Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If helmet-based lighting systems are used to illuminate work areas, then workers have portable lighting capability, but the illumination is limited only to where the worker points the light and creates safety concerns due to potential entanglement in confined spaces
Solution Approach 1:
The lighting function is extracted from the helmet and integrated into the fixed task light system mounted on the support structure. This eliminates the need for workers to wear helmet-based lighting devices, removing the safety concerns associated with helmet entanglement while providing more reliable and consistent illumination at the work area.
Solution Approach 2:
Fixed task lights serve as intermediaries between the power source and the work area, providing illumination without requiring direct worker movement or helmet-based systems. The task lights are positioned to illuminate specific work zones, eliminating the need for workers to manually point lights while maintaining safety.
2Object-affected harmful factors
If fixed lighting systems are installed to provide comprehensive illumination, then safety is improved, but the system cannot adapt to varying deck heights and wheelbase lengths
Solution Approach 1:
The task light positioning system incorporates dynamic adjustability, allowing the task lights to be repositioned along the support structure to accommodate varying deck heights and wheelbase lengths. This dynamic capability enables the lighting system to adapt to different configuration scenarios while maintaining comprehensive illumination and safety.
Solution Approach 2:
The task light system is designed with universal mounting capabilities that allow it to function effectively across multiple configuration scenarios. The same task light infrastructure can serve different deck heights and wheelbase lengths through adjustable positioning, eliminating the need for separate lighting systems for each configuration.
3Reliability
If wiring harnesses are installed for each accessory to provide reliable power, then electrical reliability is improved, but the system becomes complex and difficult to reconfigure when accessories need to be moved
Solution Approach 1:
The wiring system utilizes flexible cable assemblies that can be easily routed and repositioned along the support structure. These flexible cables maintain reliable electrical connections while allowing accessories to be moved to different locations without requiring complex wire splicing or cutting operations, reducing overall system complexity.
Solution Approach 2:
The wiring harness system incorporates dynamic routing capabilities with flexible cables that can adapt to changing accessory positions. This allows the electrical connections to remain reliable while the physical layout changes, enabling easy reconfiguration without compromising electrical reliability or increasing complexity.
4Area of stationary object
If multiple wiring harnesses are installed for different zones to ensure coverage, then illumination coverage is improved, but maintenance and installation become more difficult
Solution Approach 1:
The lighting system is divided into modular task light units, each serving a specific zone. This segmentation allows individual task lights to be maintained or replaced independently without affecting other zones, significantly improving ease of repair and installation while maintaining comprehensive illumination coverage across all areas.
Solution Approach 2:
The modular task light design uses standardized components and mounting interfaces that can be applied across all zones. This universality simplifies maintenance and installation procedures, as the same modular units can be installed or replaced in any zone without requiring zone-specific wiring or mounting procedures, while still providing complete area coverage.
