Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional lighting systems are installed with extensive wiring and power infrastructure, then lighting coverage and reliability are improved, but installation cost and complexity increase significantly
Solution Approach 1:
The patent replaces extensive physical wiring infrastructure with wireless communication technology. Lighting fixtures communicate with the central control system via wireless signals, eliminating the need for complex wired networks while maintaining system reliability and control capabilities.
Solution Approach 2:
The lighting fixtures are designed as multi-functional units that combine illumination, sensing, and wireless communication capabilities. This universal design allows a single device to perform multiple functions, reducing the need for separate wiring for control and data transmission.
2Ease of manufacture
If conventional lighting systems use standardized fixtures, then ease of installation is improved, but adaptability to different environmental conditions deteriorates
Solution Approach 1:
The lighting system incorporates dynamically adjustable parameters including variable light intensity, adjustable color temperature, and reconfigurable beam angles. These dynamic capabilities allow standardized fixtures to adapt to different environmental conditions and application requirements without requiring custom hardware for each scenario.
Solution Approach 2:
The system changes operational parameters such as luminous output, color rendering, and beam direction to suit different environments. Sensors detect environmental conditions and automatically adjust lighting parameters to optimize performance for warehouses, retail spaces, outdoor areas, and other diverse settings.
3Quantity of substance
If conventional systems use basic occupancy or ambient light sensors, then cost is reduced, but effectiveness in various environmental conditions deteriorates
Solution Approach 1:
The patent merges multiple sensing functions into an integrated sensor module within each lighting fixture. This combination of occupancy detection, ambient light sensing, and environmental monitoring capabilities in a single unit reduces overall system cost while improving reliability through coordinated sensor operation and data processing.
