Shaped Countertop Edge Lamination for Custom Corners and Cut-Outs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing countertops, especially custom-manufactured ones, face challenges in creating aesthetically pleasing corners, bump-outs, and cut-outs, and often have a thicker finished edge due to the downwardly-extending lip, which is not in line with the substrate thickness.
Innovation Solution
A method involving heating a sheet laminate, bending it to a formed shape, applying adhesive to the laminate or substrate, and using a clamping press assembly to secure the laminate to the substrate, allowing for angle-cutting to match the countertop's contours and maintaining the same thickness as the substrate.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a downwardly-extending lip is added to the countertop edge, then the countertop can be securely mounted to the base, but the finished edge becomes thicker and bulbous in appearance
Solution Approach 1:
The patent moves the mounting function from the vertical dimension (downward lip) to the horizontal dimension (side-mounted adhesive strip). The adhesive strip is applied to the side surface of the countertop substrate, allowing secure mounting without adding vertical thickness to the edge profile.
Solution Approach 2:
The mounting function is extracted from the edge structure itself and separated into a distinct adhesive component. The adhesive strip is applied to the side surface, removing the need for the edge to extend downward for mounting purposes.
2Ease of manufacture
If mass-produced countertops use a standardized edge profile, then manufacturing is simplified, but custom corners, bump-outs, and cut-outs cannot be easily accommodated
Solution Approach 1:
The countertop system is segmented into two independent components: the substrate (which maintains standardized production) and the edge band (which provides custom shaping). The edge band is applied separately to the substrate, allowing the substrate to be manufactured efficiently while the edge band is customized to match specific design requirements.
Solution Approach 2:
The edge band provides localized customization only where needed at the edges and corners of the countertop, while the main substrate body retains its standardized construction. This allows custom corners, bump-outs, and cut-outs to be achieved through the edge band's adaptability without complicating the overall manufacturing process.
3Reliability
If the finished countertop edge is made thicker with a lip, then mounting stability is improved, but the aesthetic appearance and professionalism are reduced
Solution Approach 1:
An adhesive strip serves as an intermediary component between the countertop substrate and the base. This adhesive mediator provides the necessary mounting stability and bonding strength without requiring the substrate or edge to extend downward, thereby maintaining a clean, professional aesthetic appearance.

Function Achieved in This Case
This approach enables the production of custom countertop edges that are aesthetically pleasing, easily angle-cut to accommodate corners and cut-outs, and match the substrate thickness, improving the appearance and professionalism of finished countertops.
Implementation Method 1
heating a sheet laminate to an elevated temperature
Implementation Method 2
applying adhesive to at least one of the formed laminate or a substrate

AI summary
A method of manufacturing a shaped counter top edge includes heating a sheet laminate to an elevated temperature, bending the sheet laminate to a formed laminate, and applying adhesive to at least one of the formed laminate or a substrate comprising a substrate upper face, a substrate lower face, and a substrate shaped edge positioned between the substrate upper face and the substrate lower face. The method also includes positioning the formed laminate proximate to the substrate upper face, the substrate lower face, and the substrate shaped edge, and clamping the formed laminate to the substrate upper face, the substrate lower face, and the substrate shaped edge of the substrate with a clamping press assembly until the adhesive cures to form a substrate/laminate assembly from the formed laminate and the substrate. The method further includes cutting a portion of the substrate/laminate assembly to form the shaped counter top edge.
