Station apparatus and operating method of station apparatus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cordless vacuum cleaners face limitations in dust collection capacity, leading to reduced cleaning performance due to blocked airflow when the dust container is full, requiring manual disassembly for cleaning, and existing station apparatuses either waste energy or discharge dust unnecessarily.
Innovation Solution
A station apparatus with a communication interface, suction motor, and processor that monitors suction power decrease in the cordless vacuum cleaner, automatically discharging dust when the decrease meets a pre-set threshold, optimizing cleaning performance and energy usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If the dust container is continuously used without emptying, then the cleaning operation duration is extended, but the suction power decreases and cleaning performance deteriorates due to blocked airflow
Solution Approach 1:
The station apparatus includes a processor that receives information about suction power decrease amount from the cordless vacuum cleaner through a communication interface. The system compares the suction power decrease amount with a pre-set threshold and automatically triggers dust discharge when the threshold is met, creating a closed-loop feedback mechanism that maintains optimal suction power throughout extended operation periods
Solution Approach 2:
The system performs dust discharge operation before the dust container becomes completely full and blocks the airflow path. By monitoring suction power decrease and triggering discharge when the pre-set threshold is reached, the system prevents performance degradation rather than reacting after blockage occurs, ensuring cleaning performance is recovered proactively
2Reliability
If the dust container is emptied frequently to maintain suction power, then the suction power is maintained, but the loss of time for emptying increases and productivity decreases
Solution Approach 1:
The station apparatus automatically performs the dust discharge operation without requiring user intervention. The processor monitors suction power levels, compares them against thresholds, and autonomously triggers the discharge mechanism when conditions warrant emptying, eliminating the need for users to manually empty the dust container and reducing time loss
Solution Approach 2:
The system uses real-time feedback from suction power monitoring to determine the optimal moment for dust discharge. Rather than following a fixed schedule or requiring manual checks, the system responds dynamically to actual performance conditions, emptying the container only when necessary to maintain suction power, thus minimizing interruptions and time loss
3Ease of operation
If the station apparatus discharges dust automatically without monitoring, then the operation is simplified, but energy is wasted and dust is discharged unnecessarily
Solution Approach 1:
The processor receives information about suction power decrease amount from the vacuum cleaner and compares this data against a pre-set threshold stored in memory. This feedback-based decision-making ensures the discharge operation is triggered only when actual performance degradation occurs, preventing unnecessary energy consumption from premature or excessive discharges while maintaining ease of automatic operation
Solution Approach 2:
Rather than continuously operating the discharge mechanism or using excessive energy to ensure complete emptying, the system applies just enough discharge action to restore suction power to acceptable levels. The processor triggers discharge only when the pre-set threshold is met, avoiding both insufficient and excessive discharge operations that would waste energy

Data Source
AI summary
A station apparatus performs a dust discharging operation when it is identified that a suction power decrease amount of a cordless vacuum cleaner is equal to or greater than a pre-set threshold suction power decrease amount, based on information about the suction power decrease amount of the cordless vacuum cleaner received from the cordless vacuum cleaner.
