Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If shuttles are returned in a cyclic manner using traditional conveying systems, then reliability of shuttle return is improved, but floor space consumption increases which is problematic in clean room environments

Engineering Contradiction:
Improveshuttle return reliabilityVSAvoidfloor space consumption
Core Design Contradiction:
ReliabilityVSArea of stationary object

Solution Approach 1:

The conveying system transitions from a traditional horizontal floor-based layout to a vertical three-dimensional configuration. Shuttles are conveyed horizontally along the assembly line, then returned vertically above or below the assembly line using overhead conveying modules. This dimensional change allows the return path to occupy vertical space rather than additional floor space, resolving the contradiction between reliable cyclic shuttle return and minimal floor space consumption in clean room environments.

2Device complexity

If traditional conveying systems are used for shuttle return, then system simplicity is maintained, but flexibility for different assembly system configurations is reduced

Engineering Contradiction:
Improvesystem simplicityVSAvoidconfiguration flexibility
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The conveying system is divided into functionally independent modules: assembly line conveying modules that move shuttles horizontally through assembly stations, and overhead return conveying modules that transport shuttles back to the start. These modular units can be independently configured, positioned, and controlled, enabling flexible adaptation to different assembly system layouts and requirements while maintaining operational simplicity through standardized module design.

3Productivity

If shuttles are conveyed along a linear path, then conveying efficiency is improved, but space utilization in limited clean room environments deteriorates

Engineering Contradiction:
Improveconveying efficiencyVSAvoidclean room floor space
Core Design Contradiction:
ProductivityVSArea of stationary object

Solution Approach 1:

The system maintains efficient linear horizontal conveying for assembly operations while introducing a vertical dimension for the return path. Overhead conveying modules operate in the vertical space above or below the assembly line, allowing shuttles to be returned without occupying additional horizontal floor space. This preserves conveying efficiency while optimizing space utilization in constrained clean room environments.

AI summary

Disclosed is a conveying system with a conveying line (1 ) and a number of shuttles (3). The conveying line (1 ) includes a number of conveying modules (11, 12, 13), wherein each conveying module (11, 12, 13) includes a c conveying belt (111), the conveying belt generally extending in parallel with a longitudinal conveying line axis (1c). The conveying belt (111) includes a counter-magnetic member that substantially along the whole circumference of the conveying belt (111). Each shuttle (3) includes a product interface for operatively coupling with a product to be conveyed and a magnetic member (32). Each shuttle (3) and each conveying module (11, 12, 13) may be temporarily associated with each other to establish a shuttle conveying module combination. In a shuttle conveying module combination, the magnetic member (32) of the shuttle (3) and the counter- magnetic member (1112) of the conveying belt (111 ) of the conveying module (11, 12, 13) interact byway of ferromagnetic forces, thereby releasably coupling the shuttle (3) to the conveying belt (111) of the conveying module (11, 12, 13).
