Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the standard Bluetooth mesh provision process is used for each node, then the network security and protocol compliance are ensured, but the network establishment time increases significantly
Solution Approach 1:
The patent applies preliminary action by pre-configuring group number information in nodes before provisioning. When a node receives an infrared activation signal, it can immediately generate group keys using its pre-stored group number without requiring complex key exchange procedures, thus reducing provisioning time while maintaining security through pre-established cryptographic parameters
Solution Approach 2:
The patent uses an infrared signal as an intermediary to trigger rapid provisioning. The infrared control apparatus sends activation signals that contain or reference group number information, serving as a mediator between the provisioner and nodes to enable quick group key generation without direct Bluetooth key exchange, thereby reducing time while ensuring protocol compliance
2Reliability
If the standard Bluetooth mesh provision process is executed for multiple nodes, then each node is properly integrated into the network, but the overall provisioning process becomes complex and time-consuming
Solution Approach 1:
The patent merges multiple provisioning operations into a single infrared signal transmission. Instead of executing separate provision processes for each node, the system uses a unified infrared activation signal that triggers simultaneous group key generation across multiple nodes, reducing process complexity while ensuring each node is properly integrated through the common group key mechanism
Solution Approach 2:
The patent enables nodes to perform self-service provisioning by automatically generating group keys when they receive the infrared activation signal. Each node uses its pre-configured group number information to independently generate its group key without requiring manual configuration or complex interaction with the provisioner, simplifying the overall provisioning process while ensuring proper node integration
3Reliability
If individual provision processes are performed for lots of nodes, then each node achieves proper network configuration, but time waste occurs due to repeated complex procedures
Solution Approach 1:
The patent applies preliminary action by pre-configuring group number information in nodes during manufacturing or initialization. This allows nodes to skip the time-consuming key exchange and configuration steps during actual provisioning, as they can immediately generate group keys using their pre-stored group numbers when activated by the infrared signal, thereby improving productivity while maintaining reliable network configuration
Solution Approach 2:
The patent uses the infrared signal as an efficient intermediary to rapidly provision multiple nodes simultaneously. The infrared control apparatus transmits activation signals that trigger group key generation across numerous nodes in parallel, dramatically improving provisioning efficiency compared to sequential individual provision processes while ensuring each node receives proper network configuration through the standardized group key mechanism
