Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If LEDs are operated with high currents for high light output, then radiation intensity is improved, but service life decreases due to heat generation
Solution Approach 1:
The patent extracts the heat dissipation function from the LED housing by implementing a separate coolant circulation system with channels that remove heat from the LED mounting area, allowing the LED to operate at high currents without excessive temperature buildup that would reduce service life
Solution Approach 2:
The patent introduces a coolant as an intermediary substance that absorbs heat from the LED and transports it away through circulation channels, enabling the LED to maintain high radiation intensity while the coolant prevents thermal damage that would otherwise shorten service life
2Illumination intensity
If the number of LEDs is increased to achieve desired light output, then radiation intensity is improved, but device complexity increases
Solution Approach 1:
The patent combines multiple LEDs onto a single circuit board mounted within the housing, integrating their functions into one consolidated unit that achieves the desired luminous power while reducing the overall complexity compared to distributing multiple separate LED assemblies throughout the system
3Duration of action of stationary object
If traditional discharge lamps are used, then radiation intensity is maintained over time, but power consumption increases
Solution Approach 1:
The patent changes the operating parameters by using LEDs that operate at low voltage and current compared to traditional discharge lamps, achieving comparable service life and radiation intensity while consuming significantly less electrical power due to the different operational characteristics of semiconductor LEDs versus gas discharge lamps
4Duration of action of stationary object
If LEDs are operated below nominal power to avoid heat, then service life is improved, but radiation intensity decreases
Solution Approach 1:
The patent uses a coolant circulation system as an intermediary heat removal mechanism that allows LEDs to operate at or near nominal power by actively managing thermal buildup, thereby maintaining high luminous power output while preventing the temperature-related degradation that would otherwise necessitate operating below nominal power
