Dual Sash Window Assembly with Telescopic Link Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing window assemblies fail to simultaneously provide significant thermal conductivity resistance, windload resistance, storm-driven debris impact resistance, sound transmission barrier, air and water infiltration resistance, forced entry resistance, and protection from infrared and ultraviolet light while being convenient and economical to use.
Innovation Solution
A dual sash insulated window assembly with a main support frame and parallel spaced sash units made of extruded plastics, featuring telescoping link members, gears for simultaneous movement, and a lock system that secures and seals the sash frames to the main frame, enhancing thermal efficiency, windload resistance, and sound barrier with dual insulated glass panels and additional dead air space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple performance features (thermal resistance, windload resistance, debris impact resistance, sound barrier, infiltration resistance, forced entry resistance) are added to window assemblies, then protection and efficiency are improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The window assembly is divided into multiple sash units (inner sash unit and outer sash unit) that can be independently positioned and secured. Each sash unit contains insulated glass panels within sash frames, creating segmented functional zones that collectively provide comprehensive protection while maintaining manageable complexity through modular design
Solution Approach 2:
The inner sash unit is nested within the outer sash unit, with both positioned within recesses of the main support frame. This nested configuration allows multiple protective layers to be integrated in a compact arrangement, providing enhanced protection without proportionally increasing overall assembly complexity
2Temperature
If dual sash units with insulated glass panels are used, then thermal efficiency and sound barrier are improved, but manufacturing cost and device complexity increase
Solution Approach 1:
Identical sash frames and glass units are used for both the inner sash unit and outer sash unit. This homogeneity allows for standardized manufacturing processes, bulk material purchasing, and simplified assembly procedures, thereby reducing manufacturing costs while maintaining the thermal efficiency benefits of dual insulated glass panels
3Ease of operation
If telescoping link members and gears are added for simultaneous movement, then operational coordination is improved, but device complexity increases
Solution Approach 1:
The telescoping link members and gears are integrated into a unified mechanical connection system that couples the inner sash unit and outer sash unit. This merged mechanism ensures simultaneous movement of both sash units through a single operational input, improving coordination while consolidating multiple components into a cohesive assembly that manages complexity
4Reliability
If lock system with handle member is implemented, then security and sealing are improved, but device complexity increases
Solution Approach 1:
The lock system with the handle member serves multiple functions: it secures both the inner sash frame and outer sash frame to the main support frame, and it compresses both sash frames against the main frame to create weather seals. This multi-functional design provides enhanced security and sealing without requiring separate mechanisms for each function, thereby managing overall complexity

AI summary
A main support frame is formed from sections of a plastic extrusion and has opposite side portions with peripheral recesses receiving an inner sash unit and outer sash unit each having a frame formed from sections of a plastic extrusion and supporting an insulated glass unit. Hinges support the dual sash units for pivotal movement between open and closed positions, and gear connected telescopic link members connect the main frame to the sash frames for simultaneous movement. A lock system includes a handle on the inner sash unit for moving straps with studs on the sash frames through a connector mechanism mounted on the main frame for simultaneously locking and releasing both sash units and for releasing only the inner sash unit. A screen and/or mini-blind can be supported between the sash units, and the window system with dual sash units may be constructed in various forms.
