Elastic Nozzle Clamp Geometry for Adjustable Resin Ejection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing resin supply devices and molding apparatuses require frequent maintenance due to resin adhesion on components, and they lack the ability to efficiently adjust the amount of resin ejected per unit time without replacing parts.
Innovation Solution
A resin supply device with a nozzle made of an elastic material and a clamp mechanism that changes the ejection outlet's opening area into a symmetrical shape, allowing for adjustable resin ejection without adhesion and facilitating maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If flat plates or hollow ring-shaped members are used to change ejection outlet diameter, then the amount of resin material ejected per unit time can be adjusted, but the components require frequent washing and maintenance
Solution Approach 1:
The patent employs a clamp mechanism that dynamically adjusts the ejection outlet diameter by pressing the elastic nozzle from the outside. This allows continuous adjustment of resin ejection amount without requiring component replacement or washing, resolving the contradiction between adaptability and maintenance requirements.
Solution Approach 2:
The patent changes the physical state of the nozzle by applying external pressure through the clamp mechanism, which alters the ejection outlet diameter. This parameter change approach enables adjustment of resin ejection amount while avoiding the need to replace or wash the nozzle component.
2Adaptability or versatility
If the ejection outlet diameter is changed by pressing the elastic nozzle, then the amount of resin material ejected per unit time can be adjusted, but the nozzle requires frequent replacement
Solution Approach 1:
The clamp mechanism provides dynamic adjustment of the ejection outlet diameter without deforming or damaging the elastic nozzle. The nozzle maintains its original state after adjustment, eliminating the need for frequent replacement and improving reliability.
Solution Approach 2:
The elastic nozzle automatically returns to its original shape after the clamp pressure is released, making it self-restoring. This self-service capability eliminates the need for frequent nozzle replacement and maintains consistent performance.
3Manufacturing precision
If the ejection outlet is shaped with three or more fold rotational symmetry, then the resin ejection accuracy is improved, but the device complexity increases
Solution Approach 1:
The clamp mechanism employs symmetric arrangement of clamp members around the nozzle to create three or more fold rotational symmetry in the ejection outlet shape. This asymmetric-to-symmetric transformation achieves high ejection accuracy while keeping the mechanism itself symmetric and simple.
Solution Approach 2:
The patent utilizes the circular symmetry of the nozzle cross-section and applies uniform pressure at multiple points to maintain rotational symmetry in the ejection outlet. This approach achieves precise ejection while avoiding complex geometric structures.
