Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional image-generating systems and electrochromic dimming technologies struggle with dynamic control of image positioning and dimming on transparent substrates, particularly in vehicles, where sun glare and headlight glare require adaptive solutions to maintain visibility and safety.
Innovation Solution
A dynamic positioning control system (DPCS) that integrates an image processor and dimming controller with light sensors and electrodes, allowing for independent movement and sizing of images and dimming areas on transparent substrates, such as windshields, to dynamically adjust based on light conditions and user input, ensuring optimal visibility and privacy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional image-generating systems are used on transparent substrates, then images can be displayed, but dynamic control of image positioning and sizing is limited
Solution Approach 1:
The patent implements dynamic control of image-generating elements by enabling independent movement and resizing of multiple images on the transparent substrate through a control system that responds to user input and sensor data, transforming static display capabilities into adaptive, reconfigurable imaging
2Adaptability or versatility
If electrochromic dimming is applied to the entire substrate, then visibility control is achieved, but selective positioning of dimming areas is lost
Solution Approach 1:
The patent divides the electrochromic dimming capability into multiple independently controllable areas on the transparent substrate, allowing selective positioning and independent control of dimming zones through separate electrode connections and control logic
Solution Approach 2:
The patent enables different regions of the transparent substrate to have different dimming states simultaneously, allowing specific areas to be dimmed while other areas remain transparent, providing localized control over light transmission properties
3Adaptability or versatility
If static image positions are used on the substrate, then system simplicity is maintained, but adaptability to light conditions and user needs is reduced
Solution Approach 1:
The patent incorporates sensors that detect light conditions and provide feedback to the control system, which automatically adjusts image positions and dimming areas to optimize visibility and reduce glare without requiring manual intervention
Solution Approach 2:
The patent enables dynamic repositioning of images and dimming areas in response to changing light conditions and user input, allowing the system to adapt to different environmental scenarios and user preferences

Function Achieved in This Case
The DPCS effectively mitigates sun glare and headlight glare by dynamically positioning and sizing images and dimming areas, enhancing driver safety and visibility while maintaining the ability to see traffic signals and other important information, and providing privacy shielding.
Implementation Method 1
otherwise transparent glass or plastic substrate materials have also been developed that are capable of reducing the visual transmissivity of an overall area via electrochromic means thereby controlling or regulating a transparency of the material
