Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing OSB boards used in wall construction require complex logistics and heavy machinery for transport and assembly, making them unsuitable for simpler wall systems like garages or garden houses, which are often constructed by smaller builders or individuals without heavy equipment.
Innovation Solution
A portable building element made of wood-based panels, featuring a tongue and groove design with an offset inner panel, allowing manual assembly and interlocking for stable wall construction without heavy machinery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If complete walls with solid wooden frames and OSB boards are used for wall construction, then structural strength and stability are improved, but weight and device complexity increase, requiring heavy-duty transport vehicles and construction cranes
Solution Approach 1:
The wall system is divided into modular building elements that can be assembled in sections. Each element contains a structural frame with OSB boards attached, but the modules are sized to be manageable and transportable without heavy machinery. The tongue and groove connections between modules provide structural continuity while maintaining individual module portability.
Solution Approach 2:
The OSB boards are attached to the wooden frame in a nested configuration where the boards are positioned within the frame structure. The frame provides the primary structural support while the OSB boards are nested within and attached to the frame members, creating a compact integrated unit that maximizes strength while minimizing overall dimensions for transport.
2Strength
If complete walls with solid wooden frames and OSB boards are used for wall construction, then structural strength and stability are improved, but device complexity increases, requiring heavy-duty transport vehicles and construction cranes
Solution Approach 1:
The wall system is divided into modular building elements that can be assembled in sections. Each element contains a structural frame with OSB boards attached, but the modules are sized to be manageable and transportable without heavy machinery. The tongue and groove connections between modules provide structural continuity while maintaining individual module portability.
Solution Approach 2:
The building elements are designed to be self-assembling through the tongue and groove connection system. The modules connect to each other without requiring external equipment or complex fastening procedures, allowing manual assembly by small construction teams or even individual builders, thereby eliminating the need for complex logistics and heavy machinery.
3Stability of the object's composition
If complete walls with solid wooden frames and OSB boards are used for wall construction, then structural stability is improved, but ease of operation deteriorates, making manual assembly difficult without heavy equipment
Solution Approach 1:
The wall system is divided into modular building elements that can be assembled in sections. Each element contains a structural frame with OSB boards attached, but the modules are sized to be manageable and transportable without heavy machinery. The tongue and groove connections between modules provide structural continuity while maintaining individual module portability.
Solution Approach 2:
The building elements use uniform materials (wooden frames with OSB boards) and consistent connection methods (tongue and groove joints with adhesive). This homogeneity in material selection and assembly procedure simplifies the construction process, allowing workers to become proficient quickly and assemble walls efficiently without requiring different techniques or equipment for different wall sections.
4Manufacturing precision
If tongue and groove connections with adhesive are used to join OSB boards, then manufacturing precision is improved, but ease of manufacture deteriorates, requiring specialized assembly procedures
Solution Approach 1:
The building elements use uniform materials (wooden frames with OSB boards) and consistent connection methods (tongue and groove joints with adhesive). This homogeneity in material selection and assembly procedure simplifies the construction process, allowing workers to become proficient quickly and assemble walls efficiently without requiring different techniques or equipment for different wall sections.

AI summary
The present invention relates to a portable building element (10) made of a wood material for a modular wall system, comprising at least three rectangular, planarly interconnected (glued) wood material panels, wherein at least one inner wood material panel (12) is arranged between two outer wood material panels (11a, 11b) forming the outer sides of the building element, wherein the at least one inner wood material panel (12) is displaced in the xy direction with respect to the two outer wood material panels (11a, 11b) by a predetermined x value and a predetermined y value such that the inner wood material panel protrudes at two adjacent side edges by the predetermined x value and predetermined y value between the two outer wood material panels, forming a projection/spring projection,and is inserted at the two side edges opposite the protruding side edges by the predetermined x-value and predetermined y-value relative to the two outer wood-based panels, forming a groove. The present invention also relates to a modular wall system producible from these portable building elements.
