Solution Overview

Problem

Existing modular building systems, such as those described in WO 2005/124049, face challenges in assembly complexity, transport efficiency, and structural stability, particularly due to the need for precise installation of bracing members and cumbersome stacking of L-shaped corrugated sheets.

Innovation Solution

A modular building panel design featuring a first and second side wall angled relative to each other, allowing for easy stacking and assembly into a wall configuration, utilizing corrugated material with bends for flexibility and connectivity through connecting members and fasteners.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If L-shaped corrugated sheets are used to form U-shaped panels, then structural strength and stability are improved, but transport efficiency deteriorates due to cumbersome stacking

Engineering Contradiction:
Improvestructural strengthVSAvoidtransport efficiency
Core Design Contradiction:
StrengthVSProductivity

Solution Approach 1:

The panel is designed to be dynamically transformable between two configurations: a compact first position for transport with side walls angled at less than 180 degrees, and an assembled second position with side walls parallel to each other forming the U-shape. This dynamic adaptability allows the same structure to optimize for both strength during assembly and efficiency during transport.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The panel incorporates movable joints that divide the rigid U-shaped structure into separatable segments, allowing the side walls to be independently positioned. This segmentation enables the panel to be disassembled into a flatter configuration for transport while maintaining the complete U-shape for structural applications.

Inventive Principle:
Principle #1Segmentation

2Stability of the object's composition

If bracing members are installed within panels, then structural stability is improved, but assembly complexity increases due to requirement for expertise

Engineering Contradiction:
Improvestructural stabilityVSAvoidassembly complexity
Core Design Contradiction:
Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The bracing members are pre-installed within the panels during manufacturing, so that when panels are stacked or assembled, the bracing is already in place. This preliminary action eliminates the need for on-site installation of bracing members, reducing assembly complexity while maintaining structural stability.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The bracing members are integrated into the panel structure itself rather than being separate components. This merging of functions combines the panel body and bracing into a single assembled unit, simplifying the overall assembly process while ensuring structural integrity.

Inventive Principle:
Principle #5Merging (Combining)

3Stability of the object's composition

If side walls are parallel and opposed in assembled position, then structural stability is improved, but transport efficiency deteriorates

Engineering Contradiction:
Improvestructural stabilityVSAvoidtransport volume
Core Design Contradiction:
Stability of the object's compositionVSVolume of moving object

Solution Approach 1:

The panel is designed to be dynamically transformable between two configurations: a compact first position for transport with side walls angled at less than 180 degrees, and an assembled second position with side walls parallel to each other forming the U-shape. This dynamic adaptability allows the same structure to optimize for both strength during assembly and efficiency during transport.

Inventive Principle:
Principle #15Dynamics

AI summary

A building panel is constructed of a corrugated material. The panel can be folded into a U-shaped configuration. Successive folded panels can be coupled together using complementary shaped corrugations to fix panels in position relative to each other. Shaped connectors can be used to connect building panels in one plane to building panels in another plane.
