Retaining Bracket With Serrated Inserts for Separable Conduit Fixing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing retaining brackets for conduits, such as electrical wiring and fluid piping, fail to effectively prevent lateral and transverse movement and are difficult to separate from the conduit without damaging it, especially when made from the same material and using ultrasonic welding.
Innovation Solution
A retaining bracket with conduit holding parts made from a different material than the conduit, featuring serrated inserts that provide a secure grip and allow for easy separation, and a design with two parallel conduit holding parts to securely attach and align conduits, enabling effective fixation and easy disassembly without damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the retaining bracket is made from the same material as the conduit and fixed by ultrasonic welding, then the fixation strength is improved, but the conduit cannot be separated without damage
Solution Approach 1:
The retaining bracket is divided into two distinct material components: the bracket body made of one material and the insert made of the same material as the conduit. This segmentation allows the insert to be welded to the conduit while the overall assembly remains separable through breakage of the bracket body away from the conduit.
Solution Approach 2:
The insert acts as an intermediary element between the retaining bracket and the conduit. It provides the welding interface while being protected from damage during separation, as the bracket body is designed to break away from the conduit rather than the insert or conduit themselves.
2Adaptability or versatility
If the retaining bracket is made from the same material as the conduit, then the material compatibility is improved, but the alignment during fixing is difficult
Solution Approach 1:
Different parts of the retaining bracket have different material properties: the insert matches the conduit material for welding compatibility, while the bracket body uses a different material that provides better mechanical properties for alignment and positioning features.
3Reliability
If the bottom surface of the insert is serrated, then the grip on the conduit is improved, but the manufacturing complexity increases
Solution Approach 1:
The serrated surface creates mechanical interlocking with the conduit through friction and geometric engagement, preventing lateral and transverse movement. This mechanical grip is achieved through simple geometric features rather than complex manufacturing processes.
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
The solution provides secure fixation and prevents movement of conduits while allowing for easy separation without damage, accommodating various conduit materials and sizes, and ensuring alignment during the fixing process.
Implementation Method 1
ultrasonic welding process is applied along the contact surfaces of the conduit and the holding part of the retaining bracket
Implementation Method 2
the bottom surface of the insert (4) is serrated such that the insert (4) has a good grip on the outer surface of the conduit (6)
