Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If remote observation is implemented in a non-networked production facility, then security and confidentiality are improved, but system complexity and infrastructure requirements worsen
Solution Approach 1:
The system divides the observation function into separate components: mobile devices for video capture, hub device for coordination, and observer devices for viewing. This segmentation allows each component to remain simple while the overall system achieves secure remote observation capabilities without requiring full network infrastructure.
Solution Approach 2:
The hub device acts as an intermediary between mobile devices and observer devices, coordinating video feed routing and observer authentication. This intermediary approach enables secure remote observation in non-networked environments by centralizing control functions without requiring complex peer-to-peer networking.
2Productivity
If physical presence of observers is reduced, then operational efficiency is improved, but verification and guidance capabilities worsen
Solution Approach 1:
The system creates visual copies of the manufacturing process through video feeds from mobile devices, allowing remote observers to verify operations without physical presence. This copying approach maintains verification capability while eliminating the need for observers to be on-site, thereby improving operational efficiency.
Solution Approach 2:
The system enables real-time feedback between observers and operators through the video communication channel. Observers can provide guidance and verification remotely, and operators can receive immediate feedback, maintaining the interactive verification process without requiring physical presence.
3Loss of information
If selective access to confidential regions is implemented, then information security is improved, but system complexity worsens
Solution Approach 1:
The system applies different access rights to different spatial regions of the manufacturing facility. Each observer is granted access to specific confidential regions based on their credentials, while other regions remain inaccessible. This local quality approach enables selective information security without requiring complex global access control mechanisms.
Solution Approach 2:
The system changes the access parameter (visibility of confidential regions) based on observer credentials. By dynamically adjusting what regions are visible to each observer, the system achieves selective information security through parameter changes rather than complex access control logic.

AI summary
A method includes: via a user interface of a hub device, receiving a first set of user credentials associated with a first operator, the hub device connected to a set of mobile devices; accessing a first operator schedule defining a first scheduled manufacturing operation and a first observer of the first scheduled manufacturing operation, the first observer characterized by a first set of observer credentials; detecting disconnection of a first mobile device in the set of mobile devices from the hub device, the first mobile device associated with a first device ID; in response to detecting disconnection of the first mobile device from the hub device, associating the first device ID with the first operator; and routing a first video feed from the first mobile device to the first observer based on the first device ID and the first set of observer credentials.
