Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple driving assistance processes are provided for different traveling situations, then the adaptability and safety of the system is improved, but the device complexity and difficulty of selection increases
Solution Approach 1:
The system pre-establishes association data linking multiple traveling situations with corresponding situation assistance processes before operation. When a traveling situation is detected, the system automatically proposes the pre-associated assistance process, eliminating the need for drivers to manually select from multiple options and reducing selection complexity while maintaining adaptability.
Solution Approach 2:
The system introduces an intermediary mechanism (the association data and proposal system) between the traveling situation detection and the assistance process execution. This intermediary automatically matches situations with appropriate processes, shielding drivers from the complexity of multiple available options while ensuring the right assistance is provided.
2Reliability
If automated switching to driving assistance is implemented when driver wakefulness decreases, then the safety is improved, but the ease of operation decreases due to automatic control
Solution Approach 1:
Instead of requiring drivers to manually select assistance processes (traditional approach), the system inverts the control flow by automatically proposing appropriate processes based on detected traveling situations and driver state. This maintains driver awareness and approval authority while reducing operational burden, balancing safety and ease of operation.
Solution Approach 2:
The system implements a feedback loop where driver approval is required for proposed assistance processes. The human interface device presents proposals to the driver, who can approve or reject them. This feedback mechanism ensures drivers maintain control over assistance selection while benefiting from automated situation analysis and process recommendation.
