Vehicle Door Gripper Interface With Dual Finger Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle door operation devices face challenges in configuration as a single independent unit due to the need for a door sensor on the hinge portion, increasing assembly complexity.
Innovation Solution
An operation device with a gripper or handle equipped with multiple sensors on different surfaces of the door, allowing accurate detection of occupant input and preventing unintended operation, enabling easy installation and accurate detection of intentional finger contact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the door sensor is provided on the hinge portion of the door, then the door open/closed state can be detected, but the device cannot be configured as a single independent unit and assembly work processes increase
Solution Approach 1:
The door sensor function is extracted from the hinge portion and integrated into the operation device itself. The operation device includes a sensor that detects the door open/closed state, eliminating the need for a separate door sensor on the hinge. This allows the operation device to be configured as a single independent unit that can be easily assembled to the door.
Solution Approach 2:
The door sensor function is merged with the operation device components. The operation device integrates multiple functions including finger detection sensors, operation interface, and door state detection into a single unified unit, simplifying the overall system structure and reducing assembly complexity.
2Measurement precision
If a single sensor is used to detect finger position, then the device structure is simple, but the accuracy of determining intentional input is insufficient
Solution Approach 1:
Multiple sensors are positioned at different locations on the gripper (first sensor on outer side surface, second sensor on inner side surface or upper surface). Each sensor detects finger contact from different perspectives, and the controller analyzes the combination of detection results to accurately determine intentional input. This local distribution of sensing functions enhances detection accuracy without requiring a single complex sensor.

AI summary
The present invention relates to an operation device which can be easily installed on a vehicle door, and a vehicle door comprising the operation device. An operation device of the present invention comprises: a gripper provided on an inner surface of a door of a vehicle; an operation interface provided on an inner side surface of the gripper for receiving an operation input entered by an occupant to operate at least one in-vehicle device; a first sensor provided on an outer side surface of the gripper for detecting a finger of the occupant; a second sensor provided on at least one of the inner side surface and an upper surface of the gripper for detecting a finger of the occupant; and a controller connected to the operation interface, the first sensor, the second sensor, and the at least one in-vehicle device. The controller controls the at least one in-vehicle device based on a signal from the operation interface when both the first sensor and the second sensor detect the occupant, and prohibits the at least one in-vehicle device from being controlled based on a signal from the operation interface when at least one of the first sensor and the second sensor does not detect the occupant.
