Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dimming glass systems lack the ability to adjust light transmittance in a manner that adapts to ambient brightness, leading to user discomfort such as dizziness and vision blocking.
Innovation Solution
A glass transmittance adjustment system that adjusts transmittance based on ambient brightness information using variable step sizes tailored to the current environment, allowing for smoother transitions and reducing user discomfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a fixed transmittance change step size is used for dimming glass adjustment, then the control method is simple, but user discomfort such as dizziness and vision blocking occurs
Solution Approach 1:
The patent applies dynamics by making the transmittance change step size variable rather than fixed. The step size dynamically adapts based on ambient brightness conditions: larger step sizes are used in bright environments for faster adjustment, while smaller step sizes are used in dark environments to prevent vision blocking and user discomfort.
Solution Approach 2:
The patent changes the parameter of transmittance adjustment step size based on ambient brightness information. The control device receives ambient brightness data and automatically selects appropriate step sizes from multiple predefined levels, transforming a static control parameter into a dynamic one that adapts to environmental conditions.
2Speed
If large transmittance change step size is used, then the adjustment speed is fast, but user discomfort such as dizziness occurs
Solution Approach 1:
The patent changes the transmittance adjustment step size parameter based on ambient brightness conditions. In bright environments, larger step sizes enable faster adjustment speed. In dark environments, smaller step sizes prevent user dizziness by providing gentler transitions. The system automatically selects the appropriate step size level based on received ambient brightness information.
3Object-affected harmful factors
If small transmittance change step size is used, then user comfort is improved, but the adjustment efficiency is low
Solution Approach 1:
The patent makes the transmittance adjustment step size dynamic rather than fixed. The system adapts the step size based on ambient brightness: using larger steps in bright conditions for high efficiency, and smaller steps in dark conditions for user comfort. This dynamic adaptation resolves the contradiction between speed and comfort.
Solution Approach 2:
The patent changes the adjustment step size parameter according to ambient brightness information, selecting from multiple predefined step size levels. This parameter adaptation enables the system to achieve both high efficiency (when using larger steps in bright environments) and user comfort (when using smaller steps in dark environments).
4Device complexity
If uniform transmittance adjustment is applied regardless of ambient brightness, then the control logic is simple, but the system cannot meet complex application environment needs
Solution Approach 1:
The patent changes the control parameter (transmittance step size) based on ambient brightness information. The control device receives brightness data and automatically selects appropriate step sizes from multiple levels, enabling the system to adapt to different ambient conditions without requiring complex manual configuration or multiple control modes.

AI summary
Disclosed are a glass translucency adjustment system and method, and a related device, which take into account ambient brightness information. Using a translucency single change step suited to the current ambient brightness information to adjust the translucency of dimmable glass, user discomfort such as dizziness can be avoided, and a situation in which the sight of the user is blocked can also be avoided. The system comprises: a translucency control apparatus, an instruction input interface of the light transmittance control device being configured to receive a translucency single adjustment instruction, wherein one translucency single adjustment instruction is used as an instruction for execution of a dimmable glass translucency adjustment operation according to a translucency single change step. The translucency control apparatus is configured to adjust the transparency of the dimmable glass according to the single change step of a target translucency, in response to the translucency single adjustment instruction, the target translucency single change step being a translucency single change step corresponding to the ambient brightness information.
