Acoustic Termite Probe for Early Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current termite detection methods are often late in identifying pest activity, require human intervention, and are prone to neglect or obstruction, failing to provide early warning for termite attacks on structures.
Innovation Solution
A pest detection system comprising a pest attraction means, a sensor to receive sounds, a processor to analyze and detect pest activity, and a wireless transmitter to send alerts, allowing for early detection and remote notification of termite presence, with a timber probe acting as a bait to attract termites and an acoustic sensor to identify their activity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If visual inspection probes are placed around structures, then pest presence can be detected, but human intervention is required and inspection is often delayed or neglected
Solution Approach 1:
The probe system performs self-monitoring through integrated acoustic sensors that continuously detect pest activity without requiring human inspection. The system automatically processes sounds, identifies pest patterns, and triggers alerts when thresholds are exceeded, eliminating the need for manual visual inspection while maintaining reliable pest detection.
Solution Approach 2:
The system replaces manual visual inspection with acoustic sensing and electronic signal processing. Microphones capture sound waves from pest activity, and digital signal processors analyze the audio patterns to identify pests, substituting the mechanical/visual inspection process with an automated acoustic-electronic system.
2Loss of time
If probes are placed in ground around structures, then early pest detection is possible, but probes become inaccessible or difficult to check over time
Solution Approach 1:
The probe system performs self-monitoring through integrated acoustic sensors that continuously detect pest activity without requiring human inspection. The system automatically processes sounds, identifies pest patterns, and triggers alerts when thresholds are exceeded, eliminating the need for manual visual inspection while maintaining reliable pest detection.
Solution Approach 2:
The system provides automatic feedback through wireless transmission of detection data to a remote location. When pest activity is detected, the system sends alerts containing probe location and detection details, enabling timely response without requiring physical access to ground-level probes.
3Measurement precision
If hand-held acoustic devices are used, then pest activity can be detected, but skilled personnel are required and usage is limited to post-attack detection
Solution Approach 1:
The detection system is segmented into distributed probe units, each containing simplified acoustic sensing and processing capabilities. Multiple low-complexity probes are deployed around the structure, each independently monitoring local pest activity, rather than relying on a single complex hand-held device requiring skilled operation.
Solution Approach 2:
Each probe unit contains integrated signal processing and autonomous decision-making capabilities. The probes automatically analyze acoustic data, compare it against predetermined thresholds, and trigger alerts without requiring skilled personnel interpretation, making the system accessible to untrained users while maintaining precise detection.

AI summary
A pest detector (1) for actively detecting pest activity within the environs of a structure. The pest detector includes a pest detection unit (2) that detects pest activity through the analysis of sounds of pest activity within a pest bait. The pest bait is typically timber or cellulose material (3). Upon detection of pest activity, a signal is sent to wireless transmitting device which transmits a radio frequency signal which includes data identifying the pest detector. Advantageously, the radio frequency is in the cellular radio frequency spectrum and is transmitted via the cellular radio network to a remote base station. The signal can be in the form of a short message service message. In this way, the pest detector can be remotely monitored and any pest activity dealt with appropriately. The pest detector can be used within a pest detection system and the pest detection unit can be retrofitted to known pest monitoring systems.
