Proactive Vehicle Door Hazard Detection and Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicle door accidents occur due to lack of mechanisms to detect oncoming traffic and external objects, leading to potential collisions and damages, with no proactive systems to prevent such incidents.
Innovation Solution
Integration of sensors and an artificial intelligence module in vehicle doors to detect potential hazards, automatically stop the door from opening, and alert users and external objects, combined with an external alert mechanism to prevent accidents.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If vehicle doors are equipped with sensors and AI modules to detect hazards and automatically stop opening, then accident prevention capability is improved, but device complexity and cost increase
Solution Approach 1:
The system performs preliminary detection of hazards before the door opening action is completed. Sensors continuously monitor the environment around the vehicle door, and the AI module predicts potential collision risks in advance, allowing the system to prevent accidents before they occur rather than reacting after contact is made.
Solution Approach 2:
The system implements a feedback loop where sensors continuously provide real-time data about the environment to the AI module, which then adjusts door opening commands based on detected hazards. The system monitors the door's movement and external conditions, providing continuous feedback to maintain safe operation and prevent collisions.
2Reliability
If external alert mechanisms such as lights and notifications are added to warn oncoming traffic and objects, then safety awareness is improved, but device complexity and energy consumption increase
Solution Approach 1:
External alert mechanisms operate periodically rather than continuously. The system activates lights and notifications only when sensors detect potential hazards or when the door is in the process of opening, rather than remaining constantly active. This periodic operation reduces energy consumption while maintaining effective safety warnings when needed.
Solution Approach 2:
The external alert mechanisms provide preliminary warning to oncoming traffic and objects before the door actually opens or before a collision would occur. By activating alerts in advance when hazards are detected, the system prevents accidents by giving external objects time to react, rather than waiting until the last moment.
3Reliability
If the door stopping mechanism activates at a predetermined distance from detected objects, then collision prevention is improved, but the door opening range is restricted
Solution Approach 1:
The door stopping distance is not fixed but dynamically adjusted based on real-time conditions. The AI module continuously evaluates the detected hazard's type, speed, and trajectory, then adjusts the stopping point accordingly. This allows the door to open closer to objects when the situation permits while maintaining safety margins when risks are higher.
Solution Approach 2:
The system changes the stopping parameter (distance from detected object) based on multiple variables including object type, relative velocity, and environmental conditions. Rather than using a single predetermined distance, the AI module adjusts this parameter dynamically to optimize both safety and door opening range for each specific situation.

AI summary
This solution will help to detect oncoming traffic and/or nearby external objects when the vehicle door is being opened, and it would automatically stop the vehicle door from opening further if there is a possibility of an accident involving the vehicle doors or its users. This solution will notify vehicle users using an indicator on the vehicle door and/or an existing notification systems in vehicle that vehicle door has been restricted from opening further due to potential of an accident. This invention also has an external alert mechanism, which would generate alert externally that vehicle door is about to be opened, and therefore, help to prevent accidents. This invention will also comprise of an artificial intelligence module within the proactive vehicle door system, where such module would constantly gather data, analyze and provide proactive suggestions or even take necessary actions in order to help prevent any vehicle door related accidents.
