Narrow Rail Snap-Connection System Using Sharp-Edge Deformation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional rail systems for hanging objects require wide rails to snap onto mounting heads, making it difficult to use narrow rails and resulting in small, hard-to-mount mounting heads and vulnerable connecting hooks.
Innovation Solution
A narrow rail system with a sharp knife edge for snap connection, integrated mounting heads with screws or nails for easy installation, conical projections for enhanced load-carrying capacity, and locking mechanisms with sleeves for connecting hooks to prevent detachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If the rail is made narrow, then the aesthetic appearance and space utilization are improved, but the rail cannot be properly snapped onto mounting heads
Solution Approach 1:
The mounting head features a localized sharp knife edge at the groove boundary that concentrates the snapping force on a small area, enabling reliable connection despite the narrow overall rail width. This local quality change allows the rail to be narrow while maintaining connection reliability.
Solution Approach 2:
The groove boundary transitions from rounded edges in prior art to a sharp knife edge geometry. This parameter change in edge geometry enables the snap connection to work with narrow rails by creating a precise cutting action that deforms the rail wall locally without requiring the rail to be wide.
2Area of stationary object
If the mounting head is made small to accommodate narrow rails, then the aesthetic appearance is improved, but the mounting head becomes difficult to fix to the wall
Solution Approach 1:
The mounting head and fixing screw are merged into a single integral unit. This combination allows the small mounting head to be easily installed by simply driving the integrated screw into the wall, eliminating the difficulty of separately fixing small mounting heads while maintaining the aesthetic benefit of small size.
3Length of moving object
If the connecting hook is made thin to match the narrow rail, then the aesthetic appearance is improved, but the connecting hook becomes vulnerable to impact and cleaning
Solution Approach 1:
The connecting hook includes a locking means that preemptively prevents detachment caused by impact or cleaning forces. The locking mechanism engages with the rail before any harmful forces can cause the thin hook to become detached, providing preliminary protection against the vulnerability inherent in thin hook design.
4Length of moving object
If the rail wall is made thin for narrow rails, then the aesthetic appearance is improved, but the rail wall cannot deform sufficiently for snapping
Solution Approach 1:
The sharp knife edge at the groove boundary creates a localized deformation zone in the rail wall. This local quality change allows the rail wall to be thin overall while still providing sufficient deformability at the specific location where the knife edge contacts the rail, enabling the snapping action to succeed despite the narrow rail dimensions.

AI summary
The invention relates to a rail system for hanging objects such as paintings, prints, curtains and the like. The rail system comprises a rail (9) provided with a longitudinally extending recess (10) having a rounded edge (14a) and a sharp edge (14b), as well as mounting heads (11), each provided with a tangentially extending groove (13) and with an integral fixing screw or fixing nail (12), which can be fixed to a wall in a row. The rail (9) can be suspended from the grooves (13) with its rounded edge (14a) and be snapped into position, causing the sharp edge (14b) to deform slightly.
