Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The inefficiency in utilizing communication capacity in motor vehicle networks due to high metadata-to-useful data ratios when using Internet Protocol (IP) technology, leading to suboptimal bandwidth utilization compared to other automotive communication protocols.
Innovation Solution
Implementing a hierarchical network structure with information nodes that combine and filter data packets, ensuring only required information is transmitted to specific nodes, thereby optimizing the metadata-to-useful data ratio and reducing bandwidth usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If Internet Protocol (IP) technology is used for transmitting brief pieces of information in motor vehicle networks, then the flexibility and versatility of communication is improved, but the metadata-to-useful data ratio increases unfavorably, reducing communication efficiency
Solution Approach 1:
The network is segmented into multiple hierarchical levels (Level 1, Level 2, Level 3) with information nodes at each level. This segmentation allows data to be processed and filtered at appropriate levels, reducing the metadata overhead that would otherwise be present in every transmission across the entire network.
Solution Approach 2:
The patent extracts and removes unnecessary metadata from data packets by implementing information nodes that filter and process data at hierarchical levels. Only relevant information is extracted and forwarded to the next level, eliminating redundant metadata that would increase the metadata-to-useful data ratio.
2Loss of information
If individual pieces of information are transmitted separately using IP protocol, then the information can be delivered to specific nodes, but the proportion of metadata within each data packet becomes large, leading to unfavorable bandwidth utilization
Solution Approach 1:
Multiple individual pieces of information are merged into aggregated data packets at higher hierarchical levels. This combining reduces the total number of separate transmissions and their associated metadata overhead, improving bandwidth utilization while maintaining accurate information delivery to target nodes.
Solution Approach 2:
Information nodes at intermediate hierarchical levels act as mediators that receive, process, and forward data packets. These intermediaries filter and aggregate information, reducing metadata overhead before forwarding to the next level, thus improving bandwidth utilization while ensuring accurate delivery.
3Productivity
If a hierarchical network structure with information nodes is implemented, then the metadata-to-useful data ratio is optimized and bandwidth utilization is improved, but the device complexity and network structure become more complex
Solution Approach 1:
Each information node is designed with specific local functions appropriate to its hierarchical level. Level 1 nodes perform basic filtering, Level 2 nodes perform aggregation, and Level 3 nodes perform final delivery. This local specialization reduces overall complexity by distributing functions rather than requiring every node to handle all processing tasks.
Solution Approach 2:
The hierarchical network structure allows for dynamic configuration and scaling. Information nodes can be added or removed at different levels without requiring complete reconfiguration of the entire network, making the complexity manageable and adaptable to different network sizes and requirements.
