Solution Overview
Problem
Existing window technologies do not effectively adjust light transmissivity based on geographic location, failing to comply with varying legal requirements across different jurisdictions.
Innovation Solution
A window assembly equipped with an electro-optic device, a geographic positioning system, and a controller that automatically or manually adjusts light transmissivity based on detected location, ensuring compliance with local regulations and user preferences.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the window uses a fixed light transmissivity setting, then the device complexity is reduced, but the adaptability to different geographic locations and legal requirements deteriorates
Solution Approach 1:
The window assembly integrates multiple functions into a single system: the electro-optic device serves both as a light control mechanism and a compliance device for different jurisdictions. The controller combines GPS functionality with transmissivity control, creating a universal system that adapts to various geographic locations and legal requirements without requiring separate dedicated components for each function.
Solution Approach 2:
The window system transitions from a static fixed transmissivity design to a dynamic adjustable system. The electro-optic device allows real-time modification of light transmissivity based on geographic location detected by GPS and user preferences, enabling the window to adapt its properties dynamically rather than being constrained to a single fixed state.
2Ease of operation
If the window allows full manual adjustment range, then the ease of operation is improved, but the compliance with local legal requirements deteriorates
Solution Approach 1:
The system incorporates feedback mechanisms where the controller continuously monitors the vehicle's geographic location via GPS and compares it against stored legal requirements for different jurisdictions. This feedback loop enables the system to automatically adjust the electro-optic device to comply with local laws while still allowing manual override within compliance boundaries, maintaining both ease of operation and legal reliability.
Solution Approach 2:
The controller acts as an intermediary between the user's manual adjustment desires and the legal compliance requirements. It mediates by allowing manual adjustment only within the legally permitted range for the current jurisdiction, blocking adjustments that would violate local laws, thus reconciling user convenience with legal obligations.
3Productivity
If the window automatically adjusts transmissivity, then the productivity is improved, but the device complexity deteriorates
Solution Approach 1:
The window system implements self-service functionality where the controller automatically detects geographic location via GPS, retrieves applicable legal requirements, and adjusts the electro-optic device transmissivity without requiring active user intervention. The system serves itself by autonomously making compliance decisions based on real-time location data and stored regulatory information.
Solution Approach 2:
The system performs preliminary actions by pre-storing legal transmissivity requirements for multiple jurisdictions in the controller's memory before travel. When the vehicle enters a new jurisdiction, the system has already have the compliance parameters ready, enabling immediate automatic adjustment without delay for information retrieval or manual configuration.

AI summary
A window assembly includes a window having an electro-optic device configured to limit light transmissivity through the window and a geographic positioning system. A controller is in communication with the geographic positioning system and is configured to limit a range of light transmissivity of the electro optic device based on a location detected by the geographic positioning system. A manual adjustment control configured to allow a user to adjust the light transmissivity of the window based on the range of light transmissivity provided by the controller.
