Snap Fastener with Integrated Hook for One-Handed Curtain Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing snap fasteners for privacy curtains in healthcare settings are difficult to install, remove, and maintain, especially at high elevations, requiring two hands and access to both sides of the curtain.
Innovation Solution
A snap fastener system comprising a snap member with a base, a first engagement portion for mating with another snap member, and a second engagement portion in the form of a hook, allowing for easy removability and secure hanging of curtain sections without needing to access both sides.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional snap fasteners are used to join curtain sections, then the curtain sections can be removably connected, but the fasteners require two hands and access to both sides of the curtain for operation, making installation and maintenance difficult at high elevations
Solution Approach 1:
The patent combines the traditional two-part snap fastener mechanism with an integrated hook structure into a single unified component. The snap fastener body includes both the engagement protrusion for joining curtain sections and an attached hook for securing to the track, merging multiple functions into one device that can be operated with a single hand from one side of the curtain.
Solution Approach 2:
The snap fastener is designed with multi-functionality, serving both to join curtain sections together and to provide a hanging mechanism for securing the curtain to the track. This universal design eliminates the need for separate fastening and hanging components, simplifying operation while maintaining structural integrity.
2Ease of operation
If personnel use ladders or power lifts to access high ceiling areas for curtain installation and maintenance, then they can reach the required heights, but the risk of accidents increases
Solution Approach 1:
The snap fastener with integrated hook enables personnel to install and maintain curtains from ground level or safe working heights. The hook automatically engages with the track when the curtain is lifted into position, and the snap mechanism self-secures the curtain sections together, eliminating the need for personnel to reach high ceiling areas with ladders or power lifts.
3Strength
If traditional fasteners require access to both sides of the curtain for engagement, then secure joining can be achieved, but the operation becomes complex and time-consuming
Solution Approach 1:
The fastener design segments the joining function from the hanging function, with the snap mechanism providing secure joining strength and the integrated hook providing hanging capability. This segmentation allows the fastener to achieve strong curtain section joining while enabling operation from one side only, significantly reducing engagement time compared to traditional two-sided fasteners.

AI summary
A snap member of a fastener includes a base; a first engagement portion extending from the base and configured to engage with a first engagement portion of a mating snap member, the first engagement portion of the snap member including a protrusion defining an axial height, the first engagement portion of the snap member defining a cavity in the protrusion defining an axial depth, an axis of the protrusion and an axis of the cavity being collinear; and a second engagement portion extending from the base, the second engagement portion defining a hook shape.
