Solution Overview
Problem
Existing dust-removing apparatuses for LCD panels and similar surfaces consume excessive energy due to high air flow rates, which is inefficient and increases operational costs.
Innovation Solution
A dust-removing apparatus with a cleaner head featuring an air reserve chamber and suction chamber, where the nozzle portion's design includes a jetting groove with specific cavity configurations to create a high-frequency air flow, allowing the dust-removed surface to be positioned within the transitional area of the jet's potential core, optimizing the slit width and parting dimension to reduce air flow while maintaining effective dust removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If air flow rate is increased to improve dust removal capability, then dust removal effect is improved, but energy consumption increases
Solution Approach 1:
The invention changes the parameters of the air jet system by optimizing nozzle geometry (slot width, length, shape) and operating conditions (pressure, flow rate) to achieve maximum dust removal efficiency at lower energy consumption. This involves systematic variation and optimization of multiple parameters simultaneously to find the optimal operating point.
Solution Approach 2:
The invention employs dynamic control of air flow rate and pressure to match the actual dust removal needs. The system can adjust air supply dynamically based on workpiece type, dust load, and cleaning requirements, avoiding continuous high-energy operation while maintaining effective dust removal performance.
2Loss of energy
If air flow rate is reduced to decrease energy consumption, then energy efficiency is improved, but dust removal capability deteriorates
Solution Approach 1:
The invention optimizes physical parameters of the nozzle system including slot width (0.5-5mm), slot length (10-100mm), and slot shape to maximize air jet effectiveness at reduced flow rates. The optimized geometry creates more efficient air distribution patterns that maintain dust removal capability while using less air and energy.
Solution Approach 2:
The invention replaces conventional high-flow mechanical air jet systems with an optimized slot nozzle system that achieves similar or better dust removal performance through improved fluid dynamics and air distribution, reducing reliance on high mechanical energy input.
3Manufacturing precision
If nozzle slot width is decreased to improve air flow distribution, then dust removal uniformity is improved, but manufacturing complexity increases
Solution Approach 1:
The invention establishes specific parameter ranges for nozzle slot dimensions (width: 0.5-5mm, length: 10-100mm) that balance manufacturing feasibility with performance optimization. These standardized ranges make the design practical for manufacturing while achieving improved dust removal uniformity across the workpiece surface.
Solution Approach 2:
The invention applies different slot configurations (width, length, shape) to different regions or applications based on specific dust removal requirements. This allows optimization of air flow distribution for uniform dust removal while adapting the design to manufacturing capabilities and specific workpiece geometries.
