Solution Overview

Problem

Existing devices for driving elongate elements into the ground, such as piles and sheet piles, face challenges in achieving effective soundproofing while maintaining ease of operation and simple construction, as traditional soundproofing methods complicate the handling of elongate elements.

Innovation Solution

A soundproofing device composed of telescopically movable shell-shaped elements with stop means and drive mechanisms, including a cable pull system, allows for optimal noise insulation and easy handling by limiting the travel path of the shell-shaped elements and providing a stable, self-supporting structure.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If traditional soundproofing walls are arranged around the leader, then sound insulation is improved, but handling of elongate elements becomes difficult

Engineering Contradiction:
Improvenoise emissionsVSAvoidhandling of elongate elements
Core Design Contradiction:
Object-affected harmful factorsVSEase of operation

Solution Approach 1:

The soundproofing device is divided into multiple telescopic shell-shaped elements that can be segmented and moved independently. These elements form a chimney-like structure around the leader, allowing the soundproofing function to be maintained while providing openings for inserting elongate elements.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The soundproofing structure is made dynamic through telescopic movement. The shell-shaped elements can extend and retract along the leader, transforming from a closed soundproofing enclosure to an open configuration that facilitates easy insertion of elongate elements.

Inventive Principle:
Principle #15Dynamics

2Object-affected harmful factors

If a soundproof chimney with door elements is used, then sound insulation is improved, but construction complexity increases

Engineering Contradiction:
Improvenoise emissionsVSAvoidconstruction of soundproofing chimney
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

Multiple shell-shaped elements are nested within each other in a telescopic arrangement. Each shell element contains the next smaller shell element, creating a compact nested structure that simplifies the overall construction while maintaining soundproofing functionality.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The soundproofing structure utilizes the vertical dimension along the leader for telescopic movement, rather than requiring horizontal door openings. This dimensional approach simplifies the construction by eliminating complex door mechanisms while maintaining accessibility.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Ease of operation

If shell-shaped elements are moved telescopically, then ease of operation is improved, but device complexity increases

Engineering Contradiction:
Improveinsertion of elongate elementsVSAvoidtelescopic mechanism
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The telescopic shell elements are equipped with self-aligning features including guide means with rollers and stop means with projections. These self-service mechanisms automatically guide the telescopic movement and limit travel paths without requiring complex external control systems.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The complex mechanical door opening mechanisms are replaced with a simpler telescopic expansion system. The shell elements simply extend and retract along the leader using guide rollers and stop projections, substituting a straightforward mechanical telescoping action for complex door mechanisms.

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

AI summary

A device for inserting elongated elements into the ground comprises a piling (1) attached to a transport device (2). A device (3) for driving the elongated element is guided along the piling (1) and is provided with a sound-dampening device (4) which at least partially encloses the device (3) for driving the elongated element. The sound-dampening device (4) is formed from several shell-shaped elements (5) that are telescopically extendable into and out of each other, and the respective relative travel of the shell-shaped elements is limited by stop means. The uppermost shell-shaped element (5) in the extended position is fixed to the device (3) for driving the elongated element, and drive means are provided for moving the shell-shaped elements (5).This allows for optimal noise insulation and good usability of the equipment.
