Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing apparatuses for preparing capsules with frustum-like bags suffer from imperfect shape formation, leading to issues in heat-sealing and quality control, requiring complex and difficult-to-maintain devices for bag placement, resulting in poor product quality and machine downtime.
Innovation Solution
A calibrated coupling station with a grip element and lower retention member, allowing precise positioning and heat-sealing of the bag within the container, eliminating the need for complex devices and ensuring consistent quality by maintaining a predefined distance between the bag's bottom and the container's base.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If complex devices are used for placing the bag inside the container, then the positioning precision of the bag bottom is improved, but the device complexity increases and maintenance difficulty increases
Solution Approach 1:
The device is divided into two independent retention members: a first retention member for retaining the bag and a second retention member for retaining the container. This segmentation allows each member to be simple in structure while achieving precise positioning through their coordinated interaction. The first retention member has a first end for bag engagement and a second end for positioning, while the second retention member has a first end for container engagement and a second end for positioning, creating a modular system that is both precise and maintainable.
2Manufacturing precision
If complex devices are used for placing the bag inside the container, then the positioning precision is improved, but the ease of repair deteriorates
Solution Approach 1:
By segmenting the retention system into two separate, independent retention members with clearly defined functions, the design enables easy maintenance. Each retention member can be individually inspected, cleaned, and replaced without affecting the other component, significantly improving ease of repair compared to integrated complex mechanisms.
Solution Approach 2:
The invention extracts the positioning function from a complex integrated device and implements it through the simple geometric relationship between the second end of the first retention member and the second end of the second retention member. This extraction of the positioning function into a separate, simple mechanism makes the overall system easier to maintain while preserving positioning precision.
3Productivity
If the bag shape formation is imperfect, then the production speed is maintained, but the quality of capsules deteriorates and machine downtime increases
Solution Approach 1:
The invention performs preliminary positioning action by using the first and second retention members to establish the correct spatial relationship between the bag and container bottom before the heat-sealing operation begins. This preliminary positioning ensures that even if bag shape formation varies, the critical positioning parameters are correct, preventing quality defects and rework that would cause downtime.
Solution Approach 2:
The invention replaces complex mechanical bag shaping and positioning mechanisms with a simpler retention system that uses the geometric relationship between retention member ends to define positions. This substitution maintains productivity while improving quality by focusing on the critical positioning function rather than attempting to control bag shape formation mechanically.
4Device complexity
If the distance between bag bottom and container base is not precisely controlled, then the device complexity is reduced, but the quality consistency of capsules deteriorates
Solution Approach 1:
The invention introduces the second end of the first retention member as an intermediary element that mediates the positioning between the bag (retained by first end) and the container (retained by second end of second retention member). This intermediary creates a reliable geometric reference that ensures precise distance control while keeping the overall device simple in structure.

AI summary
A calibrated coupling station for components of capsules includes an external body and a bag. A through seat for stably housing the external body supports the bag and is arranged on an articulated sector of a respective advancement component movable along a frame. At least one grip element is aligned with a predefined stop area of the at least one through seat and is movable from a raised configuration in which its terminal end rests on a bottom of the bag, in turn juxtaposed against an inner face of the base of the external body/The grip element is adapted to define an intermediate configuration for a calibrated positioning in which the terminal end, stably coupled to the bottom of the bag, is arranged at a predefined distance from the inner face of the base of the external body.
