Solution Overview
Problem
Existing ground treatment apparatuses are inefficient for managing large grass surfaces, such as soccer fields, as they require manual guidance and are time-consuming, leading to uneven aeration.
Innovation Solution
A ground treatment apparatus with a support device, multiple injection elements, and a drive system that allows the injection elements to be lowered and raised, enabling them to move along a working direction, injecting fluid into the ground in a continuous manner without needing to stop, ensuring systematic and time-saving management of large areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual guidance and stop-and-inject operation is used, then the apparatus can be simple in structure, but the treatment of large ground surfaces becomes time-consuming and inefficient
Solution Approach 1:
The injection elements are made dynamically movable relative to the support device along the working direction through a drive device. This allows the injection elements to be advanced continuously or intermittently through the ground, enabling the apparatus to treat large ground surfaces efficiently without requiring manual repositioning or stopping, thus resolving the contradiction between treatment speed and device complexity
Solution Approach 2:
The drive device enables continuous or quasi-continuous movement of the injection elements through the ground in the working direction. This continuous action allows the apparatus to treat large ground surfaces without interruption, significantly improving productivity compared to manual stop-and-inject operations while maintaining manageable device complexity through automated drive mechanisms
2Reliability
If the apparatus is stopped for each injection, then the injection elements can be properly engaged in the ground, but the treatment of large areas becomes time-consuming
Solution Approach 1:
The drive device enables the injection elements to remain continuously engaged in the ground while being moved along the working direction. This continuous engagement eliminates the need to stop the apparatus for each injection, significantly reducing the time required to treat large areas while maintaining reliable injection engagement through sustained contact between the injection elements and the ground
Solution Approach 2:
The drive device preliminarily positions and engages the injection elements in the ground before fluid injection occurs. This preliminary engagement ensures that the injection elements are properly positioned and secured in the ground prior to injection, maintaining reliability while enabling continuous operation to reduce overall treatment time
3Ease of operation
If manual guidance is used, then the apparatus is easy to operate, but the aeration is not performed evenly across large surfaces
Solution Approach 1:
The manual guidance mechanism is replaced with a drive device that mechanically propels the injection elements through the ground along a defined working direction. This substitution eliminates the need for manual guidance while ensuring uniform aeration through consistent, mechanically controlled movement of the injection elements across the ground surface
Solution Approach 2:
The drive device provides dynamic, controlled movement of the injection elements through the ground, replacing static manual positioning. This dynamic system ensures uniform aeration by maintaining consistent engagement depth and movement speed, achieving precision in aeration patterns without requiring manual skill or attention
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
The apparatus allows for quasi-continuous treatment of large grass surfaces, improving soil aeration and drainage, promoting grass growth, and maintaining evenness, making it suitable for large sports facilities like soccer fields.
Implementation Method 1
A fluid is injected into the ground through the injection elements. The action of the fluid, in particular a compressed gas or compressed gas mixture, can loosen the soil of the ground.

AI summary
A ground treatment apparatus comprises a support device, injection elements, a fluid providing device that is fluidically connected to the injection elements, a drive device by which the injection elements are on the one hand lowerable and raisable in relation to the support device and on the other movable along a working direction of the ground treatment apparatus. The injection elements are insertable into the ground by being lowered in order to inject fluid into the ground in a treatment region, wherein the injection elements remain stationary during engagement in the ground in the treatment region, with relative movement in relation to the support device that is moved in the working direction, wherein the injection elements are raisable after the injection of fluid and are movable in the working direction in relation to the support device, wherein, on being lowered again, the injection elements are insertable into the ground in a further treatment region that is downstream of the first-mentioned treatment region, as seen in the working direction.
