Solution Overview

Problem

Current pest control methods for houseflies, such as chemical repellents, are ineffective and environmentally harmful, lacking solutions that leverage the natural aversion of houseflies to their predators like hornets and spiders.

Innovation Solution

A visual deterrent device that mimics the appearance of hornet nests and spider webs using a transparent receptacle filled with clear liquid and protrusions, mounted near entrances to repel houseflies without chemicals, featuring a removable attachment mechanism for easy maintenance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If chemical repellents are used to repel houseflies, then the repellency effect is achieved, but environmental harm and water insolubility causing runoff contamination occur

Engineering Contradiction:

Improverepellency effectivenessVSAvoidenvironmental contamination

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent replaces chemical repellents with a visual deterrent system that uses optical properties (refraction and reflection) to create predator-like appearances. The clear liquid in the transparent receptacle refracts light to mimic spider webs, while the protrusions and overall structure resemble hornet nests, eliminating the need for harmful chemical substances entirely.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent changes the approach from chemical composition to optical parameter manipulation. By utilizing the refractive index of clear liquid and the reflective properties of protrusions, the system creates visual effects that deter houseflies without introducing harmful substances into the environment.

Inventive Principle:

Principle #35Parameter changes

2Reliability

If sprays and repellants are used to deter houseflies, then the repellency is achieved, but unpleasant smells are generated

Engineering Contradiction:

Improverepellency effectivenessVSAvoidunpleasant odor

Core Design Contradiction:

ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The patent substitutes olfactory-based repellency with visual-based repellency. Instead of releasing unpleasant-smelling chemicals, the system uses optical effects created by light refraction through clear liquid and reflection off protrusions to create predator-like visual appearances that houseflies naturally avoid.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Stability of the object's composition

If permanent mounting is used for the deterrent device, then stable positioning is achieved, but cleaning and maintenance become difficult

Engineering Contradiction:

Improvemounting stabilityVSAvoidcleaning accessibility

Core Design Contradiction:

Stability of the object's compositionVSEase of repair

Solution Approach 1:

The patent divides the mounting system into separate, modular components including a transparent receptacle, attachment mechanism, and support structure. This segmentation allows the receptacle to be easily detached for cleaning and maintenance while the attachment mechanism remains securely mounted on the surface, resolving the conflict between stable positioning and cleaning accessibility.

Inventive Principle:

Principle #1Segmentation

4Reliability

If complex chemical compositions are used for pest control, then repellency effectiveness is improved, but environmental harm and runoff contamination increase

Engineering Contradiction:

Improverepellency effectivenessVSAvoidchemical runoff contamination

Core Design Contradiction:

ReliabilityVSLoss of substance

Solution Approach 1:

The patent replaces complex chemical compositions with a purely physical visual deterrent system. The clear liquid and protrusions create optical effects that mimic predator appearances, eliminating substance loss through runoff while maintaining effective pest deterrence through biological instinct rather than chemical toxicity.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

AI summary

A housefly deterrent device is an apparatus used to deter houseflies from approaching a particular area. The apparatus is also configured to mount to an appropriate area for ease of positioning and maintenance and does not rely on chemical compounds to affect houseflies. The apparatus includes a visual deterrent, an orienting fixture, and an attachment mechanism. The visual deterrent is a structure which mimics the physical appearance of the housing of various predators of houseflies sufficiently to affect the general behavior of houseflies. The orienting fixture is a mount which supports and arranges the visual deterrent in position, preferably adjacent to a door or a building entrance. The attachment mechanism is an arrangement of components that allows for connection of the orienting fixture to surfaces or relevant structures proximal to a target housefly protection zone. The visual deterrent is removable, facilitating adjustment, and general maintenance.
