Wood Foldable Panel Hinge With Recessed Adhesive Layer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing foldable panels face issues with adhesive tapes being insufficiently connected to wood materials, leading to adhesion failure and visible adhesive when unfolded, and complex manufacturing processes.
Innovation Solution
A depression is formed in the panel parts on both sides of the joint to house the adhesive layer, ensuring a firm bond and a flat rear side, allowing for simple and cost-effective production with minimal visibility of the hinge when unfolded.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If adhesive tape with fabric is used to connect panel parts, then the panel parts can be pivotally connected, but the adhesive tape comes off after a while and the connection is insufficiently firm
Solution Approach 1:
The patent changes the adhesive application parameters by applying adhesive directly to the panel parts surfaces rather than using pre-formed adhesive tape. The adhesive is applied in a controlled manner to create optimal bonding conditions, improving both bond strength and durability compared to adhesive tape solutions.
Solution Approach 2:
The patent extracts the fabric carrier from the adhesive system, using only the adhesive material applied directly to the panel parts. This eliminates the weakness of adhesive tape where the fabric and adhesive can separate, creating a more reliable bond between panel parts.
2Ease of manufacture
If adhesive is placed in a gap at the side edges to connect panel parts, then the panel parts can be connected, but the adhesive is visible when the panel is unfolded and the manufacture is complex
Solution Approach 1:
The patent applies adhesive locally to specific areas of the panel parts - specifically to the side edges and rear surfaces where contact occurs during folding. This localized application ensures the adhesive is hidden in the folded position while maintaining connection functionality, and eliminates the need for complex groove structures.
Solution Approach 2:
Instead of placing adhesive in gaps or grooves as in conventional solutions, the patent applies adhesive to the surfaces that come into contact during folding. This inverted approach makes the adhesive hidden rather than visible, and simplifies the manufacturing process by eliminating groove formation.
3Ease of manufacture
If adhesive is applied to the back of panel parts without a depression, then the connection is simple, but the adhesive protrudes beyond the back and prevents flat stacking
Solution Approach 1:
The patent prepares the panel parts surfaces in advance by creating depressions or recesses where the adhesive will be applied. This preliminary action ensures that when adhesive is applied, it remains contained within the depression and does not protrude beyond the panel back surface, enabling flat stacking while maintaining simple adhesive application.

AI summary
Folding plate has two plate parts separated from each other, which have a front side (4a,4b) and a back side (6a,6b). A hinge element (8) consisting of adhesive, whereby the hinge element connects the both plate parts (2a,2b) with each other in a tilted manner. Folding plate is made of a timber product or of wood. The hinge element is provided as an adhesive layer (10) on the back side of the plate parts.
