Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If option functions are loaded in the vehicle beforehand to enable execution according to user requests, then the versatility and adaptability of the vehicle is improved, but the risk of undetected device failures and safety issues increases
Solution Approach 1:
The system performs preliminary failure detection by collecting failure information from electronic controllers and instruments before the user requests option function execution. The determination unit assesses execution readiness in advance, ensuring that only functions with no detected failures are made available for execution, thus preventing unsafe operations while maintaining versatility
Solution Approach 2:
The system establishes a feedback loop where failure information is continuously collected from vehicle components, processed by the determination unit to assess execution readiness, and used to dynamically control the availability of option functions. This feedback mechanism ensures that the system adapts to the actual operational status of vehicle components, maintaining reliability while preserving adaptability
2Reliability
If failure information is collected and execution readiness is determined for each option function, then the safety and reliability of option function execution is improved, but the system complexity and processing time increase
Solution Approach 1:
The system employs a universal function management approach where a single determination unit assesses execution readiness for multiple option functions based on failure information from various electronic controllers and instruments. This centralized multi-functional assessment mechanism reduces overall system complexity compared to having separate assessment systems for each option function while maintaining comprehensive reliability checking
Solution Approach 2:
The electronic controllers and instruments perform self-diagnosis to generate failure information, which is then collected by the information collection unit. This self-service approach allows components to autonomously provide diagnostic data, reducing the complexity of external monitoring systems while ensuring comprehensive failure detection for reliable option function execution assessment
3Reliability
If the system notifies users of unavailable options and prevents installation of software for failed functions, then the safety is improved, but the user convenience and speed of function activation may be reduced
Solution Approach 1:
The system takes preliminary anti-action by preventing the installation or execution of option functions associated with failed components before the user can be affected. The determination unit blocks software installation for functions with detected failures, and the notification unit informs users of unavailable options in advance, thus preventing potential safety issues while maintaining user convenience through clear communication
Solution Approach 2:
The notification unit serves as an intermediary between the determination unit and the user, translating complex failure assessment results into clear notifications about option function availability. This intermediary mechanism maintains user convenience by providing straightforward information about which functions are available, while ensuring safety by preventing access to functions with detected failures

AI summary
A function management system includes: an information collection unit configured to collect failure information including information about a failure of an electronic controller loaded in the vehicle and/or information about a failure of an instrument controlled by the electronic controller; and a determination unit configured to determine whether or not execution preparation for utilization start is possible for each of the option functions, and the determination unit determines that the execution preparation of the option function is impossible when a failure has been found in the electronic controller or the instrument required for execution of the option function, for each of the option functions, based on the failure information.
