Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If data is transmitted to high-performance storage device through single in-vehicle network path, then network configuration is simple, but network bottleneck occurs during data read/write operations
Solution Approach 1:
The patent segments the data transmission path by creating multiple network paths (first path and second path) from the signal processing device to the storage device. This segmentation allows data to be distributed across multiple channels, preventing any single path from becoming a bottleneck while maintaining manageable network configuration through centralized control.
Solution Approach 2:
The patent transitions from a single-dimensional transmission path to a multi-dimensional network topology by establishing parallel first and second paths. This dimensional expansion enables simultaneous data flow through multiple routes, increasing overall throughput without significantly complicating the network architecture through standardized path management.
2Reliability
If multiple network paths are established for data transmission, then data transmission stability improves, but network controller complexity increases
Solution Approach 1:
The network controller is designed with multi-functionality to handle both first and second transmission paths using unified control logic. It can dynamically allocate bandwidth, manage packet routing, and monitor network status across multiple paths through a single centralized unit, avoiding the need for separate controllers for each path and thus limiting complexity increase.
Solution Approach 2:
The network controller implements dynamic bandwidth allocation and adaptive path selection that adjusts transmission parameters based on real-time network conditions. This dynamic capability allows the system to maintain stable data transmission across multiple paths while using intelligent algorithms to manage complexity rather than relying on static, overly complex hardware configurations.
3Productivity
If bandwidth is allocated dynamically based on network conditions, then data transmission efficiency improves, but control algorithm complexity increases
Solution Approach 1:
The network controller implements feedback mechanisms that continuously monitor network status, data flow rates, and path conditions. Based on this feedback, the controller dynamically adjusts bandwidth allocation for the first and second paths to optimize transmission efficiency. The feedback loop uses standardized algorithms to process network metrics and make allocation decisions, keeping control complexity manageable while achieving high efficiency.
Solution Approach 2:
The system dynamically changes transmission parameters such as bandwidth allocation ratios, packet sizes, and transmission rates based on network conditions. These parameter adjustments are made through controlled algorithms that modify operational variables rather than restructuring the entire control system, thereby improving efficiency without proportionally increasing complexity.
