Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing systems fail to prevent users from making contact with vehicle windows during remote operation when a person is inadvertently left inside the vehicle.

Innovation Solution

An information processing device and method that includes a controlling portion to transmit commands for window opening or closing, and to determine if a person is present inside the vehicle, stopping the operation if someone is detected.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If remote operation to open or close vehicle window is implemented, then convenience of operation is improved, but risk of contact injury to person inside vehicle increases

Engineering Contradiction:

Improveconvenience of remote window operationVSAvoidcontact injury risk to person inside vehicle

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The system performs preliminary detection of whether a person is present inside the vehicle before executing the remote window opening/closing operation. The control unit receives detection results from sensors (camera, ultrasonic sensor, infrared sensor, or microphone) and determines person presence before activating the window motor, thereby preventing contact injury before it can occur.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system establishes a feedback loop where detection results from sensors are continuously transmitted to the control unit during the window operation. The control unit monitors the detection results in real-time and can stop the window operation if a person is detected, creating a closed-loop control system that responds to changing conditions during the operation.

Inventive Principle:

Principle #23Feedback

2Reliability

If multiple detection methods are implemented to detect person presence, then detection reliability is improved, but device complexity increases

Engineering Contradiction:

Improveperson presence detection reliabilityVSAvoiddetection system complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The system employs multiple types of sensors (camera, ultrasonic sensor, infrared sensor, microphone) that can serve multiple functions. These sensors can detect person presence for window operation safety, and can also be used for other vehicle functions such as monitoring, security, or environmental control, making the detection system multi-functional and reducing overall system complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system utilizes existing vehicle sensors and components for person presence detection rather than adding dedicated new hardware. The control unit leverages the vehicle's existing sensor network and communication infrastructure (V2X communication) to perform detection, allowing the system to serve itself using available resources and reducing additional complexity.

Inventive Principle:

Principle #25Self-service

AI summary

An information processing device includes a controlling portion configured to execute the followings: when a predetermined condition for opening or closing of a window of a vehicle is established, transmitting, to the vehicle, a command to start the opening or closing of the window; acquiring information to determine whether or not a person is present inside the vehicle during the opening or closing of the window; and in a case where it is determined that a person is present inside the vehicle, transmitting, to the vehicle, a command to stop the opening or closing of the window.
