Segmented Curtain Rod Assembly With Hidden Fasteners
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The connecting sections of long curtain rods, which are typically fixed with bolts, cause friction and deformation of the curtain fabric over time, affecting its service life and aesthetics.
Innovation Solution
A curtain rod design featuring a main rod with connecting members that include limiting and connecting sections, where fixing components are housed in avoidance sections to reduce fabric friction, and the use of fixing rivets and bolts for secure assembly, along with two rotation methods for ease of operation and safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fixing components (bolts) are used to secure connecting sections to the main rod, then the structural reliability is improved, but the curtain fabric undergoes friction and deformation affecting its service life and aesthetics
Solution Approach 1:
The fixing components (bolts and rivets) are extracted from the traditional external mounting position and relocated to an internal avoidance section within the rod body structure. This extraction removes the harmful contact between fixing components and curtain fabric while preserving the structural reliability function.
Solution Approach 2:
The fixing components are nested within the avoidance section of the rod body, creating a hierarchical structure where the bolts and rivets are contained inside the rod's internal cavity. This nesting allows the fixing mechanism to function without exposing harmful elements to the curtain fabric.
2Shape
If the curtain rod is designed as a single long piece, then the aesthetic integrity is improved, but the transportation and installation difficulty increases
Solution Approach 1:
The curtain rod is segmented into multiple rod body sections that can be separately manufactured and transported. The connecting sections with limiting sections enable these segments to be joined together through the avoidance section, achieving both ease of transportation and aesthetic integrity when assembled.
3Ease of manufacture
If fixing components are exposed on the main rod, then the assembly simplicity is improved, but the curtain fabric aesthetics and service life are degraded
Solution Approach 1:
The fixing components are extracted from the visible external position and placed within the internal avoidance section. This maintains assembly simplicity through straightforward bolt and rivet installation while eliminating the harmful visual and physical impact on the curtain fabric.

AI summary
A curtain rod comprises a main rod, a fixing base and a rotary base. The fixing base and the rotary base are respectively disposed at both ends of the main rod; the main rod comprises a plurality of rod body sections and a connecting member configured to connect two adjacent rod body sections; the connecting member comprises a limiting section and two connecting sections symmetrically arranged on both sides of limiting section; the rod body section is correspondingly provided with a connection cavity for the engagement with the connecting section; shape of the limiting section matches cross-sectional shape of the rod body section; the connecting section is provided with a fixing component for securing rod body section; and side wall of the rod body section is recessed in a direction toward an axis of rod body section to form a fitting section and a avoidance section.
