Problem

Existing base stations installed above ground face issues such as water intrusion, inappropriate installation positions, weak signal strength, and poor heat dissipation when installed underground, leading to operational malfunctions.

Innovation Solution

An underground base station design featuring an outer shell assembly with a sealing assembly that provides waterproofing and communication protection, a fiber assembly for connectivity, and a cover assembly with an antenna module, allowing for both water and air-based heat dissipation solutions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If the base station is installed underground, then radiation concerns are reduced, but heat dissipation becomes difficult

Engineering Contradiction:
Improveradiation impactVSAvoidheat dissipation
Core Design Contradiction:
Object-affected harmful factorsVSTemperature

Solution Approach 1:

The heat-generating communication equipment is separated from the above-ground antenna module and placed in the underground waterproof cabinet. The cabinet incorporates dedicated heat dissipation channels that provide thermal pathways for heat removal while maintaining the underground installation configuration.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The heat dissipation system utilizes airflow channels and ventilation pathways integrated into the waterproof cabinet structure. Air circulation is established through controlled openings and ducts that allow heat removal while preventing water ingress.

Inventive Principle:
Principle #29Pneumatics and hydraulics

2Object-affected harmful factors

If the base station is installed underground, then aesthetics are improved, but signal strength is weakened

Engineering Contradiction:
Improveaesthetic impactVSAvoidsignal strength
Core Design Contradiction:
Object-affected harmful factorsVSReliability

Solution Approach 1:

The antenna system is positioned in a different spatial dimension (above ground through penetration) relative to the main equipment (underground). This dimensional separation allows the antenna to maintain optimal signal radiation capabilities while the equipment cabinet remains aesthetically pleasing when buried.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

A signal transmission pathway serves as an intermediary that connects the underground equipment with the above-ground antenna. This mediator ensures strong signal transmission while allowing the equipment to be installed underground for aesthetic reasons.

Inventive Principle:
Principle #24Intermediary (Mediator)
