Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for an efficient apparatus and method to transfer pods from a storage tray to a machine cassette in a consumable unit manufacturing device, enabling quick succession of manufacturing steps on multiple pods.
Innovation Solution
The apparatus includes a transfer station with a cradle that rotates to invert the storage tray and machine cassette, allowing pods to be transferred from the storage tray to corresponding pockets in the machine cassette, and vice versa.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If pods are transferred manually from storage tray to machine cassette, then operation flexibility is maintained, but transfer speed and productivity are reduced
Solution Approach 1:
The transfer mechanism inverts the storage tray and machine cassette assembly, using gravity to automatically transfer pods from the tray to the cassette. This inverted transfer approach eliminates the need for complex mechanical pod handling mechanisms while maintaining high transfer speed.
Solution Approach 2:
The storage tray and machine cassette are combined into a single transferable assembly that can be moved together as one unit. This merging allows the entire pod transfer system to be relocated and inverted simultaneously, simplifying the transfer mechanism while improving productivity.
2Productivity
If multiple manufacturing steps are performed on pods in quick succession, then productivity is improved, but the need for rapid pod transfer between storage and processing increases
Solution Approach 1:
Pods are pre-arranged in the storage tray in the correct positions and orientations before transfer. The tray and cassette are pre-positioned relative to each other, so that when inverted, pods automatically transfer to the correct locations without requiring additional positioning adjustments during the manufacturing process.
Solution Approach 2:
The transfer mechanism enables continuous operation by allowing the tray-cassette assembly to be rapidly inverted and reset. While one assembly is being inverted for pod transfer, another can be prepared, ensuring that the manufacturing process experiences minimal interruption and maintains continuous productive action.
3Device complexity
If a simple transfer mechanism is used, then device complexity is reduced, but transfer precision and reliability may be compromised
Solution Approach 1:
The storage tray and machine cassette are designed with complementary geometries and positioning features that create a stable, repeatable relationship between them. When the assembly is inverted, the pods naturally settle into their correct positions due to the equipotential arrangement of the tray pockets and cassette receptacles, ensuring reliable and accurate transfer without complex positioning mechanisms.

AI summary
Apparatus for transferring pods, each of which form part of a consumable unit for use with an inhalation device, from a storage tray in which each pod is supported in a pod receiving pocket, to corresponding pod receiving pockets of a machine cassette forming part of a consumable unit manufacturing device, is disclosed. The apparatus comprises a transfer station to receive the tray and a machine cassette placed over the storage tray and the pods received in the storage tray. The transfer station is configured to rotate the combined tray and machine cassette so that the pods in the pod receiving pockets in the tray are transferred into corresponding pod receiving pockets in the machine cassette. A method for transferring pods the pod receiving pockets in the tray to corresponding pod receiving pockets in the machine cassette is also disclosed.
