Solution Overview
Problem
Existing cleaner stations face inefficiencies in dust storage, lack of user-friendly dust amount visualization, and inconsistent user awareness of dust removal timing, leading to potential missed emptying times and inconvenience due to consumable dust bags.
Innovation Solution
A cleaner station with a compression unit that rotates a rotation plate to compress dust evenly, displays dust amount on a display unit, and calculates dust volume through rotation angle measurement, allowing flexible and accurate dust removal timing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a dust bag is used to store collected dust, then dust storage efficiency increases and the cycle between dust removal operations extends, but the dust bag is consumable and requires periodic replacement causing inconvenience and additional cost
Solution Approach 1:
The patent replaces the consumable dust bag with a permanent dust bin that can be repeatedly filled and emptied. The dust bin is designed to be durable and reusable, eliminating the need for periodic replacement of dust bags while maintaining effective dust storage capacity.
Solution Approach 2:
The system enables recovery and reuse of the dust bin itself. Instead of discarding the storage container after one use, the dust bin is designed to be emptied, cleaned, and refilled multiple times, transforming a single-use consumable into a reusable durable component.
2Extent of automation
If a canister dust bin with multi-stage separation device is used, then dust can be collected automatically, but the continuous airflow generated increases the volume of collected dust reducing storage efficiency
Solution Approach 1:
The patent extracts the dust collection function from the storage function. The cleaner performs dust collection automatically, and the dust is transferred to the dust bin for storage. This separation allows the storage container to be optimized for compact dust storage rather than being designed for continuous airflow and automatic separation.
Solution Approach 2:
The system uses periodic dust collection cycles rather than continuous operation. The cleaner operates intermittently to collect dust, which is then stored in the bin. This periodic approach allows dust to settle and be compacted efficiently without continuous airflow preventing density increase.
3Device complexity
If the rotation plate stops at the same position after each compressing process, then the control is simple, but the dust accumulates unevenly on one side of the rotation plate
Solution Approach 1:
The patent introduces asymmetric control in the rotation plate operation. Instead of stopping at the same symmetric position each time, the rotation plate alternates its stopping position between left and right sides. This asymmetric stopping pattern ensures that dust accumulates evenly on both sides of the rotation plate over multiple compression cycles.
Solution Approach 2:
The system implements periodic alternation of the rotation plate stopping position. The plate stops at alternating positions (left, right, left, right) in successive compression cycles. This periodic variation in stopping position prevents dust from accumulating preferentially on one side while maintaining relatively simple control logic.
