Twist-Lock Connector Structure to Prevent Rail Channel Migration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing modular rail mounting systems with twist-lock connectors are prone to wobbling and migration due to vibration, requiring frequent adjustments and replacement of worn connectors, which is time-consuming and labor-intensive.
Innovation Solution
A twist-lock fixing system that includes a connector with a stem, a locking tab, and a body section with a flange, where the locking tab bends and unbends to secure the connector in place, limiting rotation and preventing migration within the locking channel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a twist-lock connector is used in a modular rail mounting system, then the component can be quickly attached to the workpiece, but the connector is prone to wobbling and migration due to vibration
Solution Approach 1:
The locking tab is designed to dynamically change shape during the locking process. It bends during insertion to allow movement, then springs back to a locked position that prevents wobbling and migration. This dynamic behavior allows the connector to be quickly attached while achieving reliable vibration resistance.
Solution Approach 2:
The connector is divided into distinct functional segments: an insertion portion for quick entry, a locking tab for securing, and a body section for mounting. This segmentation allows each part to perform its specific function optimally - quick insertion followed by reliable locking.
2Ease of manufacture
If a twist-lock connector is used for mounting, then installation is simplified, but the connector requires frequent replacement due to wear
Solution Approach 1:
The locking tab automatically performs the locking action through its own elastic deformation. When the connector is inserted and rotated, the locking tab bends and springs back to engage with the workpiece, creating a self-locking mechanism that requires no additional fastening steps and reduces wear from manual adjustment.
Solution Approach 2:
The locking tab's physical state changes during operation - it transitions from a straight configuration during insertion to a bent configuration during locking. This parameter change allows the same component to facilitate both easy installation and long-term durability without requiring replacement.
3Reliability
If the locking tab is made resilient to enable bending during rotation, then the connector can lock securely, but the structure becomes more complex
Solution Approach 1:
The locking tab integrates multiple functions into a single element: it serves as both the rotation indicator and the locking mechanism. The same resilient portion that bends during rotation also provides the locking force, eliminating the need for separate components and reducing overall structural complexity.
Solution Approach 2:
The locking tab utilizes a thin, flexible portion that can elastically deform. This flexible element provides the necessary resilience for secure locking while maintaining a simple, lightweight structure that does not require complex mechanisms or additional parts.

AI summary
A twist-lock fixing may include a connector configured for receipt into a locking channel. The connector includes a stem having a first end opposite a second end. The stem includes a locking tab extending from a first side of the stem. The connector includes a head, the head extending from the second end of the stem and spaced apart from the locking tab. The twist-lock fixing may include a body section attaching to the connector at the first end of the stem. The body section includes a flange configured for contacting a first side of the workpiece to limit a longitudinal insertion of the connector into the locking channel.
