Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mop dewatering devices require users to step on a pedal and balance, making the operation inconvenient and unsafe, especially for those who struggle to stand stably.
Innovation Solution
A telescopically rotatable mop design featuring an internal and external rod system with a driving element and locking mechanism that allows for one-handed operation, utilizing a centrifugal force to remove water from mop yarns without the need for foot pedals, enabling continuous rotation and reducing effort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a pedal is provided for driving a gear to rotate a dewatering tank, then the dewatering function is improved, but the operation convenience and safety deteriorate because the user must step on the pedal continuously and maintain body balance
Solution Approach 1:
The patent removes the foot pedal and body balance requirements from the dewatering operation. The user simply needs to hold the mop handle with one hand, and the dewatering mechanism operates automatically through the rotational motion of the mop head, extracting the harmful requirement of continuous foot pressure and balance maintenance.
Solution Approach 2:
The dewatering mechanism is designed to operate automatically once the mop is inserted into the dewatering tank. The rotational motion of the mop head self-activates the gear mechanism and dewatering tank rotation, eliminating the need for continuous user intervention or foot pressure on a pedal.
2Stability of the object's composition
If the internal rod and external rod are connected tightly, then the structural stability is improved, but the telescopic operation becomes difficult and friction increases
Solution Approach 1:
The patent applies different quality characteristics to different parts of the rod connection. The locking mechanism provides tight engagement and stability when locked, while the telescopic portion maintains a precise gap for smooth movement. This local differentiation of connection quality resolves the contradiction between stability and operational smoothness.
Solution Approach 2:
The connection between internal and external rods transitions from a static tight connection to a dynamic system with controlled clearance. The gap allows for smooth telescopic motion during operation, while the locking mechanism dynamically engages to provide stability when needed, adapting the connection quality to the operational state.
3Productivity
If the annular element rotates freely at 360°, then the dewatering efficiency is improved, but the positioning precision deteriorates
Solution Approach 1:
The patent employs periodic locking and unlocking of the annular element during the dewatering cycle. The element rotates freely during the dewatering phase to maximize efficiency, then locks periodically to maintain positioning. This periodic alternation between free rotation and locked positioning resolves the contradiction between dewatering efficiency and positioning precision.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design allows for safe, convenient, and efficient dewatering with reduced effort, minimizing operation failures and extending the service life of the mop by enabling smooth telescopic and rotary motion with less friction and noise.
Implementation Method 1
a centrifugal force is produced to throw away the water absorbed in the mop yarns
Implementation Method 2
thereby creating a continuous rotation of the internal rod and the disc body in the same direction by the inertia force

AI summary
A telescopically rotatable mop, comprising: an internal and external rod fitting to each other in a linearly and telescopically movable state; an engaging element positioned within the opening at the top of the internal rod; a driving element formed in an elongated shape and positioned within the external rod in such a way that the driving element is moved up and down synchronically with the external rod; an actuating element positioned within the engaging element for accommodating the driving element, the engaging element being driven in a single direction when the actuating element is rotated by the driving element. An annular element rotatable clockwise and counterclockwise at 360° is mounted on the top portion of the engaging element. The actuating element received within the engaging element has a smaller length, thereby creating a gap for the lifting and lowering purposes. In this way, a more smooth operation with less effort is ensured when the internal and external rods rotate in a telescopic way.
