Solution Overview

Problem

Existing methods for controlling ground mole tunneling are ineffective in eliminating moles and their tunnels without using harmful chemicals or dangerous traps, and there is a lack of efficient solutions in this field.

Innovation Solution

A device comprising a wheel with spiked protrusions, a center hub, and a handle, manufactured from various materials, which is aligned with ground mole tunnels and manually propelled to impale and eliminate ground moles, thereby reducing tunneling activity.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If harmful chemicals or dangerous traps are used to control ground moles, then mole tunneling is suppressed, but environmental safety and user safety deteriorate

Engineering Contradiction:

Improvemole tunnelingVSAvoidchemical harm and trap danger

Core Design Contradiction:

Object-affected harmful factorsVSObject-generated harmful factors

Solution Approach 1:

The invention converts the mole's natural behavior of tunneling through soft ground into its detriment by introducing spiked protrusions that inflict harm when the mole attempts to tunnel. The spikes penetrate and impale the mole during its tunneling activity, transforming the mole's own tunneling behavior from a beneficial activity (aeration of soil) into a harmful process that eliminates the pest without chemicals or dangerous traps.

Inventive Principle:

Principle #22Blessing in disguise (Convert harm into benefit)

2Object-affected harmful factors

If conventional mole control methods are used, then some level of mole suppression is achieved, but effectiveness in eliminating moles and tunnels is insufficient

Engineering Contradiction:

Improvemole tunnelingVSAvoidelimination effectiveness

Core Design Contradiction:

Object-affected harmful factorsVSReliability

Solution Approach 1:

The invention replaces ineffective mechanical mole control systems (such as shallow barriers or non-penetrating devices) with a highly effective mechanical system featuring spiked protrusions that actively penetrate and impale moles. The spikes are specifically designed with sufficient length and sharpness to reliably penetrate mole skin and tissue, ensuring certain elimination rather than mere suppression.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Ease of manufacture

If a simple wheel design is used, then manufacturing ease is improved, but effectiveness in mole elimination deteriorates

Engineering Contradiction:

Improvewheel constructionVSAvoidmole tunneling control

Core Design Contradiction:

Ease of manufactureVSObject-affected harmful factors

Solution Approach 1:

The invention applies local quality by concentrating the anti-mole function in the spiked protrusions attached to the wheel rim, while the wheel itself maintains a simple, easy-to-manufacture structure. The spikes are the specialized component that provides effective mole elimination, while the wheel body remains a basic circular form that can be easily manufactured from common materials, thus resolving the contradiction between simplicity and effectiveness.
