Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing floor treatment apparatuses generate dust during grinding, sanding, and polishing processes, which poses health risks, damages equipment, and leads to sludge formation, requiring an improved solution to reduce dust dispersion and facilitate efficient cleaning.
Innovation Solution
A floor treatment apparatus with a housing and drive system featuring a transmission shaft, motor, and rotatable drive plate, equipped with an open-ended tubular casing for central dust removal and optional fluid conduit, along with a quick release mechanism for coupling members, allowing for adaptable treatment configurations and reduced dust collection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If fluid is provided during grinding process, then dust formation is reduced, but sludge formation increases which is difficult to remove
Solution Approach 1:
The patent extracts the harmful sludge from the system by providing a separate collection container (dust container) that is detachably connected to the housing. This allows the sludge and dust mixture to be removed easily from the apparatus without disassembling internal components, directly addressing the problem of difficult sludge removal while maintaining the dust-reducing fluid application benefit
2Device complexity
If treatment members are directly connected to drive plate, then structural simplicity is maintained, but dust accumulates on apparatus parts leading to reduced operational uptime
Solution Approach 1:
The patent segments the connection between the drive plate and treatment members by introducing a coupling member as an intermediate detachable component. This allows the treatment member to be easily removed and replaced without affecting the drive plate or motor, facilitating quick maintenance and reducing operational downtime while keeping the overall structure relatively simple
3Stability of the object's composition
If coupling members are permanently attached to drive plate, then structural stability is improved, but adaptability for different treatment configurations is reduced
Solution Approach 1:
The patent implements a dynamic connection system where the coupling member can be detachably attached to the drive plate through a quick release mechanism. This allows the system to transition between stable operation (when coupled) and flexible reconfiguration (when decoupled), enabling different treatment configurations while maintaining structural stability during operation
4Device complexity
If dust is allowed to disperse during grinding, then no additional dust collection system is needed, but health risks and equipment damage increase
Solution Approach 1:
The patent introduces a fluid conduit as an intermediary element that delivers fluid to the treatment area during grinding. This intermediary system effectively reduces dust formation and dispersal, protecting against health risks and equipment damage while adding only a relatively simple fluid delivery mechanism to the overall system
