Solution Overview
Problem
Existing cleaning devices are inefficient in handling both wet and dry debris, requiring multiple devices and frequent maintenance, and often become unsanitary or develop odors if not properly cleaned after use.
Innovation Solution
A cleaning device with a removably attachable head featuring a dirt collection chamber made of air filter material that absorbs and contains both wet and dry debris, allowing for single-device operation and reduced maintenance by disposing of the head without user contact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single cleaning device is used to handle both wet and dry debris, then device versatility is improved, but cleaning efficiency deteriorates
Solution Approach 1:
The cleaning device is segmented into a reusable power unit and disposable heads specialized for different debris types. Wet/dry heads have larger capacity chambers with drainage capabilities, while dry heads have smaller chambers optimized for dry debris collection. This segmentation allows each head type to be optimized for its specific function while sharing the same power unit.
Solution Approach 2:
The power unit is designed as a universal platform that can accept multiple types of disposable heads through a standardized connector system. This allows a single power unit to perform multiple cleaning functions by simply swapping heads, achieving versatility without compromising the performance of each specialized head.
2Ease of operation
If the cleaning device is designed for easy disposal of dirty components, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The head components are designed as disposable units that are discarded after use rather than cleaned and reused. This eliminates the complexity of cleaning mechanisms, seals, and maintenance procedures while providing extremely easy operation - users simply attach a new head when the current one is full or contaminated.
Solution Approach 2:
The disposable head is extracted as a separate, removable component from the main power unit. This allows the head to be easily detached and replaced without affecting the power unit, simplifying the disposal process while maintaining a relatively simple overall device structure through modular design.
3Reliability
If the dirt collection chamber is made of air filter material, then filtration capability is improved, but manufacturing complexity increases
Solution Approach 1:
The dirt collection chamber utilizes porous air filter material that allows air to pass through while trapping debris. This single material serves dual purposes: containing visible debris and filtering fine particles from the air stream. The porous structure is inherently suitable for both debris containment and air filtration without requiring additional filtering components.
Solution Approach 2:
The dirt collection chamber employs composite construction combining air filter material with structural support elements. This composite approach provides both the filtration properties of the porous air filter and the structural integrity needed for the chamber, achieving reliable filtration while maintaining manufacturability through a integrated design.

AI summary
Methods and apparatus for cleaning a surface with a cleaning device having a body with a handle, a connector, and one or more cleaning heads that are removably attached to the cleaning device. Each cleaning head include a lower surface arranged to contact a surface to be cleaned and a dirt collection chamber permanently attached to the cleaning head. The cleaning head may include a support structure to support the dirt collection chamber and a cleaning sheet. The cleaning head also may include a suction nozzle. At least a portion of the dirt collection chamber may be made of a filter material.
