Electrochromic Window Indicator for Transmissivity Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrochromic windows with variable transmissivity lack clear indication of intermediate transmissivity levels and transition states, making it difficult for users to notice incremental changes or progress.
Innovation Solution
Integration of a visual or acoustic indicator within the window that is controlled to show transmissivity levels or changes, using electrochromic material, lights, or other display technologies, allowing for passive or active control, and communication with user devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If an electrochromic device is used to provide variable transmissivity, then the window can control light transmission levels, but intermediate transmissivity levels and transition states are not clearly noticeable to users
Solution Approach 1:
The patent applies color change indicators that visibly display different colors corresponding to different transmissivity levels of the electrochromic device. This allows users to clearly perceive intermediate states and transition progress through distinct color changes, resolving the issue of unnoticed intermediate transmissivity levels while maintaining the variable transmissivity functionality
Solution Approach 2:
The patent implements a feedback mechanism where the visual indicator provides real-time information about the current transmissivity state and transition progress of the electrochromic device. This feedback loop enables users to understand the current state and monitor changes, addressing the information loss problem while preserving the adaptability of the electrochromic system
2Loss of information
If a visual indicator is integrated into the electrochromic window, then user awareness of transmissivity levels is improved, but the device complexity increases
Solution Approach 1:
The patent merges the visual indicator system with the electrochromic window structure by integrating the indicator between the panes of glass or within the window assembly. This combination approach provides clear visual feedback about transmissivity levels while minimizing additional structural complexity, as the indicator becomes part of the window's integrated design rather than a separate added component
