Solution Overview

Problem

Existing methods for creating piles in the ground often result in incomplete or incorrect pile formation due to insufficient or excessive pile mass, leading to contamination and increased cleaning efforts, especially when using concrete.

Innovation Solution

A soil cultivation device with a core tube that continuously detects the fill level of pile mass using sensors connected to a controller, allowing for precise control of the insertion and retraction of the soil cultivation tool to ensure a needs-based supply of pile mass, preventing underfilling or overfilling, and utilizing a detachable closure device for efficient pile mass distribution.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If pile mass is supplied without continuous monitoring, then the supply process is simple, but the pile formation becomes incomplete or incorrect due to insufficient pile mass

Engineering Contradiction:
Improvepile formation accuracyVSAvoidmonitoring system complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

A sensor is integrated into the core tube to continuously detect the fill level of pile mass and transmit this information to a control unit. The control unit processes the sensor signals and controls the supply of pile mass accordingly, ensuring precise pile formation by maintaining the correct relationship between pile mass supply and drill pipe retraction

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The manual or unmonitored pile mass supply process is replaced with an automated system using sensors and control units. The sensor detects the fill level and the control unit automatically regulates the supply, replacing mechanical estimation methods with electronic monitoring and control

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Object-affected harmful factors

If excessive pile mass is supplied, then the borehole is overfilled, but contamination and cleaning efforts increase

Engineering Contradiction:
Improvecontamination levelVSAvoidpile creation efficiency
Core Design Contradiction:
Object-affected harmful factorsVSProductivity

Solution Approach 1:

The sensor continuously monitors the fill level and provides feedback to the control unit, which stops or regulates the pile mass supply when the appropriate level is reached. This prevents overfilling and the associated contamination problems while maintaining efficient pile creation

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system uses automatic sensor-based control to regulate pile mass supply, eliminating the need for manual monitoring and intervention. The system serves itself by automatically detecting fill levels and adjusting supply accordingly, preventing both underfilling and overfilling

Inventive Principle:
Principle #25Self-service

3Loss of substance

If pile mass is not precisely controlled, then material waste occurs, but the supply control system becomes more complex

Engineering Contradiction:
Improvepile mass wasteVSAvoidcontrol system complexity
Core Design Contradiction:
Loss of substanceVSDevice complexity

Solution Approach 1:

The control unit receives continuous feedback from the sensor about the fill level and automatically adjusts the pile mass supply to match the exact requirements. This precise feedback control minimizes material waste by ensuring that only the necessary amount of pile mass is supplied, without requiring overly complex control systems

Inventive Principle:
Principle #23Feedback

AI summary

The invention relates to a method and a soil cultivation implement for creating a pile in the ground. A soil cultivation tool with a core tube is inserted into the ground, creating a hole. The core tube is filled with a pile material. At least when the soil cultivation tool is withdrawn from the ground, pile material is introduced into the hole via the core tube, forming the pile in the ground. According to the invention, the fill level of the pile material in the soil cultivation tool is detected by means of at least one sensor, which is connected to a control unit. The control unit regulates the insertion of the soil cultivation tool into the ground and/or its withdrawal from the ground, depending on the detected fill level.
