Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Floor grinding machines for stone or stone-like materials face difficulties in cleaning accumulated residues, which affect efficiency and balance, and can be damaged during the cleaning process.
Innovation Solution
Incorporation of a resilient, hollow member within the grinding head hood that expands with pressurized fluid to easily release and remove residues without disassembly, utilizing a pressurized fluid source connected to the member to facilitate cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional cleaning methods (hammer and chisel) are used to remove accumulated residues, then residues can be removed, but the machine structure may be damaged
Solution Approach 1:
The patent replaces the mechanical cleaning system (hammer and chisel) with a pneumatic system. A hollow member positioned inside the hood receives pressurized fluid (air or water) that directs a jet stream onto accumulated residues, causing them to detach and be removed through apertures in the hood. This substitution eliminates the need for manual mechanical cleaning that risks damaging the machine structure.
Solution Approach 2:
The patent introduces a hollow member as an intermediary device between the pressurized fluid source and the residues. This hollow member positions and directs the fluid jet precisely onto the residues, enabling effective removal while protecting the machine structure from direct contact with cleaning tools.
2Reliability
If residues are allowed to accumulate on the grinding head hood, then the machine structure is preserved, but grinding efficiency decreases and heat dissipation is impaired
Solution Approach 1:
The patent implements preliminary action by continuously or periodically removing residues before they can significantly accumulate and impair machine performance. The pneumatic cleaning system is activated to jet residues off the grinding head hood, preventing the formation of large residue blocks that would block apertures and reduce grinding efficiency or heat dissipation.
3Ease of operation
If the hollow member is made expandable, then it can effectively release accumulated residues, but the device complexity increases
Solution Approach 1:
The patent applies pneumatics and hydraulics by using a hollow member with apertures that receives pressurized fluid (air or water). The pressurized fluid is directed through the hollow member onto accumulated residues, utilizing fluid pressure to detach and remove residues effectively without requiring the hollow member itself to be expandable or mechanically complex.
