Solution Overview

Problem

Existing devices for transferring articles like syringes are prone to damage due to imperfect coupling caused by dimensional tolerances, leading to potential breakage during loading and unloading, especially when dealing with fragile and poorly-deformable materials.

Innovation Solution

A transfer carousel with elastically deformable appendages and an oscillating tooth mechanism that absorbs stress during imperfect coupling, allowing for flexible adaptation to articles of varying sizes and preventing damage by locking and releasing articles securely during transport.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a rigid shaped seating is used on the transfer carousel to securely hold articles, then the article retention is improved, but the risk of damage to fragile articles with dimensional tolerances increases

Engineering Contradiction:
Improvearticle retentionVSAvoiddamage risk
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The seating is designed with elastic deformability, allowing it to change its physical state from rigid to flexible during operation. This enables the seating to adapt its shape and dimensions to accommodate articles with manufacturing tolerances while maintaining secure retention, thereby reducing damage risk without sacrificing reliability

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The seating transitions from a static rigid structure to a dynamic elastic structure that can deform and recover. This dynamic behavior allows the seating to absorb dimensional variations of articles during loading and unloading phases, preventing damage while ensuring reliable retention throughout the transport cycle

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If the seating is made elastic to accommodate dimensional variations, then the adaptability to articles of varying sizes is improved, but the structural complexity increases

Engineering Contradiction:
Improvesize accommodationVSAvoidseating structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The seating is implemented as an elastic element or flexible structure that can deform to accommodate articles of varying sizes. This flexible shell approach provides adaptability without requiring complex adjustable mechanisms, maintaining structural simplicity while achieving the desired versatility

Inventive Principle:
Principle #30Flexible shells and thin films

Solution Approach 2:

The elastic seating serves multiple functions: it provides article retention, accommodates dimensional variations, and absorbs shock during loading/unloading. This multi-functionality is achieved through a single elastic component rather than multiple specialized mechanisms, thereby avoiding increased structural complexity

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

A device for receiving and transporting articles, in particular syringes and the like, of a type comprising a transfer carousel (2) destined to be rotated about a substantially vertical axis (3) peripherally bearing a series of seatings (6) for receiving single articles (5) from a supply station (10) and for transferring the articles (5) to a receiving station (20). The seatings (6) are fashioned from respective shaped and recessed surfaces realised on respective appendages (4) peripherally associated to the carousel (2) and elastically deformable such as to absorb any variations in size of the articles (5).
