are used in NEMA plugs to support different sensor types, then compatibility with various detection control modules is improved, but device complexity and manufacturing cost increase due to multiple housing designs
Solution Approach 1:
The patent applies universality by designing a single standardized NEMA plug housing that can support multiple sensor types (light sensors, voice sensors, infrared sensors, etc.) through a unified data transmission interface. Instead of creating different housing designs for each sensor type, the invention uses one universal housing structure with standardized pins that can accommodate various detection control modules, thereby reducing device complexity while maintaining adaptability.
Solution Approach 2:
The patent segments the NEMA plug into modular components: a standardized housing structure, interchangeable sensor modules, and a unified control board. This segmentation allows different sensor types to be integrated through standardized interfaces without requiring different housing designs, resolving the contradiction between versatility and complexity.
2Adaptability or versatility
If multiple NEMA plug types with different pin configurations are produced, then compatibility with various sensors is improved, but manufacturing cost and waste increase
Solution Approach 1:
The invention uses a universal NEMA plug housing design that can manufacture a single type of plug suitable for all sensor configurations. This eliminates the need to produce multiple housing types with different pin arrangements, significantly reducing manufacturing costs and material waste while maintaining compatibility with various sensors through standardized interfaces.
Solution Approach 2:
The patent changes the approach from varying physical pin configurations to varying software/driver configurations. The standardized hardware interface remains constant, while adaptability to different sensors is achieved through parameter changes in the control system, reducing manufacturing complexity and cost.
3Ease of manufacture
If a single NEMA plug type with standardized pins is used, then manufacturing cost and complexity are reduced, but compatibility with different sensor data protocols deteriorates
Solution Approach 1:
The patent introduces an intermediary layer (the unified control board and driver software) between the standardized NEMA plug hardware and the various sensor data protocols. This intermediary translates different sensor protocols into a unified format that the system can process, maintaining protocol compatibility while using standardized hardware interfaces.
Solution Approach 2:
The invention moves the variability from the physical hardware dimension (pin configurations) to the software/digital dimension (data protocols and drivers). The hardware remains standardized in one dimension while adapting to different protocols through software configuration in another dimension, resolving the contradiction between standardization and compatibility.
4Adaptability or versatility
If different internal control boards are designed for different NEMA plug types, then sensor compatibility is improved, but device complexity and development cost increase
Solution Approach 1:
The patent employs a universal internal control board design that can work with all sensor types through standardized interfaces. Instead of creating different control boards for each sensor type, the invention uses one multi-functional control board that can interface with various sensors through unified data transmission protocols, reducing device complexity while maintaining sensor support capability.
