Positioning Error Prevention Hoop for Pipe Fixation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing positioning hoops are difficult to fix accurately on pipes due to voluntary movement in the axial direction, leading to instability and potential disconnection.
Innovation Solution
A positioning error prevention hoop with a curled body, overlapping head and tail sections, a clamping notch, and a limiting member with a through slot and clamping block, which abuts against the pipe to control distance and prevent rotation, ensuring secure fixation and sealing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the hoop is made voluntarily movable on the pipe in the axial direction, then the hoop can be easily installed and adjusted, but it becomes difficult to be held on an appropriate position on the pipe
Solution Approach 1:
The limiting member is pre-installed on the hoop body before installation on the pipe. This preliminary action establishes a fixed reference structure that will later prevent axial movement, resolving the contradiction by preparing the positioning mechanism in advance while maintaining ease of installation through simple assembly steps
Solution Approach 2:
The limiting member acts as an intermediary element between the hoop body and the pipe. It mediates the interaction by providing a clamping structure that engages with the pipe to prevent axial movement, while still allowing the hoop to be installed easily through the fastening component mechanism
2Manufacturing precision
If the hoop body is tightened to be fixed on the pipe, then positioning accuracy is improved, but the hoop body may come off from the pipe due to squeezing between the pipe and limiting member
Solution Approach 1:
The limiting member is designed as a separate, removable component from the hoop body, allowing it to be segmented into distinct functional parts. This segmentation enables the limiting member to be dislodged by squeezing forces while the hoop body remains securely fastened to the pipe, resolving the contradiction by isolating the sacrificial element
Solution Approach 2:
The limiting member is designed as a disposable or easily replaceable component that may be dislodged during tightening. Its temporary attachment to the hoop body allows it to serve its positioning function during installation, then be discarded or removed without affecting the permanent hoop-pipe connection
3Manufacturing precision
If a limiting member is added to control the distance between the hoop body and pipe end, then positioning accuracy is improved, but the device complexity increases
Solution Approach 1:
The limiting member combines multiple functions into a single component: it provides axial positioning control through its clamping structure, serves as a temporary attachment element for the hoop body, and acts as a reference for proper installation depth. This merging reduces the need for separate positioning devices, resolving the contradiction by consolidating functions

AI summary
A positioning error prevention hoop including a hoop body curled to form a sleeving area. After a limiting member is connected on the hoop body, a limiting block of the limiting member abuts against an end of a pipe to control a distance between the hoop body and an end surface of the pipe, such that the hoop body may be secured on an appropriate position. A fastening component is clamped to tighten the hoop body on the pipe. As such, the hoop body will not tend to fall off from the pipe and may also squeeze the pipe and fit it with a connecting piece to form sealing.
