Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If new technologies with higher processing power requirements are integrated into conventional vehicles, then the vehicle's functional capabilities are improved, but the compatibility with existing semiconductor processing devices deteriorates
Solution Approach 1:
The control device is divided into a base block containing existing semiconductor processing devices and an upgrade block containing new processing components. This segmentation allows the vehicle to maintain compatibility with existing devices while integrating new technologies with higher processing power requirements, resolving the contradiction between functional capabilities and compatibility.
Solution Approach 2:
The upgrade block is detachably mounted on the base block, forming a nested structure where the new processing components are integrated within the existing control device framework. This nesting approach enables the vehicle to incorporate advanced technologies while maintaining the structural and electrical compatibility of the original system.
2Reliability
If the vehicle uses older semiconductor processing devices, then compatibility is maintained, but processing power is insufficient for new technologies
Solution Approach 1:
By segmenting the control device into base and upgrade blocks, the system allows the upgrade block to provide enhanced processing power while the base block maintains compatibility through existing semiconductor devices. The auxiliary processor in the base block coordinates with the main processor in the upgrade block to achieve both compatibility and increased processing power.
Solution Approach 2:
The system merges the existing semiconductor processing devices in the base block with the new high-performance processing components in the upgrade block. This combination allows the vehicle to maintain compatibility while achieving the necessary processing power for autonomous driving and infotainment systems.
3Ease of manufacture
If a modular control device with detachable upgrade block is implemented, then ease of upgrading is improved, but device complexity increases
Solution Approach 1:
The control device is segmented into modular base and upgrade blocks with standardized interfaces, enabling easy upgrading by simply detaching and attaching different upgrade blocks. This segmentation reduces the complexity of upgrading processes while managing the inherent structural complexity through standardized connection mechanisms.
Solution Approach 2:
The base block is designed with universal interfaces and an auxiliary processor that can work with multiple types of upgrade blocks. This universality simplifies the upgrading process by providing a standardized platform that reduces the complexity of integrating different upgrade components.
4Reliability
If validation checking is performed through both physical detection and periodic messages, then reliability of upgrade block validation is improved, but processing time increases
Solution Approach 1:
The checking circuit performs physical detection of the upgrade block's validity in advance before the upgrade block is activated. This preliminary validation ensures that only authenticated upgrade blocks are installed, improving validation reliability while minimizing processing time during actual operation since the authentication is completed beforehand.
Solution Approach 2:
The main processor periodically transmits checking messages to verify the upgrade block's continued validity during operation. This periodic validation maintains high reliability by detecting potential issues early while minimizing processing time impact by using efficient message-based verification rather than continuous checking.
