Solution Overview

Problem

Existing construction systems, such as building blocks and fences, are inefficient in terms of installation speed and require time-consuming assembly steps, particularly when using plates that do not provide adequate ground support.

Innovation Solution

A construction system utilizing connecting plates that are less bulky and lighter than traditional blocks, allowing for easier handling and installation, with improved ground support through rear wedging and interlocking mechanisms, reducing the number of blocks needed for a given surface area.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If connecting plates are used instead of traditional blocks, then installation speed and ease of handling are improved, but ground support and structural stability may be compromised

Engineering Contradiction:
Improveinstallation speedVSAvoidground support
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The construction system segments the wall into alternating blocks and connecting plates, where blocks provide ground support and plates enable quick installation. This segmentation allows each component to fulfill its specific function optimally.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Connecting plates act as intermediary elements between blocks, providing a lightweight alternative for portions of the wall while maintaining structural continuity. The plates mediate between the need for quick installation and the requirement for stability.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Weight of moving object

If fewer blocks are used with more connecting plates, then the number of heavy components is reduced, but the structural integrity may be weakened

Engineering Contradiction:
Improvecomponent weightVSAvoidstructural integrity
Core Design Contradiction:
Weight of moving objectVSStrength

Solution Approach 1:

The system merges the advantages of blocks (ground support, stability) with the advantages of plates (lightweight, easy installation) into a hybrid construction system. This combination achieves both weight reduction and structural integrity.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

Different components are assigned different local qualities: blocks have large base areas for ground support where needed, while plates have reduced dimensions for lightweight construction in other portions. This local differentiation optimizes both weight and strength.

Inventive Principle:
Principle #3Local quality

3Ease of operation

If connecting plates with reduced dimensions are used, then handling and installation become easier, but the number of connection points increases

Engineering Contradiction:
Improvehandling easeVSAvoidnumber of connection points
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The connecting plates are designed to be self-aligning and self-securing through their specific geometry and connection mechanisms, reducing the skill level and time required for installation despite the increased number of connection points.

Inventive Principle:
Principle #25Self-service

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 system enables faster wall construction with enhanced stability and reduced vertical settlement, leveraging the advantages of both blocks and plates to optimize installation efficiency and structural integrity.

Implementation Method 1

During support, the mass of backfill allows the plate to be wedged against the first walls of the blocks, by exerting pressure from the rear of the plate
