Solution Overview

Problem

Existing methods for producing material columns in the ground, such as wet and dry tamping compaction, require significant amounts of flushing water and often result in contamination and high costs, with limited material conveying capacity and increased soil washing.

Innovation Solution

A vibrator arrangement with a lateral projection that assists in material transportation by acting as a mechanical shovel, allowing for increased material flow and reduced water usage, where the projection extends around the periphery and is designed to broaden towards the lower end, optionally with a conical or pyramidal geometry and segments that can be folded or retracted.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If wet tamping compaction method is used, then material can be transported to lower end of vibrator, but large amounts of flushing water are required and contamination is washed out to surface

Engineering Contradiction:

Improvematerial conveying capacityVSAvoidflushing water consumption

Core Design Contradiction:

ProductivityVSLoss of substance

Solution Approach 1:

The patent extracts and eliminates the flushing water component from the material transportation system. Instead of using water to convey material, the invention uses a mechanically conveying device (screw conveyor or chain conveyor) that operates independently of water, thereby removing the source of water consumption and contamination while maintaining material transportation capability

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent replaces the hydraulic/water-based material transportation system with a mechanical conveying system. The screw conveyor or chain conveyor uses mechanical force to transport material to the lower end of the vibrator, substituting the water flushing mechanism and eliminating the associated water consumption and environmental contamination issues

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Productivity

If conveying pipe is used in dry tamping compaction, then material can be transported, but equipment complexity and costs increase

Engineering Contradiction:

Improvematerial conveying capacityVSAvoidequipment complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The patent merges the material conveying function with the vibrator structure itself. The screw conveyor or chain conveyor is integrated directly into the vibrator body, combining two functions (vibration and material conveyance) into a single integrated device, thereby reducing overall equipment complexity and eliminating the need for separate conveying pipes

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The vibrator is designed to perform multiple functions: it provides vibration for compaction and simultaneously conveys material to the lower end using the integrated screw or chain conveyor. This multi-functional design eliminates the need for separate conveying equipment, reducing complexity while maintaining material transportation capability

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Productivity

If annular space is enlarged to accelerate material transportation, then material flow improves, but soil is washed out and flushing water requirement increases

Engineering Contradiction:

Improvematerial flow rateVSAvoidsoil washing out

Core Design Contradiction:

ProductivityVSObject-generated harmful factors

Solution Approach 1:

The patent replaces the water-dependent material conveyance mechanism with a mechanical conveyor system that operates independently of water and annular space enlargement. The screw or chain conveyor provides efficient material transportation without requiring increased annular space, thereby preventing soil washing out and eliminating the need for additional flushing water

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Function Achieved in This Case

This solution enhances material flow by over 50% and reduces flushing water requirements by half, allowing for the potential elimination of water and use of air or gas for 'flushing', thereby minimizing environmental impact and operational costs.

Implementation Method 1

During a downward movement of the vibrating body, the projection which extends at least in sections around the periphery and protrudes in a lateral direction presses a material situated in an annular space underneath the projection further depthwise
