Cellulose Drywall Stud Profile for Low-CO2 Frame Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drywall partitions using metal or wooden frames face environmental issues (high CO2 emissions and recycling challenges for metal, and handling inefficiencies for wood), along with susceptibility to damage and handling problems.
Innovation Solution
A cellulose-based supporting structure, such as a stud profile with rounded edges and flanges, is used for drywall partitions, featuring a longitudinal beam made of recycled paper or cardboard, which can be partially or fully recyclable, and includes features like inclined flanges for easy assembly and through-holes for cables and pipes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If metal profiles are used for drywall partitions, then structural strength is achieved, but CO2 emissions increase and recycling becomes problematic
Solution Approach 1:
The patent changes the material parameter from metal to cellulose-based material, fundamentally altering the environmental characteristics while maintaining structural functionality through optimized geometry and layering of the profile walls
Solution Approach 2:
The patent uses composite material construction with multiple cellulose layers (7-10 layers of 0.5-0.9 mm each) bonded together, creating a composite structure that achieves metal-like strength while maintaining the environmental benefits of cellulose-based materials
2Quantity of substance
If thin metal material (0.6 mm) is used, then material efficiency is improved, but cuts occur during processing and frames are susceptible to damage
Solution Approach 1:
The patent constructs profiles from 7-10 layers of cellulose material, each 0.5-0.9 mm thick, bonded together to create a composite structure that is both material-efficient and damage-resistant, eliminating the brittleness of thin metal while maintaining thin-profile advantages
Solution Approach 2:
The patent rounds all edges and corners of the profile cross-section, eliminating sharp corners that are prone to damage and cuts during handling and installation, while the rounded geometry maintains structural integrity through distributed stress
3Object-generated harmful factors
If wooden beams are used for drywall partitions, then environmental issues are reduced, but weight and volume increase causing handling problems
Solution Approach 1:
The patent changes the material parameters by using compressed cellulose layers with optimized thickness (0.5-0.9 mm per layer) and high layer count (7-10 layers), creating a material density and strength profile that matches metal while maintaining environmental benefits and reducing weight compared to wood
Solution Approach 2:
The rounded edge design reduces material requirements at stress concentration points while improving handling characteristics, making the profiles easier to manipulate during installation compared to traditional wooden beams
