Lintel Cover Lip Design for Moisture Diversion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lintel coverings are either cumbersome to install, require regular maintenance, or cause water pooling issues, leading to oxidation and damage of steel lintels.
Innovation Solution
A lintel cover with a lip extending partially up the upper portion, allowing for easy installation and complete coverage, combined with a flexible covering like polyethylene flashing and tar paper to divert moisture away from the structure, preventing oxidation and damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If an angle iron cover is used to protect the lintel, then aesthetic appearance is improved, but water pooling occurs leading to oxidation and damage
Solution Approach 1:
The patent introduces a third dimensional element by adding a lip that extends upward from the cover surface. This lip creates a barrier that changes the water flow path, directing it away from the lintel interface and preventing pooling in the problematic area where the cover meets the structure.
Solution Approach 2:
The lip acts as an intermediary element between the cover and the structure. It intercepts water before it can reach the vulnerable interface between the lintel and structure, effectively mediating the water flow and protecting the joint from oxidation and damage.
2Reliability
If a lintel cover with flap and hinge bend is used to create sealed air space, then protection from weathering is improved, but installation becomes cumbersome
Solution Approach 1:
The patent divides the cover into distinct functional segments: a main cover body for protection and a separate lip extension for water management. This segmentation allows each component to be optimized independently - the cover body provides weathering protection while the lip handles water diversion, and the simplified geometry makes installation easier.
Solution Approach 2:
The patent extracts the water management function from the complex flap and hinge bend mechanism and implements it through a simple lip extension. This takes out the unnecessary complexity of folds and hinges while retaining the essential function of weather protection and water diversion.
3Reliability
If existing coverings are used to protect the lintel, then oxidation protection is improved, but regular maintenance is required
Solution Approach 1:
The lip design creates a self-draining system that passively diverts water away from the lintel interface without requiring active maintenance. The geometric configuration automatically channels water flow, eliminating the need for regular cleaning or intervention that would be required by more complex sealed systems.

AI summary
A lintel cover is installable on a lintel to protect the lintel from exposure to the elements and moisture. The lintel cover has an upper surface, side surface, lower surface and lip. The lip is preferably shorter than the height of an upper portion of the lintel to increase the ease of installation.
