Switching Device Slide Mechanism for Secure Hat Profile Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical installation switching devices, such as miniature circuit breakers, face challenges in securely mounting wide and heavy devices onto hat profile mounting rails, and there is a need for a simplified mechanism to hold the movable lug in a position remote from the rail for easy insertion and removal.
Innovation Solution
The slide mechanism, with a base plate and lateral edge strips, is designed to fit within guide grooves on the housing, featuring latching contours between the removal and fixing ends, and includes stop lugs and a guide lug to securely hold the device and prevent twisting, allowing for secure mounting and easy removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional slide mechanism is used for mounting the switching device, then the device can be installed on the hat profile rail, but wide and heavy devices cannot be securely held
Solution Approach 1:
The slide is divided into multiple functional segments: a base plate for structural support, lateral skirts for engagement with guide grooves, and a stop lug for positioning. This segmentation allows each component to perform its specific function optimally, enabling the slide to securely hold wider and heavier devices while maintaining the ability to accommodate different device sizes through the same basic structure.
2Ease of operation
If the movable lug is held close to the hat profile rail, then the device is securely fastened, but insertion and removal become difficult
Solution Approach 1:
The slide is designed as a movable component that can dynamically change position between a retracted state (for easy insertion/removal) and an engaged state (for secure fastening). The spring mechanism provides the dynamic force to automatically position the stop lug in the guide groove during insertion, and the operator can manually retract the slide during removal. This dynamic capability resolves the contradiction between ease of operation and fastening security.
3Reliability
If the slide is made wide to encompass the entire device width, then heavy devices can be secured, but the device complexity increases
Solution Approach 1:
Instead of making the entire slide wide and complex, the invention applies width and engagement features only where locally needed: the lateral skirts engage with the guide grooves at specific locations, and the stop lug makes localized contact with the hat profile rail. This localized application of structural features achieves secure holding capability without requiring the entire slide structure to be unnecessarily complex or wide.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution ensures secure mounting of wider and heavier devices while allowing the movable lug to be held in a remote position, facilitating easy insertion and removal, and prevents twisting of the device when snapped onto the hat profile rail.
Implementation Method 1

AI summary
The device has a shell (2) whose wide side (4) is retained in a guide slot (12) by arranging a guide plate (7) in vertical movement. The slot is extended between a removing end (13) and a location end (14) and provided with a clamping lock (15). The clamping lock is arranged between the removing end and the location end such that edge plate is connected into the clamping lock in a middle position between the removing end and the location end. The guide plate is retained in a removing part, and a stopping bump (8) and a cover-shaped support rail are unlocked in the removing part.
