Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for applying grout between tiles and removing excess grout are labor-intensive and time-consuming, with existing tools being inefficient in handling large quantities or maintaining precision.
Innovation Solution
A grout installation apparatus featuring a grout applying member with a tank and dispensing head, and a grout removal member using a continuous belt with a spongy layer and scraper to efficiently apply and remove grout from tile surfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual methods are used to apply grout between tiles, then the process can be completed with simple tools, but the operation is labor-intensive and time-consuming
Solution Approach 1:
The patent combines the grout application function and excess grout removal function into a single integrated apparatus. The grout application member dispenses grout between tiles while the grout removal member simultaneously removes excess grout from tile surfaces, eliminating the need for separate manual operations and significantly improving productivity.
Solution Approach 2:
The apparatus performs multiple functions: it applies grout to tile joints, removes excess grout from surfaces, and can be operated with a single device rather than requiring multiple separate tools. This multi-functionality reduces the complexity of using multiple separate tools while maintaining high productivity.
2Productivity
If manual sponging is used to remove excess grout, then the process is simple to perform, but it is labor intensive and time consuming
Solution Approach 1:
The grout removal member is integrated with the grout application member, allowing simultaneous application and removal operations. This eliminates the need for separate manual sponging operations while maintaining ease of operation through a unified device that performs both functions automatically during a single pass.
3Quantity of substance
If conventional screwdrivers are used to scrape grout, then the tool is readily available, but only a small amount of excess grout can be removed at a time
Solution Approach 1:
The grout removal member features a wide scraping surface that can remove large quantities of excess grout in a single pass, unlike conventional screwdrivers. This increased removal capacity is achieved by integrating the removal function directly into the application apparatus with a broad contact surface, eliminating the need for repeated scraping motions.
4Productivity
If complex manual devices are used to remove excess grout, then more grout can be removed at once, but the device structure becomes complicated
Solution Approach 1:
The patent integrates the grout removal member directly with the grout application member in a unified apparatus. This integration allows the device to perform both application and removal functions simultaneously without requiring complex separate mechanisms, achieving high removal efficiency while maintaining relatively simple device structure through functional consolidation.

AI summary
A grout installation apparatus having a grout applying member and a grout removal member rearward of the grout applying member. The grout applying member includes a grout tank for storing grout, and a grout dispensing head which rests against an area of a tiled surface, confines said area and applies grout to the confined area to efficiently push grout into spaces between tiles. The grout applying member can include a user-operable piston to push the grout from the grout tank to the grout dispensing head. The grout dispensing head can include a rear squeegee for scraping and sweeping excess grout forward from the confined area of the tiled surface. The grout removal member wipes excess grout from the tile surface.
