Fixing assembly for a shading body
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fixing assemblies for shading bodies, such as curtains, blinds, and shades, are not universally applicable and often require screws that leave holes in walls, limiting tenant choices and causing disputes.
Innovation Solution
A fixing assembly comprising a fixing rail, an elastic fastener, and an extendable rod, where the elastic fastener includes a rod-retaining section and engaging sections that securely attach the rod to the rail without screws, allowing the rod to be easily adjusted and attached between opposite surfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional fixing assemblies use screws to attach the rail to walls, then the installation is stable and reliable, but it leaves screw holes in walls causing damage and limiting tenant flexibility
Solution Approach 1:
The patent replaces the conventional screw-based mechanical fastening system with an elastic fastening system. The elastic fastener uses elastic deformation and friction forces to secure the rod to the rail, eliminating the need for screws that penetrate and damage walls. This substitution maintains installation reliability through elastic retention while avoiding wall damage.
Solution Approach 2:
The patent changes the fastening mechanism from rigid screw connection to elastic deformation-based connection. The elastic fastener utilizes elastic modulus and deformation parameters to create a secure fit without permanent wall modifications. The elastic pieces can deform to accommodate the rod and rail interface, providing reliable retention through parameter-based elastic engagement rather than mechanical penetration.
2Reliability
If conventional fixing assemblies require brackets and screws for installation, then the attachment is secure, but the installation process becomes complex and time-consuming
Solution Approach 1:
The patent merges the functions of brackets, screws, and fastening mechanisms into a single integrated elastic fastener component. The elastic fastener combines the attachment security function previously requiring multiple separate components (brackets for positioning, screws for securing) into one unified element that achieves both positioning and secure attachment through its elastic structure, thereby reducing installation complexity.
Solution Approach 2:
The patent extracts and eliminates the need for separate brackets and screws from the installation system. By designing the elastic fastener to perform both bracket-like positioning and screw-like securing functions simultaneously, the invention removes unnecessary intermediate components, simplifying the overall device structure and installation process while maintaining attachment security.
3Ease of operation
If conventional curtain structures use extendable rods abutting against window frames, then the installation is simple, but it cannot be used with all types of curtains, blinds, and shades
Solution Approach 1:
The patent creates a universal fixing assembly that can accommodate all types of curtains, blinds, and shades. The rail structure combined with the elastic fastener provides a standardized interface that works with various shading body types (cloth curtains, roller shades, Roman shades, Venetian shades, honeycomb shades). The extendable rod system with elastic retention maintains installation simplicity while the rail-fastener combination provides adaptability to different shading product requirements.

AI summary
A fixing assembly for a shading body includes a fixing rail, an elastic fastener and an extendable rod. A slit is arranged at a top side of the fixing rail. The elastic fastener includes a rod-retaining section and two engaging sections. The rod-retaining section is arranged between the two engaging sections. The elastic fastener is engaged with the fixing rail by the two engaging sections. The rod-retaining section is received in the fixing rail and has two positioning portions. The extendable rod is inserted in the rod-retaining section of the elastic fastener through the slit. The two positioning portions abut against an outer periphery of the extendable rod.
