Solution Overview

Problem

Existing modular wall structures face challenges in quickly and reliably constructing straight walls using prefabricated components, particularly with wall blocks that are difficult to align vertically and horizontally.

Innovation Solution

A wall system comprising structural elements connected by coordinated connection devices, including male and female V-shaped elements, allowing for overlapping assembly to ensure rapid and straight construction.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If wall blocks are used to construct walls quickly, then construction speed is improved, but alignment precision deteriorates

Engineering Contradiction:
Improveconstruction speedVSAvoidalignment precision
Core Design Contradiction:
ProductivityVSManufacturing precision

Solution Approach 1:

Connection elements serve as intermediaries between wall blocks, providing built-in alignment features that guide precise positioning while enabling rapid assembly. The connection elements mediate the joining process, ensuring both speed and precision are achieved simultaneously.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

Alignment features are pre-formed on the wall blocks and connection elements during manufacturing. Grooves, protrusions, and guiding surfaces are created in advance, eliminating the need for complex alignment operations during construction, thus maintaining both speed and precision.

Inventive Principle:
Principle #10Preliminary action

2Device complexity

If traditional connection methods are used for wall blocks, then assembly is simplified, but construction time increases

Engineering Contradiction:
Improveassembly simplicityVSAvoidconstruction time
Core Design Contradiction:
Device complexityVSLoss of time

Solution Approach 1:

The connection system is segmented into distinct components: wall blocks with integrated connection elements, separate joining mechanisms, and modular assembly units. This segmentation allows for standardized, rapid assembly while maintaining simplicity through repeated use of identical modular components.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The wall blocks and connection elements are designed to self-align and self-secure through their geometric features. The connection elements automatically guide positioning and lock into place without requiring complex external alignment tools or procedures, reducing both time and complexity.

Inventive Principle:
Principle #25Self-service
