Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If Bluetooth LE technology is used to control device connections, then power consumption is reduced and connectivity is stabilized, but device complexity increases due to lack of user interface
Solution Approach 1:
The patent introduces a control device as an intermediary that manages connection control services between Bluetooth devices. This control device handles the complexity of connection management, bonding information, and device state monitoring, thereby reducing the complexity burden on devices without user interfaces while maintaining reliable connectivity through centralized coordination.
Solution Approach 2:
The control device performs multiple functions including connection establishment, bonding management, device state acquisition, and coordination with other wireless network interfaces. This multi-functionality consolidates complex operations into a single device, enabling simple devices to maintain stable connectivity without requiring complex onboard management capabilities.
2Ease of operation
If connection control services are implemented for devices without user interface, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The control device serves as an intermediary that provides connection control services to devices without user interfaces. It manages bonding information, monitors device states, and coordinates connections through Bluetooth LE technology, enabling operation of complex connection management functions on simple devices.
Solution Approach 2:
The control device autonomously manages connection control services, bonding states, and device state information without requiring user interface interactions. It self-coordinates connection establishment and maintenance, allowing devices without user interfaces to operate independently while maintaining ease of operation through automated management.
3Reliability
If bonding information and connection information are managed centrally, then reliability is improved, but loss of information may occur
Solution Approach 1:
The control device continuously acquires bonding information and connection information from connected devices, maintaining updated records of device states and connection statuses. This feedback mechanism ensures reliable information management while preventing data loss through ongoing synchronization with connected devices.
Solution Approach 2:
The control device proactively acquires and maintains bonding information and connection information before connection issues arise. By preliminarily establishing and monitoring bonding states and device states, the system prevents information loss and maintains reliability through advance preparation and continuous monitoring.
