Hook structure for positioning a curtain
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional curtain structures have irregularly spaced hanging rings, causing curtain fabrics to form uneven waves and pleats, affecting their aesthetic appearance and practicality.
Innovation Solution
A hook structure with a rope fastening module that maintains uniform distance between adjacent hooks, ensuring the curtain fabric remains in a regular wavy form by embedding fasteners into engaging spaces of carriers, with adjustable hooks and rope length for custom fit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If hanging rings are used with non-fixed spacing, then the curtain structure is simple and easy to install, but the curtain fabric forms irregular waves and uneven pleats affecting aesthetic appearance
Solution Approach 1:
The hanging ring is segmented into a hook body and a carrier that can relatively move against each other. The carrier is further divided into a first portion and a second portion connected by a flexible section, allowing independent adjustment of spacing while maintaining overall structural integrity. This segmentation enables fixed spacing between adjacent carriers without complicating the overall installation process.
Solution Approach 2:
The hook structure incorporates dynamic elements where the carrier can move relative to the hook body along the curtain rod. The flexible section connecting the first and second portions of the carrier allows the structure to adapt to different installation scenarios while maintaining uniform spacing. This dynamic capability resolves the contradiction between fixed spacing requirements and ease of installation.
2Shape
If hanging rings are spaced at fixed intervals, then the curtain fabric maintains uniform pleat depth and regular wavy form, but the structure becomes more complex with additional positioning components
Solution Approach 1:
The hook body and carrier are merged into a single integrated structure where the carrier is formed as an extension of the hook body. The flexible section is integrated within the carrier structure itself rather than being a separate component. This merging approach achieves uniform spacing functionality without significantly increasing structural complexity.
Solution Approach 2:
The carrier serves multiple functions: it provides the hanging function, maintains fixed spacing, allows relative movement along the rod, and creates uniform pleats. The flexible section simultaneously provides structural connection and enables adjustment. This multi-functionality reduces the need for additional positioning components, resolving the contradiction between uniform shape maintenance and structural simplicity.
3Ease of operation
If the curtain fabric is allowed to move freely on the curtain rod, then the operation is simple and smooth, but the curtain fabric produces different curvatures and pleat depths due to unequal distances between hanging rings
Solution Approach 1:
The uniform spacing of carriers along the curtain rod is predetermined during installation, establishing consistent pleat depths before the curtain is used. The flexible section is pre-configured to allow the necessary range of motion while maintaining these predetermined spacing relationships. This preliminary action ensures both smooth operation and consistent pleat formation throughout the curtain's lifecycle.
Solution Approach 2:
The system allows parameter changes in the form of the flexible section's degree of flexibility, which can be adjusted to balance between operational smoothness and pleat consistency. By optimizing this parameter, the curtain can move freely for easy operation while the carriers maintain stable, uniform spacing to ensure consistent pleat depth. This parameter optimization resolves the contradiction between ease of operation and stability of composition.

AI summary
A hook structure for positioning a curtain and combining a curtain fabric with connecting portions includes hooks and a rope fastening module. Each hook has a hook body, an elastic hook portion extending from the hook body, and a carrier connected to the hook body. A passing-through space between the elastic hook portion and the hook body is provided for inserting the connecting portion, and the carrier has an engaging space. The rope fastening module includes fasteners and a rope connected to the fasteners, each fastener is embedded into the engaging space, so that the distance between two adjacent fasteners of the curtain fabric is maintained by the rope, and the curtain fabric is maintained in a uniform and regular wavy form.
