Solution Overview

Problem

Conventional sample-conveying systems with belt-conveyor mechanisms often require frequent movement of mobile units between conveying paths, posing safety risks and obstructing operator or vehicle passages.

Innovation Solution

A sample-conveying system with a belt-conveyor type mechanism featuring first and second conveying paths separated by transition bases, where a mobile unit is guided by a cranked guide member, and carriers transfer receptacles between paths, reducing the frequency of mobile unit movement and enhancing passage safety by allowing longer utilization as a passage for operators or vehicles.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the mobile unit frequently moves between the first and second conveying paths to feed many holders, then the productivity of sample conveyance is improved, but the safety of the passage for operators or work vehicles deteriorates

Engineering Contradiction:

Improvesample conveyance throughputVSAvoidsafety risk to operators or work vehicles

Core Design Contradiction:

ProductivityVSObject-affected harmful factors

Solution Approach 1:

The system divides the sample conveyance function into two parts: the mobile unit handles rack transportation between conveying paths, while separate receptacle carriers handle the actual sample transfer operations at each path. This segmentation allows the mobile unit to operate less frequently while maintaining high productivity.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The receptacle carriers are positioned in advance at both the first and second conveying paths, ready to perform sample transfer operations. This preliminary positioning eliminates the need for the mobile unit to make frequent stops for sample transfer, reducing its movement frequency and improving passage safety.

Inventive Principle:

Principle #10Preliminary action

2Adaptability or versatility

If long conveying paths are arranged throughout the installation space to convey samples over long distances, then the adaptability of the system is improved, but the obstruction of passages for operators or work vehicles worsens

Engineering Contradiction:

Improveconveyance path coverageVSAvoidpassage accessibility

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The system uses a mobile unit that moves vertically between conveying paths rather than extending conveying paths horizontally throughout the installation space. This dimensional change allows comprehensive sample conveyance coverage while maintaining open horizontal passages for operators and work vehicles.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

AI summary

A sample-conveying system has first and second conveying paths which are separated from each other. A first transition base is located at a conveyance terminal end portion of the conveying path. A second transition base is located at a conveyance starting end portion of the conveying path. A mobile unit moves between the first and second conveying paths. The transition base is provided with a receptacle carrier and a rack carrier. The receptacle carrier transfers receptacles on the conveying path to a rack on the transition base. The rack carrier transfers the rack on the transition base onto the mobile unit. The transition base is provided with a rack carrier and a receptacle carrier. The second rack carrier transfers the rack on the mobile unit onto the transition base. The second receptacle carrier transfers each receptacle held in the rack to a holder in the conveying path.
