Solution Overview
Problem
Existing methods for determining clothes dryness based on resistance measurement are inaccurate when clothes are dried unevenly, failing to account for varying humidity at different positions, leading to ineffective drying.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a resistance sensor is used to measure humidity of clothes, then the measurement process is simple, but the measurement precision is poor when clothes are dried unevenly
Solution Approach 1:
The measurement system is segmented into multiple electrode plates (at least two first electrode plates and at least two second electrode plates) positioned at different locations. Each electrode plate measures humidity at its specific position, allowing the system to capture spatial variations in humidity distribution throughout the clothes rather than relying on a single measurement point.
Solution Approach 2:
The invention transitions from a single-point measurement approach to a multi-dimensional measurement approach by distributing electrode plates throughout the treatment chamber. The rotatable treatment chamber enables measurements to be taken from multiple angular positions, adding a rotational dimension to the measurement space and comprehensively mapping humidity distribution.
2Measurement precision
If the treatment chamber rotates to multiple positions for measurement, then the measurement precision improves, but the measurement time increases
Solution Approach 1:
The treatment chamber rotates periodically to predetermined positions where measurements are taken. By rotating to specific angular positions (e.g., 0°, 90°, 180°, 270°) and taking measurements at each position, the system efficiently captures humidity distribution from multiple angles without requiring continuous rotation or excessive measurement points, thus balancing precision with time efficiency.
