Enclosed Multiprotocol Antenna System for Grid Node
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for monitoring electrical utility equipment face design challenges in protecting antennas from outdoor elements while maintaining functionality, as they are exposed to weather and interference, and require protocol-specific designs that complicate installation and maintenance.
Innovation Solution
A grid node with an enclosed multiprotocol antenna system, featuring a hollow outer shell made of non-metallic materials and an inner shell forming a ground plane, which houses a motherboard and multiprotocol antenna array, allowing for communication with multiple wireless protocols without being removed from the site, and includes a method of construction that positions the antenna array in a space defined by the shells to prevent interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the antenna is exposed externally to transmit or receive data, then wireless communication functionality is achieved, but the antenna is exposed to weather, contamination, and external interference
Solution Approach 1:
The patent implements a nested antenna structure where multiple antenna elements are positioned within concentric cylindrical housings. The antennas are nested within the housing structure rather than being externally exposed, allowing the system to achieve wireless communication while protecting the antenna elements from environmental factors such as weather and contamination.
2Object-affected harmful factors
If the housing provides adequate protection for the system, then protection from weather and contamination is achieved, but the antenna functionality may be compromised
Solution Approach 1:
The patent applies local quality by creating specific openings or apertures in the housing at strategically located positions that allow antenna signals to pass through while the rest of the housing maintains protective enclosure. The housing structure is designed with differentiated regions: protected internal components and controlled signal transmission zones that maintain both protection and functionality.
3Reliability
If the system is designed to support particular protocols and standards, then compliance with mechanical and electrical requirements is achieved, but the system lacks adaptability to multiple protocols
Solution Approach 1:
The patent implements a universal communication interface design where the system can support multiple wireless communication protocols through a standardized connector and interface architecture. The housing and internal components are designed to accommodate different protocol requirements while maintaining a consistent mechanical and electrical interface, allowing the system to adapt to various protocols without requiring complete redesign.
