Multi-Door Home Appliance Color Synchronization Using LED Lighting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing home appliances often have doors with different colors and sizes that do not harmonize with each other, making it difficult to achieve a unified appearance when placed together.
Innovation Solution
A home appliance system with multiple doors that includes adjustable lighting devices to match colors and patterns, controlled by a control unit that synchronizes the lighting based on input from a server or mobile device, allowing doors to appear uniform in color and pattern.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If doors of different sizes and specifications are used in home appliances, then the home appliance can accommodate various storage needs and functionalities, but the exterior appearance becomes non-uniform and difficult to harmonize
Solution Approach 1:
The patent applies color-changing lighting devices (LEDs) installed on the doors to dynamically adjust the perceived color of each door. By controlling the lighting color and intensity, doors of different sizes and specifications can appear visually harmonized, resolving the exterior appearance non-uniformity issue while maintaining functional diversity
Solution Approach 2:
The system changes the optical parameters (color temperature, brightness, hue) of the lighting devices based on environmental conditions and user preferences. This allows the visual appearance of doors to be adjusted dynamically, creating a unified exterior appearance despite physical differences in door specifications
2Shape
If lighting devices are installed on each door to adjust color appearance, then exterior harmony can be achieved, but the device complexity and control system become more complex
Solution Approach 1:
The control unit is designed to universally control multiple lighting devices across different doors through a single interface. The system integrates environmental sensing, color matching algorithms, and lighting control into one multi-functional unit, reducing operational complexity despite the presence of multiple lighting devices
Solution Approach 2:
The system incorporates environmental sensors that detect ambient light conditions and automatically adjust the lighting device output accordingly. This feedback mechanism eliminates the need for manual adjustment of each lighting device, simplifying the control process while maintaining exterior harmony
3Shape
If multiple lighting devices are controlled to match colors across doors, then aesthetic harmony is improved, but the energy consumption increases
Solution Approach 1:
The lighting devices operate periodically rather than continuously, activating only when needed for aesthetic purposes (e.g., evening hours, when doors are closed). The control unit manages lighting cycles to maintain appearance harmony while minimizing energy consumption during periods when lighting is not required
Solution Approach 2:
The system dynamically adjusts lighting parameters (brightness, color temperature) based on ambient conditions and door position. When doors are open or ambient light is sufficient, lighting intensity is reduced or turned off, maintaining aesthetic harmony only when necessary and reducing overall energy consumption
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
Enables home appliances to display coordinated colors and patterns, enhancing their aesthetic harmony when placed side by side, regardless of differences in door specifications.
Implementation Method 1
a plurality of lighting devices provided in the doors, respectively, and configured to express a color of each door
Data Source
AI summary
A home appliance includes: a cabinet defining a storage space, a plurality of doors configured to open and close the storage space, a plurality of lighting devices provided in the plurality of doors, respectively, and configured to show a color of each door, and a control unit configured to control the plurality of lighting devices. The control unit is configured to, based on a color of one door of the plurality of doors being input, control the plurality of lighting devices to synchronize the colors of the plurality of doors to be the same.
