Rodent Trap Indicator Mechanism for Hazard-Free Monitoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional rodent traps, such as snap traps and chemical rodenticides, face challenges in efficiently indicating rodent presence without physical inspection, particularly in large areas like food processing plants, where manual checking is time-consuming and exposes personnel to potential hazards.
Innovation Solution
A rodent trap with a visible presence indicator mechanism, featuring a hinged cover, a spring-loaded killing device, and an indicator device that activates upon trap triggering, allowing for easy monitoring of rodent activity without exposing the dead rodent, and incorporating a low-profile design with separate entrance and exit points to attract rodents effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual inspection of each trap is performed to check for rodent activity, then accurate detection of rodent presence is achieved, but time consumption increases significantly
Solution Approach 1:
The trap system performs self-monitoring through an indicator mechanism that automatically detects and displays rodent presence without requiring operator inspection. The indicator device changes state based on trigger activation, allowing the system to serve its own monitoring function.
Solution Approach 2:
An indicator device serves as an intermediary between the trap trigger mechanism and the operator. Instead of directly observing the trap interior, the operator observes the indicator which conveys information about rodent presence, eliminating the need for physical inspection.
2Reliability
If manual inspection of traps is performed frequently to ensure accurate detection, then rodent presence is accurately monitored, but productivity decreases due to time consumption
Solution Approach 1:
The indicator device provides immediate visual feedback about trap activation status. When the trigger is activated by a rodent, the indicator automatically changes state to signal the operator, creating a closed-loop feedback system that eliminates the need for proactive inspection.
Solution Approach 2:
The monitoring function is transferred from the operator to the trap system itself. The indicator mechanism autonomously tracks and communicates rodent presence, allowing operators to focus on servicing rather than inspection.
3Measurement precision
If physical inspection of trap interior is conducted to verify rodent capture, then accurate confirmation of rodent presence is achieved, but exposure to hazards increases
Solution Approach 1:
The indicator device acts as an intermediary that conveys information about rodent capture without requiring direct observation of the trap interior. The operator receives information about rodent presence through the indicator rather than through direct inspection, eliminating exposure to hazards.
Solution Approach 2:
The indicator device creates a visual copy or representation of the trap's internal state (trigger activation). Instead of observing the actual rodent or trigger mechanism inside the trap, the operator observes the indicator which replicates the information about activation status.

AI summary
A rodent station includes a base with an entrance point and an exit point to allow a rodent to access the station. A hinged cover may be coupled to the base for housing an indicator device. The indicator device may be configured to show an operator that activity, such as capturing a rodent, has occurred within the rodent station. A killing device may be disposed in the base and configured to activate the indicator device upon being triggered by a rodent. The killing device may include an arm that rotates when triggered by the rodent. In one exemplary embodiment, a portion of the arm may contact a portion of the indicator device, resulting in an alert portion protruding from the cover of the rodent station, thereby indicating the triggering of the killing device. The indicator device may be, for example, a spring-loaded pop-up device or a rotating flag device.
