Device for hanging textiles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for hanging textiles, such as curtains, are not tolerant of fluctuations in thickness and generate noise due to the kinematics and metal part interactions, which is undesirable, especially in theatrical settings.
Innovation Solution
The anchor plate is mounted directly on the holding body and coupled to the pressure plate via an adjustable connecting element, forming a four-bar linkage, with the electromagnet's influence maintained across all positions, and elastomers are used to dampen noise, allowing for a compact and silent operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the anchor plate is mounted on the pressure plate with adjustable connection, then the device can adapt to different textile thicknesses, but the system becomes sensitive to thickness fluctuations and folds
Solution Approach 1:
The device is divided into functionally independent segments: the anchor plate is separated from the pressure plate and mounted directly on the holding body, while the pressure plate becomes an independent lever arm. This segmentation allows each component to perform its specific function optimally without interfering with the other, resolving the contradiction between adjustability and reliability.
Solution Approach 2:
The electromagnet acts as an intermediary element that directly connects the anchor plate to the holding body, eliminating the need for mechanical adjustment mechanisms between the anchor plate and pressure plate. This intermediary connection provides stable, noiseless operation while maintaining the ability to accommodate thickness variations through the lever mechanism.
2Device complexity
If traditional metal-to-metal connection is used for the anchor plate and pressure plate, then the structure is simple, but noise is generated during switching
Solution Approach 1:
The mechanical connection between the anchor plate and pressure plate is replaced by an electromagnetic field-based connection. The electromagnet creates a magnetic field that holds the anchor plate in position without physical contact, eliminating metal-to-metal impact and associated noise while maintaining structural simplicity.
Solution Approach 2:
The connection mechanism changes from a mechanical state (metal-to-metal contact) to an electromagnetic state (magnetic field interaction). This parameter change allows the system to maintain holding force while eliminating the harmful noise generated by mechanical impact during switching.
3Adaptability or versatility
If the electromagnet is positioned far from the anchor plate to accommodate thick textiles, then thicker textiles can be held, but the electromagnet's influence decreases
Solution Approach 1:
The system uses a dynamic lever mechanism where the pressure plate can pivot to accommodate varying textile thicknesses. This dynamic adjustment allows the electromagnet to remain in its optimal position close to the anchor plate, maintaining strong electromagnetic influence while still being able to hold thick textiles through the mechanical advantage of the lever system.
Solution Approach 2:
The solution moves the thickness accommodation from the electromagnetic interaction dimension to the mechanical lever dimension. The electromagnet operates in its optimal close-range dimension, while the pressure plate lever provides the additional dimension of mechanical adjustment for thick textiles, separating the two functions spatially and functionally.

AI summary
The invention relates to a device for hanging up textiles, such as curtains, with a holding body (1) which can be attached to a fixed structure, a counter-plate (7) fixed to the holding body (1), and a counter-plate (7) attached to the holding body (1) in an articulated manner Pressure plate (6), the pressure plate (6) forming a clip with the counter-plate (7) to hold the textiles in place, and with an electromagnet (10) which interacts with an anchor plate (8) to close the clip. A particularly low level of noise can be achieved in that the anchor plate (8) is mounted on the holding body (1) and is coupled to the pressure plate (6) by an adjustable connecting element (9), and that the mounting of the anchor plate (8) on the holding body (1) is arranged between the bearing of the pressure plate (6) and the adjustable connecting element (9).
