Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If multiple LEDs with lenses and glare reduction screens are used to meet glare requirements, then visual comfort is improved, but device complexity and bulk increase
Solution Approach 1:
The patent combines the glare reduction screen with the optical element (lens) into a single integrated component. The grid pattern is directly formed on the optical element itself, eliminating the need for separate glare reduction screens positioned in front of each LED, thereby reducing device complexity while maintaining glare control functionality
Solution Approach 2:
The optical element serves multiple functions simultaneously: it focuses light from the LED, reduces glare through its integrated grid pattern, and acts as a protective cover. This multi-functionality eliminates the need for separate dedicated glare reduction components for each LED
2Object-affected harmful factors
If multiple LEDs with lenses and glare reduction screens are used to meet glare requirements, then visual comfort is improved, but the device becomes bulky
Solution Approach 1:
By merging the glare reduction grid with the optical element into a single integrated component, the patent significantly reduces the overall device volume. The elimination of separate glare reduction screens positioned in front of each LED removes unnecessary spatial requirements while maintaining effective glare control
3Illumination intensity
If LEDs are arranged to maximize light points and functional surface area, then optical performance is improved, but the pitch between LEDs becomes very limited
Solution Approach 1:
The patent transitions from conventional square or rectangular LED arrangements to a hexagonal honeycomb pattern. This geometric transformation allows for more efficient space utilization, maximizing the number of LEDs and functional surface area within the same footprint while maintaining adequate pitch between adjacent LEDs through the optimal geometry of hexagonal cells
