Sequential Logic Charge Port Door Reminder System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle reminder systems fail to effectively notify drivers about open charge port doors after the vehicle is powered on or taken out of park, leading to potential inefficiencies and safety concerns.
Innovation Solution
A method utilizing sequential logic and vehicle sensors to produce notifications, where sensors detect the state of doors and charge/fuel connections, and a controller processes these signals to trigger alerts through various means such as audio, visual, or physical notifications, ensuring a specific sequence of events occurs before a reminder is produced.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a simple indicator system is used to notify drivers about open charge port doors, then the device complexity is reduced, but the reliability of the notification system deteriorates because it fails to account for sequential events such as fueling/charging operations
Solution Approach 1:
The system performs preliminary actions by detecting and recording the state of the charge port door and fueling/charging connection status before the vehicle is powered on or taken out of park. This allows the system to proactively determine whether a notification is necessary, ensuring reliable notification while maintaining simple system architecture through pre-condition checking
2Reliability
If sequential logic and multiple sensors are used to track door states and fueling/charging connections, then the reliability of notifications is improved, but the device complexity increases
Solution Approach 1:
The notification system is designed with multi-functionality to handle various scenarios: it can detect charge port door status, monitor fueling/charging connection states, determine vehicle power/park conditions, and selectively generate notifications based on the combination of these factors. This universal approach consolidates multiple detection functions into a single integrated system, improving reliability without proportionally increasing complexity
3Loss of information
If notifications are produced for all open door conditions, then the completeness of information is improved, but the loss of time increases due to unnecessary driver attention requirements
Solution Approach 1:
The notification system applies local quality by providing differentiated notification behavior based on the specific operational context. Instead of uniformly notifying for all open door conditions, the system selectively generates notifications only when the charge port door is open and no fueling/charging operation is active. This context-aware approach ensures complete and accurate information delivery while eliminating unnecessary notifications that would waste driver time
