Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a thin film is applied to glass to provide tint and reduce reflection, then light transmission and thermal properties are improved, but the ability to dynamically adjust tint properties is lost
Solution Approach 1:
The patent applies electrochromic technology to create a thin film that can dynamically change its optical properties from clear to tinted based on applied voltage. This allows the glass to adapt its tint properties in real-time, resolving the contradiction between static tint properties and dynamic adjustability.
Solution Approach 2:
The system changes the electrical parameter (voltage) applied to the electrochromic thin film to control its optical properties. By varying the voltage, the tint density can be adjusted dynamically, enabling adaptability without requiring complex mechanical or chemical replacement systems.
2Adaptability or versatility
If traditional glass tinting is used to reduce glare and provide privacy, then basic light control is achieved, but dynamic response to environmental conditions is not possible
Solution Approach 1:
The system incorporates sensors that detect environmental conditions (light levels, temperature, presence of people) and feed this information to a controller. The controller automatically adjusts the electrochromic thin film's tint properties based on the sensor feedback, enabling automatic adaptation to environmental conditions without manual intervention.
Solution Approach 2:
The system performs self-adjustment by using onboard sensors and controllers to automatically modify the glass tint properties based on detected environmental conditions, eliminating the need for manual operation while providing adaptive control.
3Adaptability or versatility
If electrochromic process is used to dynamically adjust tint, then adaptability is improved, but energy consumption increases
Solution Approach 1:
The system uses periodic or intermittent voltage application to the electrochromic thin film rather than continuous voltage. The tint is adjusted only when environmental conditions change or when requested, reducing energy consumption while maintaining the ability to dynamically adjust tint properties when needed.
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
The system provides improved control over light transmission, reducing glare on electronic devices, enhancing privacy by adjusting tint based on environmental conditions, and optimizing thermal properties, thereby improving user experience and energy efficiency.
Implementation Method 1
an electrochromic process can be utilized so that direct current (DC) voltage can be utilized to dynamically change the thin film from clear (e.g., no effect on incoming light) to tinted (e.g., effects a property of the incoming light such a reflection, color, etc.)
