Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle communication interface (VCI) and diagnostic tool combinations require manual pre-configuration of IP addresses for wireless connections, which is time-consuming and complex, limiting the ability to add, substitute, or remove devices within a wireless network.
Innovation Solution
A wireless communication system that allows vehicular diagnostic tools to automatically detect and connect with VCIs, using multicast queries and dynamic IP address assignment, enabling seamless detection and connection of VCIs proximate to the diagnostic tool without manual configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual pre-configuration of IP addresses is used for wireless connections between VCI and diagnostic tool, then connection reliability is improved, but device complexity and setup time increase
Solution Approach 1:
The system enables automatic IP address assignment and device discovery through multicast queries. The diagnostic tool automatically queries for VCIs in the wireless network and receives dynamic IP addresses without manual configuration, making the system self-configuring and eliminating setup complexity while maintaining connection reliability
Solution Approach 2:
The system performs preliminary network discovery and IP assignment actions automatically before the user needs to use the diagnostic tool. By pre-establishing the wireless connection parameters through automatic discovery protocols, the system eliminates the need for manual pre-configuration while ensuring reliable connections are ready when needed
2Stability of the object's composition
If manual pre-configuration of IP addresses is used, then connection stability is improved, but productivity and ease of operation deteriorate
Solution Approach 1:
The automatic discovery mechanism allows the diagnostic tool and VCI to self-configure their wireless connection parameters. The system automatically performs device discovery, IP address assignment, and connection establishment without requiring technician intervention, thereby improving productivity while maintaining connection stability through automated protocol handshaking
Solution Approach 2:
The system dynamically changes IP address parameters automatically through multicast-based discovery protocols. Instead of fixed manual configuration, the system allows IP addresses to be dynamically assigned and reconfigured as devices are added or removed from the wireless network, improving setup efficiency while maintaining stable connections through automated parameter management
3Reliability
If manual pre-configuration is required, then network security is improved, but adaptability and ease of operation worsen
Solution Approach 1:
The system transitions from static manual IP configuration to dynamic automatic IP assignment. Devices can be freely added or removed from the wireless network, and the system dynamically reconfigures IP addresses and connection parameters automatically, providing high adaptability while maintaining security through automated authentication and connection management protocols
4Ease of operation
If automatic detection is implemented, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The system introduces a standardized multicast discovery protocol as an intermediary mechanism between the diagnostic tool and VCI. This intermediary protocol handles the complexity of automatic detection, device identification, and IP assignment, allowing simple user operation while managing system complexity through well-defined communication protocols and automated handshake procedures
