Wood Panel With Staggered Interleaved Slats For Insulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wood panels for building construction require large amounts of material, leading to high costs and significant material losses due to insufficient mechanical strength, sound insulation, and thermal insulation properties, with existing solutions not effectively addressing these issues.
Innovation Solution
A wood panel design featuring several superposed layers of non-adjoining wooden slats with identical cross-sections, positioned parallel and perpendicular to each other with specific spacing and offset, creating three-dimensional baffles that enhance mechanical strength, reduce material usage, and improve sound and thermal insulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If panels are made of wooden slats assembled in several layers of contiguous and intersecting wooden slats to reduce production costs and avoid large-section pieces, then mechanical strength is improved, but material quantity remains significant and thermal and sound insulation properties are not significantly improved
Solution Approach 1:
The panel is segmented into multiple layers of non-contiguous wooden slats with intervals between them, rather than using solid contiguous wood. This segmentation reduces material quantity while maintaining structural integrity through the layered configuration
Solution Approach 2:
The invention transitions from two-dimensional contiguous slat arrangements to three-dimensional alternating layer configurations with intervals. The alternating layers create a spatial structure that improves insulation properties while reducing material usage
2Quantity of substance
If panels are made of wooden slats assembled in several layers of non-adjoining wooden slats to reduce material quantity and weight, then material consumption is reduced, but sound and thermal insulation properties remain mediocre
Solution Approach 1:
By arranging slats in alternating layers with intervals and offsets, the invention creates three-dimensional baffles that extend insulation paths in multiple spatial dimensions, significantly improving sound and thermal insulation without adding material
Solution Approach 2:
The intervals between non-adjoining slats act as intermediary insulating spaces, creating thermal and acoustic barriers that enhance insulation properties without requiring additional insulating materials
3Strength
If panels are made with contiguous pieces of wood in a single layer to ensure sufficient mechanical strength, then structural strength is achieved, but material quantity and production cost increase significantly
Solution Approach 1:
Instead of using a single layer of large-section contiguous wood, the invention segments the structure into multiple layers of smaller non-contiguous slats, distributing the structural load while reducing total material consumption
Solution Approach 2:
The invention adds a vertical layering dimension to the structure, creating alternating layers that provide mechanical strength through distributed support rather than relying on thick single-layer sections

AI summary
Panel (1) of wooden battens comprising layers of wood battens in alternating orientations (X, Y). The wood battens of each layer are separated by a centre-to-centre distance (E). Layers of wood battens (C1, C3, C5) are oriented in a first orientation (X). Layers of wood battens (C2, C4, C6) are oriented in a second orientation (Y) perpendicular to the first orientation (X). The layers of wood battens (C2, C4, C6) are interleaved between the layers of wood battens (C1, C3, C5). In two consecutive layers having the same orientation, the battens are staggered by a distance (D).
