Solution Overview
Problem
Current cleaning tools, such as pressure washers and crevice brushes, fail to effectively remove debris from narrow spaces between brick pavers without disturbing the substrate, often requiring multiple cleanings and potentially damaging the paver joints.
Innovation Solution
A vacuum attachment tool with a hollow body and a scrapper portion that attaches to a vacuum hose, featuring a v-shaped protruding edge to engage chamfered crevices, allowing for efficient debris removal without disturbing the substrate beneath.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If pressure washers or crevice brushes are used to clean debris from narrow spaces between pavers, then debris removal capability is improved, but substrate disturbance occurs and jointing sand is removed
Solution Approach 1:
The cleaning tool is segmented into distinct functional components: a scrapper portion with a v-shaped leading edge for debris removal, and a suction path for vacuuming. This segmentation allows the scrapper to remove debris while the suction path captures it immediately, preventing substrate disturbance while maintaining effective cleaning capability.
Solution Approach 2:
The scrapper portion acts as an intermediary between the vacuum and the debris in narrow spaces. The v-shaped leading edge of the scrapper engages with and removes debris from chamfered crevices, while the suction path simultaneously vacuums the loosened debris, preventing it from falling back onto the substrate and avoiding jointing sand removal.
2Productivity
If current cleaning tools are used on chamfered crevices, then some debris is removed, but multiple cleanings are required due to incomplete removal
Solution Approach 1:
The tool merges the scrapper function and suction function into a single integrated device. The scrapper portion with its v-shaped leading edge is positioned directly within the suction path, allowing simultaneous mechanical debris removal and vacuum capture in one passing motion, thereby completing the cleaning task in a single operation rather than requiring multiple cleanings.
Solution Approach 2:
The scrapper portion performs preliminary action by mechanically loosening and removing debris from the chamfered crevices before the suction path captures it. This preliminary mechanical action ensures complete debris removal in one pass, eliminating the need for repeated cleanings to achieve the same result.
3Productivity
If pressure washers are used to penetrate deep into crevices, then debris removal is enhanced, but jointing sand is removed resulting in unstable pavers
Solution Approach 1:
The invention replaces the high-pressure mechanical impact of pressure washers with a gentler mechanical scrapper action combined with vacuum suction. The scrapper portion with its v-shaped leading edge mechanically removes debris through controlled scraping motion, while the suction path simultaneously vacuums the loosened debris, achieving effective debris removal without the forceful penetration that removes jointing sand and compromises paver stability.
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 vacuum attachment tool effectively removes debris from narrow spaces between pavers by using suction and a v-shaped scrapper, ensuring the substrate remains undisturbed and requiring fewer cleanings.
Implementation Method 1
