Solution Overview

Problem

Existing wall construction methods fail to provide a system that is easily disassemblable for reuse while meeting building physics and energetic requirements, and they often rely on screws for assembly and stability, which complicates construction and deconstruction.

Innovation Solution

A wall block system comprising interlocking wall blocks with multiple sets of cross elements and protrusions/recesses that allow vertical stacking and sliding, eliminating the need for screws and enabling easy assembly and disassembly, while providing structural stability against bending moments and allowing for reuse.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If screws are used for assembly and stability, then structural strength is improved, but device complexity and ease of operation deteriorate due to complicated construction and deconstruction

Engineering Contradiction:
Improvestructural strengthVSAvoidassembly complexity
Core Design Contradiction:
StrengthVSDevice complexity

Solution Approach 1:

The wall block is divided into multiple cross elements (first, second, and third cross elements) that extend between the front and back panels. Each cross element can be independently configured with protrusions or recesses, allowing the structure to achieve strength through distributed interlocking rather than relying on screw fasteners. This segmentation enables modular assembly where blocks connect through their respective cross elements without requiring additional fastening hardware.

Inventive Principle:
Principle #1Segmentation

2Stability of the object's composition

If a single protrusion extends laterally along the full width of the wall block, then structural stability is improved, but ease of operation deteriorates due to difficulty in assembling wall blocks

Engineering Contradiction:
Improvewall block stabilityVSAvoidassembly ease
Core Design Contradiction:
Stability of the object's compositionVSEase of operation

Solution Approach 1:

Instead of using a single long protrusion spanning the full width of the wall block, the invention divides the lateral connection into multiple separate protrusions associated with different cross elements. Each protrusion engages with a corresponding recess in a localized area, allowing the wall block to be assembled by sliding into position without requiring lateral movement across the entire width. This segmented approach maintains stability through distributed engagement while significantly improving assembly ease.

Inventive Principle:
Principle #1Segmentation

3Adaptability or versatility

If wall blocks are designed for easy disassembly and reuse, then adaptability and sustainability are improved, but structural strength and stability deteriorate

Engineering Contradiction:
ImprovereusabilityVSAvoidstructural strength
Core Design Contradiction:
Adaptability or versatilityVSStrength

Solution Approach 1:

The connection between wall blocks is designed to be dynamically adjustable rather than permanently fixed. The protrusions and recesses enable blocks to be easily inserted and removed, allowing the wall structure to be disassembled and reconfigured. Meanwhile, the multiple cross elements with interlocking features provide sufficient structural strength when assembled, creating a system that can transition between stable construction and easy disassembly as needed.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The wall block structure is segmented into multiple independent cross elements that can engage with corresponding elements in adjacent blocks. This segmentation allows the wall to be disassembled block by block or section by section without compromising the overall structural integrity when assembled. Each cross element with its protrusion-recess configuration provides localized strength while enabling modular reconfiguration for reuse in different wall configurations.

Inventive Principle:
Principle #1Segmentation
