Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing coupling processes for containers and components, such as capsule and filter, are complex, potentially dangerous, and require direct contact, leading to increased risk of damage to the product and components due to the need for multiple retaining elements and forced abutting.
Innovation Solution
A coupling method and unit that introduces a predetermined minimum spacing between the component and container, using a gripping device and coupling element to retain and move the component safely, allowing for a reproducible and stable coupling without direct contact, utilizing a frame with a gripping device and coupling device that maintain a safety spacing during movement and activation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If direct contact and forced abutting are used to couple component and container, then coupling stability is improved, but risk of damage to product and components increases
Solution Approach 1:
The patent introduces a coupling unit as an intermediary device that includes a gripping device and coupling element. This intermediary structure enables stable coupling between the component and container without requiring direct forced abutting, thereby reducing the risk of damage while maintaining coupling stability.
Solution Approach 2:
The patent implements a safety spacing mechanism that maintains a predetermined minimum distance between the component and container during the coupling process. This beforehand cushioning prevents direct contact and potential damage while ensuring stable coupling through the intermediary coupling unit.
2Reliability
If multiple retaining elements are used to secure component to container, then coupling reliability is improved, but device complexity increases
Solution Approach 1:
The patent merges the retaining element and coupling element into a single integrated coupling unit. This combining approach maintains coupling reliability by ensuring secure attachment while reducing device complexity by eliminating the need for multiple separate retaining elements.
3Manufacturing precision
If component is moved with direct constraint to achieve precise positioning, then manufacturing precision is improved, but loss of time increases
Solution Approach 1:
The patent employs a dynamic coupling process where the coupling unit can move freely within a safety spacing range before engaging the component. This dynamic approach allows for precise positioning to be achieved more quickly by reducing the time required for constrained movement and alignment.

AI summary
A coupling method for attaching a component to a container using an automated coupling unit. The method employs a coupling assembly mounted on a frame, having a gripping device with a retaining element for selectively holding the component, and a coupling device with an ultrasonic welder coupling element. The container is positioned in a retaining seat while the gripping device moves to contact and constrain the component. The retaining and coupling elements are then moved to a coupling position where a portion of the component contacts the container. The ultrasonic welder is activated for a time amount to create a stable coupling between the component and container. After deactivation, an ultrasonic pulse is generated to disengage the component from the coupling element before the elements move to a final position. The method enables automated attachment of components to containers through ultrasonic welding techniques.
