Rodent Trap Sensor Module for Remote Activation Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current rodent traps lack efficient electronic detection and communication systems to reliably monitor trap activation and distinguish between actual rodent captures and other environmental stresses, requiring manual inspection by Pest Control Operators.
Innovation Solution
A rodent trap with a pivotably mounted upper jaw and spring mechanism, integrated with a sensor module containing a SW-18010P omnidirectional vibration/acceleration sensor and a Bluetooth transceiver/microcontroller, which detects trap activation and sends a signal via Bluetooth, allowing remote monitoring and differentiation from other environmental forces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual inspection of rodent traps is used, then Pest Control Operators can determine infestation sources and frequency, but it requires significant time and labor effort
Solution Approach 1:
The patent replaces manual mechanical inspection with electronic sensing systems. Vibration sensors, acceleration sensors, and tilt sensors automatically detect trap activations and transmit data remotely, eliminating the need for Pest Control Operators to physically inspect each trap while maintaining reliable detection of actual rodent captures.
2Extent of automation
If electronic sensors are added to detect trap activation, then remote monitoring is enabled, but it becomes difficult to distinguish between actual rodent captures and environmental stresses
Solution Approach 1:
The patent divides the detection function into multiple specialized sensors: vibration sensors for impact detection, acceleration sensors for motion detection, and tilt sensors for position change detection. Each sensor type detects different aspects of trap activation, and their combined data allows the system to distinguish genuine rodent captures from environmental stresses like wind or accidental bumps.
Solution Approach 2:
The system continuously monitors sensor data and provides feedback to distinguish true activations from false signals. By analyzing patterns in vibration, acceleration, and tilt data over time, the system can differentiate between the specific signature of a rodent triggering the trap versus random environmental disturbances.
3Measurement precision
If multiple sensors are integrated into the trap, then accurate detection of rodent captures is achieved, but the device complexity increases
Solution Approach 1:
The patent uses a multi-functional microcontroller unit that handles data acquisition from multiple sensor types, signal processing, data storage, and wireless communication. This single integrated component performs multiple functions, reducing the need for separate dedicated circuits for each function and thereby managing device complexity while maintaining high detection accuracy.

Function Achieved in This Case
Enables remote supervision and maintenance of trap placements, reducing manual effort and ensuring accurate detection of trap activations, thereby improving the efficiency and reliability of rodent control operations.
Implementation Method 1
The Sensor module includes a SW-18010P, a spring based omnidirectional vibration/acceleration sensor which is normally off, but is momentarily on when triggered, which detects closure of the trap
Implementation Method 2
The Sensor module includes a SW-18010P, a spring based omnidirectional vibration/acceleration sensor which is normally off, but is momentarily on when triggered, which detects closure of the trap
Implementation Method 3
An alternative type sensor is a Hall effect device which senses a magnetic field generated by a magnet mounted to a portion of the trap e.g., the trap trigger, which moves relative to the trap base when the trap is triggered and closes
Data Source
AI summary
A mechanical rodent trap has a jaw mounted to a base, with a trigger therebetween which is activated by the incidence of a rodent. An acceleration sensor is mounted in a case in the base in a sensor module that logs and transmit a signal indicating activation of the trap. Alternatively a magnet holder secures a magnet to the trigger, and a Hall effect sensor is used in the sensor module. The sensor modules are sealed within a compartment formed with the base beneath the trigger and closed by a cover.
