Cover Plates with Segmented Edges for Rainproof Overlap
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cover devices with overlapping edges struggle to maintain rainproof integrity, especially when subjected to deformation or loading inaccuracies, leading to potential water infiltration.
Innovation Solution
The design features edges with differentiated overlapping mechanisms, including a rain gutter under one edge and a free edge on the other, which collect and divert rainwater, combined with clamping webs for secure alignment and assembly, allowing for self-supporting and rainproof configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If edges of cover plates are designed to overlap for rainproof connection, then structural simplicity is improved, but rainproof reliability deteriorates when deformation or loading occurs
Solution Approach 1:
The edge of the cover plate is segmented into multiple functional components: an upper web that continues the top side, a rain gutter positioned below the web, and a clamping web. This segmentation allows each component to perform its specific function - the web provides structural continuity, the gutter collects and channels rainwater, and the clamping web ensures secure connection - thereby maintaining rainproof reliability without excessive overall complexity.
Solution Approach 2:
The rain gutter acts as an intermediary element between the overlapping edges of adjacent cover plates. It provides a dedicated pathway for rainwater that may penetrate through the web overlap, collecting and diverting it away from the underlying structure. This intermediary component ensures rainproof reliability even when the primary web-to-web connection is compromised by deformation or assembly inaccuracies.
2Strength
If cover plates are made rigid for structural stability, then strength is improved, but adaptability to deformation and thermal expansion deteriorates
Solution Approach 1:
The clamping connection between adjacent cover plates is designed with localized flexibility. While the cover plates themselves maintain overall rigidity for structural strength, the clamping webs allow for local adjustment and movement. This local quality enables the rigid plates to accommodate thermal expansion and contraction as well as minor deformations without compromising the overall structural integrity or rainproof connection.
3Reliability
If precise manufacturing and assembly are required for rainproof overlap, then rainproof reliability is improved, but ease of manufacture deteriorates
Solution Approach 1:
The edge design features asymmetric positioning of components relative to the cover plate thickness. The upper web continues the top side and is positioned at a specific height, while the rain gutter is located below it at a different level, and the clamping web is positioned to engage with the adjacent plate. This asymmetric arrangement creates a self-aligning mechanism that guides assembly and compensates for manufacturing tolerances, maintaining rainproof reliability without requiring extremely precise manufacturing and assembly.

AI summary
A cover apparatus (1), comprising cover plates (2) continuing in a position of use in a common plane and in at least one row, is formed in a mutual edge-side contact region (3) through overlapping and in a rainproof manner, such that edges (5) running parallel to each other and spaced apart on each cover plate (2) are designed differently (6), and the top side (7) of the cover plate (2), a continuing web (8) and a rain gutter (9) under said web (8) are arranged on a first edge (5), wherein said rain gutter belongs to the same first edge (5). If necessary, penetrating rain water (12) can be caught in the rain gutter (9) by overlapping edge-side webs (8) in the position of use.
