Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vertically moving windows face challenges in achieving a full open surface due to bulky mechanisms and the need for complex housing solutions, which complicates their production and installation, especially when trying to maximize the uncovered area without encroaching on interior space.
Innovation Solution
A window design featuring a frame with a guide system for vertical sash movement, where the sash is motorized and housed below in the closed position, utilizing a muffling system with pulleys and cables actuated by a motorized cylinder, allowing for large amplitude movement without visible mechanisms, and supported by flexible hydraulic connections for reliability and safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a housing for the opening is provided vertically to the surface to be discovered, then the opening can move vertically to maximize uncovered surface, but the mechanism becomes complex and bulky requiring specific building layout
Solution Approach 1:
The opening mechanism is extracted from the vertical housing space and relocated to the bottom of the opening. The motorized displacement means is positioned at the lower level, allowing the opening to be moved vertically without requiring complex mechanisms within the building structure. This extraction simplifies the overall system while maintaining the ability to maximize uncovered surface area.
Solution Approach 2:
The mechanism is positioned in a different spatial dimension - at the bottom of the opening rather than within the vertical housing space. This dimensional relocation allows the mechanism to operate effectively without encroaching on interior space or requiring complex integration into the building structure.
2Ease of operation
If known vertically moving mechanisms are used, then the sash can move vertically, but the mechanisms have not negligible bulk making production and marketing difficult
Solution Approach 1:
The invention employs a motorized cylinder with a reeving system using ropes and pulleys rather than complex mechanical mechanisms. This simpler, more affordable approach replaces bulky, expensive vertically moving mechanisms, making production and marketing easier while maintaining full vertical movement capability.
3Length of moving object
If the opening mechanism is positioned to allow full vertical movement, then large amplitude movement is achieved, but the mechanism becomes visible or encroaches on interior space
Solution Approach 1:
The displacement mechanism is extracted from the visible portion of the window and positioned at the bottom of the opening. The motorized cylinder and reeving system are located where they cannot be seen when the window is closed or open, eliminating the harmful effect of visible mechanisms while maintaining large amplitude vertical movement.
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
This design enables a simple, reliable, and efficient large-amplitude vertical movement, maximizing the open surface area while keeping mechanisms hidden, reducing complexity and cost, and ensuring secure operation with flexible support systems.
Implementation Method 1
The displacement means is thus of easy design, and it can be fixed and supported by all the structures of the openings. Advantageously, said motorized actuator is controlled by a motor and a hydraulic pump that are not fixed, and connected to said actuator by a flexible-type member.
