Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional proximity detection systems are deployed, then collision detection capability is improved, but system cost and installation complexity increase significantly
Solution Approach 1:
The patent extracts the collision detection function into a simple, standalone motion-activated warning light unit that can be independently deployed. Instead of requiring complex integrated systems with multiple sensors and processors, the invention uses a single unit containing a motion sensor, warning light, and power source that performs collision detection and warning functions autonomously.
Solution Approach 2:
The patent employs inexpensive, easily replaceable components including standard LEDs for warning lights, common motion sensors, and readily available batteries. These components are designed to be low-cost and easily replaceable, allowing widespread deployment without significant investment in expensive, hard-to-maintain systems.
2Measurement precision
If specialized transmitters and detectors are used, then detection precision is improved, but installation time and cost increase
Solution Approach 1:
The warning light unit is designed as a self-contained system that requires no specialized installation services. The unit includes an integrated power source (batteries), motion sensor, and warning light, allowing warehouse workers to install it themselves by simply mounting the unit and connecting the cable to the power source, eliminating the need for technical installers or specialized equipment.
Solution Approach 2:
The patent designs a universal mounting system that can be attached to various surfaces (walls, pillars, shelves) using standard mounting methods. The cable connection system is designed to work with different power sources and configurations, making the system adaptable to any location without requiring location-specific installation procedures.
3Reliability
If multiple independent mode systems are deployed, then collision avoidance coverage is improved, but system management complexity increases
Solution Approach 1:
The patent divides the collision avoidance system into multiple independent, identical warning light units, each covering a specific area. Each unit operates autonomously with its own motion sensor and warning light, eliminating the need for complex system management. Units can be deployed in multiple locations throughout the warehouse, providing comprehensive coverage while maintaining simple, uniform management procedures for each unit.
