Door Ring Light-Emitting Assembly for Real-Time Laundry State Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing washing apparatuses have difficulty displaying the real-time operation state effectively, especially in conditions of long distance or poor night vision, due to limited functionality of their light-emitting door rings, which can only indicate washing and drying states inadequately.
Innovation Solution
A door-ring light-emitting assembly with a main trim and auxiliary trim arranged to form a channel for the light source, allowing light rays to escape and be reflected, creating a blooming effect that enhances visual range and display, featuring a simple and compact structure with low manufacturing cost.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a display screen is used to show processing state, then information display capability is improved, but visibility under poor night vision or at long distance deteriorates
Solution Approach 1:
The patent replaces the electronic display screen with an optical light-emitting system. The door ring light-emitting assembly uses light sources (LEDs or other illuminants) to display processing states through different light patterns, colors, or intensities, eliminating the need for electronic screens and improving visibility in dark environments without requiring external power for screen illumination.
Solution Approach 2:
The patent employs color-changing light-emitting elements to indicate different processing states. By varying the color, intensity, or pattern of emitted light, the system conveys multiple pieces of information (washing, drying, standby, error states) through a single optical interface that remains highly visible under all lighting conditions.
2Illumination intensity
If a light-emitting door ring is used to display processing state, then visibility is improved, but display functionality and real-time feedback capability deteriorate
Solution Approach 1:
The door ring light-emitting assembly is divided into multiple independent light-emitting segments or zones around the door perimeter. Each segment can be independently controlled to display different information, enabling complex real-time feedback about various operational states (water level, temperature, cycle progress, errors) through spatially distributed light patterns that maintain high visibility.
Solution Approach 2:
The system uses periodic or pulsing light emission patterns to encode real-time operational information. Different frequencies, durations, or sequences of light pulses convey different processing states, enabling dynamic feedback while maintaining energy efficiency and visual clarity.
3Illumination intensity
If trims are arranged to form a channel for light escape, then light escaping effect and visual range are improved, but device complexity increases
Solution Approach 1:
The patent integrates the light-emitting elements directly into the door ring trim structure itself, eliminating the need for separate light housings or complex mounting assemblies. The trim serves dual functions as both structural component and light-guiding element, with channels formed by the trim geometry to direct and escape light efficiently, thereby reducing overall device complexity while maintaining superior light escaping effect and visual range.
