Shading Assembly With Releasable Edge Connection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional shading assemblies for openings with opposite sides, such as rollo systems, often require a winding tube and complex mechanisms, which can be cumbersome and aesthetically unappealing, and do not efficiently manage the movement and storage of flexible shading members.
Innovation Solution
A shading assembly featuring a two-part flexible shading member with an elongate releasable connection device and movable operating member, where storage devices with pressure members allow for seamless detachment and reconnection of shading member parts, eliminating the need for a winding tube and enabling smooth operation between fully covering and partially freeing the opening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a winding tube and complex mechanisms are used in conventional shading assemblies, then the shading member can be wound and unwound, but the device becomes cumbersome and aesthetically unappealing
Solution Approach 1:
The patent removes the winding tube from the system entirely. Instead of winding the shading member around a tube, the invention uses a reel with spools that guide and store the shading member in a linear fashion, eliminating the complex winding mechanism while maintaining the ability to deploy and retract the shading member smoothly
Solution Approach 2:
The shading member is divided into two separate parts that can be independently managed by separate spools. This segmentation allows each part to be stored and deployed independently, simplifying the overall mechanism by removing the need for a single complex winding tube that would have to handle the entire shading member
2Quantity of substance
If a winding tube is used to manage the flexible shading member, then the shading member can be stored, but the mechanism becomes cumbersome and less aesthetically pleasing
Solution Approach 1:
The winding tube is completely extracted from the system and replaced with a reel containing multiple spools. The spools provide linear guidance and storage for the shading member parts, achieving effective storage without the bulk and complexity of a winding tube mechanism
Solution Approach 2:
The spools are designed to rotate and move dynamically as the shading member is deployed and retracted. This dynamic mechanism allows the shading member to be stored efficiently along the length of the spools while maintaining ease of deployment, replacing the static and bulky winding tube
3Stability of the object's composition
If the shading member is made as a single piece, then it provides continuous coverage, but it cannot be detached and stored efficiently in compact spaces
Solution Approach 1:
The shading member is segmented into two separate parts that can be independently stored on separate spools. When deployed, the parts connect to form continuous coverage. When retracted, they can be stored independently, reducing the volume required for storage compared to a single continuous piece that would require winding
Solution Approach 2:
The two shading member parts are designed to nest together when connected, with one part fitting alongside the other during storage. This nesting arrangement allows the combined length of both parts to be stored in a compact configuration along the spools, reducing the overall volume required

AI summary
A shading assembly for shading an opening with at least two opposite opening sides in a structure comprises a flexible shading member which is movable between a position completely covering said opening and a position at least partially freeing said opening. Said flexible shading member is defined by two shading member parts which each have a first edge connected to one of said opposite opening sides and an opposite second edge, wherein said second edges of both shading member parts together define an elongate releasable connection device of the type further comprising a movable operating member which upon movement along said second edges connects or disconnects said second edges.
