Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing flying pest traps have inefficiencies in light distribution, particularly when using LEDs, resulting in 'dead' areas on the glueboard and reduced effectiveness due to the positioning constraints of LED light sources compared to fluorescent tubes.

Innovation Solution

The arrangement of LEDs behind the glueboard with strategically placed apertures allows even light distribution across the glueboard, combined with fluorescent light sources for enhanced attraction and immobilization, and a translucent carrier to secure the glueboard and PCB, ensuring consistent power delivery.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Illumination intensity

If LED light sources are positioned in front of the glueboard, then the attraction section can provide broad pest attraction, but 'dead' areas appear on the glueboard where light does not reach

Engineering Contradiction:

Improvelight distribution uniformityVSAvoidtrap effectiveness

Core Design Contradiction:

Illumination intensityVSReliability

Solution Approach 1:

The patent inverts the conventional arrangement by positioning LED light sources behind the glueboard rather than in front. This inversion allows light to pass through the glueboard material, eliminating shadowed areas and ensuring uniform illumination across the entire glueboard surface, thereby resolving the dead areas problem while maintaining trap effectiveness

Inventive Principle:

Principle #13The other way round (Inversion)

2Productivity

If fluorescent tube-type light sources are used, then broad pest attraction is achieved, but the positioning constraints limit light distribution efficiency

Engineering Contradiction:

Improvelight distribution efficiencyVSAvoidpositioning constraints

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The patent replaces the mechanical positioning constraints of fluorescent tube-type light sources with LED technology. LEDs can be positioned flexibly behind the glueboard and still provide effective illumination, eliminating the need for complex positioning mechanisms while improving light distribution efficiency and maintaining broad pest attraction capabilities

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)
