Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional clothes dryers lack energy efficiency and effective sterilization quality due to the lack of differentiation in sterilization processes based on the dry state of the object being dried, leading to suboptimal energy usage and sterilization outcomes.
Innovation Solution
A clothes dryer system that employs sensors to detect the dry state of the object and adjusts the sterilization process accordingly, utilizing different temperature maintenance strategies and fan rotation speeds to optimize energy use and sterilization effectiveness through distinct sterilization courses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a sterilization course is performed collectively without discriminating the state of the object to be dried, then the sterilization process is simple, but energy efficiency for the sterilization quality and sterilization course is lowered
Solution Approach 1:
The patent applies dynamics by making the sterilization process adjustable and adaptable based on real-time detection of the object's state. The system dynamically switches between different sterilization courses (first course for wet objects, second course for dry objects) based on sensor feedback, allowing the process to optimize energy consumption according to actual conditions rather than following a fixed collective procedure
Solution Approach 2:
The patent implements parameter changes by modifying sterilization parameters (temperature, time, fan speed) based on the detected state of the object. The processor adjusts the sterilization course parameters dynamically - using higher temperatures and different timing for wet objects versus dry objects - thereby optimizing energy efficiency while maintaining sterilization quality
2Ease of operation
If a sterilization course is performed collectively without discriminating the state of the object to be dried, then the control process is simple, but sterilization quality is compromised
Solution Approach 1:
The patent implements feedback by using sensors to detect the state of the object to be dried and using this information to automatically adjust the sterilization course. The system continuously monitors the object's state and provides feedback to the processor, which then selects the appropriate sterilization course (first or second course), ensuring reliable sterilization quality while maintaining ease of operation through automatic control
Solution Approach 2:
The patent applies self-service by enabling the system to automatically determine and adjust the sterilization parameters based on the object's state without requiring manual intervention. The sensor-based detection and automatic course selection allow the system to self-optimize the sterilization process, maintaining both simplicity and reliability
