Alternating Material Block Floor Panel Core
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing parquet floor panels have limited cost reduction potential despite advancements in surface treatment and glue technology, with a need for improved control over core properties such as strength and weight.
Innovation Solution
A floor panel design featuring a core composed of alternating first and second material blocks, where the first blocks are oriented perpendicular to the core's principal direction and the second blocks are parallel, differing in material properties like density and tensile strength, allowing for improved control over core properties and cost reduction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional low-grade wood blocks are used for the core, then cost is reduced, but control over core properties such as strength and weight is limited
Solution Approach 1:
The core is divided into alternating first material blocks and second material blocks that differ substantially in material properties. This local differentiation allows specific regions to provide different functions - some blocks contribute to strength while others contribute to weight reduction or cost reduction, enabling precise control over overall core properties
Solution Approach 2:
The core uses a composite structure combining different material blocks (first material blocks and second material blocks) with substantially different material properties. This composite approach allows the core to achieve a balance between strength, weight, and cost that cannot be obtained with a single uniform material
2Strength
If higher strength materials are used for the core, then structural integrity is improved, but cost increases
Solution Approach 1:
First material blocks and second material blocks are arranged alternately, with at least one block type providing superior strength properties. This localized strength distribution ensures structural integrity where needed while using less expensive materials in other regions, reducing overall cost
Solution Approach 2:
The core is segmented into multiple discrete material blocks rather than using a single continuous material. This segmentation allows strategic placement of high-strength blocks at critical locations while using lower-cost materials in non-critical areas

AI summary
The present document discloses a core for inclusion in a building panel 1". The core presents a pair of substantially parallel major surfaces, and comprises a plurality of first material blocks 10', extending between said major surfaces and arranged with their respective principal directions substantially parallel with said major surfaces and extend 90° ± 45° to a principal direction of the core; and a plurality of second material blocks 11', extending between said major surfaces and being arranged alternatingly with said first material blocks along the principal direction of the core. The first material blocks and said second material blocks differ substantially with respect to at least one material property.
