Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If existing conveying systems are used for sheet conveying, then the conveying function is achieved, but the universality is poor and the cost is high

Engineering Contradiction:
ImproveuniversalityVSAvoidcost
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The press roller is divided into a main shaft and multiple detachable hollow rubber rollers. The hollow rubber rollers can be independently removed and replaced, allowing the system to adapt to different sheet specifications without replacing the entire press roller assembly, thereby improving universality while controlling cost.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The main shaft is designed to accommodate hollow rubber rollers with different outer diameters and widths. By changing the hollow rubber rollers, the same main shaft can serve multiple conveying functions for different sheet types, achieving multi-functionality and improved universality.

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

2Object-affected harmful factors

If existing conveying systems are used for sheet conveying, then the conveying function is achieved, but the sheets are likely to be damaged

Engineering Contradiction:
Improvesheet damageVSAvoidconveying quality
Core Design Contradiction:
Object-affected harmful factorsVSReliability

Solution Approach 1:

The hollow rubber rollers are made of rubber material with elastic properties, which can deform and adapt to the sheet surface. This changes the contact parameter from rigid to elastic, reducing stress concentration and preventing sheet damage while maintaining conveying reliability.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The press roller combines a metal main shaft with rubber hollow rollers, creating a composite structure. The rubber material provides elasticity and cushioning to protect the sheet, while the metal shaft provides structural strength, achieving both sheet protection and reliable conveying.

Inventive Principle:
Principle #40Composite materials

3Duration of action of stationary object

If existing conveying systems are used for sheet conveying, then the conveying function is achieved, but the maintenance cost is high and service life is limited

Engineering Contradiction:
Improveservice lifeVSAvoidmaintenance cost
Core Design Contradiction:
Duration of action of stationary objectVSEase of repair

Solution Approach 1:

The hollow rubber rollers are designed as detachable components that can be independently replaced when worn. This segmentation allows only the wear-prone rubber rollers to be replaced while the expensive main shaft is retained, reducing maintenance costs and extending the overall service life of the conveying system.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The hollow rubber rollers are designed as consumable parts that can be discarded when worn out, while the main shaft is recovered and reused. This approach reduces maintenance costs by replacing only the inexpensive rubber rollers rather than the entire press roller assembly, thereby extending the service life of the system.

Inventive Principle:
Principle #34Discarding and recovering

AI summary

The present application provides a conveying system and a battery production system. The conveying system is used for sheet conveying, and includes: a driving roller making contact with a sheet; and a press roller arranged correspondingly to the driving roller, the press roller abutting against at least part of the surface of the sheet facing away from the driving roller and pressing the sheet against the driving roller. The press roller includes: a main shaft with a central axis; at least one hollow rubber roller detachably sleeving the main shaft; and at least one pair of fixing clamp rings arranged on two sides of the hollow rubber roller along the central axis so as to fix the position of the hollow rubber roller on the main shaft along the central axis, where an outer diameter of the fixing clamp ring is less than that of the hollow rubber roller.
