Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If Bluetooth and ANT controllers communicate using separate protocol formats, then each controller can maintain its own protocol integrity, but communication efficiency decreases and bottlenecks occur due to format conversion requirements
Solution Approach 1:
The patent implements a universal Host Controller Interface (HCI) message format that can carry both Bluetooth and ANT protocol data. The HCI message structure includes a protocol identifier field that indicates whether the payload contains Bluetooth or ANT data, allowing a single interface to handle multiple protocol types efficiently without requiring separate conversion paths for each protocol
Solution Approach 2:
The patent introduces an intermediary HCI layer that sits between the Bluetooth controller and ANT controller. This intermediary format acts as a common language that both controllers can understand, eliminating the need for direct format conversion between Bluetooth and ANT protocols and improving communication throughput
2Speed
If direct communication between Bluetooth and ANT controllers is implemented, then communication speed increases, but protocol compatibility issues arise and data processing becomes complex
Solution Approach 1:
The patent segments the communication interface into distinct layers: the HCI message format layer and the protocol-specific payload layer. The HCI layer handles universal message routing and formatting, while the payload layer contains protocol-specific data structures. This segmentation allows fast direct communication while maintaining protocol compatibility through structured data organization
Solution Approach 2:
The patent uses parameter changes in the HCI message format to accommodate different protocols. By including a protocol identifier parameter and adjusting the payload structure based on the identified protocol type, the system achieves both high-speed direct communication and protocol compatibility without complex conversion logic
3Adaptability or versatility
If multiple protocol formats are supported simultaneously, then system versatility improves, but processing overhead increases and bottlenecks occur
Solution Approach 1:
The patent performs preliminary action by including a protocol identifier in the HCI message header that allows the receiving controller to immediately identify the protocol type before processing the payload. This preliminary identification enables the receiver to prepare the appropriate processing routine in advance, reducing processing overhead and avoiding bottlenecks when handling multiple protocol formats
Data Source
AI summary
A system and method using ANT and/or ANT+ protocols for one or more ANT and/or ANT+ applications. The system can include a Bluetooth interface and a Host Controller Interface (HCI) that are configured to process incoming and outgoing ANT and/or ANT+ messages from/to one or more ANT and/or ANT+ enabled devices. The ANT and/or ANT+ messages can be communicated to one or more ANT and/or ANT+ enabled devices utilizing a Bluetooth transceiver. The Bluetooth interface and the HCI can be configured to wrap one or more ANT and/or ANT+ messages with a header and/or to remove a header from one or more wrapped ANT and/or ANT+ messages. The header can be an HCI compatible header.
