Solution Overview

Problem

Traditional rat and mouse traps pose a risk of accidental triggering by larger pets, children, or adults due to the ease with which they can activate the killing mechanism with their paws or hands.

Innovation Solution

A poison-free trap design featuring a housing with a rat and mouse entry opening lined with serrated protrusions, positioning the killing device above the entry point to deter larger intruders and incorporating a secure configuration that allows rodents to enter safely while preventing human access, including a gas cartridge-operated killing mechanism and wireless activation signaling.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the killing means is positioned within easy reach of the entry opening, then rodents can easily trigger it, but larger pets or children can accidentally trigger it with their paws or hands

Engineering Contradiction:
Improvekilling efficiencyVSAvoidaccidental triggering risk
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The killing means is positioned vertically above the entry opening rather than horizontally adjacent to it. This vertical displacement creates a spatial separation that prevents accidental triggering by paws or hands entering through the opening, while still allowing rodents to contact the killing means by standing on their hind legs inside the housing

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The entry opening is lined with serrated protrusions at specific locations to create a localized deterrent effect. These serrations are positioned only at the entry point where larger animals or children might place their paws or hands, providing selective protection without affecting rodent access to the killing means

Inventive Principle:
Principle #3Local quality

2Object-affected harmful factors

If the entry opening is made narrow to prevent larger animals from reaching the killing means, then accidental triggering is reduced, but rodents may have difficulty entering

Engineering Contradiction:
Improveaccidental triggering riskVSAvoidrodent entry ease
Core Design Contradiction:
Object-affected harmful factorsVSEase of operation

Solution Approach 1:

Instead of reducing the horizontal dimensions of the entry opening, the solution positions the killing means in the vertical dimension above the opening. This maintains a generous horizontal opening size that is easily accessible to rodents while preventing accidental triggering through vertical spacing

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Object-affected harmful factors

If the killing means is positioned high above the entry opening, then accidental triggering by larger animals or children is prevented, but rodents may have difficulty reaching it

Engineering Contradiction:
Improveaccidental triggering riskVSAvoidkilling efficiency
Core Design Contradiction:
Object-affected harmful factorsVSProductivity

Solution Approach 1:

The vertical height of the killing means above the entry opening is optimized to a specific parameter range that accommodates rodent anatomy and behavior. Rodents can stand on their hind legs inside the housing to reach the killing means, while the exact height positioning ensures that even when extended, their paws cannot accidentally trigger it during normal entry movements

Inventive Principle:
Principle #35Parameter changes
