Fastening system for a decorative valance of a roller blind and a decorative valance of a curtain provided with a fastening system
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fastening systems for roller blinds require numerous components, increasing manufacturing costs and complicating installation due to the need for multiple pieces to attach the roller shade and decorative valance to walls or ceilings.
Innovation Solution
A dual-function anchoring element with a coupling region for the wall or ceiling and a second region for supporting drive means, integrated with guide means to attach side panels, reduces the number of pieces needed and allows for easier assembly by supporting both the decorative valance and rotating roller with a single element.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional fastening systems use multiple separate pieces and components to attach the decorative valance and roller, then the attachment is reliable and secure, but the manufacturing costs increase and installation becomes more cumbersome
Solution Approach 1:
The patent combines multiple separate components (attachment piece for the valance and attachment piece for the roller) into a single integrated anchoring element. This anchoring element has a body portion that attaches to the wall/ceiling and extends into the housing to support the roller, eliminating the need for multiple separate attachment components while maintaining secure attachment of both the decorative valance and the roller.
Solution Approach 2:
The anchoring element serves multiple functions simultaneously: it attaches the decorative valance to the wall or ceiling, supports the rotating roller inside the housing, and provides structural connection between these components. This multi-functional design reduces the total number of components needed in the system.
2Reliability
If traditional fastening systems use numerous components and additional attachment elements, then the attachment is secure, but the installation time increases and assembly becomes more difficult
Solution Approach 1:
By merging the attachment functions into a single anchoring element, the installation process is simplified. Instead of installing multiple separate pieces and coordinating their assembly, the installer works with one integrated component that handles both valance and roller attachment, significantly reducing installation time and complexity.
3Reliability
If traditional fastening systems require additional attachment elements to couple the roller to the decorative valance, then the connection is secure, but the manufacturing costs increase due to more molds and equipment needed
Solution Approach 1:
The patent eliminates the need for separate attachment pieces for the roller by integrating the roller support function directly into the anchoring element. The body portion of the anchoring element extends into the housing to directly support the roller, removing the need for additional attachment components and reducing manufacturing complexity and costs.
Solution Approach 2:
The anchoring element is designed as a universal component that handles multiple attachment and support functions, reducing the total number of different component types that need to be manufactured. This reduces the number of molds and manufacturing equipment needed, thereby lowering production costs.
