Surface cleaning device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional surface cleaning devices often require a two-step process for cleaning, with sweepers and mops being ineffective for removing larger debris and leaving small particles behind, and struggle with debris tangling in rollers and wheels restricting movement, especially in hard-to-reach areas.
Innovation Solution
A surface cleaning device with a cleaning head, fluid tank, and a cleaning pad featuring a plurality of nozzles, where the fluid tank releases fluid onto the pad to facilitate one-step sweeping and mopping, utilizing a sweeper assembly with a debris container and a rotating brush to collect debris and a cleaning pad to remove both large and small particles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a two-step cleaning process is used (sweeper then mop), then large debris can be removed, but small particles remain on the surface requiring additional cleaning
Solution Approach 1:
The patent combines the sweeper and mop into a single integrated device that performs both functions simultaneously. The cleaning head includes both a roller brush for sweeping large debris and a cleaning pad for removing small particles, allowing both cleaning actions to occur in one pass rather than requiring separate sweeping and mopping steps
Solution Approach 2:
The cleaning device is designed with multi-functional capabilities to handle both large debris removal and small particle cleaning within a single device. The cleaning head can switch between or simultaneously perform sweeping functions with the roller brush and mopping functions with the cleaning pad, making one device sufficient for complete surface cleaning
2Reliability
If roller brushes are used to collect large debris, then sweeping effectiveness improves, but debris becomes tangled in the brushes preventing proper rotation
Solution Approach 1:
The roller brush is designed with flexible bristles that can dynamically adapt to debris of varying sizes and textures. The bristles are arranged to flex and move independently, allowing them to engage with and propel debris forward without becoming permanently tangled, maintaining rotational movement even when encountering challenging debris
Solution Approach 2:
The roller brush parameters such as bristle stiffness, length, and spacing are optimized to balance debris collection effectiveness with rotational freedom. The bristles are designed with specific mechanical properties that allow them to flex under debris load but return to their original position, preventing tangling while maintaining sweeping effectiveness
3Ease of operation
If wheels are added to allow movement over surfaces, then mobility is improved, but wheels restrict full rotation of the cleaning device in hard-to-reach areas
Solution Approach 1:
The patent removes traditional wheels from the cleaning device, extracting the mobility function and replacing it with a different mechanism. The cleaning head is designed to move freely across surfaces through direct user manipulation and the flexibility of its components, eliminating the rotational restrictions that wheels would impose in tight spaces
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
Enables efficient one-step cleaning of surfaces by effectively removing both large debris through sweeping and small particles through fluid distribution on the cleaning pad, improving cleaning efficiency and reducing the need for multiple cleaning tools.
Implementation Method 1
the fluid tank is configured to release at least some of the fluid such that the released fluid flows through the plurality of nozzles onto the cleaning pad
Implementation Method 2
a cleaning pad coupled to the cleaning head and configured to remove debris from a surface
