Solution Overview

Problem

Existing methods for eradicating moles are labor-intensive, destructive to lawns, unsafe for children and pets, and environmentally impactful, with inefficient trap placement and retrieval processes.

Innovation Solution

A mole eradication system featuring a sleeve and rod with radially extending sharps that can be easily positioned and retrieved without digging, using a twist-lock mechanism to expose and conceal the sharps for safe and effective mole capture.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional traps are installed by digging into the ground, then mole eradication effectiveness is improved, but labor intensity and lawn destruction increase

Engineering Contradiction:

Improvemole eradication effectivenessVSAvoidlabor intensity

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The sharp killing mechanism is extracted from the traditional in-ground trap and repositioned to the surface level, eliminating the need for digging while maintaining mole eradication effectiveness. The device can be inserted into existing mole holes without requiring extensive excavation of the lawn.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

A protective sleeve acts as an intermediary between the sharp killing mechanism and the external environment. The sleeve can be rotated to expose or conceal the sharp, providing a safe handling mechanism that eliminates the need for digging while maintaining effectiveness.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If traditional traps are installed by digging into the ground, then mole eradication effectiveness is improved, but lawn destruction increases

Engineering Contradiction:

Improvemole eradication effectivenessVSAvoidlawn destruction

Core Design Contradiction:

ReliabilityVSArea of stationary object

Solution Approach 1:

The killing mechanism is extracted from the in-ground installation requirement and repositioned to surface level, eliminating lawn destruction while maintaining effectiveness. The device utilizes existing mole holes rather than requiring new excavations.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The device is segmented into a removable protective sleeve and a fixed handle with sharp mechanism. This segmentation allows the sharp component to be concealed during storage and transport, and only exposed when actively used at the mole hole surface level.

Inventive Principle:

Principle #1Segmentation

3Reliability

If spring-loaded blade or snare traps are used, then mole killing effectiveness is improved, but safety hazards to children and pets increase

Engineering Contradiction:

Improvemole killing effectivenessVSAvoidsafety hazards

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

A rotatable protective sleeve serves as an intermediary between the sharp killing mechanism and users. The sleeve can be rotated to conceal the sharp during storage and transport, eliminating safety hazards to children and pets while maintaining killing effectiveness when deployed.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The protective sleeve is designed to be dynamically rotatable, transitioning between a concealed safe state during storage and an exposed effective state during use. This dynamic protection mechanism eliminates safety hazards while preserving functionality.

Inventive Principle:

Principle #15Dynamics

4Object-affected harmful factors

If live traps are used, then safety to children and pets is improved, but installation and retrieval complexity increase

Engineering Contradiction:

Improvesafety to children and petsVSAvoidinstallation and retrieval complexity

Core Design Contradiction:

Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The device extracts the lethal function from complex live trap mechanisms and implements it through a simple rotatable sleeve with sharp. This simplifies installation and retrieval while maintaining safety through proper design.

Inventive Principle:

Principle #2Taking out (Extraction)

5Device complexity

If above ground spear-type traps are used, then installation complexity is reduced, but safety hazards to children and pets increase

Engineering Contradiction:

Improveinstallation complexityVSAvoidsafety hazards

Core Design Contradiction:

Device complexityVSObject-affected harmful factors

Solution Approach 1:

A rotatable protective sleeve acts as an intermediary that conceals the sharp during storage and transport, eliminating safety hazards while maintaining the simple above-ground installation advantage. The sleeve is rotated to expose the sharp only when actively used at the mole hole.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The protective sleeve provides dynamic protection through rotation, transitioning from a concealed safe state during storage to an exposed effective state during use. This maintains the simplicity of above-ground installation while eliminating safety hazards.

Inventive Principle:

Principle #15Dynamics
