Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems in electric vehicles face challenges in managing high communication loads and inefficient use of system resources due to the generation of multiple diagnostic trouble codes, leading to increased traffic and resource waste.
Innovation Solution
A communication system and method that utilizes a first communication packet structure to include multiple request information and a second communication packet structure to include distinct answer and diagnosis information, using delimiter information to distinguish between multiple request and answer/diagnosis pairs, thereby optimizing communication efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple carriers are used to support different protocol types, then protocol compatibility is improved, but network complexity and cost increase
Solution Approach 1:
The patent implements a single carrier that can dynamically support multiple protocol types (ITS-G5, Wi-Fi, Bluetooth, etc.) through configurable protocol stacks and flexible resource allocation mechanisms, eliminating the need for separate dedicated carriers for each protocol while maintaining full protocol compatibility
Solution Approach 2:
The patent combines multiple protocol support capabilities into a unified carrier framework where different protocol stacks coexist and share common infrastructure resources such as synchronization mechanisms, physical layer processing, and network management functions, thereby reducing overall system complexity
2Reliability
If dedicated carriers are allocated for each protocol type, then protocol performance is improved, but spectrum efficiency deteriorates
Solution Approach 1:
The patent implements dynamic protocol stack configuration that allows the system to adaptively allocate resources and switch between different protocol modes based on real-time traffic demands and service requirements, enabling a single carrier to efficiently support multiple protocols with varying performance characteristics
Solution Approach 2:
The patent changes the operational parameters of the carrier by implementing configurable protocol stacks that can be dynamically activated or deactivated, allowing the same physical carrier to operate under different protocol regimes optimized for specific service types without requiring dedicated spectrum allocation for each protocol
3Reliability
If protocol stacks are designed for specific carrier types, then protocol performance is improved, but device adaptability deteriorates
Solution Approach 1:
The patent designs a universal protocol stack architecture that can operate effectively across different carrier types (licensed, unlicensed, shared spectrum) by implementing abstracted interface layers and configurable protocol parameters that adapt to the specific characteristics of each carrier while maintaining consistent performance
Solution Approach 2:
The patent segments the protocol stack into modular functional layers with well-defined interfaces, allowing each layer to be independently configured and optimized for specific carrier types while maintaining overall protocol performance through standardized interaction patterns between layers
