Wheelbarrow Tool Support Shelf for Cleaner Concrete Tool Washing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The current methods for cleaning concrete tools are labor-intensive, time-consuming, and inefficient, particularly for large tools, and pose challenges in cold weather due to the need for frequent hand immersion in dirty water, leading to tool dropping and incomplete cleaning.
Innovation Solution
A concrete tool support shelf or rack is installed on a wheelbarrow, allowing tools to be cleaned out of water, with integrated brushes and filing surfaces for efficient tool handling and cleaning, and featuring flanges for secure attachment and easy transport.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If tools are cleaned by immersing them in water in the wheelbarrow basin, then cleaning is possible, but tools become dirty again and cleaning becomes time-consuming
Solution Approach 1:
The invention divides the cleaning process into separate functional zones: a dry cleaning area with brushes and scrapers for removing concrete material, and a wet rinsing area. This segmentation allows tools to be cleaned in stages without re-contamination, reducing the time tools spend in dirty water and improving overall cleaning efficiency.
Solution Approach 2:
The shelf structure acts as an intermediary platform that holds cleaning tools (brushes, scrapers) and provides a designated area for tool placement during cleaning. This intermediary structure organizes the cleaning process and prevents tools from being directly placed in dirty water, reducing re-contamination and cleaning time.
2Ease of operation
If tools are placed in water for cleaning, then concrete material can be removed, but tools can be dropped or knocked off and become dirty again
Solution Approach 1:
The cleaning area is segmented into a dry zone with brush holders and scraper mounting surfaces, and a wet zone. Tools are kept in the dry zone during cleaning operations, preventing them from being dropped into dirty water. Only during the final rinsing stage do tools contact water, maintaining their cleanliness and reducing the risk of re-contamination.
Solution Approach 2:
Cleaning tools (brushes, scrapers) are pre-positioned on the shelf structure before the actual cleaning process begins. This preliminary arrangement allows workers to immediately start cleaning without searching for tools, and keeps tools organized in a safe, dry location throughout the cleaning process, preventing drops and re-contamination.
3Productivity
If workers use two hands to hold brush and tool during cleaning, then cleaning effectiveness improves, but handling large tools becomes cumbersome
Solution Approach 1:
The invention combines multiple cleaning functions into a single integrated shelf structure: brush holders, scraper mounting surfaces, and tool resting areas are merged into one platform. This allows workers to attach brushes and scrapers to the shelf, freeing their hands to properly handle and position large tools during cleaning, thereby maintaining cleaning effectiveness while improving ease of operation with large equipment.
Solution Approach 2:
The shelf structure serves as an intermediary that holds cleaning implements (brushes, scrapers) during the cleaning process. This allows workers to use one hand to manipulate large tools while the cleaning implements remain securely attached to the shelf, maintaining cleaning effectiveness without the difficulty of two-handed operation with large equipment.
4Ease of operation
If the wheelbarrow basin is used as a wash basin, then tool cleaning is possible, but the basin becomes obstructed and transport becomes difficult
Solution Approach 1:
The shelf structure is designed as a separate, removable component that can be independently installed on or removed from the wheelbarrow basin. When removed, the basin remains completely unobstructed for transport and other uses. When installed, it provides the cleaning function. This segmentation allows the wheelbarrow to switch between transport mode and cleaning mode, maintaining both functions without permanent obstruction.
Solution Approach 2:
The shelf structure is designed to be dynamically configurable - it can be easily attached to the wheelbarrow when cleaning is needed and just as easily removed when transport is required. This dynamic design allows the wheelbarrow to adapt between different operational states (transport vs. cleaning) without permanent modifications or obstructions, maintaining both mobility and cleaning functionality.
