Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The detection of optically invisible networks, such as gas, electricity, or water networks, is complex and costly due to signal interference from nearby networks, requiring lengthy and tedious insertion of separation members into connection boxes, especially in service galleries or wall boxes, and necessitates storage of numerous separating members.
Innovation Solution
A detection terminal with a protection element that can be easily moved to isolate the electrical connection means from the ground, preventing electromagnetic field propagation and allowing for simple and reliable detection by isolating the network to be detected, without the need for intrusive installation or authorization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separation members are inserted into connection boxes to isolate tracer wires from earth, then electromagnetic field propagation is prevented and detection reliability is improved, but the detection process becomes long and tedious
Solution Approach 1:
The protection element is pre-configured in the detection terminal with electrical connection means that can be quickly connected to the tracer wire, eliminating the need for time-consuming insertion of separate separation members into connection boxes during the detection process
Solution Approach 2:
The invention extracts the isolation function from the connection box and integrates it into a portable detection terminal with built-in protection elements, allowing the terminal itself to provide electromagnetic isolation without requiring modification of existing connection boxes
2Object-affected harmful factors
If separation members are inserted into connection boxes to prevent signal propagation, then electromagnetic interference is reduced, but the operation becomes complex and requires storage of numerous separating members
Solution Approach 1:
The detection terminal incorporates universal protection elements that can be used with any tracer wire configuration, eliminating the need to store multiple types of separation members for different connection box scenarios
Solution Approach 2:
The protection element acts as an intermediary component integrated into the detection terminal, providing electromagnetic isolation through a standardized interface that simplifies the operation compared to inserting various separation members into different connection boxes
3Reliability
If connection boxes are accessed in service galleries or wall boxes for inserting separation members, then isolation can be achieved, but the installation becomes intrusive and requires authorization
Solution Approach 1:
The detection terminal is designed to be self-contained with all necessary isolation components integrated, allowing operators to perform isolation without needing to access or modify existing connection boxes in service galleries or wall boxes
Solution Approach 2:
The invention segments the isolation function from the fixed installation infrastructure (connection boxes) and places it in a portable detection terminal, eliminating the need for intrusive installation in service galleries or wall boxes

Function Achieved in This Case
Enables rapid and accurate localization of optically invisible networks by avoiding electromagnetic interference, improving detection reliability and security, and eliminating the need for extensive setup or storage of separation members.
Implementation Method 1
part of the electrical signal injected into the connection box associated with the optically invisible network to be detected, is likely to propagate, via the earth, in connection boxes associated with other optically invisible networks. Such propagation may involve the creation of an electromagnetic field along the tracer wires
