Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If LEDs are driven at large voltage and current to meet design standards, then luminous intensity compliance is achieved, but power consumption increases and efficiency decreases
Solution Approach 1:
The patent divides the single light source into multiple LED segments arranged in a circular pattern. Each LED is driven at lower individual power levels, but their combined output achieves the required luminous intensity. The controller independently controls each LED segment, allowing compliance with UL 1971 standards while reducing total power consumption compared to a single high-power LED.
Solution Approach 2:
The patent combines multiple low-power LED light sources to achieve the luminous intensity of a single high-power LED. By merging the optical output of several LEDs driven at efficient current levels, the system meets design standards without requiring large voltage and current that would reduce overall system efficiency.
2Productivity
If multiple lens elements are angularly positioned to direct light, then light distribution efficiency is improved, but device complexity increases
Solution Approach 1:
The patent segments the lens system into multiple discrete lens elements, each positioned at specific angular intervals around the circular LED array. Each lens directs light from its corresponding LED in a specific direction, creating efficient omnidirectional light distribution. This segmented approach improves light distribution efficiency while keeping each individual lens element simple.
Solution Approach 2:
The patent transitions from a single-axis light distribution to three-dimensional omnidirectional distribution by angularly positioning lens elements around the circular LED array. This spatial arrangement in multiple dimensions allows light to be distributed uniformly in all directions, significantly improving light distribution efficiency without requiring complex individual lens designs.
