Vehicle Door Control via Rain Sensor and Mobile Proximity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle door opening and closing systems require manual operation and lack automation for convenient boarding and exiting, especially in rainy conditions, which can lead to water ingress into the vehicle.
Innovation Solution
A vehicle door opening and closing control system that uses an antenna to wirelessly communicate with a mobile device to recognize the passenger's location and a rain sensor to detect weather conditions, controlling the door opening and closing device to automatically open or close the door based on the passenger's proximity and weather state.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual door operation is used, then device complexity is reduced, but ease of operation is worsened due to lack of automation convenience
Solution Approach 1:
The door opening and closing device operates automatically without requiring manual button manipulation. The controller autonomously controls the motor to open or close the door based on detected conditions (rainy weather state or mobile device location), making the system serve itself rather than requiring continuous user intervention.
Solution Approach 2:
The manual mechanical operation of door opening and closing is replaced with an automated electromechanical system. The motor-driven door opening and closing device substitutes manual mechanical action with automated electromagnetic actuation, controlled by electronic sensors and a controller.
2Ease of operation
If door is automatically opened in rainy weather, then ease of operation is improved, but water ingress risk increases
Solution Approach 1:
The controller detects the rainy weather state through the rain sensor before the door operation occurs. By identifying the harmful condition (rain) in advance, the system takes preliminary action to prevent water ingress by controlling the door to remain closed during rainy weather, thus counteracting the potential harmful effect before it can occur.
Solution Approach 2:
The rain sensor continuously monitors the weather state and provides feedback to the controller. The controller adjusts the door operation based on this feedback signal, creating a closed-loop control system that responds to environmental conditions and prevents water ingress when rain is detected.
3Ease of operation
If door remains open for extended period, then ease of operation is improved for passenger, but water ingress risk increases during rain
Solution Approach 1:
The rain sensor provides continuous feedback about weather conditions to the controller. If rain is detected while the door is open, the controller receives this feedback and automatically initiates door closing, creating a dynamic response system that adapts to changing environmental conditions and prevents water ingress.
Solution Approach 2:
The door operation is made dynamic rather than static. The controller can change the door state from open to closed based on real-time weather conditions detected by the rain sensor. This dynamic adjustment allows the system to maintain ease of operation when conditions are favorable while preventing water ingress when conditions deteriorate.
