Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wired field devices are used with traditional backup methods, then data can be backed up, but the process is cumbersome and time-consuming requiring on-site equipment and specialized knowledge
Solution Approach 1:
The patent introduces an on-device backup module as an intermediary component that enables automated cloud backup without requiring external operating devices. This module acts as a mediator between the field device data and the cloud server, eliminating the need for laptops or specialized equipment to be physically present at the backup location.
Solution Approach 2:
The backup system implements self-service functionality by integrating the backup module directly into the field device. The device automatically performs backup operations through pre-configured cloud connectivity, eliminating the need for operator intervention, equipment transport, or specialized knowledge to execute backups.
2Reliability
If on-site backup equipment is used, then data backup can be performed, but additional equipment and specialized knowledge are required
Solution Approach 1:
The patent merges the backup functionality directly into the field device by integrating a backup module that combines local data storage, processing capabilities, and cloud communication interfaces. This consolidation eliminates the need for separate backup equipment and reduces overall system complexity.
Solution Approach 2:
The backup module is designed with multi-functionality, serving as both a local data repository and a cloud communication interface. It handles multiple tasks including data buffering, protocol conversion, and wireless communication, replacing what would traditionally require multiple specialized devices.
3Reliability
If traditional backup methods are used, then data can be stored locally, but centralized storage and future-proof compatibility are not achieved
Solution Approach 1:
The patent transitions data storage from a single local dimension to a multi-dimensional architecture by implementing both local buffering and cloud-based centralized storage. This dimensional expansion ensures data security through redundancy while providing adaptability to evolving cloud infrastructures and communication protocols.
