Window Sash Structural Sealing and Accessory Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional sash structures for doors and windows face limitations in aesthetics, assembly time, costs, and thermal sealing, with existing modifications not fully addressing weight reduction, component minimization, and adaptability to existing counterframes without invasive changes.
Innovation Solution
A sash design featuring a structural sealing component with a rigid profile having a closed base side and flaps forming a channel, along with an anchoring rib for enhanced mechanical sealing, allowing adaptation to various glass dimensions and frame types with reduced components and assembly complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a traditional sash structure with uprights and crosspieces is used, then structural strength and sealing are ensured, but weight, assembly time, and costs increase
Solution Approach 1:
The patent removes the traditional uprights and crosspieces from the sash structure, extracting only the essential functional elements. The metal profile is reduced to minimal tubular sections positioned only where accessories (hinges, handles, locks) need to be mounted, eliminating unnecessary structural components while maintaining strength where required.
Solution Approach 2:
The sash is segmented into functional zones: the double glazing unit itself, minimal metal profile sections for accessory mounting, and structural component zones for sealing and support. This segmentation allows each element to perform its specific function efficiently without the overhead of a complete traditional frame structure.
2Strength
If a traditional sash structure with uprights and crosspieces is used, then structural strength and sealing are ensured, but assembly time and costs increase
Solution Approach 1:
Multiple functions are merged into fewer components. The metal profile serves both as structural support and as the mounting base for accessories. The structural component serves both sealing and structural support functions. This reduction in component count directly reduces assembly time and complexity.
Solution Approach 2:
The metal profile and structural component are designed to be multi-functional, serving both structural and accessory-mounting purposes, eliminating the need for separate dedicated mounting brackets and frames.
3Adaptability or versatility
If the frame is made asymmetrical to adapt to different glass dimensions, then adaptability increases, but structural sealing and mechanical strength are reduced
Solution Approach 1:
The sash design is made dynamic and adaptable through the use of adjustable elements. The structural component can be positioned at different locations along the perimeter, and the metal profile sections can be placed where needed, allowing the same basic design to adapt to various glass dimensions and configurations while maintaining structural integrity.
Solution Approach 2:
The structural component is strategically positioned only where needed for sealing and support, with varying thickness and positioning along different edges. This allows optimal sealing at critical locations while maintaining adaptability to different glass sizes, rather than requiring a completely asymmetrical frame design.
4Adaptability or versatility
If accessory zones are added to the frame for mounting hardware, then functionality increases, but device complexity and manufacturing costs increase
Solution Approach 1:
The accessory mounting function is merged directly into the metal profile structure. The tubular profile itself serves as the mounting surface for hinges, handles, and locks, eliminating the need for separate mounting brackets, plates, or additional structural elements.
Solution Approach 2:
The metal profile is designed as a universal mounting solution that can accommodate various accessories at various positions along its length, providing versatile accessory mounting capability without requiring different components for different hardware types.

AI summary
Described is a sash for doors or windows comprising a first (2) and a second (3) sheet of glass positioned facing each other and parallel to each other at a mutual distance (D); a spacer and joining element (4) interposed between two inner surfaces (2a, 3a) facing each other of the two sheets of glasses (2, 3) to define a first closed inner perimeter zone or chamber (5) and a second open outer perimeter zone or cavity (6) for each side defined by the pair of sheets of glass (2, 3); a structural sealing/adhesion component (7) applied along the outer perimeter defined by the cavity (6); the structural component (7) occupies a volume (P) designed to permit its contact at least with the spacer element (4) and with a part of the inner surfaces (2a, 3a) of the two sheets of glass (2, 3), the sash (1) also comprises at least an element (8) for housing accessory components (9a, 9b, 9c, 9d) for supporting and/or operating the sash (1) associated with the structural component (7), for each side defined by the first and second sheet of glass (2, 3); each element (8) is comprised of a rigid profile having, in cross section, at least one closed base side (9) and two flaps (10, 11) each formed by a stretch (12) perpendicular to the base side (9) and a recessed stretch (13), parallel to the base side, to form a channel with an opening (14); the rigid profile is associated with the structural component (7) at least along the outer surface of the base side (10).
