Solution Overview

Problem

Conventional conveyance systems for containers risk damaging the containers due to contact with guides during inspection, leading to scratches or other forms of damage.

Innovation Solution

A conveyance system featuring a disc-shaped rotor with a table and a puck mechanism that includes a first puck member, a second puck member, and a pusher member, allowing for vertical movement and rotation to prevent contact with guides, while also incorporating a cap for stable holding and imaging capabilities.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If conventional conveyance systems use guides to direct containers, then conveyance function is achieved, but container damage occurs due to contact with guides

Engineering Contradiction:
Improveconveyance functionVSAvoidcontainer damage
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The invention removes the guide component entirely from the conveyance system. Instead of using guides to direct containers, the system employs a rotor with multiple stations where containers are held and transferred without contact with guiding surfaces, thereby eliminating the source of damage while maintaining conveyance functionality

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The invention introduces intermediate holding stations on the rotor between the supply section and inspection section. These stations act as mediators that receive containers from the supply section and transfer them to the inspection section without requiring direct contact with guides, thus preventing damage during transfer

Inventive Principle:
Principle #24Intermediary (Mediator)

2Manufacturing precision

If containers are conveyed through contact with guides, then positioning accuracy is achieved, but scratches and damage occur on container surfaces

Engineering Contradiction:
Improvepositioning accuracyVSAvoidsurface scratches
Core Design Contradiction:
Manufacturing precisionVSObject-affected harmful factors

Solution Approach 1:

The invention replaces the mechanical guide-contact positioning system with a rotational positioning system. The rotor rotates to precisely position containers at different stations (supply, inspection, discharge) without mechanical contact, maintaining positioning accuracy while eliminating surface damage from guide contact

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The invention transitions from two-dimensional guide-based positioning to three-dimensional rotational positioning. Containers are positioned not only along the conveyance path but also through vertical movement between different rotor levels, enabling precise positioning without guide contact

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Object-affected harmful factors

If a complex guide system is used to prevent container damage, then protection is improved, but device complexity increases

Engineering Contradiction:
Improvecontainer protectionVSAvoidsystem complexity
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The invention employs a dynamic rotor system that rotates to bring containers to different functional stations. This dynamic approach allows the same structure to serve multiple functions (conveyance, positioning, protection) without requiring complex static guide systems, reducing overall system complexity while maintaining protection

Inventive Principle:
Principle #15Dynamics
