Solution Overview

Problem

Current rat catching methods, including chemical and physical methods, face issues such as human and livestock safety concerns, pollution, inefficiency, and the inability to continuously kill rats on a large scale, with existing high-voltage equipment being unsafe, inconvenient, and limited in functionality.

Innovation Solution

A rat catching box with a trap opening and recovery opening, featuring a lifting platform, a control assembly with a voltage measurement module, high-voltage transformer, and densely arranged power grid lines on a rat catching platform, which generates a triggering signal when a rat connects the lines, allowing for high-voltage electric shock and automatic recovery.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If chemical deratization methods are used, then deratization can be performed economically on a large scale, but it poses a threat to human and livestock safety and causes pollution

Engineering Contradiction:
Improvederatization efficiencyVSAvoidsafety and pollution
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The patent replaces chemical deratization methods with a physical electrical shock system. A high-voltage transformer generates electric current that flows through power grid lines arranged on the rat catching platform. When a rat contacts these lines, it receives a lethal electric shock, eliminating the need for poisonous chemicals while maintaining large-scale deratization capability

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

Solution Approach 2:

The patent converts the rat's natural behavior of seeking food (bait) into its detriment. The bait is placed on the power grid lines, attracting rats to contact the electrified lines. The very act of the rat approaching the bait becomes the mechanism of its own elimination through electrical shock

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

2Object-affected harmful factors

If physical deratization methods such as rat cages or traps are used, then human safety is ensured, but they cannot be used on a large scale and cannot kill rats in a timely manner

Engineering Contradiction:
ImprovesafetyVSAvoidderatization efficiency
Core Design Contradiction:
Object-affected harmful factorsVSProductivity

Solution Approach 1:

The patent implements continuous deratization capability through an automated system. The high-voltage transformer and control circuitry enable the system to operate continuously without manual intervention. Multiple rats can be eliminated in sequence as they contact the power grid lines, unlike single-use traps that require manual collection and resetting

Inventive Principle:
Principle #20Continuity of useful action

Solution Approach 2:

The patent creates a multi-functional integrated system that combines trapping, killing, and recovery functions in one device. The box body with trap opening captures rats, the power grid lines eliminate them through electrical shock, and the recovery opening allows for easy removal of dead rats, replacing multiple separate devices

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Object-affected harmful factors

If existing high-voltage power line deratization equipment is used, then rats can be killed electrically, but the equipment can only be placed once and kill one rat at a time, cannot work continuously

Engineering Contradiction:
Improverat elimination capabilityVSAvoidcontinuous operation capability
Core Design Contradiction:
Object-affected harmful factorsVSProductivity

Solution Approach 1:

The patent implements continuous deratization capability through an automated system. The high-voltage transformer and control circuitry enable the system to operate continuously without manual intervention. Multiple rats can be eliminated in sequence as they contact the power grid lines, unlike single-use traps that require manual collection and resetting

Inventive Principle:
Principle #20Continuity of useful action

Solution Approach 2:

The patent enables the system to reset and operate automatically without human intervention. After a rat is eliminated, the power grid lines remain energized and ready for the next rat. The control assembly automatically manages the high-voltage output, allowing the system to serve itself continuously rather than requiring manual repositioning or resetting

Inventive Principle:
Principle #25Self-service

4Object-affected harmful factors

If existing high-voltage power line deratization equipment is used, then electrical killing is achieved, but the equipment has single function and is difficult to recover the dead rats

Engineering Contradiction:
Improverat elimination capabilityVSAvoidfunctional integration
Core Design Contradiction:
Object-affected harmful factorsVSAdaptability or versatility

Solution Approach 1:

The patent creates a multi-functional integrated system that combines trapping, killing, and recovery functions in one device. The box body with trap opening captures rats, the power grid lines eliminate them through electrical shock, and the recovery opening allows for easy removal of dead rats, replacing multiple separate devices

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent merges three separate functions (trapping, killing, and recovery) into a single integrated device. The box body structure combines the trapping mechanism with the electrical killing system and the recovery opening, creating a unified multi-functional device rather than separate components

Inventive Principle:
Principle #5Merging (Combining)

AI summary

A rat catching box includes a box body, a lifting platform, and a control assembly. The box body is provided with a trap opening and a recovery opening. The lifting platform is disposed at the bottom of the box body, and a rat catching platform parallel to the lifting platform is disposed above the lifting platform. The control assembly is disposed on the box body, and includes a voltage measurement module, a controller, a high-voltage transformer, and a power grid. The voltage measurement module transmits a triggering signal of the power grid to the controller, and the controller controls the high-voltage transformer to supply power to the power grid. The power grid includes a positive power grid line and a negative power grid line. The negative power grid line in disconnection is divided into three segments connected respectively to a negative electrode of the high-voltage transformer.
