Existing field devices in industrial process facilities lack visual indicators and transient protection, making it difficult for maintenance personnel to verify the power state and installation status of devices, and they do not provide adequate protection against harsh environments.
Innovation Solution
An electrical connector apparatus with a housing, electrical feedthrough subassembly, and visual indicators like LEDs to indicate power state, along with transient protection circuitry and a flameproof barrier, providing a compact solution for field devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If field devices are installed in harsh industrial environments without visual indicators, then the device structure remains simple, but maintenance personnel cannot easily verify power state and installation status
Solution Approach 1:
The patent employs visual indicators that change color or illuminate to indicate the power state and installation status of field devices. LEDs or other visual indicators provide clear visual feedback (e.g., green for powered, red for unpowered) enabling maintenance personnel to quickly verify device status without complex procedures or opening enclosures.
2Reliability
If field devices lack transient protection circuitry, then the device complexity is reduced, but the devices are vulnerable to damage from electrical surges and transient events in harsh environments
Solution Approach 1:
The patent incorporates transient protection circuitry that provides beforehand cushioning against electrical surges and transient events. The protection circuitry is pre-installed in the connector housing to absorb and dissipate electrical transients before they can damage sensitive field device components, ensuring reliability in harsh industrial environments.
3Productivity
If manual checking of each field device is required without visual indicators, then safety regulations can be followed, but maintenance time and labor costs increase significantly
Solution Approach 1:
The visual indicators on the connector housing enable the field devices to self-report their power state and installation status. Maintenance personnel can quickly scan multiple devices and identify those that are powered or unpowered without manual checking, allowing the system to serve its own monitoring function and significantly reducing maintenance time and labor requirements.
4Ease of operation
If enclosures are opened without visual power indicators, then workers can access devices, but the risk of working on powered equipment increases
Solution Approach 1:
The visual indicators provide immediate feedback regarding the power state of field devices through the connector housing. Workers can observe the visual indicators (e.g., illuminated LEDs) from outside the enclosure to determine whether devices are powered before attempting to open enclosures, providing safety feedback without requiring enclosure opening and eliminating the need to manually check powered equipment.
