Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If broad-spectrum lighting is used to control pests, then pest control coverage is improved, but harmful effects on beneficial organisms and crops increase
Solution Approach 1:
The system applies different wavelengths of light to different targets: specific wavelengths that are harmful to pests are applied only when pests are detected, while other wavelengths safe for crops and beneficial organisms are used during normal growth periods. This spatial and temporal differentiation of light properties resolves the contradiction between effective pest control and protection of beneficial organisms.
Solution Approach 2:
The system dynamically changes the wavelength parameter of the light source based on detection results. When pests are detected, the light wavelength is changed to a pest-specific harmful wavelength; when no pests are present, the wavelength is adjusted to be safe for crops and beneficial organisms. This parameter modulation allows the system to achieve both effective pest control and minimal harm to non-target organisms.
2Device complexity
If fixed wavelength light is used for pest control, then system simplicity is improved, but control effectiveness against diverse pest species deteriorates
Solution Approach 1:
The system transitions from a fixed wavelength light source to a dynamic wavelength selection system. The wavelength of the light source is adjusted in real-time based on the detection results and the identified pest species. This dynamic adaptation allows the system to maintain effectiveness against diverse pest species while adding only moderate complexity through wavelength control mechanisms.
Solution Approach 2:
The light source is designed to perform multiple functions by emitting different wavelengths: it can target different pest species with species-specific wavelengths, and it can also provide safe illumination for crops and beneficial organisms. This multi-functionality is achieved through a wavelength-selective light source that can be programmed to emit various wavelengths based on detection results, resolving the contradiction between simplicity and effectiveness.
3Reliability
If continuous lighting is used for pest control, then pest detection reliability is improved, but energy consumption and costs increase
Solution Approach 1:
The system replaces continuous lighting with periodic illumination synchronized to the detection cycle. The light source is activated only during detection periods when pest identification is required, and remains off during intervals between detections. This periodic operation maintains pest detection reliability by ensuring adequate illumination during critical detection moments while dramatically reducing overall energy consumption compared to continuous lighting.
4Measurement precision
If species-specific wavelengths are used for pest control, then control precision is improved, but device complexity increases
Solution Approach 1:
The system introduces a wavelength selection module as an intermediary between the light source and the target. This module acts as a mediator that selects and directs the appropriate wavelength based on detection results, enabling precise targeting of different pest species without requiring multiple independent light sources. The intermediary wavelength selector maintains control precision while limiting the increase in device complexity through a centralized control mechanism.
