Storm Trim Stacked Screw Boss Prevents Frame Penetration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing window protection methods during strong winds, such as hurricanes, often require penetrating screws into the building frame, leading to potential water damage and increased internal pressures, and may not provide sufficient holding power against high winds.
Innovation Solution
A lineal storm trim made of extruded vinyl with a stacked screw boss that can receive anchoring screws along its length, preventing screw penetration into the building frame and providing enhanced holding power, while also being aesthetically compatible with the window frame and capable of integrating with various window structures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If anchoring screws are driven into the building frame to secure panels, then holding power against strong winds is improved, but water damage and wood rot from screw holes occur
Solution Approach 1:
The lineal base acts as an intermediary component between the panel and the building frame. It provides a dedicated receptacle (screw boss) that captures and contains the anchoring screws, allowing them to secure the panel without penetrating into the building frame structure, thereby preventing water damage while maintaining holding power.
Solution Approach 2:
The fastening system is segmented into distinct functional components: the lineal base with its integrated screw boss separates the anchoring function from the structural frame. This segmentation allows screws to be contained within the lineal base rather than penetrating the building frame, resolving the contradiction between securing strength and water protection.
2Object-affected harmful factors
If a lineal base with screw boss is added to the window frame, then water damage is prevented, but device complexity increases
Solution Approach 1:
The lineal base merges multiple functions into a single component: it serves as both the mounting structure for the panel and the water management system through its integrated screw boss design. By combining the structural support function with the water containment function in one element, the overall device complexity is minimized while achieving both goals.
Solution Approach 2:
The lineal base is a multi-functional component that simultaneously provides structural support for the panel, contains the anchoring screws within its screw boss receptacle, prevents water intrusion, and maintains aesthetic appearance. This multi-functionality reduces the need for additional separate components, thereby managing complexity effectively.
3Ease of manufacture
If the lineal base is left exposed, then ease of installation is improved, but exterior appearance deteriorates
Solution Approach 1:
The cap is designed to be removable, creating a dynamic system where the lineal base can be accessed for installation and maintenance, then covered for aesthetic purposes. This dynamic configuration allows the system to switch between functional mode (cap removed for screw installation) and aesthetic mode (cap installed for appearance), resolving the contradiction between installation ease and visual appeal.

AI summary
A storm trim for holding a panel over a window for protection against impact of objects carried by wind during a storm. The storm trim includes a lineal cap and a lineal base. The base may be used with a window frame, incorporated into a window frame or be used in glazing surrounds or shutters. The base carries a stacked screw boss to receive and securely hold the anchoring screws that are needed to hold the panel over the window. The anchoring screws do not extend through the lineal base but remain within it. When the storm trim is not in use, the cap covers the lineal base.
