Solution Overview

Problem

Current washing equipment with integrated drying systems lacks a solution for detecting and prompting users about decreased resistance in the drying system, leading to reduced airflow rates and affected drying efficiency due to wear and lint accumulation.

Innovation Solution

A method and device that determine the resistance state of the drying system based on the weight and temperature of washings, using a temperature sensor to adjust airflow rates and send prompt information when an abnormal resistance state is detected, ensuring efficient drying and user maintenance alerts.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the drying system operates continuously without monitoring, then the equipment structure remains simple, but the drying efficiency decreases due to un detected resistance changes

Engineering Contradiction:
Improvedrying efficiencyVSAvoidsystem complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent implements feedback by using a temperature sensor to continuously monitor the temperature inside the drying system and comparing it with a preset threshold. When the temperature exceeds the threshold, indicating abnormal resistance, the system sends a prompt message to the user's terminal device. This feedback mechanism enables the system to detect and respond to resistance changes, maintaining drying efficiency without requiring complex additional hardware.

Inventive Principle:
Principle #23Feedback

2Reliability

If the system monitors resistance continuously, then the drying efficiency is maintained, but the device complexity increases

Engineering Contradiction:
Improvesystem reliabilityVSAvoidmonitoring system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent applies self-service by utilizing the existing temperature sensor within the drying system for dual purposes: both for normal temperature monitoring during operation and for detecting abnormal resistance conditions. The system automatically compares the temperature with the preset threshold and triggers prompts when needed, without requiring separate dedicated monitoring hardware. This approach enhances system reliability while avoiding additional complexity.

Inventive Principle:
Principle #25Self-service

3Productivity

If the airflow rate is increased to maintain drying efficiency, then the drying performance improves, but the energy consumption increases

Engineering Contradiction:
Improvedrying efficiencyVSAvoidenergy consumption
Core Design Contradiction:
ProductivityVSUse of energy by moving object

Solution Approach 1:

The patent implements preliminary action by detecting temperature changes that indicate rising resistance before they significantly impact drying efficiency. By monitoring the temperature and comparing it with the preset threshold, the system can alert users in advance to clean or maintain the drying system. This proactive approach allows users to address resistance issues before they cause substantial efficiency loss, avoiding the need to continuously increase airflow rate and consume extra energy.

Inventive Principle:
Principle #10Preliminary action
