Vehicle Engine Cover Unlocking via Gesture Sensors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing method for unlocking vehicle engine covers is overly complicated, requiring users to enter the passenger compartment and manually operate a handle.
Innovation Solution
A system that uses action sensors, such as gesture or contact sensors, to detect user actions and transmit signals to unlock the engine cover lock, allowing users to unlock the engine cover from outside the vehicle by matching preset unlock action signals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a manual opening handle is arranged in the passenger compartment, then the engine cover can be unlocked through cable action, but the user must first enter the passenger compartment to find and operate the handle, making the operation too complicated
Solution Approach 1:
The patent replaces the traditional mechanical cable-operated unlocking system with an electromagnetic locking mechanism. The engine cover lock uses an electromagnetic actuator that receives electrical signals from sensors (gesture sensors, contact sensors, or keyless entry systems) to automatically unlock the cover, eliminating the need for manual handle operation and cable mechanical transmission.
Solution Approach 2:
The system enables self-service unlocking by incorporating sensors that automatically detect user intent and trigger the unlocking mechanism without requiring manual intervention. For example, gesture sensors detect hand movements toward the engine compartment, contact sensors detect touching of the cover, or keyless entry systems detect authorized keys, automatically initiating the unlock sequence.
2Loss of time
If the unlocking operation requires entering the passenger compartment and manually pulling the handle, then the existing mechanism is simple, but the operation process becomes too complicated and time-consuming
Solution Approach 1:
The system performs preliminary detection of user intent before the actual unlocking is needed. Sensors continuously monitor for unlocking gestures, contact attempts, or key presence, and pre-activate the electromagnetic locking mechanism in preparation, reducing the actual unlocking time when the user needs access.
Solution Approach 2:
The electromagnetic unlocking system eliminates the time-consuming manual operations of entering the cabin, locating the handle, and pulling it. The electromagnetic actuator responds instantly to electrical signals, providing rapid unlocking compared to the sequential manual operations required by the mechanical cable system.

AI summary
The present invention discloses a method and system for unlocking vehicle engine cover. Method comprising: acquiring an action signal transmitted from an action sensor, and executing an action signal judging step; executing an unlocking step if the received action signal matches a preset unlock action signal, otherwise not executing the unlocking step, the unlock action signal is a combination of a signal or a plurality of consecutive signals; unlocking step: sending an unlock signal to an engine cover lock, wherein the unlock signal is used to control the engine cover lock to perform an unlock operation on a vehicle engine cover. The present invention detects an action signal from an action sensor, and controls whether or not to unlock the vehicle engine cover by matching the action signal with a preset unlock action signal. So users do not need to enter into the passenger compartment for unlocking. The operation is both convenient and rich sense of technology.
