Display control for smart thermostat
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing smart thermostats often cause distractions and are not user-friendly due to fixed brightness levels and non-intuitive interfaces, leading to physical discomfort and energy inefficiency.
Innovation Solution
A smart thermostat with sensors (ambient light and radar) dynamically adjusts display brightness and content based on user proximity, movement, and viewing angle, featuring a dynamic lens assembly and intuitive input mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the display uses a fixed brightness level, then the device structure is simple, but it causes physical discomfort and distractions to users
Solution Approach 1:
The display brightness is made dynamic rather than fixed. The system continuously adjusts brightness based on real-time detection of user presence and environmental conditions, transforming a static parameter into a dynamically adaptive one to eliminate physical discomfort and distractions
Solution Approach 2:
The system implements feedback loops using sensors (ambient light sensors, proximity sensors, radar) to detect user presence and environmental conditions, then uses this feedback to automatically adjust display brightness, creating a closed-loop control system that adapts to user needs
2Ease of operation
If the display adjusts brightness dynamically based on user proximity and environment, then user comfort is improved, but energy consumption increases
Solution Approach 1:
The system applies partial action by adjusting display brightness only when and where needed (when users are present and would benefit from viewing), rather than continuously adjusting throughout the entire device operation, thus reducing unnecessary energy consumption
Solution Approach 2:
The system changes display parameters (brightness level) based on detected conditions, using sensor data to dynamically adjust only the necessary parameters when users are present, rather than maintaining high brightness continuously, thereby optimizing energy usage
3Adaptability or versatility
If the display content and characteristics are adjusted based on viewing angle and user behavior, then adaptability is improved, but device complexity increases
Solution Approach 1:
The system uses multi-functional sensors (ambient light sensors, proximity sensors, radar) that serve multiple purposes: detecting user presence, measuring environmental conditions, and determining viewing angles. This universal approach allows one sensor system to handle multiple detection tasks, reducing overall system complexity despite the sophisticated display adjustments
Solution Approach 2:
The display system automatically adjusts its own characteristics (brightness, content, viewing angle optimization) based on sensor input without requiring manual user intervention or complex external control systems, making the system self-regulating and reducing overall complexity

Data Source
AI summary
Features described herein pertain to smart thermostats, and more particularly, display control mechanisms for smart thermostats. A smart thermostat can include a display, an ambient light sensor, and a radar sensor. Using the ambient light sensor, an ambient light level of an environment surrounding the smart thermostat can be measured. Radar data can be received from the radar sensor, and based on the radar data, a determination can be made that a distance between a person and the smart thermostat has changed from a first distance to a second distance. In response, a display brightness of the display can be adjusted based on the ambient light level.
