Clothes Treating Control Panel With Duty-Cycle LED Brightness Differentiation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional clothes treating apparatus control panels lack efficient methods to differentiate and display control commands through light emission units, leading to unclear user interfaces and reduced visibility of selected options.
Innovation Solution
The control panel employs a duty cycle control method for light emission units, where a target light emission unit emits brighter light than background units by varying the duty cycle of current supply, allowing for distinct brightness levels and improved visibility of control commands through a matrix of light emission units.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If uniform current is supplied to all light emission units, then manufacturing and control are simplified, but visibility and differentiation of control commands are reduced
Solution Approach 1:
The patent applies local quality by differentiating the duty cycle parameters for target light emission units versus background light emission units. Specifically, the controller sets a first duty cycle for target units and a second duty cycle for background units, creating localized variations in brightness that enhance control command visibility while maintaining a uniform physical structure and current supply mechanism across all units.
2Illumination intensity
If duty cycle is varied to create brightness differences, then control command visibility is improved, but control system complexity increases
Solution Approach 1:
The patent implements parameter changes by modifying the duty cycle parameter of the PWM signal supplied to different light emission units. The controller varies the duty cycle ratio between target units and background units to achieve brightness differentiation. This approach allows for effective visual distinction of control commands while maintaining relatively simple control logic through a single parameter adjustment rather than requiring complex multi-parameter control systems.
