Fenestration Frame Glazing Stop Interior Re-glazing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Re-glazing of fenestration units from an exterior space can be unsafe and expensive due to height, location, or environmental factors, making it difficult and costly.
Innovation Solution
A fenestration unit design that allows for re-glazing from an interior space, featuring a frame with a glazing stop and sealing members, where the glazing stop is releasably coupled to the frame and sealing members are adhesively or non-adhesively attached to facilitate removal and reinstallation without cutting, reducing the need for exterior access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If re-glazing is performed from exterior space, then glazing unit can be replaced, but safety risks increase and cost increases due to height, location, or environmental factors
Solution Approach 1:
The patent inverts the conventional re-glazing approach by enabling access to the glazing unit from the interior space rather than requiring exterior access. The glazing stop is designed with a removable cover and coupling mechanism that allows interior access to the glazing unit, eliminating the need for workers to safely access exterior surfaces at height or in difficult locations.
Solution Approach 2:
The glazing stop is segmented into multiple components including a removable cover, coupling elements, and sealing members. This segmentation allows the cover to be removed from the interior for maintenance access while the main glazing stop remains installed in the frame, enabling repair without exterior access.
2Ease of repair
If re-glazing is performed from exterior space, then glazing unit can be replaced, but time consumption increases and efficiency decreases
Solution Approach 1:
The glazing stop includes pre-installed coupling elements and sealing members that are designed for quick release and reinstallation from the interior. The removable cover provides immediate access to the glazing unit without requiring time-consuming exterior access procedures, and the coupling mechanism allows for rapid detachment and reattachment of the glazing unit.
3Stability of the object's composition
If glazing stop is permanently fixed to frame, then structural stability is maintained, but re-glazing from interior space is prevented
Solution Approach 1:
The glazing stop transitions from a static permanent fixture to a dynamic system with movable components. The removable cover can be detached from the frame, and the coupling elements can be released, allowing the glazing stop to change configuration from a stable fixed state to an accessible open state for interior re-glazing operations.
Solution Approach 2:
The cover is extracted as a separate removable component from the glazing stop assembly. This extracted cover provides access to the interior space where the glazing unit can be reached, while the main body of the glazing stop remains coupled to the frame to maintain structural stability.
4Reliability
If sealing members are adhesively coupled, then sealing effectiveness is improved, but removal requires cutting increasing complexity
Solution Approach 1:
The sealing system is segmented into multiple sealing members positioned at different locations (first sealing member between glazing unit and frame, second sealing member between glazing unit and glazing stop). This segmentation allows selective removal and replacement of individual sealing members from the interior without affecting the entire assembly, reducing complexity compared to cutting through a single permanent seal.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design reduces the time, cost, and safety risks associated with re-glazing by enabling interior access and removal of glazing components, allowing for safer and more efficient replacement of glazing units.
Implementation Method 1
the first sealing member is adhesively coupled to the engagement surface of the frame and non-adhesively coupled to the first side of the glazing unit
Implementation Method 2
the second sealing member is adhesively coupled to the second side of the glazing unit and the first engagement face of the glazing stop
Implementation Method 3
the first sealing member and the second sealing member comprise foam and are at least one of air-permeable and moisture-blocking
