Vertical Sliding Window with Retractable Sash and Integrated Screen
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vertical sliding windows protrude into rooms when opened, limiting space and allowing insects to enter, while existing solutions either provide inadequate protection or compromise insulation and aesthetics.
Innovation Solution
A vertically sliding window system with a self-locking drive mechanism, such as an electric or hydraulic motor, that allows the entire window sash to retract into a chamber, eliminating the need for counterweights and enabling seamless integration of insect screens and shading devices, ensuring complete opening without protrusion and enhanced insulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional pivot windows are used, then the window can be opened, but the opened sashes protrude into the room and restrict freedom of movement
Solution Approach 1:
The patent transitions from horizontal pivoting motion to vertical sliding motion, changing the dimension of movement. The sash moves vertically along guide rails and retracts into a chamber above the window opening, eliminating protrusion into the room and preserving freedom of movement while reducing space occupation.
Solution Approach 2:
The sash is designed to retract completely into a chamber positioned above the window opening when opened. This nesting arrangement allows the sash to be stored within the building envelope, eliminating external protrusion while maintaining full opening capability.
2Area of stationary object
If the window sash is made retractable into a chamber, then the visible opening remains unobstructed, but the chamber requires space that reduces insulation capacity
Solution Approach 1:
The patent employs a pressure frame with linkage mechanisms that apply sealing pressure around the sash periphery. This flexible sealing system maintains effective sealing even when the sash is fully retracted, minimizing energy loss while preserving the full visible opening area.
Solution Approach 2:
The pressure frame and sealing system are pre-positioned and pre-tensioned to ensure optimal sealing contact. This preliminary preparation ensures that when the sash reaches its retracted position, sealing is already established, preventing energy loss without requiring additional space.
3Object-affected harmful factors
If a protective net is attached to a shaft with coil springs, then the net can be deployed, but a hand crank is required and the glass pane may sag and leak
Solution Approach 1:
The protective net is integrated with the sash itself rather than being a separate manually operated system. The net is attached to the sash periphery and automatically deploys with the sash, eliminating the need for hand cranks and complex winding mechanisms while ensuring proper positioning without sagging.
Solution Approach 2:
The protective net function is merged with the sash structure. The net is attached to the sash frame and moves together with it, combining the sealing and insect protection functions into a single integrated system that operates automatically with sash movement.
4Ease of operation
If counterweights are used to hold the sliding window, then the window can be opened, but the counterweights require considerable play within a chamber, limiting insulation space
Solution Approach 1:
The patent removes the counterweight mechanism entirely from the system. Instead, the sash is held and operated using a pressure frame with linkage mechanisms that apply sealing pressure and control sash position. This extraction of counterweights eliminates the need for large chambers and maximizes insulation space while maintaining full opening capability.
Solution Approach 2:
The traditional mechanical counterweight system is replaced with a pressure frame and linkage mechanism system. This substitution uses elastic deformation and mechanical leverage to achieve the same holding and opening functions with minimal space requirements, preserving insulation capacity.
5Ease of manufacture
If a roller blind runs in its own tracks inside the window, then shading can be provided, but a gap remains between the sash and roller blind allowing insects to enter
Solution Approach 1:
The protective net function is merged with the sash structure itself. The net is attached to the sash frame and moves together with it, combining the sealing and insect protection functions into a single integrated system that operates automatically with sash movement, eliminating gaps that would allow insect entry.
Solution Approach 2:
The protective net material and sash frame form a homogeneous, continuous barrier system. The net is tightly integrated with the sash periphery, creating a uniform sealing surface that prevents insect penetration while maintaining the shading function.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution provides a fully retractable window sash that maintains the openness of the visible area, prevents insect entry, and enhances insulation by eliminating gaps, while allowing for adjustable ventilation and protection against driving rain.
Implementation Method 1
at least one self-locking activator in the form of an energy converter for converting an supplied auxiliary energy into a mechanical movement, preferably an electric or hydraulic motor
Implementation Method 2

AI summary
The invention relates to a vertical sliding window as a closure for an opening in the exterior wall of a building, wherein at least one pane of the sliding window can be lowered downwards for opening, into a shallow chamber within a box. The sliding window can be offered as a finished module with the option of integrating insulation and/or designing the facade; furthermore, a roller shutter box can also be integrated, particularly in a thermally insulated form. The range of applications for such a sliding window component extends from single-family homes to high-rise buildings of any conceivable height.
