Segmented Wood Panels for Construction Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wood-based panels for construction systems face inefficiencies in wood usage, cost, and insulation space, particularly in high-rise buildings, where excessive wood is required to ensure load-bearing capacity and thermal resistance.
Innovation Solution
A method for manufacturing wood-based load-bearing panels that adapts the number and distribution of wood-based strips within each panel based on the specific load-bearing requirements of its position in the construction system, using a panel template that can be varied to optimize wood usage and incorporate more insulation material.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If CLT panels use contiguous strips bonded together to form solid layers, then strong mechanical resistance is achieved, but significant volume of wood is required which is inefficient in terms of wood usage, glue, and costs
Solution Approach 1:
The panel is segmented into discrete wooden strips spaced apart rather than contiguous, with each strip acting as an independent structural element. This segmentation reduces wood consumption while maintaining load-bearing capacity through optimized strip placement and spacing.
Solution Approach 2:
Wooden strips are strategically positioned at locations requiring structural support, with varying spacing distances between strips. This local quality approach concentrates wood material where structurally necessary while reducing it in areas where insulation or other functions are prioritized.
2Strength
If contiguous strips are used in CLT panels, then structural strength is improved, but there is no room between the strips for inserting insulating elements
Solution Approach 1:
By segmenting the panel into spaced wooden strips rather than using contiguous strips, the invention creates clearances between strips that can accommodate insulating elements, bracing panels, and other functional components while preserving structural integrity.
Solution Approach 2:
The spacing between wooden strips is optimized locally to accommodate specific functional requirements such as insulation thickness, allowing the panel to meet both structural and thermal performance criteria simultaneously.
3Stability of the object's composition
If strips are bonded together on their side to form solid layers of the size of the pre-manufactured panel, then panel integrity is achieved, but openings must be cut which increases production time and generates useless wood pieces
Solution Approach 1:
The panel design uses individually positioned wooden strips that can be installed in their final locations without requiring post-manufacturing cutting operations. This segmentation approach eliminates the need to cut openings after panel assembly, reducing production time and wood waste.
Solution Approach 2:
The positions of wooden strips are predetermined and pre-planned in the panel design, allowing all structural and functional elements to be integrated during the initial manufacturing process without requiring subsequent cutting or modification operations.
4Reliability
If the same panel structure is used for all walls to ensure load-bearing capacity, then structural safety is maintained, but panels are oversized in terms of wood quantity leading to inefficiency
Solution Approach 1:
The panel structure is customized for each wall based on its specific load-bearing requirements, with wooden strip spacing and dimensions optimized locally. This allows panels to use only the necessary amount of wood for their particular structural demands rather than being uniformly oversized.
Solution Approach 2:
The panel design is made adaptive and dynamic, allowing the wooden strip configuration to be modified based on the specific structural, thermal, and functional requirements of each wall location, rather than using a static uniform design for all panels.
