Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple electronic devices following different standards are integrated in a vehicle, then the functionality and capabilities of the vehicle system are enhanced, but the design complexity increases significantly
Solution Approach 1:
The patent introduces a signal integration system that acts as an intermediary between electronic devices following different standards. This integration system includes a controller that receives signals from various devices (such as audio systems, navigation systems, and communication devices) and processes them according to a unified protocol, thereby enabling seamless integration without requiring complex point-to-point connections between each device pair.
Solution Approach 2:
The signal integration system is designed with universal functionality to handle multiple types of signals and communication protocols simultaneously. The controller can process audio signals, video signals, data signals, and control signals from different sources and convert them into a standardized format that can be distributed to various output devices, making the system adaptable to diverse electronic devices without requiring device-specific integration circuits.
2Adaptability or versatility
If different communication standards are used by various electronic devices, then device compatibility and choice are improved, but system integration difficulty increases
Solution Approach 1:
The signal integration system serves as a mediator that translates between different communication standards. The controller includes protocol conversion modules that can receive signals in various formats (such as CAN bus, LIN bus, Ethernet, or proprietary protocols) and convert them into a unified internal format, eliminating the need for manufacturers to create complex direct integrations between devices with incompatible standards.
Solution Approach 2:
The integration system is segmented into modular functional blocks, each capable of handling specific communication protocols or signal types. This modular architecture allows the system to independently process different standards through dedicated conversion modules, simplifying the integration process by breaking down the complex task of multi-standard compatibility into manageable, independent segments that can be configured flexibly.
