Camera Component Communication Protocol Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing camera component communication systems, such as those using the CAN bus protocol, are not designed for high transmission frequencies, limiting data rates and flexibility, and requiring costly upgrades to implement newer, more efficient protocols.
Innovation Solution
The camera component's communication device is configured to automatically check for compatibility with both a first protocol (e.g., CAN) and a second protocol (e.g., SPE) and establish communication using the second protocol if both devices support it, while remaining compatible with devices that only support the first protocol.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the camera component uses an existing communication protocol like CAN bus, then compatibility with existing systems is maintained, but data transmission rate and flexibility are limited
Solution Approach 1:
The communication device dynamically selects between different communication protocols (CAN bus or SPE) based on the capabilities of the connected device. The control unit performs protocol compatibility checks and automatically switches to the appropriate protocol, making the system adaptive rather than static. This resolves the contradiction by allowing high-speed SPE protocol when available while maintaining backward compatibility with CAN bus protocol.
Solution Approach 2:
The system changes the communication parameter (protocol type) based on detected conditions. The control unit checks whether the connected device supports SPE protocol, and if so, switches from CAN bus protocol to SPE protocol. This parameter change enables higher data transmission rates when possible while maintaining compatibility when necessary.
2Productivity
If the camera component upgrades to a newer communication protocol for higher data rates, then transmission speed improves, but acquisition costs increase
Solution Approach 1:
The communication device is designed with multi-functionality to support both CAN bus protocol and SPE protocol. By integrating dual protocol support into a single communication device, the system can achieve high-speed transmission when needed without requiring separate hardware for each protocol, thereby reducing overall acquisition costs while maintaining high productivity capability.
Solution Approach 2:
The control unit acts as an intermediary that manages protocol selection and conversion. It performs compatibility checks and automatically selects the appropriate protocol, allowing the system to leverage high-speed SPE protocol when available without manual configuration or additional cost, while seamlessly falling back to CAN bus protocol when necessary.
3Adaptability or versatility
If the communication device supports multiple protocols, then adaptability improves, but device complexity increases
Solution Approach 1:
The control unit merges the functionality of multiple protocol handlers into a single integrated component. Rather than having separate communication devices for CAN bus and SPE, the control unit combines both protocol support within one device, performing compatibility checks and automatic protocol selection. This merging approach maintains high adaptability while reducing overall system complexity.

AI summary
A camera component has a communication device for transmitting control signals and/or status signals, said communication device comprising a control unit and at least one electrical terminal, wherein the electrical terminal has at least two energy supply contacts and at least two signal contacts, and wherein the control unit is configured to perform the following steps when the communication device is connected to a further communication device of a further camera component via the electrical terminal:performing a first check whether a communication in accordance with a first protocol is possible with the further communication device;then, performing a second check whether a communication in accordance with a second protocol is also possible with the further communication device; andin the event of a positive result of the second check, establishing a communication with the further communication device in accordance with the second protocol.
