Firefighting Pipe Holder With Guided Pressing Plate Fixation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing firefighting pipe fixing devices are cumbersome and difficult to install due to the need for precise alignment in limited ceiling spaces, especially when connected to sprinklers, making it challenging to securely fix the pipes to square pipes on building ceilings.
Innovation Solution
A firefighting pipe fixing device with a holder having a "" shaped structure, including a "∩" shaped pipe seating parts and a pressing plate guided by pins, allowing for vertical fixation of the pipe to a square pipe, using a fastening screw to press the pipe against the square pipe, facilitating easy insertion and secure fixation without vertical movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the firefighting pipe is fixed using round holes in the upper plate and lower plate, then the pipe can be inserted, but precise alignment is required making installation difficult in limited ceiling spaces
Solution Approach 1:
The fixing device is divided into multiple functional components: holder body, pipe pressing part, pressing plate, and guide pins. This segmentation allows each component to perform its specific function independently, with the guide pins handling alignment and the pressing plate handling fixation, thereby reducing overall installation difficulty while maintaining security
Solution Approach 2:
Guide pins are introduced as intermediary elements between the holder and the pressing plate. These guide pins serve as mediators that automatically align the pressing plate with the holder during installation, eliminating the need for precise manual alignment of the firefighting pipe with round holes while ensuring secure fixation
2Reliability
If the firefighting pipe is connected to a main pipe with a sprinkler mounted, then the sprinkler function is achieved, but the pipe cannot be freely controlled making exact insertion into round holes difficult
Solution Approach 1:
Guide pins act as intermediaries that bridge the gap between the rigid holder structure and the flexible pressing plate. They provide automatic alignment guidance that accommodates the reduced positioning flexibility caused by the sprinkler-mounted pipe connection, allowing the pressing plate to be guided into place without requiring precise pre-alignment of the firefighting pipe
Solution Approach 2:
The pressing plate is designed to be movable relative to the holder body, allowing it to be positioned and adjusted dynamically during installation. This dynamic capability compensates for the reduced adaptability of the firefighting pipe that has a sprinkler mounted on it, enabling easy insertion and secure fixation
3Reliability
If a separate frame is constructed when no proper ceiling structure is available, then the firefighting pipe can be fixed, but the device complexity increases
Solution Approach 1:
The holder body and pressing plate are merged into a single integrated fixing device that can be mounted directly on existing ceiling structures like square pipes. This merging eliminates the need for separate frame constructions, reducing overall device complexity while maintaining reliable fixation capability through the integrated pressing mechanism
