Solution Overview

Problem

Conventional rodent traps pose risks of accidental injury to humans and fail to effectively capture rodents due to escape mechanisms, and battery-powered traps are not feasible for long-term standby modes.

Innovation Solution

A rodent trap featuring a cage with discharge plates and infrared sensors that activate a high voltage only when a rodent steps on the plates, preventing accidental activation and ensuring capture by blocking infrared beams, with a control circuit board managing the voltage and sensors to ensure safe and effective trapping.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If high voltage is always applied to discharge plates for effective rodent capture, then trapping effectiveness is improved, but risk of accidental human injury increases

Engineering Contradiction:
Improvetrapping effectivenessVSAvoidrisk of human injury
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The control circuit board activates the high voltage supply to discharge plates only after detecting rodent presence through infrared sensors. The infrared emitter and receiver establish a detection beam, and when blocked by a rodent, the control circuit triggers high voltage activation. This preliminary detection action ensures high voltage is applied only when needed, preventing accidental human injury while maintaining trapping effectiveness.

Inventive Principle:
Principle #10Preliminary action

2Measurement precision

If infrared sensors are activated continuously for accurate rodent detection, then detection accuracy is improved, but energy consumption increases

Engineering Contradiction:
Improverodent detection accuracyVSAvoidenergy consumption
Core Design Contradiction:
Measurement precisionVSUse of energy by moving object

Solution Approach 1:

The infrared sensors are activated periodically rather than continuously. The control circuit board triggers the infrared emitter and receiver to operate only when rodent presence is suspected or at scheduled intervals. This periodic activation maintains detection accuracy for triggering high voltage while significantly reducing energy consumption during long standby periods.

Inventive Principle:
Principle #19Periodic action
