Composite Panel Mounting via Groove Undercuts for Rigidity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing panel construction systems lack sufficient flexural strength and rigidity, and expose mounting metal fittings, resulting in an unattractive appearance when mounted on ceilings or walls.
Innovation Solution
A layered composite panel construction system with a groove on its back surface and an undercut portion, combined with rail members that are mounted using claw portions, providing improved flexural strength and rigidity while keeping the mounting structure hidden from view.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If mounting metal fittings are disposed on the four corners of the panel, then the panel can be mounted to the ceiling or wall, but the flexural strength and flexural rigidity of the panel remain relatively low
Solution Approach 1:
The panel back surface is segmented into multiple regions with grooves and undercut portions positioned at specific locations rather than corner-only mounting. This segmentation allows for distributed stress coverage and improved flexural strength while maintaining a relatively simple mounting structure.
Solution Approach 2:
The invention transitions from two-dimensional corner mounting to a three-dimensional mounting system that incorporates grooves and undercut portions extending into the panel thickness. This dimensional change enables the mounting fittings to engage with the panel at multiple depth levels, significantly improving flexural strength and rigidity.

3Ease of manufacture
If mounting metal fittings are exposed on the end faces of the exterior panel, then the panel can be mounted to the frame, but the appearance of the exterior panel becomes unattractive
Solution Approach 1:
The mounting function is extracted from the visible front surface of the panel and relocated to the back surface through grooves and undercut portions. This extraction allows the mounting fittings to be positioned on the reverse side, eliminating their visual impact on the panel's appearance while preserving full mounting capability.
Solution Approach 2:
The invention inverts the conventional mounting approach by placing mounting features on the back surface rather than the front surface. This inversion enables the panel to maintain an clean, attractive appearance from the viewing side while still providing effective mounting points on the opposite side.

AI summary
Provided are a panel construction member and a mounting structure for the same that can be rigidly mounted to a building and for which the panel, after being mounted, has excellent flexural strength and flexural rigidity. A panel construction member 1 has a layered structure in which a core plate 4 is disposed between a pair of metal plates 2, 3, wherein the panel construction member 1 is provided with a groove 5 that extends along at least one pair of edges of the panel construction member 1, and an undercut portion 5a that penetrates between the metal plates 2, 3 from the groove 5. A rail member 6 is mounted in the groove 5 of the panel construction member 1, and the panel construction member 1 is mounted to a ceiling or a wall by means of the rail member 6.
