Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for detecting optically invisible networks, such as gas, electricity, or water networks, require access to closed environments and authorization, making them difficult and costly, especially when connection boxes are inside service galleries or manholes.
Innovation Solution
A detection terminal with a protective conductive body that allows direct connection of an electric signal generator, eliminating the need for access to closed environments and authorization, using the conductive properties of the protection part for electromagnetic detection without damaging the network infrastructure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If connection boxes are arranged inside service galleries or manholes, then network security is improved, but access difficulty increases and requires authorization
Solution Approach 1:
The invention moves the connection box from a two-dimensional interior space (inside service galleries or manholes) to a three-dimensional exterior position (above ground level). This dimensional transition allows the connection box to be accessible from the surface while maintaining its protective enclosure, eliminating the need for authorization to access interior spaces while preserving network security through the enclosed design.
2Ease of operation
If connection boxes are placed in public accessible areas, then ease of access is improved, but risk of damage increases
Solution Approach 1:
The invention employs a robust enclosed shell structure that protects the connection box components from environmental factors and unauthorized interference. The enclosure acts as a protective barrier that allows the device to be placed in public accessible areas while preventing damage from weather, accidental contact, or vandalism, thus enabling easy access without increasing damage risk.
3Reliability
If authorization procedures are required for detection, then network security is improved, but detection time increases
Solution Approach 1:
The invention positions the connection box in a location that is accessible from the beginning of the detection process, eliminating the preliminary step of obtaining authorization to access restricted areas. The connection box is pre-configured in a publicly accessible location, allowing detection operations to commence immediately without time-consuming authorization procedures, while network security is maintained through the enclosed protective design.
