Washer-Dryer Hygiene Control Using Automatic Sterilization Timing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Fiber management apparatuses with integrated washers and dryers face hygiene management challenges due to user forgetfulness or unawareness, leading to contamination from foreign substances and bacteria accumulation in the drying unit.
Innovation Solution
A method for automatically activating the hygiene management mode of the drying unit when the washing unit is operated, using an external signal to synchronize or nonsynchronize the completion times of washing and hygiene operations, and performing sterilization and drying actions to maintain hygiene, even when unexpected situations occur.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the dryer has a function for removing foreign substances and bacteria, then hygiene management is improved, but the function is not executed automatically and requires user selection, leading to user forgetfulness or unawareness
Solution Approach 1:
The control unit automatically determines and executes the hygienic operation before the drying operation starts, based on detected foreign substances or bacteria. This preliminary action ensures hygiene management is performed proactively without requiring user intervention or awareness, resolving the contradiction between reliable hygiene management and automatic execution.
2Extent of automation
If the drying unit performs hygienic operation simultaneously with washing unit, then hygiene management is automated, but the drying unit may not be available immediately after washing
Solution Approach 1:
The control unit dynamically adjusts the timing of the hygienic operation based on the washing operation status. When the washing unit completes its operation, the control unit determines whether to execute the hygienic operation before or after the drying operation, optimizing the sequence to ensure the drying unit is available when needed while maintaining automated hygiene management.
Solution Approach 2:
The system changes the operational parameters by detecting foreign substances or bacteria and adjusting the timing and sequence of operations accordingly. When contamination is detected, the hygienic operation is prioritized and executed before the drying operation, ensuring hygiene while managing time loss through intelligent parameter adjustment.
3Reliability
If the drying unit performs sterilization and drying operations, then hygiene is improved, but energy consumption increases
Solution Approach 1:
The control unit applies the hygienic operation selectively based on local conditions - specifically when foreign substances or bacteria are detected in the drying unit. This localized approach ensures hygiene management is performed only when necessary rather than continuously, reducing unnecessary energy consumption while maintaining reliable hygiene management where needed.
