Convertible Roof Controller Feedback for Operational Status
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of convertible vehicle roof opening/closing systems often experience erroneous recognition regarding the enablement or disablement of roof operations due to temporal factors such as temperature and vehicle speed, which are recoverable without repair.
Innovation Solution
A roof opening/closing system that includes a controller to determine the enablement or disablement of operations based on conditions like burning protection and notifies the user through a notifying device when the status changes, ensuring accurate user awareness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the opening/closing device prohibits operation based on temperature or vehicle speed conditions, then protection against damage is improved, but user understanding and accurate recognition of operational status deteriorate
Solution Approach 1:
The system implements feedback by notifying the user when the operational prohibition state is terminated. The notification device provides information about why the operation was prohibited and confirms when the system has recovered and is ready for operation, resolving the information asymmetry between system protection needs and user awareness
Solution Approach 2:
The system performs preliminary classification of abnormality items based on their significance before notifying the user. By pre-categorizing issues as either protection-related (temperature, speed) or breakdown-related, the system prepares information in advance to provide contextually appropriate notifications that help users understand the operational status
2Ease of repair
If abnormality items are classified and prioritized for notification, then repair workability is improved, but notification complexity increases
Solution Approach 1:
The notification system segments abnormality items into distinct categories: protection-related abnormalities (temperature, vehicle speed conditions) and breakdown-related abnormalities. This segmentation allows the system to apply different notification strategies for each category, simplifying the overall notification logic while maintaining comprehensive information delivery

AI summary
A roof opening/closing system of a convertible vehicle includes an opening/closing device for opening/closing the roof of the convertible vehicle; and a controller for determining, with respect to at least one of the opening and closing operations by the opening/closing device, whether to enable or disable the operation; and a notifying device for notifying a user whether the operation is enabled or disabled as determined by the controller. For example, in the case where the burning protection is turned off, following the determination based on the condition relevant to burning protection, lift of prohibition of the roof operation is notified when other permitting conditions for the roof operation are fulfilled.
