Composite Structural Element with Veneer-Covered Joints for Furniture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing structural elements for furnishing, such as furniture, face challenges in achieving a reasonable cost while maintaining desired strength and quality, particularly with solid wood, which is often expensive and difficult to process.
Innovation Solution
A composite structural element is created by joining a core element made of a first material, typically cheaper wood, with end elements made of a second, more expensive wood, and covering the joint with a veneer layer to create a uniform outer surface, optimizing the core for one property and the outer surface for another.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If solid wood of expensive species is used for the entire structural element, then aesthetic appearance and strength are improved, but manufacturing cost increases and processability deteriorates
Solution Approach 1:
The structural element is divided into a core element and end elements made of different materials. The core element uses cheaper, easier-to-process wood while end elements provide aesthetic appearance and strength where needed, resolving the contradiction between overall strength and ease of manufacture.
Solution Approach 2:
Different parts of the structural element use different materials optimized for their specific functions: cheaper wood for the core where strength is less critical, and expensive hardwood for end elements where aesthetic appearance and strength are most important, thus improving both strength and ease of manufacture locally.
2Shape
If solid wood of expensive species is used for the entire structural element, then aesthetic appearance is improved, but manufacturing cost increases
Solution Approach 1:
The structural element is segmented into core and end elements with different materials. Only the visible end elements use expensive hardwood for aesthetic appearance, while the bulk core uses cheaper wood, reducing manufacturing cost while maintaining aesthetic appearance where visible.
Solution Approach 2:
Expensive hardwood is applied locally only to end elements where aesthetic appearance matters, rather than throughout the entire structural element. This local application maintains aesthetic appearance while significantly reducing overall manufacturing cost.
3Shape
If a veneer layer is applied to cover joints, then aesthetic appearance is improved, but manufacturing complexity increases
Solution Approach 1:
The core element and end elements are precisely shaped and prepared in advance with appropriate joining surfaces before assembly. This preliminary preparation enables simple joining operations and facilitates subsequent veneer application, improving aesthetic appearance while controlling manufacturing complexity through advance planning.
Solution Approach 2:
The veneer layer is applied locally to cover joints and transition zones rather than the entire surface. This selective application improves aesthetic appearance by hiding joints while minimizing the complexity of the veneering process itself.

AI summary
The present disclosure relates to a structural element and a method for producing a structural element for furnishing, e.g. for furniture. There is provided a core element 1 in a first material and at least one end element 3 in a second material, which are joined to form a composite element 11 with at least one joint 9. A veneer layer 13 in a veneer material is provided on the composite element 11, such that it at least partially covers said at least one joint 9. This allows a structural element to be provided which has a full outer surface in the second material to provide a second material finish, although the core is provided in another material which may have other preferred properties.
