Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional radio communication systems are used for vehicle-to-vehicle communication, then basic data exchange is possible, but data transmission quality and communication reliability are insufficient
Solution Approach 1:
The system dynamically switches between different antenna modules (first antenna module for WLAN, second antenna module for Bluetooth) based on communication requirements and environmental conditions. This dynamic adaptation allows the system to optimize signal quality and reliability for different transmission scenarios, resolving the contradiction between basic functionality and transmission quality.
Solution Approach 2:
The system changes operational parameters by selecting different frequency bands (2.4 GHz for Bluetooth, 5.9 GHz for WLAN) and different communication protocols based on the specific communication needs. This parameter adaptation enables the system to achieve high-quality data transmission while maintaining compatibility with various communication standards.
2Adaptability or versatility
If multiple antenna modules are used for different communication protocols, then communication versatility is improved, but device complexity increases
Solution Approach 1:
The central processing unit is designed to universally control multiple antenna modules through a unified architecture. The CPU can execute different communication protocols (WLAN, Bluetooth) and manage multiple antenna modules (first antenna module, second antenna module) through a single control interface, achieving multi-functionality without proportionally increasing system complexity.
Solution Approach 2:
The central processing unit acts as an intermediary that manages the complexity of multiple antenna modules and communication protocols. It provides a unified control layer that simplifies the interface between the diverse antenna modules and the higher-level application logic, making the system easier to manage despite its versatility.
3Adaptability or versatility
If software-assisted signal processing is implemented, then signal processing flexibility is improved, but processing core workload increases
Solution Approach 1:
The system uses periodic signal processing operations where the processing core performs software-assisted signal processing only when needed for specific communication tasks. The processing core alternates between active signal processing modes and idle states, managing workload by executing processing operations periodically rather than continuously, thus maintaining flexibility while controlling computational burden.
