Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If UV LED lamp beads with fixed wavelength are used, then device complexity is reduced, but mosquito-trapping effect deteriorates due to simple spectrum
Solution Approach 1:
The light source is segmented into multiple LED chips with different wavelengths (360nm, 380nm, 400nm) instead of using a single fixed-wavelength LED. Each wavelength targets different mosquito phototaxis responses, creating a composite spectrum that covers broader mosquito attraction ranges while maintaining manageable device complexity through modular chip arrangement.
Solution Approach 2:
The patent combines multiple LED chips with different wavelengths into a composite light source system. This composite approach creates a multi-wavelength spectrum that leverages the phototaxis responses of mosquitoes to different wavelengths, achieving enhanced trapping effectiveness without requiring complex mechanical or optical systems.
2Adaptability or versatility
If UV lamp tube with wide wavelength range is used, then mosquito-trapping effect is improved, but power waste increases
Solution Approach 1:
Instead of using a broad-spectrum UV lamp tube that emits across a wide wavelength range, the patent applies local quality by selecting specific discrete wavelengths (360nm, 380nm, 400nm) that are most effective for mosquito attraction. Each LED chip emits at a targeted wavelength with high efficiency, avoiding the energy waste associated with emitting wavelengths that do not effectively attract mosquitoes.
Solution Approach 2:
The patent changes the wavelength parameter from a continuous wide range (UV lamp tube) to discrete optimized values (360nm, 380nm, 400nm LED chips). This parameter optimization ensures that energy is concentrated at wavelengths proven to be most effective for mosquito phototaxis, significantly reducing power waste while maintaining or improving trapping effectiveness.
