Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automation technologies face challenges in maintaining continuous communication and energy supply for field units in explosion-hazardous areas, particularly when using radio modules, which require additional energy sources and increase maintenance efforts, and can lead to unintended or manipulated operations due to continuous radio module activation.
Innovation Solution
A measuring transducer supply unit integrating a radio module that can be activated and deactivated via a switch, enabling wireless communication between field units and control units, eliminating the need for physical connection to the 4 to 20 mA current loop, and providing direct energy supply to the radio module, thus ensuring continuous operation and reducing maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a radio module is integrated into the measuring transducer supply unit, then wireless communication capability is improved, but device complexity increases
Solution Approach 1:
The radio module is integrated directly into the measuring transducer supply unit, combining wireless communication functionality with the existing power supply infrastructure. This merging approach enables field units to be operated wirelessly without requiring separate radio devices, thereby improving versatility while managing complexity through functional integration.
2Ease of operation
If the radio module is continuously activated, then ease of operation is improved, but energy consumption increases
Solution Approach 1:
The radio module's activation state is dynamically adjusted based on operational requirements. A switch mechanism allows the radio module to be activated when wireless operation is needed and deactivated when not required, enabling flexible adaptation between wireless and wired operation modes to optimize energy consumption while maintaining ease of operation when needed.
3Ease of operation
If the radio module is always active, then ease of operation is improved, but reliability decreases due to manipulation risk
Solution Approach 1:
The system dynamically controls radio module activation through a switch, allowing operators to enable wireless functionality only when required. This dynamic control reduces the window of opportunity for unauthorized manipulation or inadvertent operation while maintaining ease of operation during authorized use, thereby improving reliability without permanently sacrificing operational convenience.
