Solution Overview

Problem

Existing mole eradication methods and apparatuses are mechanically complex, unreliable, and often cause inhumane injury to moles without immediate death, leading to prolonged suffering.

Innovation Solution

A mechanically simple apparatus with a shaft, T-handle, U-bracket, step plate, and lances, combined with friction ridges or snaring barbs, allows for precise and humane mole extraction by piercing and extracting moles from the ground.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If known apparatus and methods are used for lancing moles, then mole eradication is attempted, but the apparatus becomes mechanically complex and unreliable

Engineering Contradiction:

Improvemole eradication reliabilityVSAvoidapparatus mechanical complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The apparatus is divided into distinct functional components: a handle assembly, a shaft, and multiple lances with independent triggering mechanisms. Each component performs a specific function, allowing for simplified design of individual parts while maintaining overall system effectiveness for reliable mole eradication.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Instead of using a single complex lance mechanism, the invention uses multiple simple lances arranged in an array. The inversion is in approaching the problem from multiple angles (multiple lances) rather than one complex angle, thereby simplifying each individual component while achieving reliable eradication through redundancy.

Inventive Principle:

Principle #13The other way round (Inversion)

2Object-affected harmful factors

If known apparatus injure moles without killing them, then mole eradication is attempted, but the moles suffer prolonged inhumane death

Engineering Contradiction:

Improvemole sufferingVSAvoidinstant death reliability

Core Design Contradiction:

Object-affected harmful factorsVSReliability

Solution Approach 1:

Multiple lances are combined into a single apparatus that delivers multiple piercing actions simultaneously or in rapid succession. This merging of multiple simple piercing elements creates a cumulative effect that ensures immediate death by disrupting critical bodily functions, eliminating prolonged suffering.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The apparatus is designed to deliver continuous piercing action through multiple lances that can strike in sequence or simultaneously. This continuity ensures that the mole receives sufficient trauma to die immediately rather than suffering a prolonged death from a single injurious puncture.

Inventive Principle:

Principle #20Continuity of useful action
