Ground Connection Housing With Pre-Laid Conduit for Data Cable Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for connecting data cables to a data cable network require frequent excavation and resurfacing of streets or buildings, which is time-consuming and costly, especially when only a small proportion of residents opt for immediate retrofitting, leading to inefficient and labor-intensive processes for subsequent connections.
Innovation Solution
A connection housing device is installed in the ground with an accessible interior, allowing for the pre-laying of an empty pipe between the data cable branch point and the housing, enabling easy installation and future connection of data cables without the need for repeated excavation, utilizing a plastic molded part with angled connection points and fittings for secure and flexible cable management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If data cables are connected directly from the junction point to each building, then the connection is established, but frequent excavation and resurfacing of streets is required for subsequent connections
Solution Approach 1:
The patent applies preliminary action by pre-installing connection housings with integrated conduits at each building location during the initial street excavation. This allows subsequent cable installations to simply connect to the pre-positioned housings without requiring repeated excavation of the street surface, thus resolving the contradiction between ease of connection and time loss from repeated resurfacing operations.
Solution Approach 2:
The connection housing serves as an intermediary element between the junction point and individual buildings. It provides a permanent access point that eliminates the need for direct street excavation for each connection, allowing cables to be routed through pre-installed conduits to the housing and then into the building, thereby resolving the contradiction by mediating between initial infrastructure work and subsequent connection needs.
2Reliability
If the connection housing is installed deep in the ground, then it is stable and protected, but access for cable installation becomes difficult
Solution Approach 1:
The connection housing is segmented into an underground portion for stability and protection, and an accessible upper portion with an opening for cable installation. This segmentation allows the housing to be embedded deep enough in the ground to be stable and protected from surface damage, while the upper opening remains accessible for cable routing and installation operations.
Solution Approach 2:
The patent resolves the depth-accessibility contradiction by transitioning to another dimension - the opening in the housing provides vertical access from the surface to the interior space. This allows the housing to be positioned deep in the ground for stability while maintaining ease of access through the vertically oriented opening, eliminating the need for horizontal excavation.
3Volume of stationary object
If multiple cables are routed through the same conduit, then space is optimized, but cable management and identification become complex
Solution Approach 1:
The connection housing provides self-service cable management through its interior space that allows cables to be organized, identified, and accessed independently. Multiple cables entering through the conduit can be separated and managed within the housing's interior, with each cable accessible through the opening for identification and connection operations, thus resolving the contradiction between space optimization and management complexity.
