Solution Overview

Problem

Conventional varmint traps, such as glue traps, often fail to securely capture rodents due to lack of force application, allowing animals to step on or avoid the adhesive, especially in colder conditions where adhesives are less sticky.

Innovation Solution

A varmint control device featuring a housing with an elevated opening and a ramp leading to an adhesive surface, where the varmint must jump or fall to access bait positioned below, ensuring a more secure trapping mechanism by applying force onto the adhesive.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional glue traps are used without force application mechanism, then the device structure is simple, but the trapping reliability deteriorates because animals can step on or avoid the adhesive

Engineering Contradiction:
Improvetrapping reliabilityVSAvoiddevice structure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent applies preliminary action by positioning the animal on a platform above the adhesive and then releasing it to fall onto the adhesive. The falling action is prepared in advance through the platform design, ensuring the animal applies sufficient force to the adhesive before contact, thereby improving trapping reliability without significantly complicating the device structure.

Inventive Principle:
Principle #10Preliminary action

2Reliability

If adhesive is used without force application, then the device is simple to operate, but the adhesive effectiveness deteriorates in colder conditions where adhesives are less sticky

Engineering Contradiction:
Improveadhesive effectivenessVSAvoidoperation simplicity
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The platform mechanism prepares the animal's falling motion in advance, ensuring that sufficient force is applied to the adhesive upon contact. This preliminary preparation of the falling action compensates for reduced adhesive stickiness in colder conditions, maintaining trapping effectiveness while requiring minimal operational intervention from the user.

Inventive Principle:
Principle #10Preliminary action

3Reliability

If animals are forced to jump or fall onto adhesive, then capture security is improved, but the device complexity increases due to additional structural components

Engineering Contradiction:
Improvecapture securityVSAvoidstructural components
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The device is segmented into distinct functional components: a housing structure, an elevated platform, and an adhesive surface. This segmentation allows each component to perform its specific function independently - the platform provides the falling mechanism while the adhesive provides the trapping function - thereby achieving improved capture security with manageable structural complexity.

Inventive Principle:
Principle #1Segmentation

AI summary

A device for trapping a rodent includes one or more of a floor, walls connected to the floor, an aperture in at least one of the walls, and a platform positioned within the container. The platform is positioned adjacent to the aperture and elevated above the floor. An adhesive is positioned on the floor. The aperture is sized to permit a rodent to gain access to the platform.
