Spout Holding Device Elastic Force Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional spout handling methods, such as pinching with pinching members, are ineffective for spout parts without a mouth part and can cause deformation or damage due to uneven force distribution, especially when the spout part has a special shape or insufficient rigidity.
Innovation Solution
A spout supply mechanism with a spout holding device that uses an elastic part capable of deforming in multiple directions to apply elastic force to the spout part in three or more directions, preventing deformation and damage by distributing force evenly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If pinching members are used to hold the spout part, then the spout part can be transferred, but the spout part may be deformed or damaged due to uneven force distribution
Solution Approach 1:
The holding force is segmented into multiple application points around the spout part. Instead of concentrating force at a single pinching point, the elastic part distributes holding force through multiple contact points along the inner circumference of the spout, preventing localized deformation while maintaining secure transfer capability.
Solution Approach 2:
The elastic part provides locally adaptive holding quality by deforming to match the specific geometry of the spout part being held. This allows the holding mechanism to adapt to different spout shapes (including special shapes without mouth parts) and apply force evenly across the contact surface, preventing damage while ensuring secure transfer.
2Productivity
If pinching members are used to hold the spout part, then transfer can be performed, but the method is ineffective for spout parts without a mouth part or with special shapes
Solution Approach 1:
The elastic part serves as a universal holding mechanism that can accommodate various spout part configurations. By using the inner circumference of the spout part itself as the contact surface rather than requiring specific external features like mouth parts, the mechanism achieves multi-functionality across different spout designs while maintaining efficient transfer capability.
Solution Approach 2:
Instead of holding the spout part from the outside (as with conventional pinching members), the elastic part holds the spout part from the inside by inserting into the spout and contacting the inner circumference. This inverted approach eliminates the need for external pinching surfaces and enables handling of spout parts with special shapes that lack conventional gripping features.
3Adaptability or versatility
If elastic part is inserted into communication hole to hold spout part, then various shapes can be accommodated, but device complexity increases
Solution Approach 1:
The elastic part utilizes the spout part's own structure (its inner circumference) as the holding surface. The spout part effectively serves itself by providing the contact surface needed for holding, eliminating the need for complex external gripping mechanisms and reducing overall device complexity while maintaining versatility.
