Tool-Free Mounting Rail Locking for Busbar Adapter Repositioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mounting rails for busbar adapters require tools for secure attachment and repositioning, which can be inconvenient and lead to lost screws during handling.
Innovation Solution
A mounting rail design that allows secure attachment and adjustment without tools, utilizing surface structures on the rail and guide rail profiles that engage manually, and spring means for locking and releasing the rail's position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If screws are used to secure the mounting rail to the busbar adapter, then the mounting rail can be securely attached, but the attachment process becomes inconvenient and requires tools
Solution Approach 1:
The mounting rail incorporates spring means that automatically engage with the guide rail profiles when the mounting rail is inserted into the busbar adapter. The spring means exert a closing force that secures the mounting rail to the busbar adapter without requiring external tools or additional fastening operations, making the system self-securing.
2Reliability
If screws are used to secure the mounting rail, then the mounting rail can be firmly fixed, but the screws may get lost during handling
Solution Approach 1:
The invention extracts and eliminates the screws from the system by replacing them with spring means that are integral to the mounting rail structure. The spring means are retained on the mounting rail and automatically engage with the guide rail profiles, preventing any loss of fastening elements during handling while maintaining firm fixation.
3Reliability
If the mounting rail is attached with screws, then the position can be fixed, but repositioning or removing the rail requires tools
Solution Approach 1:
The spring means provide a dynamic securing mechanism where the mounting rail can be easily inserted and secured by manual operation. The spring means can be manually disengaged from the guide rail profiles, allowing the mounting rail to be repositioned or removed without tools. The spring mechanism naturally maintains engagement during normal operation but allows easy release when needed.
4Ease of operation
If a tool-free mounting system is implemented, then handling convenience is improved, but the attachment security may be compromised
Solution Approach 1:
The spring means are formed with curved or elastic structures that provide both ease of manual operation and secure attachment. The elastic deformation of the spring means allows for simple manual engagement and disengagement while maintaining reliable securing force during operation, combining convenience and security.
