Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If one-way communication is used from transmitter to vehicle, then device complexity is reduced and cost is lowered, but the ability to monitor and control vehicle parameters in real-time is limited
Solution Approach 1:
The communication system is segmented into distinct functional modules: a microprocessor unit for data processing, an analog input interface for receiving signals from the vehicle, an analog output interface for transmitting control signals, and a wired bidirectional bus interface for direct digital communication. This segmentation allows each module to perform its specific function independently, enabling real-time monitoring and control while keeping individual component complexity manageable.
Solution Approach 2:
The data link apparatus serves as an intermediary device between the user's computer and the vehicle's electronic components. It translates and converts signals between different interfaces (analog and digital), enabling communication without requiring the vehicle itself to have complex communication hardware. The microprocessor acts as a mediator that processes data and manages the bidirectional communication protocol.
2Loss of information
If bidirectional communication is implemented, then real-time monitoring and control of vehicle parameters is enabled, but device complexity increases
Solution Approach 1:
The data link apparatus is designed with multi-functionality to handle various communication tasks through a single integrated device. It can simultaneously perform data decoding from analog inputs, encoding for analog outputs, and bidirectional digital communication through the wired bus interface. This universal design enables comprehensive operational data feedback and control capabilities without requiring multiple separate devices, thereby managing complexity through consolidation rather than proliferation of components.
3Adaptability or versatility
If microprocessor-based decoding and encoding is used, then data communication flexibility is improved, but device complexity and processing requirements increase
Solution Approach 1:
The microprocessor dynamically changes data parameters including format, encoding scheme, and transmission protocol based on the specific communication requirements. It can switch between different data formats for operational data, control commands, and status information. This parameter adaptability allows the system to communicate with various electronic components using appropriate data formats while the microprocessor manages the complexity of format conversion and protocol selection through software control.
