Vehicle Storage Compartment Door with Capacitive Sensor and Dynamic Actuation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicles often lack user-friendly mechanisms for opening and closing storage compartments, making it inconvenient for users to access stored items.
Innovation Solution
A storage compartment with a door that is operable between open and closed positions, equipped with a capacitive sensor integrated into a decorative trim component, allowing the door to pivot open via a pivot axis when a user touches the trim component, and an actuator that is electrically connected to the sensor only when the door is closed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional manual opening mechanism is used for the storage compartment door, then the device complexity is reduced, but the ease of operation deteriorates
Solution Approach 1:
The patent replaces the traditional mechanical manual opening mechanism with a capacitive sensor system that detects user touch and automatically activates an actuator to open the door. This substitution of mechanical systems with electronic sensing and actuation systems directly improves ease of operation while accepting increased device complexity, as the capacitive sensor and actuator work together to eliminate the need for manual mechanical manipulation.
2Reliability
If the sensor is always electrically connected to the actuator, then the reliability of the opening function is improved, but the manufacturing precision requirements worsen
Solution Approach 1:
The patent implements a dynamic electrical connection system where the sensor and actuator are electrically connected only when the door is in the closed position. When the door opens, the electrical connection is automatically disconnected. This dynamic approach allows for more tolerant manufacturing specifications since the electrical contacts only need to align precisely when the door is closed, rather than maintaining continuous precise alignment throughout all door positions, thus reducing manufacturing precision requirements while maintaining reliability during the critical closed state.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables convenient and aesthetically appealing access to storage compartments by allowing users to open the door with a touch, while simplifying manufacturing through electrical connectivity changes during door operation.
Implementation Method 1
A sensor is coupled to the door and configured to sense a user input. The sensor is a capacitive sensor; the capacitive sensor is configured to sense the user input when a user touches the decorative trim component
Data Source
AI summary
A storage compartment for the vehicle is disclosed herein. The storage compartment includes a receptacle. A door is coupled to the receptacle and is operable between an open position and a closed position. A sensors coupled to the door and is configured to sense a user input. An actuator is configured to allow the door to move from the closed position to the open position in response to the sensor, sensing the user input, wherein the actuator is electrically coupled to the sensor when the door is in the closed position and is electrically disconnected from the sensor, when the door is in the open position.
