Vehicle Forced Ventilation via Mobile Device Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing forced-ventilation devices for vehicles require manual operation via a remote-control transmitter, which can compromise security as the window is rolled down when the user is not present, and necessitates frequent operation.
Innovation Solution
A forced-ventilation device utilizing a smart entry system with a mobile device and control portion that automatically initiates ventilation by detecting the mobile device's presence within a predetermined area, allowing the vehicle's blower to operate and windows to open without user intervention, ensuring security and convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the forced-ventilation device is operated by remote-control transmitter, then the user can ventilate the compartment before entering the vehicle, but the window is rolled down even when the user is not around the vehicle which endangers security
Solution Approach 1:
The control portion continuously monitors the detection area for the mobile device's presence and only activates ventilation when the device is detected within the predetermined area, providing real-time feedback control that prevents unauthorized operation while maintaining ease of use for authorized users
Solution Approach 2:
The mobile device acts as an intermediary between the user and the ventilation system, serving as a portable authentication key that must be present in the detection area to trigger ventilation, thereby eliminating the need for remote control transmitters while maintaining security
2Reliability
If the forced-ventilation device requires manual operation via remote-control transmitter, then security can be maintained, but the user is required to operate the device each time which reduces convenience
Solution Approach 1:
The ventilation system automatically detects when the mobile device enters the detection area and initiates ventilation without requiring manual operation, making the system serve itself by monitoring its own operational conditions and activating when appropriate
Solution Approach 2:
The mobile device is prepared in advance as a portable authentication key, and the system is pre-configured with the detection area parameters, so that when the device enters the area, ventilation can immediately begin without requiring any additional user action or remote control operation
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
The solution enables automatic and secure ventilation of the vehicle compartment without manual operation, ensuring effective cooling and enhanced user safety as the process is visible and controllable by the user.
Implementation Method 1
The control portion is mounted on the vehicle and locks or unlocks a door of the vehicle by transmitting a call signal to the mobile device through radio wave and by verifying a response signal which is transmitted from the mobile device through radio wave in response to the call signal
Implementation Method 2
a blower of an air-conditioning device of the vehicle... commands the air-conditioning device to operate the blower

AI summary
A forced-ventilation device ventilates a compartment of a vehicle by forced ventilation by actuating a blower of an air-conditioning device of the vehicle when the compartment is left at a high temperature. When a mode for forced ventilation has been set by the user, when a mobile device approaching the vehicle together with a user enters a predetermined detection area within which the mobile device is detectable by a response signal, and when the response signal is successfully verified, a control portion switches ON an ignition switch of the vehicle, opens one or two or more windows using an opening and closing mechanism, and directs the air-conditioning device to actuate the blower.
