Screen Frame Anchor Retention Assembly Corrosion Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Screened enclosure frame assemblies face rapid anchor corrosion and rust due to exposure to water and fluids, leading to structural integrity issues and frequent replacements.
Innovation Solution
A screen frame assembly with an anchor retention assembly that includes a support wall and cap to restrict fluid contact, preventing buckling and accumulation, and a screen retention assembly that allows maintenance without cap removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the anchor is driven through the frame element and into the base, then the frame element is securely anchored to the base, but the pressure causes the frame element to buckle or cave inward creating a concave configuration that accumulates water and causes rapid corrosion
Solution Approach 1:
A support wall is introduced as an intermediary component between the frame element and the base. This support wall prevents the frame element from buckling inward when the anchor is driven, eliminating the concave configuration that would otherwise accumulate water. The support wall mediates the mechanical stress while preventing the harmful geometric deformation.
Solution Approach 2:
The support wall is pre-installed in the frame element before the anchor is driven through. This preliminary action ensures that when the anchor is installed, the frame element already has structural reinforcement to prevent buckling, rather than allowing deformation to occur during the anchoring process itself.
2Strength
If water or fluid can seep under the outer edges of the frame element and into the interior portion where the anchor meets the base, then the anchor is securely installed, but the anchor experiences rapid deterioration, corrosion and rust
Solution Approach 1:
The support wall acts as a mediator that extends to the base, creating a barrier that prevents water and fluid from seeping under the outer edges of the frame element and reaching the anchor-base interface. This intermediary structure blocks the harmful fluid path while maintaining the secure mechanical connection.
Solution Approach 2:
The support wall functions as a protective barrier or shell that encloses the anchor region, preventing fluid infiltration. This thin film-like structure creates a protective environment around the anchor, isolating it from corrosive external elements while maintaining structural integrity.
3Ease of manufacture
If the frame element uses traditional anchoring without fluid restriction, then the installation is simple, but the anchor corrodes quickly requiring frequent replacement
Solution Approach 1:
The frame element is segmented into functional zones: an exterior region for aesthetic and structural purposes, and an interior anchor retention assembly region for secure anchoring. This segmentation allows the support wall to be integrated within the frame structure without complicating the overall installation process, while providing prolonged anchor protection.

AI summary
A screen enclosure frame element structured to resist fluid from contacting the anchor is presented. Particularly, the frame element comprises an anchor channel disposed within an interior portion of the frame element between a head surface and a support side; the anchor channel being dimensioned to receive an anchor there through and into an engaging relation with the base. Further, the frame element of at least one embodiment includes at least one anchor retention assembly which at least partially defines the anchor channel. The retention assembly comprises a support wall connected to or a part of an inner side of the head surface at one end, and disposable in a fluid restricting relation with the support base at the other end. Other embodiments include a cap with a curvilinear surface configuration and/or a plurality of support ledges with corrugates surfaces disposed in a fluid restricting relation with the base.
