Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If conventional UV lamps are used in insect traps, then UV light radiation is achieved, but power consumption is high and heat generation is excessive
Solution Approach 1:
The patent changes the fundamental parameter of the light source from conventional UV lamps to UV LEDs, which operate at lower voltages and currents. This parameter change results in significantly reduced power consumption and heat generation while maintaining the necessary UV radiation output for effective insect trapping
Solution Approach 2:
The patent replaces the thermal-mechanical UV lamp system with an electroluminescent UV LED system. This substitution eliminates the need for high-power heating elements and complex ballast circuits, directly reducing power consumption and simplifying the overall system architecture
2Reliability
If conventional UV lamps are used in insect traps, then UV light radiation is achieved, but environmental pollution occurs due to toxic gas
Solution Approach 1:
The patent eliminates the harmful byproduct (toxic gas) inherent in conventional UV lamp operation by adopting UV LEDs. This conversion transforms a harmful lighting solution into an environmentally benign one, as UV LEDs produce light through electroluminescence without generating hazardous emissions
Solution Approach 2:
The patent adopts UV LEDs which have no toxic materials requiring disposal unlike conventional UV lamps containing mercury or other toxic gases. This approach eliminates environmental pollution concerns associated with lamp disposal and recycling
3Use of energy by moving object
If UV LEDs are used without directional control, then power consumption is reduced, but UV light radiates in all directions causing safety issues
Solution Approach 1:
The patent segments the omnidirectional UV radiation pattern into controlled directional beams using reflective surfaces and optical elements. This segmentation allows the trap to maintain low power consumption while directing UV radiation only toward the trapping area, eliminating unnecessary radiation in other directions
Solution Approach 2:
The patent introduces optical intermediaries such as reflective shields and directional lenses between the UV LEDs and the environment. These intermediaries act as mediators that guide UV radiation along desired paths while blocking radiation in unwanted directions, thus controlling the radiation pattern without increasing power consumption
4Productivity
If the fan operates continuously to trap insects, then trapping efficacy is improved, but noise and power consumption increase
Solution Approach 1:
The patent implements periodic operation of the fan based on detected insect presence. Instead of continuous operation, the fan activates only when insects are detected near the trap and remains inactive otherwise. This periodic action maintains high trapping efficacy during active periods while dramatically reducing average power consumption and noise levels
Solution Approach 2:
The patent employs feedback control where sensors detect insect presence and send signals to control fan operation. This feedback mechanism ensures the fan operates only when necessary for trapping, optimizing the balance between trapping efficacy and power consumption by responding to real-time conditions
