Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of stationary object
If light-emitting diodes are used in photochemical reactors, then service life is improved, but heat dissipation becomes more difficult due to limited space for coolant circulation
Solution Approach 1:
The support structure is divided into multiple segments with cooling channels integrated within each segment, allowing distributed heat dissipation throughout the LED array rather than concentrating cooling requirements at a single location
Solution Approach 2:
The support structure merges multiple functions: mechanical support for LEDs, thermal conduction path for heat dissipation, and structural framework for the reaction medium, eliminating the need for separate cooling components
2Loss of energy
If LED lamps are used in immersion photochemical reactors, then luminous efficiency is improved, but device complexity increases due to cooling requirements
Solution Approach 1:
The support structure merges multiple functions: mechanical support for LEDs, thermal conduction path for heat dissipation, and structural framework for the reaction medium, eliminating the need for separate cooling components
Solution Approach 2:
The support structure serves multiple purposes simultaneously: it provides mechanical support, conducts heat away from LEDs, and maintains the structural integrity of the immersion reactor setup
3Use of energy by moving object
If mercury or sodium vapor lamps are replaced with LEDs, then energy consumption is reduced, but compatibility with existing facilities requires footprint similarity
Solution Approach 1:
The LED array is arranged in a three-dimensional configuration along the support structure, allowing increased luminous output without proportionally increasing the horizontal footprint, thus maintaining compatibility with existing reactor geometries
