Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If fluorescent tubes are used to emit UV light for attracting insects, then insect attraction is effective, but the device has short lifespan and environmental harm due to mercury content

Engineering Contradiction:

Core Design Contradiction:
ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The patent changes the light source parameters from fluorescent tubes to LEDs, specifically using blue LEDs with wavelength 440-480nm. This parameter change eliminates mercury content and extends lifespan while maintaining insect attraction effectiveness through the specific wavelength range that insects are sensitive to

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent replaces the fluorescent tube mechanism with LED technology, substituting the gas discharge mechanism with electroluminescence in solid-state devices. This substitution eliminates the harmful mercury component and provides longer operational reliability

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Reliability

If LEDs are used to emit light for attracting insects, then lifespan is extended and environmental harm is reduced, but direct light emission causes eye and skin damage

Engineering Contradiction:
ImprovelifespanVSAvoideye and skin damage
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent introduces yellow glass filters as an intermediary between the blue LEDs and the external environment. These filters transmit wavelengths that attract insects (380-480nm range) while blocking the harmful direct blue light, thus mediating between the LED light source and the external space to eliminate eye and skin damage risks

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent applies different optical properties to different parts of the housing: the front surface uses yellow glass filters with specific transmission characteristics for insect attraction, while side surfaces use opaque or diffusing materials to prevent direct light emission in other directions, creating localized light emission zones with different qualities
