Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Power

If a complex construction of various gear wheels is used for the drive, then the drive can be transmitted to the roller, but the device complexity increases and space usage increases

Engineering Contradiction:
Improvedrive transmission capabilityVSAvoidconstruction complexity
Core Design Contradiction:
PowerVSDevice complexity

Solution Approach 1:

The patent combines the drive wheel and the roller tube into a single integrated component. The drive wheel is formed as one piece with the roller tube, eliminating the need for separate gear wheels and complex transmission mechanisms. This merging reduces device complexity while maintaining the ability to transmit drive forces effectively to the roller.

Inventive Principle:
Principle #5Merging (Combining)

2Ease of manufacture

If separate ribbing is driven into the roller tube, then the roller tube can be assembled, but manufacturing precision decreases and production costs increase

Engineering Contradiction:
Improveassembly easeVSAvoidribbing coupling precision
Core Design Contradiction:
Ease of manufactureVSManufacturing precision

Solution Approach 1:

The ribbing is formed integrally with the roller tube in one piece during manufacturing. This eliminates the need for separate assembly of ribbing into the roller tube, ensuring precise coupling without requiring post-manufacturing assembly operations. The integral formation maintains manufacturing precision while simplifying the overall manufacturing process.

Inventive Principle:
Principle #5Merging (Combining)

3Ease of manufacture

If the ribbing has interruptions, then the roller tube can be manufactured more easily, but power transmission reliability decreases due to slippage

Engineering Contradiction:
Improveroller tube manufacturingVSAvoidpower transmission reliability
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The ribbing is designed to extend continuously or substantially continuously from one end of the roller tube to the other end. This continuous ribbing structure ensures reliable power transmission from the drive wheel to the roller tube without interruptions that could cause slippage. The continuous structure maintains transmission reliability while being manufacturable through integral forming processes.

Inventive Principle:
Principle #20Continuity of useful action

4Force

If a larger diameter sprocket is used, then the driving force per revolution increases, but the device complexity and space usage increase

Engineering Contradiction:
Improvedriving force per revolutionVSAvoidsprocket size complexity
Core Design Contradiction:
ForceVSDevice complexity

Solution Approach 1:

The sprocket is integrated into the roller tube as a one-piece construction. This merging allows the use of a larger diameter sprocket that provides greater driving force per revolution, while the integration into the roller tube structure avoids the complexity and space requirements of separate sprocket assemblies. The single-piece design achieves high force transmission without proportionally increasing device complexity.

Inventive Principle:
Principle #5Merging (Combining)
