Solution Overview

Problem

Conventional dry setting installations for underwater structures, such as sheet pile walls, are not adaptable to different steel sheet profiles, requiring multiple installations and being time-consuming and labor-intensive to manufacture and adjust for varying wall profiles, leading to increased material and construction costs.

Innovation Solution

An adjustable dry setting installation with varying distance and positioning means between side edge sealing elements, allowing the installation to fit different types of sheet pile walls by adjusting the width and position of the side walls and bottom, enabling reuse across multiple profiles.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional dry setting installations are manufactured to fit a specific wall profile, then sealing effectiveness is improved, but adaptability to different profiles deteriorates

Engineering Contradiction:
Improvesealing effectivenessVSAvoidadaptability to different profiles
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The side wall is made adjustable through a positioning system with multiple predetermined positions, allowing the installation to dynamically adapt to different wall profiles while maintaining effective sealing contact

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

A single dry setting installation design can serve multiple wall profiles by adjusting the side wall position to different predetermined locations, eliminating the need for custom installations for each profile type

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If multiple dry setting installations are manufactured for different profiles, then adaptability to different profiles is improved, but device complexity and manufacturing time deteriorate

Engineering Contradiction:
Improveadaptability to different profilesVSAvoidnumber of installations required
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

One universal installation design with adjustable side wall positioning can replace multiple fixed-profile installations, reducing the total number of different installation types needed while maintaining compatibility with various wall profiles

Inventive Principle:
Principle #6Universality (Multi-functionality)
