Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing resin sheet manufacturing methods struggle with inconsistent quality due to inaccuracies in positioning and angling of air nozzles, leading to phenomena such as resonance, neck-in, and unevenness.
Innovation Solution
An air nozzle device with a movable and rotatable air nozzle body, controlled by a drive mechanism and a control unit, allows precise adjustment of position and angle to stabilize the air flow, preventing or suppressing these phenomena.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the air nozzle position and angle are fixed, then the device structure is simple, but the resin sheet quality cannot be uniformly adjusted
Solution Approach 1:
The air nozzle is made movable through a drive mechanism that enables adjustment in multiple directions (upward/downward, leftward/rightward, forward/backward) and rotation. This dynamic capability allows the nozzle position and angle to be adjusted to different locations, achieving uniform resin sheet quality while maintaining a relatively simple device structure through controlled mobility rather than fixed complexity.
2Measurement precision
If the air nozzle is made movable and rotatable, then the position and angle can be accurately adjusted, but the device complexity increases
Solution Approach 1:
The drive mechanism provides controlled mobility to the air nozzle, enabling accurate adjustment in multiple directions and rotation. The control unit coordinates these movements to achieve precise positioning and angling, demonstrating that controlled dynamic adjustment can provide measurement precision without excessive device complexity.
Solution Approach 2:
The control unit manages the drive mechanism to adjust the air nozzle position and angle, implying a feedback control system that monitors and corrects positioning accuracy. This feedback approach enables precise adjustment while keeping the overall device complexity manageable through intelligent control rather than purely mechanical complexity.
3Reliability
If the air nozzle position is not accurately adjusted, then the device operation is simple, but resonance and neck-in phenomena occur
Solution Approach 1:
The control unit coordinates the drive mechanism to adjust the air nozzle position and angle, implying a feedback control system that monitors and corrects positioning accuracy. This feedback approach enables precise adjustment while keeping the overall device complexity manageable through intelligent control rather than purely mechanical complexity.
Solution Approach 2:
The system automatically adjusts the air nozzle position and angle through the drive mechanism and control unit, reducing manual intervention. The apparatus self-regulates the nozzle positioning to prevent resonance and neck-in phenomena, improving manufacturing stability while simplifying operation through automation.
