Vibrating Soil Plate Penetration for Chemical-Free Grub Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for controlling cockchafer grubs in soil are ineffective due to their underground location and the harmful effects of chemical pesticides on other soil-dwelling animals, with existing solutions failing to address the root damage caused by these pests.
Innovation Solution
A device featuring a vibration plate with penetrating elements, such as triangular knives made of Hardox steel, that moves up and down to penetrate the soil and kill pests, while also aerating and loosening the soil, and can be coupled with fertilizers and seed spreaders for integrated soil management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If chemical-synthetic preparations are used to control cockchafer grubs, then pest control effectiveness is improved, but harmful effects on other soil-dwelling animals increase
Solution Approach 1:
The patent replaces chemical-synthetic preparations with a mechanical system consisting of a vibration plate and penetrating elements that physically kill cockchafer grubs through high-frequency vibrations and mechanical penetration, eliminating the harmful chemical effects on other soil-dwelling animals while maintaining pest control effectiveness
Solution Approach 2:
The patent changes the control parameter from chemical concentration to mechanical vibration frequency and penetration depth, using adjustable vibration frequencies (50-50,000 Hz) and controlled penetration element depths to selectively target cockchafer grubs at specific soil depths while sparing other organisms
2Area of stationary object
If penetrating elements are made longer to reach deeper pests, then pest control coverage is improved, but soil disturbance increases
Solution Approach 1:
The patent employs penetrating elements with adjustable and variable lengths that can be dynamically adapted to different pest infestation depths, allowing the system to reach deeper pests when necessary while minimizing soil disturbance through selective deployment of penetration depth rather than using uniformly long elements for all cases
3Reliability
If vibration frequency is increased to improve pest killing effectiveness, then energy consumption increases
Solution Approach 1:
The patent utilizes periodic high-frequency vibrations (50-50,000 Hz) that are applied in controlled cycles rather than continuous operation, allowing the vibration plate to accumulate effective vibration energy for pest killing while periodic interruption reduces overall energy consumption and allows for thermal management of the drive motor
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Effectively kills cockchafer grubs and improves soil health through mechanical means, minimizing environmental impact and promoting plant growth by using high-frequency vibrations and adjustable penetrating elements, while allowing for selective sparing of deeper organisms.
Implementation Method 1
at least one vibration plate (3) which can be moved up and down by means of a drive motor (5) and which exerts pressure on the soil (2) to be processed
Implementation Method 2
The vibration plate is advantageously pressed onto the soil to be worked with a pressure of up to 160 kN. The high pressure exerted by the vibration plate on the ground also kills pests - even without the penetrating elements penetrating the ground - by causing them to burst due to the high pressure
