Find Innovative SolutionsGenerate Solutions
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
Engineering Contradiction Analysis
1Manufacturing precision
If prefabricated large panels are used, then manufacturing quality is guaranteed, but logistics and transport costs increase significantly
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.
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
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.
3Strength
If solid wood is used, then structural strength is improved, but cost and environmental impact worsen
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.
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
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.

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.
