Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fixed restriction information is applied to unmanned driving operations, then safety is improved, but workability deteriorates due to excessive restrictions
Solution Approach 1:
The restriction information is made dynamic by automatically updating it based on the vehicle's manufacturing process stage. The control device changes speed limits, turning angle limits, and other operational restrictions according to the current process, allowing safe operation in early stages while enabling greater freedom as the vehicle approaches completion.
Solution Approach 2:
The system changes operational parameters (speed limits, turning angles, operational restrictions) based on the manufacturing process stage. By dynamically adjusting these parameters according to process information, the system maintains safety while improving workability at different stages of vehicle production.
2Reliability
If uniform operation restrictions are applied across all manufacturing processes, then safety is maintained, but productivity deteriorates due to unnecessary constraints
Solution Approach 1:
The manufacturing process is segmented into multiple stages, and restriction information is customized for each stage. Instead of applying uniform restrictions across all processes, the system divides the manufacturing workflow and applies appropriate restrictions only where needed, improving overall productivity while maintaining safety.
Solution Approach 2:
The restriction information dynamically adapts to the current manufacturing process stage. As the vehicle progresses through different manufacturing stages, the system automatically updates operational restrictions, allowing maximum productivity in stages where safety risks are lower while maintaining necessary constraints in high-risk stages.
3Reliability
If strict operational restrictions are applied during unmanned driving, then safety is improved, but device complexity increases due to multiple update mechanisms
Solution Approach 1:
The system uses feedback from process information to automatically update restriction information. The control device receives process information, determines the current manufacturing stage, and automatically adjusts operational restrictions accordingly. This feedback mechanism maintains safety while avoiding the need for complex manual update procedures.
Solution Approach 2:
The control device automatically updates its own restriction information based on received process information, without requiring external manual intervention. The system serves itself by autonomously adjusting operational parameters according to the manufacturing stage, reducing the complexity associated with manual system configuration and updates.
