Underground Street Cabinet Layout for Footpath Access Without Obstruction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional street cabinet arrangements fail to provide sufficient adaptability and access to contents of communications networks without obstructing footpaths, particularly when large shaft modules are required, as they often necessitate extensions into the footpath.
Innovation Solution
A modular street cabinet arrangement featuring a base portion with a main base and projection base, both with longitudinal and lateral wall portions that form a continuous frame, allowing the box portion to be supported outside the footpath while maintaining access without obstructing the path, with the base portion disposed underground and the projection base extending parallel to the footpath to support the box portion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a relatively large shaft module with several covers is required, then the extension is implemented starting from the box module and into the footpath, but the footpath is obstructed
Solution Approach 1:
The base portion is configured to extend in a transverse direction perpendicular to the footpath direction, allowing the shaft module to achieve large volume without extending along the footpath. The longitudinal wall portions extend transverse to the footpath while the cover extends longitudinal to the footpath, creating a L-shaped footprint that maximizes volume while minimizing footpath obstruction.
Solution Approach 2:
The base portion is divided into longitudinal wall portions and lateral wall portions that can be independently configured. The lateral wall portions extend transverse to the footpath direction, creating segments that allow the structure to achieve large volume while the cover portion can be arranged to extend longitudinal to the footpath without obstructing it.
2Ease of operation
If the box portion is positioned to provide access from the footpath, then access to contents is enhanced, but the footpath is obstructed by the box portion
Solution Approach 1:
The cover is configured with its longitudinal axis extending in the longitudinal direction of the footpath, creating a local arrangement where the access portion faces the footpath for enhanced accessibility, while the main body of the shaft module extends transverse to the footpath to minimize obstruction. This local optimization allows access without significant footpath blockage.
3Adaptability or versatility
If modular elements are used to form the base portion, then adaptability to varying geometric shapes and volumes is achieved, but device complexity increases
Solution Approach 1:
The longitudinal wall portions and lateral wall portions are designed as universal modular elements that can be combined in various configurations to create different geometric shapes and volumes. The same basic modular components serve multiple functions: forming the base structure, providing support for the box portion, and enabling adaptability to different application requirements through simple recombination.

AI summary
A street cabinet arrangement may include a box portion configured to house contents of a communications network therein and a base portion configured to be disposed underground and having a portion that is configured to support the box portion. The base portion may include a projection base portion configured to extend from the main base portion. At least a portion of the main base portion may be configured to be disposed underground beneath a footpath with a longitudinal dimension of the main base portion and a longitudinal dimension of the projection base portion extending parallel to one another and to the footpath such that at least a portion of the projection base portion is disposed outside of the footpath and configured to support the box portion outside of the footpath with an access portion of the box portion configured to extend parallel to the footpath and facing the footpath so as to provide enhanced access to contents of the box portion from the footpath without obstructing the footpath with the box portion.
