Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ultrasonic animal repelling devices struggle to effectively propagate sound waves in soil due to the soil's composition of air, water, and sediment, limiting their ability to repel animals underground.
Innovation Solution
The device generates longitudinal waves by arranging tabs on the insertion end of the rod, allowing the waves to propagate in solid, liquid, and gas mixtures, enhancing the propagation range and stability in soil.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If shear waves are used to repel animals under the ground, then the device structure is simple, but the propagation ability is rapidly reduced in soil
Solution Approach 1:
The insertion rod is segmented into multiple tabs extending at different angles from the center line. Each tab acts as an independent vibration element that generates longitudinal waves, dividing the single vibration source into multiple directional sources to improve propagation in complex soil media.
Solution Approach 2:
The invention changes the wave type parameter from shear wave to longitudinal wave by modifying the vibration direction of the insertion rod. Longitudinal waves can propagate through solid, liquid, and gas phases, making them suitable for the complex soil environment that contains air, water, and sediment mixtures.
2Reliability
If longitudinal waves are generated by tabs at angles to the center line, then the propagation range in soil is expanded, but the device structure becomes more complex
Solution Approach 1:
The tabs serve multiple functions: they act as vibration elements to generate longitudinal waves, provide structural reinforcement to the insertion rod, and create directional wave propagation patterns. This multi-functionality reduces the need for additional components while achieving the propagation goal.
Solution Approach 2:
The tabs extend in multiple dimensions at different angles from the center line, creating a three-dimensional vibration pattern. This dimensional approach allows the device to propagate waves in various directions simultaneously, expanding coverage without requiring multiple separate devices.
3Ease of operation
If the insertion rod vibrates left and right to generate sound waves, then the device operation is simple, but only shear waves are produced which cannot propagate effectively in soil
Solution Approach 1:
The insertion rod is designed to vibrate dynamically in multiple directions rather than a fixed single direction. The tabs at different angles enable the rod to generate longitudinal waves that can adapt to the complex, heterogeneous soil medium, improving propagation effectiveness while maintaining operational simplicity.

Implementation Method 2
it will drive the tab to vibrate left and right, thus forming a longitudinal wave with the same propagation direction as the tab vibration direction
Implementation Method 3
when the insertion rod vibrates left and right, it will drive the tab to vibrate left and right
Implementation Method 4
forming a longitudinal wave with the same propagation direction as the tab vibration direction. As the longitudinal wave is generated when the medium is subjected to alternating tensile and compressive stress
