Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If factory window tint with fixed VLT is used, then privacy and interior cooling are provided, but dynamic control over light transmission is not available
Solution Approach 1:
The patent applies smart glass technology that enables the window to dynamically change its visual light transmission properties from a fixed state to a variable state. The smart glass can transition between different tint levels (e.g., from clear to dark) in response to control signals, allowing the window to adapt to different lighting conditions, privacy requirements, and energy efficiency needs throughout the day.
Solution Approach 2:
The system incorporates video cameras and image analysis algorithms that continuously monitor the vehicle's environment and automatically trigger tinting adjustments based on detected events such as approaching vehicles, occupancy status, or lighting conditions. This closed-loop feedback mechanism enables autonomous adaptation without requiring manual user input, resolving the contradiction between adaptability and complexity by automating the control process.
2Ease of operation
If smart glass with dynamic adjustment is implemented, then user comfort and energy efficiency are enhanced, but system complexity increases
Solution Approach 1:
The system employs image analysis algorithms that automatically process video stream data from external cameras to detect relevant events (such as approaching vehicles, pedestrians, or lighting changes) and autonomously trigger the appropriate tinting adjustments. This self-service capability eliminates the need for manual user intervention, enhancing comfort while managing system complexity through automation rather than requiring complex user interfaces or manual controls.
3Productivity
If automated event-based control is implemented, then productivity and energy efficiency are improved, but device complexity increases
Solution Approach 1:
The system proactively adjusts the window tinting in anticipation of events that will affect interior comfort or energy efficiency. For example, when the image analysis detects an approaching vehicle or changing lighting conditions, the system pre-adjusts the tint level before the actual condition occurs, maximizing energy efficiency and comfort while maintaining relatively simple control logic based on predefined event triggers.

AI summary
Automated control of visual light transmission through one or more vehicle windows is provided, which includes providing a control system for controlling visual light transmission through the window, where the window includes smart glass, with visual light transmission through the window being dynamically adjustable by the control system. The control system receives a video stream from at least one video camera associated with the vehicle, and analyzes the video stream for a specified event. Based on detecting the event, the control system triggers an action to adjust the visual light transmission through the window.
