Flexible Scrubbing Pad Assembly for Corners and Narrow Grooves
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cleaning devices with replaceable heads struggle to effectively clean corners and narrow grooves due to their design, and they become dirty and smelly, with inadequate storage solutions and high costs for components.
Innovation Solution
A multi-layer cleaning pad with an upper layer for hook/loop fastening, an interior layer impregnated with a cleaning solution, and a lower abrasive layer, combined with a flexible ergonomic handle and a container system for efficient storage and shipping, allowing for repetitive use and cost-effectiveness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional cleaning devices with replaceable heads are used, then they can be used to clean surfaces, but they cannot effectively clean corners and narrow grooves due to their design
Solution Approach 1:
The cleaning device is divided into a handle and a replaceable pad assembly. The pad assembly can be further separated into individual pads that can be attached to the handle as needed. This segmentation allows the user to select appropriately sized pads for different cleaning tasks, including corners and grooves, without requiring completely different devices.
Solution Approach 2:
The invention introduces a compact, foldable pad design that can be collapsed to a minimal profile for storage in the handle housing, yet expands to provide adequate cleaning surface area when deployed. This dimensional transformation enables effective cleaning of narrow spaces while maintaining a compact form factor.
2Ease of operation
If conventional scrub brushes are used to clean corners and grooves, then they can effectively clean these areas, but they become dirty and smelly over time and drip after use
Solution Approach 1:
The invention employs disposable or easily replaceable cleaning pads that are discarded after use or when soiled, eliminating the hygiene problems associated with reusable brushes. The pads are designed to be inexpensive enough that replacement is practical, ensuring users always have clean pads available without maintaining soiled brushes.
Solution Approach 2:
The cleaning function is extracted from the handle into separate, removable pads. This allows the handle to remain clean and dry while the pads bear the brunt of the cleaning work and can be easily removed for replacement, preventing the handle itself from becoming contaminated.
3Ease of operation
If replaceable cleaning heads with small handles are used to create compact hand-held devices, then they can clean corners better, but the cleaning heads and handles become unduly expensive
Solution Approach 1:
The device is segmented into an expensive, durable handle and inexpensive, disposable pads. This allows the costly components to be reused while only the consumable pads need frequent replacement, significantly reducing overall operating costs compared to completely replaceable head systems.
Solution Approach 2:
The handle is designed as a universal platform that can accommodate multiple types of pads for different cleaning tasks. This multi-functionality justifies the higher initial handle cost by eliminating the need to purchase multiple specialized tools, while keeping individual pad costs low.
4Ease of operation
If conventional cleaning devices are used, then they can perform cleaning functions, but they lack optimal storage systems for the handle and replacement pads between usage
Solution Approach 1:
The storage system employs a nested configuration where the replaceable pads are stored inside the handle housing when not in use. This integrated storage eliminates the need for separate containers or bags, providing a compact, self-contained system that is convenient for transport and storage.
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 system efficiently cleans tight corners and narrow grooves while maintaining a high concentration of cleaning solution across multiple uses, with a cost-effective and compact storage solution for the handle and pads.
Implementation Method 1
an interior layer impregnated with a cleaning solution
Implementation Method 2
the upper, interior and lower layers are welded together or needle punched together around their periphery
