Modular Wooden Wall System Using Hollow Elements to Reduce Weight
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing modular wooden wall systems are heavy due to the use of solid wood modules, limiting their variability and weight reduction potential.
Innovation Solution
A system comprising four distinct components: a base element, a hollow element, an insert skeleton, and a skeleton element, where the hollow element and insert skeleton are designed to reduce weight by using a cross-shaped structure, allowing for lightweight and versatile room element construction with connecting elements like screws, nails, adhesives, or Velcro, and enabling customizable designs with trays and sound-absorbing materials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If solid wood modules are used to construct wall systems, then structural integrity is maintained, but weight increases significantly
Solution Approach 1:
The solid wood module is segmented into three distinct components: a hollow element (outer frame), an insert skeleton (cross-shaped structure), and connecting elements. This segmentation allows the removal of excess material while maintaining the structural framework, thereby reducing weight while preserving structural integrity through the distributed skeleton system.
Solution Approach 2:
The solid wood module is replaced with a hollow element containing an insert skeleton, creating a porous or lattice-like structure. This approach removes unnecessary material from the solid block while maintaining structural strength through the strategically positioned skeleton framework, achieving significant weight reduction.
2Ease of manufacture
If standardized solid wood modules are used, then manufacturing is simplified, but design variability and aesthetic options are limited
Solution Approach 1:
By dividing the module into separable components (hollow element, insert skeleton, connecting elements), the system enables both standardized manufacturing of individual parts and flexible combination of these parts to create varied designs. The standardized接口 (connecting elements) simplifies manufacturing while the modular nature enables design variability.
Solution Approach 2:
The system transitions from a fixed, monolithic solid wood module to a dynamic, reconfigurable assembly of components. The connecting elements allow for different configurations and arrangements, enabling the same standardized components to create varied designs and layouts, thus increasing adaptability while maintaining manufacturing simplicity.
3Stability of the object's composition
If heavy solid wood modules are used, then structural stability is ensured, but handling and installation become more difficult
Solution Approach 1:
The heavy solid wood module is segmented into lighter individual components that can be handled and installed separately. The hollow element, insert skeleton, and connecting elements can be transported and positioned independently, then assembled on-site, significantly improving ease of operation while the interlocking design ensures structural stability is maintained.

AI summary
In a system for producing room elements, in particular walls, from individual construction elements, in particular made of wood, which are connected to one another to form the room element, at least four construction elements have different forms but are adapted to one another in terms of their dimensions. To this end, construction elements made of solid material are provided and construction elements consisting of hollow elements, into which an insertion frame is inserted. The construction elements are interconnected by means of pins, which are fastened in holes in the interior of the construction elements.
