Automatic self-wringing microfiber cleaning sponge on an extendable handle
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hand-held cleaning devices with compressible sponges require the use of two hands for wringing, are complex in design, and often limit maneuverability, making them inefficient for single-handed use and effective cleaning.
Innovation Solution
A cleaning device with an extendable ergonomic handle featuring a push button self-wringing actuator, which includes a spring back hinge mechanism that allows for one-handed operation by depressing a push button to squeeze and wring the sponge, and returns to its original position for continued cleaning, enhancing maneuverability and ease of use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional wringing mechanisms are used, then wringing function is achieved, but device complexity increases and requires two hands for operation
Solution Approach 1:
The spring mechanism automatically returns the wringing chamber to its initial position after wringing, eliminating the need for manual repositioning. The system serves itself by using the stored elastic energy in the spring to reset the mechanism, enabling continuous one-handed operation without complex control systems
Solution Approach 2:
The push button mechanism extracts and isolates the wringing activation function from the main handle, allowing independent control of the wringing action with the thumb while the other fingers maintain grip on the handle. This separation enables one-handed operation without requiring complex multi-component control mechanisms
2Adaptability or versatility
If rigid handles with multiple brackets and rails are used, then wringing capability is achieved, but maneuverability is limited
Solution Approach 1:
The handle incorporates a telescopic section that allows dynamic adjustment of handle length, adapting to different user preferences and cleaning scenarios. This dynamic adjustment mechanism replaces rigid fixed-length handles with multiple brackets, providing versatility without requiring complex mounting structures
Solution Approach 2:
The handle is divided into segmented sections including a fixed portion and a telescopic portion that can move relative to each other. This segmentation allows the handle to adapt to different usage requirements while maintaining structural simplicity, avoiding the need for multiple rigid brackets and rails
3Ease of operation
If conventional wringing mechanisms are used, then sponge compression is achieved, but user convenience decreases due to manual repositioning required
Solution Approach 1:
The spring mechanism automatically returns the wringing chamber to its initial position after wringing, eliminating the need for manual repositioning. The system serves itself by using the stored elastic energy in the spring to reset the mechanism, enabling continuous one-handed operation without time loss for manual intervention
Solution Approach 2:
The spring is pre-loaded and stores elastic energy in advance, ready to automatically return the wringing chamber to its initial position after compression. This preliminary preparation of the return mechanism eliminates the need for manual repositioning actions during operation

AI summary
A cleaning device may include an extendable ergonomic handle having a fixed handle member and a telescoping handle member. The fixed handle member may be secured at its lower distal end to a mounting plate. The mounting plate may include two plate members connected by a hinge. A sponge may be removably connected to the mounting plate. The cleaning device may include a close and release mechanism housed within the handle members operatively connected to the hinged plate members. The close and release mechanism may be actuated to squeeze and wring out the sponge and thereafter return it to a cleaning configuration.
