L-Shaped Lintel Cover with Lip for Corrosion Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lintel covers are difficult to install, prone to sliding, and require additional fastening means, often leaving gaps that allow water and debris to enter, compromising their effectiveness in protecting metal lintels from corrosion and deterioration.
Innovation Solution
A flexible, L-shaped cover with a continuous wall configuration, featuring an upper wall taller than the lintel's rise, a U-shaped opening, and a back wall forming a lip, which provides a secure fit without adhesives or fasteners, ensuring complete coverage and protection of the lintel's exterior surface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a lintel cover with a lip shorter than the lintel height is used, then the ease of installation is improved, but the protection effectiveness deteriorates as the top of the lintel remains exposed to water and debris
Solution Approach 1:
The patent transitions from a conventional lip-based retention system to a dimensional envelope approach where the cover extends beyond the lintel in multiple directions (sides and top) to create a complete protective envelope. This dimensional expansion ensures full coverage while maintaining installation ease through the continuous wall design that wraps around the lintel.
Solution Approach 2:
The cover is constructed as a flexible, continuous wall structure that can conform to the lintel dimensions and wrap around it completely. This flexible shell design allows the cover to envelop the entire lintel surface including the top edge, providing comprehensive protection without requiring rigid fastening systems.
2Stability of the object's composition
If additional clips and fastening means are used to secure the lintel cover, then the stability of the cover is improved, but the device complexity and ease of installation deteriorate
Solution Approach 1:
The cover design employs self-retention mechanisms where the continuous wall structure itself provides the securing function through friction and geometric interlocking with the lintel. The cover's own structural features (continuous walls, appropriate dimensions) create the retention force, eliminating the need for separate fastening components and making the system self-sufficient.
Solution Approach 2:
The patent merges the protective function and the securing function into a single integrated structure. The continuous wall cover simultaneously provides protection and stability through its geometric relationship with the lintel, combining what were previously separate functions (coverage and fastening) into one unified component system.
3Reliability
If the lintel cover uses a continuous wall design with complete coverage, then the protection effectiveness is improved, but the amount of material and manufacturing complexity increases
Solution Approach 1:
The continuous wall cover is manufactured as a flexible, thin-walled structure that can be formed into the required envelope shape. This flexible shell construction allows for complete coverage while maintaining manufacturing simplicity through extrusion or forming processes that create the continuous wall profile in a single operation.
Solution Approach 2:
The continuous wall design serves multiple functions simultaneously: it provides the primary protective barrier, creates the structural envelope, and generates the retention force through its geometric configuration. This multi-functionality reduces the need for additional components and simplifies the overall manufacturing process by consolidating functions into a single structural element.

AI summary
The present invention relates to a lintel or angle iron cover, and specifically a cover for an L-shaped lintel having a rise portion and a run portion. The cover is also L-shaped and is a continuous wall made up of an upper wall joined to a top wall which is joined to a side wall. The side wall is also joined to a bottom wall which is joined to a back wall. Further, the upper wall is at least as high as the rise portion of the lintel. The top wall and bottom wall form a U-shaped opening closed by the side wall, and the U-shaped opening is the size of the run portion. Whereas the back wall forms a lip at the end of the bottom wall.
