Solution Overview

Problem

Conventional rodent traps are ineffective against wary rodents, such as larger mice, as they require the rodent to step into or onto the trap, allowing smaller mice to be caught while larger breeding mice evade extermination.

Innovation Solution

A motion-sensing rodent extermination device with a housing and a ram that crushes the rodent between the ram and an oppositely facing surface, activated by a motion sensor, eliminating the need for the rodent to see or step into a trap, effectively targeting larger mice.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional traps are used, then smaller mice can be captured, but larger breeding mice evade extermination because they are wary and avoid traps they can see

Engineering Contradiction:
Improveextermination effectivenessVSAvoidrodent wariness
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent introduces a motion-activated ram as an intermediary mechanism between detection and killing. The ram remains hidden until activated by motion detection, serving as an unseen mediator that delivers the lethal force without the rodent needing to interact with or see the trapping mechanism, thereby overcoming rodent wariness while ensuring reliable extermination

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces traditional mechanical trap systems (springs, bars, cages) with a motion-activated ram system. This substitution eliminates the need for rodents to trigger visible mechanical components, as the ram is activated by motion sensors and delivers a swift, unseen strike, thereby maintaining effectiveness against wary rodents

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Force

If the ram is deployed with sufficient force to crush the rodent, then larger mice can be killed, but the device may produce noise that could alert remaining rodents

Engineering Contradiction:
Improvecrushing forceVSAvoidnoise
Core Design Contradiction:
ForceVSObject-generated harmful factors

Solution Approach 1:

The patent applies local quality by positioning sound-absorbing materials specifically at the impact zone where the rodent is crushed. This localized application of noise reduction properties allows the ram to deploy with sufficient crushing force to kill larger rodents while minimizing the noise generated at the specific location of impact, thereby balancing lethal force with noise reduction

Inventive Principle:
Principle #3Local quality

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

The device provides a stealthy and effective means of eliminating larger mice by deploying a ram with sufficient force to crush the rodent, ensuring that breeding mice are targeted and eliminated, while minimizing sound and visibility to avoid detection.

Implementation Method 1

A motion sensor is mounted on the housing and is directed outwardly away from the front wall

AI summary

A motion sensing rodent killing apparatus includes a housing that has a bottom wall and a perimeter wall. The perimeter wall includes a front wall. A motion sensor is directed outwardly away from the front wall. A ram is mounted on the housing and is movable toward or away from the front wall. A driving system is mounted to the housing and is engaged with the ram. The driving system retains the ram in a set position having the panel positioned adjacent to the front wall. When the motion sensor detects motion, the driving system drives the panel away from the housing to a deployed position with sufficient force such that a rodent positioned between the panel and a facing surface is killed by the panel.
