Rotating Absorbent Pad Applicator for Tough Stain Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional stain treatment devices are ineffective in removing large tough stains from laundry items as they lack a combination of an effective stain removal formulation, applicator tip, and absorbent pad mechanism, and fail to scrub or absorb excess formulation, leading to incomplete stain removal.
Innovation Solution
A device with a fluid reservoir connected to an applicator valve assembly and an absorbent pad system that rotates to expose fresh pads, allowing for effective delivery, scrubbing, and absorption of the formulation, along with a translucent reservoir for formulation level indication and ergonomic design for easy use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional stain treatment devices are used, then small everyday stains can be treated, but large tough stains cannot be effectively removed due to lack of scrubbing surface
Solution Approach 1:
The device divides the cleaning function into separate components: an applicator tip for delivering formulation and an absorbent pad with scrubbing surface for mechanical action. This segmentation allows each component to be optimized for its specific function, enabling effective treatment of both small and large stains.
Solution Approach 2:
The device merges multiple functions into a single integrated system: formulation storage, formulation delivery, scrubbing, and absorption all occur in one device. This combination enables the device to handle various stain types and sizes effectively.
2Reliability
If discrete absorbent pads are used, then absorption function is provided, but the pad advancement mechanism is awkward and non-ergonomic
Solution Approach 1:
The pad advancement mechanism uses a rotating wheel design that allows dynamic, easy replacement of pads. Users can simply rotate the wheel to bring a fresh pad into position, making the operation ergonomic and convenient compared to discrete pad replacement.
3Reliability
If motorized stain removal brushes are used, then scrubbing function is provided, but formulation delivery and absorption functions are missing
Solution Approach 1:
The device is designed as a multi-functional system where a single component (the absorbent pad) performs multiple functions: scrubbing, absorption, and formulation distribution. This universal design eliminates the need for separate brushes and absorption materials.
4Ease of operation
If conventional devices are used, then formulation application is achieved, but excess formulation cannot be absorbed and stains cannot be effectively removed
Solution Approach 1:
The device combines formulation application and absorption functions in one integrated system. The absorbent pad is positioned to immediately absorb excess formulation after application, ensuring complete stain removal without leaving residue on the fabric.
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 device effectively loosens and removes large tough stains by combining a pre-spotting formulation with a scrubbing surface, absorbing excess formulation, and allowing for easy refilling and pad replacement, enhancing cleaning performance.
Implementation Method 1
an absorbent pad mechanism... absorbing excess formulation
Implementation Method 2
applicator tip for dispensing the functional formulation

AI summary
A device for applying a functional formulation to a surface is disclosed. The device includes a reservoir with a valve assembly for dispensing an effective stain removal formulation directly to the stain, spot or mark. The device also includes a shell accommodating absorbent pads. In use, the functional formulation is delivered through the applicator tip to the surface. The applicator is then rotated and one of the absorbent pads is engaged with the formulation treated surface to dislodge soils and stains on the surface, distribute the functional formulation on the surface, absorb excess formulation from the surface, and/or to lessen visibility of the resulting moistened area as well as reduce the time needed for the moistened area to dry. Suitable functional formulations for use in association with the applicator are also disclosed.
