Panel Edge Contour Inspection for Undercut Profile Accuracy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for inspecting decorative panels, such as those used in floating floor coverings, are prone to errors and depend heavily on human judgment, are destructive, and fail to ensure consistent quality due to variations in thickness and contour accuracy.
Innovation Solution
A method involving the use of sensors to record the contour of panel edges from multiple angles, forming a complete image of the profiled edge area, including undercut parts, using sensors like 2D triangulation position sensors, to ensure accurate inspection without destruction.

Engineering Contradiction Analysis
1Reliability
If traditional inspection methods (installation test, mould insertion, destructive testing) are used, then inspection can be performed, but the methods are error-prone, highly dependent on human judgment, and destructive
Solution Approach 1:
The patent replaces mechanical inspection methods (installation tests, mould insertion, physical sampling) with an optical measurement system using sensors that record contour data digitally. This substitution eliminates the destructive nature of traditional methods while improving reliability through objective, quantifiable measurements.
Solution Approach 2:
The invention creates a digital copy (contour recording) of the panel edge geometry instead of physically interacting with the actual panel. Multiple contour recordings from different angles are taken and compared against a reference, allowing inspection without physical contact or destruction of the inspected object.
2Device complexity
If single-angle contour recording is used, then inspection is simpler, but undercut profile parts cannot be fully captured
Solution Approach 1:
The patent adds an angular dimension to the inspection process by taking contour recordings from multiple different angles. This multi-angular approach ensures that undercut profile parts and locking features are captured from at least one angle where they are visible, completing the contour information without excessive complexity.
Solution Approach 2:
The system takes multiple contour recordings (more than the single recording that would be minimally required) from different angles. This excessive action ensures complete capture of all profile features including undercuts, with the understanding that not all recordings are equally necessary, but the redundancy guarantees information completeness.

AI summary
A process is for inspecting panels that have profiled edge areas with coupling parts. The process includes at least the step of recording at least the first and second parts of the contour of the cross-section of the first mentioned profiled edge areas. The first and second parts are recorded using one or more sensors. The recording of the first part is conducted from a first recording angle, while the recording of the second part is performed from a second recording angle that differs from the first recording angle. Each part is recorded from one or more transverse directions to the longitudinal direction of the corresponding edge. This method enables quality control on panels using such an inspection method and a device applied for this purpose.
