Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional rodent traps are inefficient, hazardous, costly, and environmentally harmful due to manual operation, toxic baits, high maintenance, and unsafe handling, lacking automated killing, disposal, and multiple power sources, and exposing users and wildlife to risks.
Innovation Solution
A rodent disposal device with an electrocution mechanism that kills rodents humanely using electrically charged metal plates and a compression spring system, automatically resetting and disposing of the rodent without rebaiting, using solar, wall, or battery power, and keeping electrocuting elements inaccessible to users.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional spring-loaded traps are used, then rodent killing function is provided, but user safety is compromised due to exposed electrocuting elements and toxic baits
Solution Approach 1:
The patent introduces a cylindrical tube as an intermediary structure that confines the electrocuting elements and rodent interaction zone. This tube acts as a protective barrier, allowing the electrocution function to work effectively while preventing direct user contact with hazardous components. The tube is integrated with the base unit and positioned to guide the rodent into the killing zone without exposing users to risks.
Solution Approach 2:
The patent extracts the hazardous electrocuting elements and toxic bait functions from direct user interaction. The electrocuting elements are mounted on the interior diameter of the cylindrical tube at locations inaccessible to users, and the bait is placed in a first cap that users do not need to handle during operation. This separation removes the harmful factors from user contact while preserving the rodent control function.
2Productivity
If manual operation and monitoring of traps is required, then trap functionality is maintained, but time consumption and operational cost increase
Solution Approach 1:
The patent implements self-service through automated rodent disposal. After electrocution, the compression spring mechanism automatically propels the dead rodent out of the cylindrical tube and into a collection container without requiring user intervention. The system also includes self-resetting capabilities where the electrocuting elements are recharged automatically, eliminating the need for manual monitoring and resetting of each trap.
Solution Approach 2:
The patent prepares the disposal mechanism in advance by pre-positioning the compression spring and collection container. The electrocuting elements are pre-charged through the power supply system (solar panel, battery, or wall outlet). This preliminary preparation ensures that when a rodent is killed, the disposal action occurs automatically without requiring user presence or intervention at the moment of killing.
3Object-affected harmful factors
If toxic baits are used to attract rodents, then rodent attraction is effective, but environmental contamination and wildlife poisoning occur
Solution Approach 1:
The patent replaces the chemical bait attraction system with a mechanical/electrical system. Instead of using toxic substances to attract and kill rodents, the system uses electrocuting elements that deliver an electrical shock. The bait in the first cap serves only as an attractant to guide rodents into the cylindrical tube, not as a killing agent. This substitution eliminates environmental contamination from toxic baits while maintaining effective rodent attraction and killing.
4Productivity
If electrocuting elements are made accessible for rodent killing, then killing effectiveness is improved, but user safety is compromised
Solution Approach 1:
The patent uses a nested structure where the electrocuting elements are mounted on the interior diameter of the cylindrical tube, which is itself nested within the base unit housing. The electrocuting elements are positioned at locations that are inaccessible to users from the outside, effectively nesting the hazardous components within protective structures. This nested arrangement maintains killing effectiveness by allowing rodent contact with the electrocuting elements while preventing user access.

Implementation Method 1
The PCB is configured to apply a deadly high voltage electrical shock to the rodent when the rodent touches the thin metal plates
Implementation Method 2
a compression spring including a first end and a second end, wherein the compression spring is configured horizontally in the middle part of the cylindrical tube

AI summary
Disclosed is a cylindrical tube placed at the top unit and ramps positioned into grooves on the base unit, wherein the rodent climbs one of the ramps in forward or aft directions into first end of the tube. The device also includes electrically charged thin metal plates on interior diameter of the tube. A PCB is located in the base unit below the tube and connected with metal plates to apply electrical shock to the rodent when the rodent touches the metal plates. The device further includes an electric motor at the base unit. A compression spring is configured horizontally in the middle part of tube and held back by PCB in first position. Subsequent to applying electric shock, the PCB releases the line to move spring to second position to extrude the rodent by first spring cap, such that the rodent is pushed and projected away from the device.
