Solution Overview
Problem
Conventional drying apparatuses require separate operations for high-temperature and low-temperature drying of clothes with different materials, leading to inefficiencies and potential damage to delicate items due to friction during rotational tumbling, and they often exceed the permissible current range when multiple drying devices are used simultaneously.
Innovation Solution
A drying apparatus comprising a first drying device with a basket and a first heater, and a second drying device with a drum and a second heater, controlled by a controller that reduces the heating performance of one or both heaters to operate within an allowable current range, allowing simultaneous operation of both devices while adjusting fan speed based on humidity, temperature, and laundry type.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple drying devices are operated simultaneously, then productivity is improved, but the current consumption exceeds the permissible range
Solution Approach 1:
The patent implements dynamic control of heater power output based on real-time current monitoring. When multiple drying devices operate simultaneously and current approaches the permissible limit, the system automatically adjusts heater power levels to maintain operation within safe electrical constraints while preserving drying functionality.
Solution Approach 2:
The system changes operational parameters by adjusting heater power consumption dynamically. By modulating the heating element output based on current load conditions, the apparatus enables simultaneous operation of multiple drying devices without exceeding electrical circuit capacity, thus resolving the contradiction between productivity and energy usage.
2Productivity
If high temperature drying is used for cotton clothes, then drying efficiency is improved, but delicate garments may be damaged
Solution Approach 1:
The patent applies different heating conditions to different drying devices or zones. Each drying device can be independently controlled to provide appropriate temperature levels for specific fabric types, with high-temperature zones for cotton and low-temperature zones for delicate garments, thereby preventing heat damage while maintaining drying efficiency.
Solution Approach 2:
The system segments the drying function into multiple independent drying devices, each capable of operating at different temperature levels. This segmentation allows cotton clothes to be dried at high temperature while delicate garments are dried at low temperature simultaneously, resolving the contradiction between drying efficiency and fabric protection.
3Manufacturing precision
If rotational tumbling is used for drying, then drying uniformity is improved, but delicate clothes may be damaged by friction
Solution Approach 1:
The patent applies different mechanical treatment modes to different drying devices. While one drying device uses rotational tumbling for cotton clothes to achieve uniform drying, another drying device uses stationary or gentle air circulation for delicate garments to avoid friction damage, allowing both drying uniformity and fabric protection to be achieved simultaneously.
