Transmitter Cable Gland Connection Module for Sealed Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Transmitters in potentially explosive applications face challenges with interface sealing, requiring high demands for tight sealing to prevent explosive hazards, and existing solutions do not adequately ensure simple and secure external operation.
Innovation Solution
A connection module with an operating element is integrated into the cable gland, which can be easily and securely inserted into the transmitter housing, utilizing threaded armor cable glands or self-sealing threading, and may include additional sealing elements and wireless interfaces for secure and remote operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If an interface is provided in the transmitter housing for operating the display unit, then ease of operation is improved, but tight sealing is compromised
Solution Approach 1:
The patent combines the operating element and the cable gland into a single integrated connection module. This merging eliminates the need for separate interfaces while maintaining both operational accessibility and tight sealing, as the integrated module can be sealed together with the cable gland structure.
Solution Approach 2:
The connection module acts as an intermediary component that bridges the operating element and the sealed housing. It provides a controlled interface that allows user interaction while maintaining the protective sealing through its integration with the cable gland system.
2Ease of operation
If multiple interfaces are provided for operation and control, then ease of operation is improved, but the number of potential weak points increases
Solution Approach 1:
The patent merges multiple operating elements into a single connection module that is integrated with the cable gland. This consolidation reduces the number of separate interfaces and potential weak points while maintaining full operational functionality through the unified module design.
3Reliability
If a threaded armor cable gland is used, then tight sealing is improved, but device complexity increases
Solution Approach 1:
The patent combines the threaded armor cable gland with the connection module containing the operating element into a single integrated unit. This merging simplifies the overall device structure by eliminating separate components while maintaining the protective sealing benefits of the threaded armor cable gland.
