Remote Control Sequence for Automotive Maneuver Safety
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing remote control systems for motor vehicles can unintentionally trigger automatic maneuvers due to accidental pressure on control buttons, lacking user verification and safety monitoring.
Innovation Solution
A method using a predetermined sequence of actuating multiple control members on a remote control device, including a prolonged press followed by a timely press of another button, with warning signals and failure detection to ensure intentional triggering and safe operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a single push button is used to trigger automatic operations, then the ease of operation is improved, but the reliability deteriorates due to accidental triggering
Solution Approach 1:
The single button trigger is segmented into a multi-step sequence: first activating a first control element, then within a predetermined delay period, activating a second control element. This segmentation transforms a single accidental-trigger-prone action into a deliberate multi-step process that is much harder to trigger accidentally while remaining easy to execute intentionally.
Solution Approach 2:
The system requires a preliminary action (activating the first control element and holding it for a predetermined period) before the actual trigger (second control element) can be activated. This preliminary action serves as a verification step that confirms intentional user intent, preventing accidental triggering while maintaining operational simplicity.
2Ease of operation
If the automatic operation executes as long as the button is held down, then the ease of operation is improved with real-time control, but the reliability deteriorates when the user is unaware of the operation progress
Solution Approach 1:
The system incorporates feedback mechanisms including warning signals generated when the first predetermined duration has elapsed, and failure detection when the first control element is actuated for too long. This feedback loop keeps the user informed about the operation status and potential accidental triggering, enhancing safety while maintaining the continuous execution capability during button holding.
Solution Approach 2:
The system implements preliminary anti-action through the multi-step activation sequence and monitoring mechanisms that prevent harmful accidental operations before they can occur. The predetermined delay and sequential button activation create a barrier against unintentional triggering, while the warning signals provide early warning of potential safety issues.
