Solution Overview
Problem
Conventional drying apparatuses face challenges in simultaneously operating high-temperature and low-temperature drying operations within a permissible current range, leading to potential damage of delicate clothes due to friction and inefficiencies in power usage.
Innovation Solution
A drying apparatus with a controller that reduces the heating performance of one drying device when both high-temperature and low-temperature operations are simultaneous, by adjusting the power supply to heaters and fan speeds based on laundry type and humidity, ensuring operation within an allowable current range.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple drying devices operate simultaneously at full heating performance, then drying efficiency and productivity are improved, but the current consumption exceeds the permissible range
Solution Approach 1:
The heating performance of drying devices is made dynamically adjustable rather than fixed. The controller continuously monitors current consumption and automatically adjusts the heating power of individual drying devices to maintain operation within permissible current limits while maximizing overall drying efficiency
Solution Approach 2:
The system changes the heating parameter (power output) of drying devices based on real-time conditions. When multiple devices operate simultaneously, the controller reduces the heating performance parameter of at least one device to ensure total current consumption remains within the permissible range
2Speed
If high temperature drying is used for cotton clothes, then drying speed is improved, but delicate garments may be damaged by heat and friction
Solution Approach 1:
The drying system is segmented into multiple independent drying devices that can operate simultaneously with different temperature settings. One device is dedicated to high-temperature drying for durable fabrics like cotton, while another operates at low temperature for delicate garments, allowing both to dry at optimal speeds without cross-contamination of harmful effects
Solution Approach 2:
Each drying device is configured with localized quality characteristics suited to specific fabric types. The first drying device provides high-temperature drying for robust fabrics, while the second drying device provides low-temperature drying for delicate fabrics, ensuring each material receives the appropriate thermal treatment to maximize drying speed while minimizing damage
