CLT Decorative Panel with Non-Newtonian Buffer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cross-laminated timber (CLT) panels face issues with poor decoration options and low impact resistance due to their log-based surface, which limits aesthetics and requires costly replacement upon damage, and existing connections between CLT panels and vertical structures are weak and difficult to reassemble.
Innovation Solution
A CLT decorative panel with a non-Newtonian fluid buffer layer and connecting device featuring a support body with connecting blocks, which enhances impact resistance and facilitates easier positioning and stronger connections by distributing impact forces and transferring structural stress.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If CLT panel is pressed from logs to maintain structural integrity, then manufacturing simplicity is improved, but surface decoration quality deteriorates
Solution Approach 1:
The CLT panel is divided into separate functional layers: a structural CLT layer for load-bearing and decorative layers for surface appearance. The decorative layers are attached to the CLT panel surface, allowing independent optimization of structure and aesthetics without compromising manufacturing simplicity.
2Shape
If CLT panel uses log-based surface to maintain natural appearance, then aesthetic simplicity is improved, but impact resistance deteriorates
Solution Approach 1:
The panel combines CLT structural layer with separate decorative layers and buffer layers containing non-Newtonian fluid. This composite structure provides both natural wood appearance and enhanced impact resistance, as the buffer layer absorbs impact energy while the CLT layer maintains structural integrity.
3Strength
If CLT panel uses integral structure to maintain structural strength, then connection strength is improved, but ease of repair deteriorates
Solution Approach 1:
The panel is designed with separable decorative layers that can be independently removed and replaced. The structural CLT layer remains intact while only the damaged decorative layer needs replacement, significantly improving repairability without compromising overall connection strength.
4Device complexity
If CLT panel uses simple bolt connection to maintain connection simplicity, then device complexity is reduced, but connection reliability deteriorates
Solution Approach 1:
Positioning protrusions and grooves are pre-formed on the CLT panel edges before assembly. These features guide the connection components into correct alignment during installation, ensuring accurate positioning and reliable connection while maintaining relatively simple connection structure.
