Solution Overview

Problem

Existing devices for transporting flexible elements, such as those used in battery and fuel cell manufacturing, face challenges in achieving gentle and damage-free transport, particularly during the transition between continuous and discrete systems, and often result in longer cycle times.

Innovation Solution

A device comprising a transport unit with a guide plate and drive unit, where the guide plate has a non-circular geometry to adapt to varying distances and speeds, ensuring the transport unit remains in contact with the guide contour, and uses vacuum or suction to hold elements, allowing for precise positioning and reduced damage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional transport devices are used, then the flexible elements can be transported, but the transport causes damage and longer cycle times

Engineering Contradiction:
Improvedamage-free transportVSAvoidcycle time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The lifting device dynamically adjusts the distance between the drive shaft and transport device during rotation, allowing the transport unit to maintain optimal contact with the guide contour while accommodating varying distances at different positions. This dynamic adjustment enables gentle acceleration and deceleration of flexible elements, preventing damage while maintaining efficient cycle times.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system changes the positional parameter of the transport device relative to the drive shaft during rotation. By varying the distance between the drive shaft and transport device according to the guide contour geometry, the system optimizes the transport path to minimize damage while maintaining high-speed operation.

Inventive Principle:
Principle #35Parameter changes

2Measurement precision

If the transport unit is kept in constant contact with the guide contour, then positioning precision is improved, but the mechanism becomes more complex

Engineering Contradiction:
Improvepositioning accuracyVSAvoidmechanism complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The lifting device combines the functions of torque transmission and positional adjustment into a single integrated mechanism. By coupling the transport device to the drive shaft through this combined mechanism, the system achieves precise positioning along the guide contour without requiring separate control systems, thereby reducing overall complexity while maintaining high positioning accuracy.

Inventive Principle:
Principle #5Merging (Combining)

3Adaptability or versatility

If the drive shaft is positioned centrally, then the structure is simplified, but the transport unit cannot adapt to varying distances along the guide contour

Engineering Contradiction:
Improvedistance adaptationVSAvoidstructural complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The lifting device introduces dynamic adaptability by allowing the transport device to change its distance from the drive shaft during rotation. This dynamic adjustment mechanism enables the system to follow the non-circular guide contour while maintaining a simple central drive shaft structure, achieving adaptability without significantly increasing structural complexity.

Inventive Principle:
Principle #15Dynamics
