Architectural Window Covering Rail Cord Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing coverings for architectural openings, such as windows and doors, often have complex constructions that make them difficult to attach and detach, and may have cords that protrude into the opening, causing interference with the mechanism of movement and appearance.
Innovation Solution
A covering system with a pleated material and cords that are integrated into the rail assembly, using a metal tape with an arcuate cross-section and a guide rail with complementary cross-sections to maintain the material in its plane, allowing for easy removal and adjustment, and a magnetic strip to secure the metal tape, ensuring the cords remain within the structure and do not protrude into the opening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If cords are extended from the first rail to a fixed rail on the opposite side of the architectural opening, then the material is maintained in its plane, but the cords protrude into the opening and interfere with the mechanism of movement and appearance
Solution Approach 1:
The cords are extracted from the external space and integrated within the rail assembly structure. The second rail incorporates internal passages that contain the cords, removing them from the architectural opening space while maintaining their functional connection between rails.
Solution Approach 2:
The cords are nested within the second rail structure. The rail assembly contains the cords internally through defined passages, creating a nested configuration where the cord system is housed within the rail framework rather than extending externally.
2Stability of the object's composition
If a complex construction is used to maintain material stability, then the material remains in its plane, but the attachment and detachment becomes difficult
Solution Approach 1:
The system is segmented into modular components: first rail, second rail, material, and cords as separate but interconnected elements. This segmentation allows the assembly to be constructed by joining discrete parts and detached by separating them, simplifying both manufacturing and installation while maintaining structural stability.
Solution Approach 2:
The rail assembly serves multiple functions: it supports the material, maintains its plane through cord integration, provides structural framework, and enables easy attachment/detachment. This multi-functionality consolidates what would otherwise require separate complex mechanisms into a unified system.
3Stability of the object's composition
If cords are provided to maintain material in its plane, then the material stability is improved, but the device complexity increases
Solution Approach 1:
The cord system and rail assembly are merged into a single integrated structure. The cords are incorporated within the second rail, combining the support function and the structural framework into one unified assembly, thereby reducing overall system complexity while maintaining material stability.
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 simpler and more efficient attachment and detachment mechanism, maintains the material within its plane, prevents cord interference, and enhances the appearance by keeping the metal tape and cords neatly within the structure, facilitating easy installation and removal while maintaining the material's plane during use.

AI summary
A covering for an architectural opeing including a first rail (10) having opposite ends, a second rail (12) having opposite ends, the second rail (12) being parallel to the first rail (10) and movable towards and away from the first rail (10), a collapsable and extendable material (14) secured to and extending between the first rail (10) and the second rail (12), the first and second rails (10,12) defining a plane within which the material (14) extends, a metal tape (22) extending from said one end of the first rail (10) to said one end of the second rail (12), extending from said one end of the second rail (12) through and along the second rail (12) to the other end of the second rail (12) and extending away from the other end of the second rail (12) for securement to an adjacent edge of the architectural opening; and a cord (16) extending between the first rail (10) and the second rail (12) for retaining the material (14) within said plane, the cord (16) extending from a position intermediate the opposite ends of the first rail (10) in a direction substantially perpendicular to the first and second rails (10,12) to a position intermediate the opposite ends of the second rail (12). The cord (16) has a first end secured at the first rail (10) and a second end secured at the second rail (12), the second end being movable along the second rail (12) with movement of the metal tape (22) through and along the second rail (12) such that movement of the second rail (12) towards or away from the first rail (10) results in movement of the metal tape (22) through and along the second rail (12) together with movement of the second end of the cord (16) along the second rail (12) and, thus, decrease or increase respectively of the length of the cord (16) extending between the first rail (10) and the second rail (12).
