Cleaning Sheet Raised-Strip Structure for Dust Capture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaning sheets lack an effective mechanism for creating a space to capture dust during the cleaning process, which limits their cleaning efficiency.
Innovation Solution
A cleaning sheet with a holding region and a cleaning region, featuring a fiber bundle and a cleaning side sheet-like member with strips that can be raised to create a space for dust capture, utilizing engagement parts to maintain the raised position for enhanced dust collection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the cleaning sheet uses a simple structure without engagement parts, then the device complexity is reduced, but the ability to maintain the raised state of strips and fiber bundle constituent fibers deteriorates
Solution Approach 1:
The cleaning sheet is divided into multiple functional regions: a holding region with sheet elements and a receiving part for the holder, and a cleaning region with fiber bundle, cleaning side sheet-like member with strips, and bonding part. This segmentation allows each region to perform its specific function independently, maintaining structural complexity while ensuring reliable dust capture through the raised state mechanism
Solution Approach 2:
The engagement parts are integrated within the strip structure itself, where first engagement parts and second engagement parts are formed as inherent features of the strips. This nesting approach embeds the locking mechanism within the existing structure rather than adding separate components, thus maintaining raised state reliability without significantly increasing overall device complexity
2Volume of stationary object
If the cleaning sheet creates a larger space for dust capture by raising strips and fiber bundle constituent fibers, then the volume for dust collection is increased, but the device complexity increases due to engagement parts and bonding structure
Solution Approach 1:
The strips and fiber bundle constituent fibers are designed to be dynamically raiseable during cleaning operation. Users can raise these elements by holding both ends of the cleaning sheet and alternately moving hands up and down, or by shaking the holder. This dynamic capability creates a variable space for dust capture that expands during use, achieving increased effective volume without requiring a permanently complex structure
Solution Approach 2:
The physical state of the cleaning sheet components changes during operation. The strips and fiber bundle constituent fibers transition from a flat state to a raised state, changing the spatial parameters of the cleaning region. This parameter change allows the same structure to provide different volumes for dust capture depending on the operational phase, maximizing dust collection space without permanently increasing structural complexity

[Solution] Fiber bundle constituent fibers (B410) forming a fiber bundle (B400) and strips (B310) are configured to be bent along a bonding part (B710) so as to be raised up in a direction away from a holding region. It is configured such that, when a first strip (B321) and a second strip (B322) are raised, a first engagement part (B311a) can be engaged with the fiber bundle constituent fibers (B410), and a second engagement part (B312a) of the first strip (B321) and a second engagement part (B312a) of the second strip (B322) can be engaged with each other.
