Solution Overview
Problem
Existing pipeline detection devices are cumbersome due to their non-detachable, integrated handheld structure, making them inconvenient to transport and store.
Innovation Solution
A modular positioning device comprising a host machine and a detachable detection part with a buckle connection system, including an ejector pin assembly for electrical connection and signal feedback, allowing for compact storage and easy carrying.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the positioning device adopts an integrated handheld structure, then the device maintains structural integrity and stability, but the device occupies large space and is inconvenient to transport and carry
Solution Approach 1:
The positioning device is divided into two separable parts: a host machine and a detection part. The detection part can be detached from the host machine when not in use, reducing the occupied space and improving portability. The buckling connection structure ensures reliable connection during use while allowing separation for storage and transport.
2Volume of moving object
If the detection part is detachably connected to the host machine, then the device becomes convenient to transport and store, but the connection stability and electrical connection reliability may be compromised
Solution Approach 1:
The buckling connection structure is pre-designed with positioning features and corresponding receptacles. The ejector pin assembly is pre-positioned to automatically engage with the positioning feature when the detection part is connected to the host machine, ensuring stable mechanical and electrical connections without requiring complex assembly procedures.
3Reliability
If the ejector pin assembly is used for electrical connection, then the signal feedback reliability is improved, but the device complexity increases
Solution Approach 1:
The ejector pin assembly combines multiple functions into a single component: it provides both mechanical positioning/buckling support and electrical signal feedback. By integrating the electrical connection function into the mechanical buckling structure, the device achieves reliable signal feedback without adding separate complex electrical connection mechanisms.
