Flat Panel Display Cleaning Roll Brush Mist Leakage Seal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaning apparatuses for flat panel displays leak internal mist outside, causing equipment corrosion and air pollution due to the need for openings that allow the roll brushes to move vertically, which mixes cleaning liquid with air and affects manufacturing processes and human safety.
Innovation Solution
The apparatus incorporates hollow cylindrical joint parts with larger inner diameters for liquid blocking members integrated with rotation shafts, and fans that generate air currents inward from the internal wall to prevent mist leakage, ensuring the mist does not escape through the gaps between the internal wall and roll brushes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If openings are provided in the internal wall to allow roll brushes to move vertically, then the cleaning apparatus can operate, but mist leaks outside causing equipment corrosion and air pollution
Solution Approach 1:
The patent employs a flexible curtain made of plastic strips that hangs from the internal wall to seal the opening. This flexible film structure allows the roll brushes to move vertically while preventing mist from leaking through the gap, thus resolving the contradiction between operational movement and mist containment.
2Adaptability or versatility
If openings are provided in the internal wall for rotation shafts and liquid blocking members, then the cleaning apparatus can function, but mist mixes with air and affects manufacturing processes
Solution Approach 1:
The flexible curtain composed of multiple plastic strips seals the opening in the internal wall, allowing the cleaning apparatus to maintain full functionality while preventing mist from escaping into the manufacturing environment. The curtain acts as a barrier that contains the mist within the cleaning chamber.
3Ease of operation
If the inner diameter of liquid blocking member is made larger than outer diameter of joint part, then roll brush can move vertically, but gap allows mist to leak
Solution Approach 1:
The flexible curtain made of plastic strips is installed to seal the gap between the liquid blocking member and the internal wall. This allows the roll brush to move vertically within the cleaning chamber while the curtain prevents mist from leaking through the necessary clearance gap.
