Compact Safety Wire Fastening Device with Interlocking Locking Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fastening devices for safety wires on roof equipment lack a compact and secure design, failing to effectively address safety standards and ease of installation.
Innovation Solution
A fastening device with a compact design featuring a holder formed by interlocking members with engagement means, such as protruding sections and corresponding slits, that securely lock the safety wire in place, allowing for easy attachment and secure locking, and optionally includes a pivot mechanism for adjustable mounting angles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional fastening devices are used, then the safety wire can be fastened to roof equipment, but the design is not compact and lacks secure locking capability
Solution Approach 1:
The fastening device is divided into two separate parts: a first part with a first engagement means and a second part with a second engagement means. These parts can be attached to each other to form a complete fastening device, allowing for compact design while maintaining secure locking capability through the interlocking engagement means
Solution Approach 2:
The engagement means are designed with protruding sections and corresponding slits that nest into each other when the first and second parts are attached. This nesting mechanism provides secure locking while maintaining a compact overall device structure
2Ease of operation
If conventional fastening devices are used, then the safety wire can be fastened, but the installation process is not easy
Solution Approach 1:
The first and second parts can be pre-assembled with their respective engagement means positioned for easy connection. The protruding section and corresponding slit are pre-configured to guide the attachment process, making installation straightforward while ensuring secure fastening when properly connected
3Reliability
If the holder structure is expanded to improve security, then locking capability increases, but the device size increases
Solution Approach 1:
The engagement means utilize a radial dimension with protruding sections and corresponding slits arranged in a radius of the holder's inner surface. This dimensional approach allows secure locking through interlocking features without increasing the overall device volume, as the engagement occurs within the existing radial space
