Solution Overview
Problem
Existing household cleaning tools face challenges in effectively locking and unlocking rollers to replace dirty wipers with clean ones without the wiper sliding or coming loose during cleaning.
Innovation Solution
A cleaning tool design featuring a first and second roller, a shell, an operation part, and a link part, where the operation part moves axially to control the link part to unlock the second roller and rotate the first roller, utilizing elastic parts and a ratchet mechanism for controlled motion and locking, simplifying the operation process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the roller remains in a static state during cleaning, then the wiper will not slide or come loose, but the roller cannot be rotated to replace the wiper
Solution Approach 1:
The roller is designed to switch between static and rotatable states dynamically. During cleaning, the roller remains static to prevent wiper slippage. When wiper replacement is needed, the roller becomes rotatable through the link part mechanism, allowing the wiper to be rotated off and replaced with a new one.
Solution Approach 2:
The link part acts as an intermediary mechanism between the operation part and the roller. It transmits the rotational motion from the operation part to the roller, enabling the roller to switch between locked and rotatable states, thus mediating between the need for stability and the need for replaceability.
2Ease of operation
If the roller is made rotatable to enable wiper replacement, then the wiper can be changed easily, but the wiper will slide and come loose during cleaning
Solution Approach 1:
The roller transitions from a permanently rotatable state to a dynamically controllable state. Through the link part and operation part mechanism, the roller can be locked in a static position during cleaning to prevent wiper slippage, and unlocked to rotate for wiper replacement, thus dynamically adapting to different operational requirements.
Solution Approach 2:
The link part serves as a mediator that controls the roller's rotatability. It receives input from the operation part and translates it into locking or unlocking actions on the roller, thereby mediating between the user's operational needs and the roller's mechanical state.
3Reliability
If separate mechanisms are provided for locking/unlocking and rotation, then each function can be optimized, but the device complexity increases
Solution Approach 1:
The operation part combines both locking/unlocking and rotation functions into a single component. By rotating the operation part, it simultaneously performs the locking/unlocking action on the roller through the link part, and also drives the roller rotation, thus merging two functions into one integrated mechanism.
Solution Approach 2:
The operation part is designed as a multi-functional component that can perform multiple operations: it locks/unlocks the roller through the link part mechanism, and also rotates the roller directly. This universal component eliminates the need for separate mechanisms, reducing overall device complexity while maintaining functional reliability.

Function Achieved in This Case
Enables easy and efficient unlocking and rotation of rollers, allowing for seamless wiper replacement and maintenance of the cleaning tool's tensioned state during use, enhancing user experience and operational simplicity.
Implementation Method 1
the cleaning tool further comprises a first elastic part, wherein the first elastic part applies a force to the operation part to enable the operation part to return
Implementation Method 2
the cleaning tool further comprises a second elastic part, wherein the second elastic part is connected to the shell and the link part and applies a force to the link part to enable the link part to lock or unlock the second roller

AI summary
A cleaning tool is provided. The cleaning tool includes a first roller, a second roller, a shell and a wiper. The first roller is rotatably connected to the shell. The second roller is rotatably connected to the shell. Two ends of the wiper are wound around the first roller and the second roller, respectively. The cleaning tool further includes an operation part and a link part. The operation part moves in an axial direction of the first roller to control the link part to unlock the second roller and the operation part rotates to drive the first roller to rotate. Unlocking of the second roller and rotation of the first roller and the second roller are controlled by different motions of the operation part.
