Solution Overview
Problem
Existing dryers require user effort to clean filters due to adhered foreign materials, which can lead to inadequate airflow and a risk of fire, as well as frequent maintenance, compromising user convenience and safety.
Innovation Solution
A dryer with a cyclone-based foreign material removing apparatus that automatically separates and stores foreign materials in a removable case, maintaining airflow and reducing the need for frequent filter cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a filter is used to remove foreign materials from air, then foreign materials are separated from the air, but the filter requires frequent manual cleaning and user effort
Solution Approach 1:
The patent extracts the foreign material removal function from the traditional filter system. Instead of using a filter that requires cleaning, the invention introduces a cyclone separator that automatically removes foreign materials from the air stream without requiring user intervention for maintenance.
Solution Approach 2:
The cyclone separator performs self-cleaning by design. The centrifugal force generated by the cyclone flow automatically separates and discharges foreign materials without requiring user effort, making the system self-maintaining and eliminating the need for manual filter cleaning.
2Object-affected harmful factors
If foreign materials are removed by a traditional filter, then air is filtered, but airflow is blocked when foreign materials accumulate
Solution Approach 1:
The patent uses pneumatic principles through the cyclone separator, which utilizes centrifugal force generated by rotating air flow to separate foreign materials. This pneumatic separation method prevents blockage of airflow paths while continuously removing contaminants, maintaining reliable air circulation.
Solution Approach 2:
The cyclone separator continuously discards foreign materials from the air stream through automatic discharge mechanisms. By constantly removing separated foreign materials, the system prevents accumulation that would block airflow, thereby maintaining continuous and reliable air circulation.
3Object-affected harmful factors
If foreign materials adhere to the filter, then foreign materials are captured, but cleaning becomes difficult and troublesome
Solution Approach 1:
The patent replaces the mechanical filter system with a cyclone separator that uses centrifugal force for separation. This substitution eliminates the need for manual mechanical cleaning operations, as the cyclone design allows foreign materials to be automatically discharged without user intervention.
Solution Approach 2:
The cyclone separator is designed to be self-maintaining through automatic discharge of foreign materials. The system performs its own cleaning function by utilizing the centrifugal separation process to continuously eject captured foreign materials, eliminating the need for user effort in cleaning operations.
