Solution Overview
Problem
Existing systems for retrieving measurement data from field devices require manual selection or intervention, which is inefficient when multiple devices are distributed across various locations, such as in a warehouse with multiple tanks.
Innovation Solution
A mobile display device equipped with a sensor arrangement, processing unit, and communication unit that captures environment data to automatically identify and select the relevant field device, allowing for wireless retrieval of measurement data without user intervention, using a digital map and position sensors to determine the device's location and orientation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual selection of field device is required, then system complexity is reduced, but ease of operation deteriorates
Solution Approach 1:
The system automatically identifies the relevant field device using sensor data (camera, microphone, position sensors) and environment data analysis without requiring manual user input. The mobile display device performs autonomous device selection based on captured environmental information, eliminating the need for users to manually search or select from multiple field devices.
Solution Approach 2:
The patent replaces manual mechanical selection operations with automated sensor-based detection and data processing. Instead of users physically navigating or manually selecting devices, the system uses camera images, audio signals, position data, and processing algorithms to automatically identify and select the target field device.
2Productivity
If automatic device selection is implemented, then productivity is improved, but device complexity worsens
Solution Approach 1:
The system divides the automatic device selection task into multiple independent components: sensor data capture (camera, microphone, position sensors), environment data acquisition, data processing and analysis, field device identification, and measurement data retrieval. Each component operates independently but contributes to the overall automated selection process, improving productivity while managing complexity through modular architecture.
Solution Approach 2:
The patent introduces environment data and sensor data as intermediary elements that bridge the user and the field device selection process. These intermediaries carry information about the surrounding environment and device locations, enabling automatic selection without direct user-device interaction, thus improving productivity while the complexity is managed through the intermediary data layer.
3Adaptability or versatility
If multiple field devices are distributed across various locations, then adaptability is improved, but ease of operation worsens
Solution Approach 1:
The mobile display device is designed with multi-functional capabilities, integrating camera, microphone, position sensors, processing unit, and communication unit into a single device. This universal device can automatically identify and retrieve data from any field device in the distributed network, maintaining ease of operation while adapting to multiple locations and device types.
Solution Approach 2:
The patent adds spatial and environmental dimensions to the field device selection process by incorporating position sensors, camera images, and environment data. Instead of simple one-dimensional device lists, the system operates in multi-dimensional space considering location, orientation, and environmental context, enabling users to access distributed devices naturally through their physical context rather than manual searching.
