Solution Overview
Problem
Existing dishwashers lack efficient and cost-effective optical detection methods to accurately assess the loading and soiling conditions within the washing chamber, requiring multiple fixed detection means to achieve reliable detection.
Innovation Solution
A rotatably mounted optical detection means that can capture different sections of the washing chamber from various angles, allowing for automatic adaptation of washing programs based on the detected state, eliminating the need for multiple static detection systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple fixed optical detection means are installed to detect different sections of the washing chamber, then the detection coverage is improved, but the device complexity and cost increase
Solution Approach 1:
The patent combines multiple detection functions into a single optical detection means by mounting it on a rotatable support structure. This allows one detection device to cover multiple spatial sections of the washing chamber through rotation, eliminating the need for multiple fixed detection means and reducing system complexity while maintaining comprehensive detection coverage
Solution Approach 2:
The optical detection means is mounted on a rotatable support that can change its angular position dynamically. This dynamic positioning capability allows the single detection device to scan different sections of the washing chamber, transforming a static limited-coverage system into a dynamic comprehensive-coverage system without increasing the number of devices
2Device complexity
If a single fixed optical detection means is used, then the device complexity is reduced, but the detection coverage and reliability are insufficient
Solution Approach 1:
The rotatable mounting mechanism enables the single optical detection means to dynamically access different spatial sections of the washing chamber. By rotating to different positions, the detection device can comprehensively assess the loading state across all sections, improving detection reliability while maintaining simple device architecture
Solution Approach 2:
The single optical detection means is designed with multi-functionality through its rotatable mounting, allowing it to perform detection tasks across multiple locations and angles. This universal detection capability replaces what would traditionally require multiple specialized detection devices, achieving reliable comprehensive detection with a single versatile unit
