Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions for fixing conduits to guide rails often require welding, which can damage the conduits, and lack secure closing systems to prevent accidental dislodging, while also being complex and costly to manufacture and replace.
Innovation Solution
A metal support device with a rigid plate and oblong closing flat bar, featuring a groove and hook mechanism for secure conduit retention, and a pin-based attachment system for easy installation and replacement on guide rails, without the need for welding, and with integrated sealing features.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If welding is used to fix clamps to guide rails, then the fixing strength is improved, but the conduits can be damaged by welding heat and sparks
Solution Approach 1:
The invention extracts the harmful welding process from the fixing system and replaces it with a mechanical pin-based attachment system. The clamp is designed with a pin insertion hole that allows secure attachment to the guide rail without welding, thereby eliminating thermal damage and sparks while maintaining fixing strength.
Solution Approach 2:
The invention introduces a pin as an intermediary element between the clamp and the guide rail. This pin serves as a mediator that transfers the loading from the clamp to the guide rail through mechanical interlocking via the pin insertion hole, avoiding direct welding contact with the conduit while achieving secure fixation.
2Reliability
If a secure closing system is added to prevent conduit dislodging, then the reliability is improved, but the device complexity increases
Solution Approach 1:
The closing system operates on an inversion principle where the clamp starts in an open position for easy conduit insertion, and must be deliberately closed and locked into place. The flat bar is inserted through the conduit and engaged with the hook, creating a secure closed position that prevents accidental dislodging while maintaining simplicity through the natural gravity-assisted closing action.
Solution Approach 2:
The closing system utilizes self-service through gravity-assisted closing. When the flat bar is inserted through the conduit, gravity naturally pulls it downward into the locked position against the stop, eliminating the need for complex actuating mechanisms while ensuring reliable closure and prevention of accidental opening.
3Ease of operation
If the support device is designed for easy replacement at different heights, then the ease of operation is improved, but the fixing security may be compromised
Solution Approach 1:
The support device is segmented into modular components: the clamp body, the flat bar closing element, and the pin attachment system. This segmentation allows the entire assembly to be easily detached from one height position and reattached at another by simply removing and reinserting the pin, maintaining both ease of operation and fixing security through the robust mechanical connection.
4Reliability
If sealing means are integrated into the support device, then the sealing capability is improved, but the manufacturing cost increases
Solution Approach 1:
The sealing function is merged with the existing flat bar closing element. The flat bar serves dual purposes: as the closing mechanism that secures the conduit in place, and as the sealing surface that contacts the conduit to prevent leakage. This integration eliminates the need for separate sealing components, reducing manufacturing cost while improving sealing capability.
