Roller Assembly Tool With Self-Cleaning Suction and Fluid Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaning apparatuses lack an efficient method to capture and release debris materials from rollers, requiring frequent washing or replacement, and struggle to effectively utilize both suction and fluid delivery systems in a single tool.
Innovation Solution
A roller assembly with a support body and a roller having different surface tackiness materials, where the higher tackiness captures debris and the lower tackiness aids in release, combined with a fluid delivery system and suction assembly for continuous operation without manual cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a roller is used to capture debris materials, then cleaning effectiveness is improved, but the roller requires frequent washing or replacement due to debris accumulation
Solution Approach 1:
The roller assembly performs self-cleaning through the interaction of suction force and fluid delivery. The suction assembly removes debris from the roller surface while the fluid delivery system simultaneously refreshes the roller surface, eliminating the need for manual washing or replacement and enabling continuous operation
Solution Approach 2:
The system continuously discards captured debris materials through the suction assembly while recovering the roller's cleaning capability through fluid delivery that refreshes the roller surface, maintaining operational effectiveness without manual intervention
2Ease of manufacture
If a single material is used for the roller surface, then manufacturing is simplified, but the roller cannot effectively both capture and release debris materials
Solution Approach 1:
The roller surface is constructed with multiple materials having different surface tackiness properties in different regions. The higher tackiness material effectively captures debris materials while the lower tackiness material facilitates debris release, enabling continuous operation without manual cleaning
Solution Approach 2:
The roller employs a composite structure with multiple materials having different surface tackiness characteristics. This composite construction allows simultaneous debris capture and release functions, solving the contradiction between manufacturing simplicity and cleaning effectiveness
3Productivity
If suction and fluid delivery systems are combined in a single tool, then cleaning continuity is improved, but device complexity increases
Solution Approach 1:
The suction assembly and fluid delivery system are integrated into a single roller assembly tool. The suction assembly provides continuous debris removal while the fluid delivery system simultaneously refreshes the roller surface, enabling uninterrupted cleaning operation
Solution Approach 2:
The roller assembly serves multiple functions within a single tool: debris capture through the roller surface, debris removal through suction, and surface refreshment through fluid delivery. This multi-functionality enables continuous cleaning operation without requiring separate tools
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 continuous operation by capturing debris with high tackiness and releasing with lower tackiness, utilizing suction and fluid delivery to refresh the roller, reducing maintenance and improving cleaning efficiency.
Implementation Method 1
The roller includes a base with an outer surface constructed of a first material that has a first surface tackiness. A web feature is coupled to the outer surface. The web feature is constructed of a second material that has a second surface tackiness. The second surface tackiness is less than the first surface tackiness.
Implementation Method 2
A wand is coupled to the housing via an accessory hose. A roller assembly is selectively coupled to the wand. The roller assembly includes a support body having at least one guide and a roller rotatably coupled to the support body. Spacing between the at least one guide and a surface of the roller defines at least one inlet that is in fluid communication with the suction assembly
Implementation Method 3
A fluid delivery system is disposed within the housing. The fluid delivery system has a supply tank for housing a liquid. A fluid delivery assembly defines an outlet proximate the roller. The outlet is in fluid communication with the fluid delivery system via a conduit that extends through the support body and the wand.

AI summary
A roller assembly tool for a cleaning apparatus that includes a suction assembly and a liquid delivery system includes a support body carrying a portion of a liquid conduit and a portion of at least one airflow passage. The liquid conduit is configured to be in fluid communication with the liquid delivery system and the portion of the at least one airflow passage configured to be in fluid communication with the suction assembly. The support body includes first and second arcuate guides that define an open end. A roller is rotatably coupled to the support body proximate the open end. At least one inlet of the at least one airflow passage is defined between at least one of the first and second arcuate guides and a surface of the roller. An outlet of the liquid conduit is defined between the first and second arcuate guides proximate the roller.
