Viscous Material Squeeze Nozzle for Bag Wrinkle Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional viscous material feed systems, such as those using inner bags and pressure plates, often result in wrinkles, leading to residual viscous materials remaining in the container, which can be problematic for sealing or adhesive applications.
Innovation Solution
A viscous material feed apparatus comprising a container with a bag body, a spout, and a nozzle, where the bag body is squeezed to move material toward the spout, and the nozzle is used to collect and deliver the material efficiently, reducing residual material by minimizing contact gaps and using a pump for efficient delivery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the inner bag is pressed by the pressure plate to apply viscous material, then the viscous material can be delivered to the sealing surface, but wrinkles are created in the bag body causing viscous material to remain in the container
Solution Approach 1:
The bag body is divided into multiple sections with different squeeze ratios. The first section has a larger cross-sectional area and is squeezed more strongly, while the second section has a smaller cross-sectional area and is squeezed less strongly. This segmentation allows different portions of the bag to be squeezed at different rates, preventing wrinkles and ensuring complete material delivery.
Solution Approach 2:
Different portions of the bag body are given different squeeze ratios based on their local characteristics. The first section (larger cross-sectional area) receives a larger squeeze ratio, while the second section (smaller cross-sectional area) receives a smaller squeeze ratio. This local differentiation optimizes material extraction from each section without creating wrinkles.
2Productivity
If the bag body is squeezed to move viscous material toward the spout, then material delivery is improved, but wrinkles are formed causing adhesive agent to enter and remain in the wrinkled bag
Solution Approach 1:
The bag body is segmented into multiple sections with different squeeze ratios to prevent wrinkle formation. The first section (larger cross-sectional area) is squeezed more strongly, while the second section (smaller cross-sectional area) is squeezed less strongly. This segmentation ensures smooth material flow without wrinkles that would trap adhesive agent.
Solution Approach 2:
The squeezing operation is performed in a controlled sequence where the first section is squeezed before the second section. This preliminary action ensures that material is moved toward the spout in the correct sequence, preventing wrinkles from forming and ensuring complete material delivery without adhesive agent remaining in the bag.
3Device complexity
If a simple squeezing mechanism is used to deliver viscous material, then the device complexity is reduced, but wrinkles are created leading to residual material in the container
Solution Approach 1:
The bag body is divided into multiple sections with different squeeze ratios. The first section has a larger cross-sectional area and is squeezed more strongly, while the second section has a smaller cross-sectional area and is squeezed less strongly. This segmentation can be achieved through a relatively simple squeezing mechanism that applies different forces to different sections, preventing wrinkles and ensuring complete material delivery.
Solution Approach 2:
Different portions of the bag body are given different squeeze ratios based on their local characteristics. The first section (larger cross-sectional area) receives a larger squeeze ratio, while the second section (smaller cross-sectional area) receives a smaller squeeze ratio. This local differentiation can be implemented through a simple squeezing mechanism that varies the applied force, optimizing material extraction without requiring complex device structures.
