Solution Overview

Problem

Existing curtain gliders face challenges in providing a secure fit, easy insertion and removal, and efficient production, with many designs failing to ensure stability and ease of handling.

Innovation Solution

A glider design featuring a T-shaped head, neck, and hanging area, allowing for a rotating and tilting movement for insertion and removal, and a one-piece construction for robustness, combined with a solid-state joint for secure hold and smooth operation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the glider uses a traditional support projection and catch design, then the structure is simple, but the secure fit in the rail cannot be guaranteed

Engineering Contradiction:
Improvesecure fitVSAvoidstructure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The glider employs a dynamic insertion mechanism where the support projection can rotate between a first position (for insertion) and a second position (for secure engagement). This dynamic movement allows the glider to transition from a compact state during insertion to a locked state during operation, achieving secure fit without complex multi-component structures

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The glider structure is divided into functional segments: the support projection with rotation capability, the catch mechanism, and the engagement surfaces. This segmentation allows each component to perform its specific function efficiently while maintaining overall structural simplicity

Inventive Principle:
Principle #1Segmentation

2Ease of operation

If the glider requires support projections spaced from support shoulders or catch overcoming, then the structure can be simple, but insertion and removal become difficult

Engineering Contradiction:
Improveinsertion and removalVSAvoidsecure fit
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The support projection is designed to rotate dynamically during insertion and removal operations. During insertion, it rotates to a first position that facilitates easy entry into the rail. During removal, it rotates to a second position that enables straightforward extraction, while maintaining secure fit during normal operation

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The glider performs preliminary rotation of the support projection to the first position before insertion, preparing the structure for easy entry. This preliminary action ensures that no force is required to overcome spaced projections or catches during normal insertion and removal operations

Inventive Principle:
Principle #10Preliminary action

3Ease of operation

If the guide section is made compressible and resilient, then insertion is enabled, but the glider does not provide a secure hold and is difficult to handle

Engineering Contradiction:
ImproveinsertionVSAvoidsecure hold
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

Instead of making the entire guide section compressible and resilient, the invention applies elasticity locally at the support projection, which can dynamically change its engagement state. The main body of the glider remains rigid for secure holding, while only the support projection exhibits elastic behavior during insertion and removal operations

Inventive Principle:
Principle #15Dynamics

4Reliability

If the glider is designed for secure fit and high load-bearing capacity, then reliability is improved, but insertion and removal may become more difficult

Engineering Contradiction:
Improvesecure fitVSAvoidinsertion and removal
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The support projection rotates between a first position (facilitating easy insertion) and a second position (enabling easy removal), while the glider body maintains rigid engagement surfaces for secure fit and high load-bearing capacity during operation. This dynamic reconfiguration allows easy operation without compromising reliability

Inventive Principle:
Principle #15Dynamics

AI summary

Device for hanging curtains or the like on a C-shaped rail (1) having a guide slot (12) flanked by two supporting shoulders (11). The device consists of a slider (2) having three areas: a suspension area (3) shaped as a hook or eyelet or the like, a T-shaped head area (5) for fastening the device to the rail (1), and a neck area (4) located therebetween. The T-shaped head area (5), the neck area (4), and the suspension area (3) are designed such that the slider (2) can be removed from the guide slot (12) by a rotating and tilting movement.
