Refrigeration Control Unit for Multi-Device Parameter Configuration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Configuring refrigeration systems is challenging due to the need for specialized knowledge and skills, as individual configuration of operating parameters can lead to incorrect settings, especially for new or infrequent operators, and existing methods only allow for single-device configuration at a time.
Innovation Solution
A method where a control unit selects and configures one device, then automatically sets operating parameters for other devices based on stored data, allowing for correct system operation without requiring operators to know valid parameters for each device, with manual override options for adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If individual configuration of operating parameters is performed for each device, then the operator can configure each device independently, but the configuration may be incorrect and requires special skills and knowledge
Solution Approach 1:
The configuration process is segmented into two distinct phases: manual configuration of selected devices by the operator, and automatic configuration of remaining devices by the control unit based on stored system data. This segmentation allows the operator to focus only on devices requiring manual input while the system handles the rest automatically, reducing errors and skill requirements.
Solution Approach 2:
The refrigeration system performs self-configuration through the control unit, which automatically determines and sets operating parameters for unconfigured devices based on pre-stored system data and relationships. This self-service capability eliminates the need for operators to possess extensive knowledge of all device parameters and their interdependencies.
2Adaptability or versatility
If individual configuration of operating parameters is performed for each device, then each device can be configured separately, but the process is time-consuming and requires special skills
Solution Approach 1:
The configuration task is divided between manual and automatic processes. The operator manually configures only those devices requiring specific input, while the control unit automatically configures the remaining devices. This segmentation dramatically reduces configuration time while preserving the flexibility to handle both routine and exceptional configuration scenarios.
Solution Approach 2:
The system performs preliminary configuration automatically based on pre-stored data before requiring any manual input from the operator. By pre-configuring devices that can be determined from stored system relationships, the system reduces the time the operator needs to spend on configuration tasks while maintaining adaptability for devices requiring manual adjustment.
3Ease of operation
If only one device is configured at a time, then the configuration process is simple for each device, but the overall system configuration is inefficient
Solution Approach 1:
The control unit merges the configuration of multiple devices into a single integrated process. After the operator configures one or more devices manually, the control unit automatically configures additional devices based on the configured devices and stored system relationships, thereby combining multiple configuration tasks into one efficient operation that maintains simplicity while improving productivity.
Solution Approach 2:
The control unit serves multiple functions: it acts as both a receiver of manual configuration input and an automatic configuration engine for remaining devices. This multi-functionality allows the system to handle both simple individual device configuration and comprehensive system-wide configuration through a single integrated process, improving overall efficiency without sacrificing operational simplicity.
Data Source
AI summary
The invention relates to a method for configuring, on a control unit, operating parameters of a plurality of devices of a refrigeration system. A user selects on the control unit, among the plurality of devices of the refrigeration system, a first device to configure. Information of valid configurable operating parameters of the first device is provided on the control unit. The user selects at least one of the valid configurable operating parameters of the first device, thereby configuring the first device. Information stored about operating parameters of other devices of the refrigeration system, based on the configuration of the first device, is then provided on the control unit. Finally, the user confirms, on the control unit, one or more operating parameters of one or more of the other devices, thereby configuring the one or more other devices. The invention also relates to a control unit and a refrigeration system.
