Sealed Housing Dome Antenna for Wireless Data Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems face challenges in transmitting data from within a sealed filter housing to an external monitoring or test device, particularly due to internal conditions like fluid flow, pressure, or temperature, which make the use of wires impractical.
Innovation Solution
The system employs an electrically isolated housing dome acting as an antenna to facilitate signal transmission between the internal RFID tags and an external RFID reader, using configurations such as a monopole or dipole antenna setup, or utilizes a gasket with a channel for electrical connections to bypass the need for direct contact and wires.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If wires are used to transmit data from within the filter housing to an external device, then data transmission is achieved, but the sealed environment is compromised and reliability under internal conditions deteriorates
Solution Approach 1:
The patent replaces the mechanical wire-based data transmission system with an electromagnetic field-based RFID system. The RFID tag stores data internally without requiring physical connections, and the reader wirelessly retrieves data through electromagnetic fields, eliminating the need for wires that would compromise the sealed housing environment.
Solution Approach 2:
The patent introduces an intermediary electromagnetic field as the medium for data transmission between the RFID tag inside the sealed housing and the reader outside. This intermediary allows data to pass through the housing wall without requiring physical penetration or wire connections, maintaining the integrity of the sealed environment.
2Loss of information
If wires are installed inside the housing to connect internal devices, then data transmission is enabled, but device complexity and installation difficulty increase
Solution Approach 1:
The patent eliminates the complex internal wiring structure by replacing it with a wireless RFID system. The RFID tag is simply attached to or integrated with the internal device, requiring no wiring, while the reader externally accesses data through electromagnetic fields, significantly reducing device complexity.
Solution Approach 2:
The patent extracts the data transmission function from the mechanical wiring system and relocates it to a wireless electromagnetic field system. This separation allows the internal housing to remain simple and sealed, while data transmission capabilities are provided externally through the RFID reader.
3Power
If the housing is made electrically conductive to serve as an antenna, then signal transmission efficiency is improved, but electrical isolation requirements may be compromised
Solution Approach 1:
The patent applies local quality by making only specific portions of the housing electrically conductive to serve as antenna elements, while other portions remain electrically isolating. This allows the housing to provide signal transmission efficiency where needed while maintaining electrical isolation properties where required, through spatially differentiated material properties.
