Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicular visual recognition devices require manual operation to switch between using an optically reflected image and a displayed image for checking vehicle surroundings, which is burdensome, especially when factors like open doors or seated occupants affect the usability of these systems.
Innovation Solution
A vehicular visual recognition device comprising an imaging section, a display section, and a controller that automatically switches between displaying captured images on a monitor and using an optical mirror for rearward checking based on predetermined signals, such as door opening/closing or occupant presence, to adapt to the vehicle's situation without manual intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual operation is required to switch between optical mirror and display section, then the switching control is simple, but the ease of operation deteriorates due to burdensome manual intervention
Solution Approach 1:
The system performs automatic switching between the optical mirror and display section based on detected vehicle conditions (door opening/closing, occupant presence) without requiring manual operation. The controller autonomously determines the appropriate display mode and activates the corresponding section, making the system serve itself by eliminating the need for user intervention in the switching process.
Solution Approach 2:
The system incorporates sensors that detect vehicle conditions (door status, occupant presence) and provide feedback to the controller. Based on this feedback, the controller automatically adjusts the switching between optical mirror and display section, creating a closed-loop control system that responds to changing vehicle conditions without manual input.
2Reliability
If the display section is always active, then the captured image is always visible, but the loss of time increases due to unnecessary power consumption and reduced visibility of optical reflections
Solution Approach 1:
The display section and optical mirror are switched between active and inactive states based on detected vehicle conditions. The system periodically evaluates sensor inputs (door status, occupant presence) and activates only the necessary display mode, avoiding continuous operation of both sections and thereby reducing unnecessary power consumption and visibility interference.
Solution Approach 2:
The system dynamically adjusts the state of the display section and optical mirror based on real-time vehicle conditions. Rather than maintaining a fixed state, the controller continuously monitors sensor data and switches between display modes to optimize both reliability and efficiency, activating the display only when conditions warrant its use.
3Use of energy by moving object
If the display section switches to non-display state when back door is open, then power is saved, but the loss of information occurs when rearward checking is needed
Solution Approach 1:
The controller continuously monitors door opening/closing status through sensors and uses this feedback to determine when to activate or deactivate the display section. When the back door is opened, the system receives feedback about this condition and automatically switches to the appropriate display mode, ensuring rearward checking information is available when needed while saving power when the door is closed and checking is less critical.
Solution Approach 2:
The system autonomously manages the display section state based on detected door conditions, eliminating the need for manual switching. When the back door is opened, the controller automatically activates the display to provide rearward checking information, and when closed, it deactivates the display to save power, making the system self-regulating based on vehicle conditions.
4Reliability
If the display section is always on, then rearward checking is always available, but the device complexity increases due to continuous power supply requirements
Solution Approach 1:
The controller autonomously manages the power supply to the display section based on detected vehicle conditions, eliminating the need for manual power management. The system self-determines when the display should be active (when rearward checking is needed) and automatically controls power supply accordingly, reducing complexity compared to systems requiring continuous power or manual switching mechanisms.
Solution Approach 2:
The power supply to the display section is dynamically controlled based on real-time vehicle conditions detected by sensors. The controller adjusts the display state (on/off) according to door status and occupant presence, creating a dynamic power management system that maintains reliability when needed while reducing complexity by eliminating continuous power requirements.
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 seamless and automatic switching between using the displayed image and the optically reflected image to suit the vehicle's situation, preventing loss of rearward checking capability due to open doors or obstructive occupants, thereby enhancing user convenience and safety.
Implementation Method 1
The optical mirror is provided at a display face side of the display section, transmits the captured image being displayed when the display section is in a display state, and reflects light from rearward of the vehicle when the display section is in a non-display state
