Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the power of the fan is increased to improve ventilation efficiency, then the ventilation efficiency is improved, but high noises are generated and the service is affected
Solution Approach 1:
The patent changes the air inlet configuration from a single direction to multiple directions (top, bottom, and side inlets), creating three-dimensional air intake. This dimensional change allows the fan to achieve better ventilation efficiency without increasing power, as air enters from multiple angles simultaneously, reducing the need for high-speed operation and thus lowering noise.
Solution Approach 2:
The air inlet is divided into multiple separate inlets positioned at different locations and orientations (top inlet, bottom inlet, side inlet). This segmentation allows each inlet to capture air from different directions, improving overall air intake efficiency without requiring a single high-power fan, thereby reducing noise while maintaining ventilation performance.
2Productivity
If the power of the fan is increased to improve ventilation efficiency, then the ventilation efficiency is improved, but the volume of the fan increases which is not suitable for small-size lights
Solution Approach 1:
By introducing air inlets from multiple dimensions (top, bottom, and sides), the system achieves enhanced ventilation without requiring a larger fan. The multi-directional inlet configuration allows compact fans to effectively draw air from all directions, improving ventilation efficiency while maintaining a small overall device volume suitable for compact lighting applications.
Solution Approach 2:
The ventilation system is segmented into multiple air inlet pathways distributed throughout the device housing. This segmentation allows the use of smaller fans positioned strategically near each inlet, collectively achieving high ventilation efficiency without requiring a single large-volume fan, thus maintaining compact device dimensions.
3Reliability
If a complex structure is designed to prevent UV ray leakage, then the service safety is improved, but the light structure becomes complex and the volume increases
Solution Approach 1:
The patent employs transparent UV-blocking materials for the housing and cover that are thin and transparent, allowing the structure to remain simple and compact while effectively preventing UV ray leakage. These materials provide UV protection without requiring complex shielding structures, maintaining both safety and structural simplicity.
Solution Approach 2:
The housing and cover serve multiple functions: they provide structural support, enable light transmission for illumination, and simultaneously block UV rays for safety. This multi-functionality eliminates the need for separate UV-blocking components, keeping the overall structure simple while ensuring service safety.
4Productivity
If air inlets and outlets are positioned to improve air convection, then the sterilization scope is enlarged, but dead zones are generated where air flow is slow
Solution Approach 1:
The air outlet is divided into multiple outlets positioned at different locations (front, rear, and side outlets) rather than a single outlet. This segmentation ensures that sterilized air is distributed evenly throughout the space, eliminating dead zones where air flow might be slow, while maintaining effective air convection and expanding the sterilization scope uniformly.
Solution Approach 2:
Air outlets are positioned in multiple spatial dimensions (front, rear, and sides) rather than a single direction. This three-dimensional outlet configuration ensures comprehensive air distribution throughout the protected space, eliminating stagnant areas and dead zones, thereby maintaining reliable air circulation while expanding the effective sterilization scope.
