Solution Overview

Problem

Existing methods for constructing walls in wood frame buildings are complex, costly, and prone to manufacturing uncertainties due to the dissociation of insulation and carrier systems, leading to logistical challenges and variable quality.

Innovation Solution

The use of simple, inexpensive elementary modules comprising a rectangular structural frame and filler panels made of agglomerated particles, pre-insulated with thermally and acoustically insulating material, which are easily assembled and do not require solid wood, reducing the need for vapor barriers and allowing for easy handling and recycling of materials.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If prefabricated large panels are used, then manufacturing quality is guaranteed, but logistics and transport costs increase significantly

Engineering Contradiction:
Improvemanufacturing qualityVSAvoidlogistics cost
Core Design Contradiction:
Manufacturing precisionVSWeight of moving object

Solution Approach 1:

The wall system is divided into modular panels of manageable dimensions that can be easily transported and assembled on-site. Each panel is a self-contained unit with integrated insulation and structural frame, allowing segmentation of the overall wall construction into transportable components without compromising manufacturing quality.

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If insulation and carrier systems are dissociated, then flexibility in construction is improved, but manufacturing precision deteriorates due to variable assembly conditions

Engineering Contradiction:
Improveconstruction flexibilityVSAvoidassembly precision
Core Design Contradiction:
Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The insulation system and carrier system are merged into a single integrated panel structure. The insulation material is permanently fixed within the panel framework during factory manufacturing, ensuring precise positioning and eliminating variability introduced by on-site assembly. This integration maintains construction flexibility while guaranteeing manufacturing precision.

Inventive Principle:
Principle #5Merging (Combining)

3Strength

If solid wood is used, then structural strength is improved, but cost and environmental impact worsen

Engineering Contradiction:
Improvestructural strengthVSAvoidmanufacturing cost
Core Design Contradiction:
StrengthVSEase of manufacture

Solution Approach 1:

The panel structure uses composite materials combining wood-based agglomerated particles for the frame with rigid insulation material. This composite construction achieves required structural strength while using recycled wood materials, reducing both cost and environmental impact compared to traditional solid wood construction.

Inventive Principle:
Principle #40Composite materials

4Ease of operation

If modules are made portable with small dimensions, then ease of handling is improved, but the complexity of assembling multiple modules increases

Engineering Contradiction:
Improvehandling easeVSAvoidassembly complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

All panels are designed with standardized dimensions, connection points, and fixing fin configurations that provide universal compatibility. This standardization allows simple, repeatable assembly procedures despite the modular nature of the system, reducing assembly complexity while maintaining portability and ease of handling.

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

AI summary

The wall (17) has elementary modules (10) e.g. lintels, with a rectangular structure frame constituted of vertical panels (11), horizontal panels made of oriented strand board (OSB) type agglomerate particles, and filling panels (13) made of agglomerate particles closing the frame. Each module is in a form of a parallelepiped block. The vertical and horizontal panels are extended along direction of exterior of the block with respect to one of the filling panels to form fixation blades (14). The modules are fixed in an adjacent manner to the blades maintained in contact by fixation units. The block is made of phonic and thermal insulating material such as cellulose wadding material.
