Solution Overview
Problem
Existing concrete floor polishing machines are labor-intensive and pose environmental concerns due to air pollution and the inability to safely operate indoors, as they fail to effectively collect dust and sludge.
Innovation Solution
A polishing machine with integrated systems for dust and slurry collection, featuring a hydraulic pump-driven vacuum system, swivel-mounted polishing head, and interchangeable wet/dry configurations, which includes a squeegee with a built-in suction channel for efficient slurry management and dust containment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional concrete floor polishing machines are used, then polishing efficiency is improved, but dust and slurry are not effectively collected causing air pollution and unsafe indoor operation
Solution Approach 1:
The patent combines the polishing function with dust and slurry collection functions into a single integrated machine. The polishing head is merged with a vacuum system that includes a cyclone separator and collection container, allowing simultaneous polishing and dust extraction without requiring separate equipment.
Solution Approach 2:
The patent introduces a cyclone separator as an intermediary device between the polishing head and the collection container. This cyclone uses centrifugal force to separate dust and slurry from the air stream, effectively capturing harmful particles while allowing clean air to be discharged.
2Object-affected harmful factors
If dry polishing is used to reduce slurry, then air quality deteriorates due to increased dust, but if wet polishing is used to reduce dust, then slurry management becomes more complex
Solution Approach 1:
The patent designs a universal collection system that can handle both dust and slurry through a single integrated container and cyclone separation mechanism. The same vacuum system and cyclone separator effectively manage different types of particulate matter regardless of whether wet or dry polishing is used.
Solution Approach 2:
The patent changes the physical parameters of the collection system by using a cyclone separator that operates on centrifugal force rather than simple filtration. This allows the system to handle varying viscosities and densities of dust and slurry effectively, adapting to different polishing conditions.
3Adaptability or versatility
If multiple separate machines are used for polishing and dust collection, then functional versatility is improved, but device complexity and labor requirements increase
Solution Approach 1:
The patent merges multiple functions (polishing, dust collection, slurry management) into a single integrated machine, eliminating the need for separate polishing machines and vacuum systems. This reduces the number of components while maintaining full functional versatility.
Solution Approach 2:
The integrated machine performs multiple functions simultaneously: polishing the concrete floor, collecting dust through the cyclone separator, and managing slurry through the same collection system. The machine is universally applicable to different polishing conditions without requiring additional equipment.

AI summary
A floor polishing machine for concrete includes a frame with an integrated hydraulic fluid tank, a hydraulic drive system, and a hydraulic pump vacuum system. Further, the machine provides a swivel polishing head that provides abutting contact with a floor and includes a floating ring and rubber skirts that seals the polishing head. The machine provides interchangeable wet and dry vacuum systems for collection of the slurry during wet operation and dust during dry operation. A support member inserts into a receiving sleeve for a choice of wet or dry option. A squeegee system attached to the rear of the apparatus collects slurry and operates to send the slurry to a collection tank. The squeegee lifts out of the way during dry operation.
