Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual intervention is used to handle winding shafts with lifting beams, then flexibility in operation is maintained, but handling time increases and safety risks arise

Engineering Contradiction:
Improvemanual intervention capabilityVSAvoidhandling time
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The shaft positioning system performs alignment and positioning automatically through the interaction of sliding elements and guide arrangement, without requiring manual intervention. The system serves itself by using gravity and mechanical guidance to achieve precise positioning, eliminating the need for operators to manually attach ropes or hooks while reducing handling time

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent replaces the traditional manual lifting beam system with an automated mechanical positioning system using sliding elements and guide arrangements. This substitution transforms manual mechanical operations into an automated mechanical process that is both faster and safer

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Ease of operation

If manual handling procedures are used, then adaptability to different situations is maintained, but error probability increases

Engineering Contradiction:
Improveoperational flexibilityVSAvoiderror probability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The system automatically performs alignment and positioning through its mechanical design, eliminating human error. The sliding elements and guide arrangement work together to ensure precise shaft positioning without relying on operator skill or attention, thereby increasing reliability while maintaining operational flexibility

Inventive Principle:
Principle #25Self-service

3Object-affected harmful factors

If protective enclosures are opened for shaft handling, then safety of operators is ensured, but production cell downtime increases

Engineering Contradiction:
Improveoperator safetyVSAvoidproduction cell downtime
Core Design Contradiction:
Object-affected harmful factorsVSProductivity

Solution Approach 1:

The automated positioning system operates independently within the protective enclosure, allowing shaft handling to occur without opening the enclosure. The system's self-aligning mechanism works through the confined space, maintaining operator safety while preventing production downtime

Inventive Principle:
Principle #25Self-service

4Manufacturing precision

If precise shaft alignment is achieved through manual methods, then positioning accuracy is obtained, but handling complexity increases

Engineering Contradiction:
Improveshaft positioning accuracyVSAvoidhandling procedure complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The positioning system is divided into separate functional elements: sliding elements for movement and guide arrangement for positioning. This segmentation allows each component to perform its specific function simply, achieving precise alignment without complex overall procedures

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The guide arrangement acts as an intermediary between the sliding elements and the shaft, providing a standardized interface that simplifies the positioning process. This intermediary component enables precise alignment through a simple, repeatable mechanical interaction

Inventive Principle:
Principle #24Intermediary (Mediator)

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

Facilitates efficient, safe, and automated alignment and positioning of shafts, reducing manual intervention and downtime, enhancing safety and operational efficiency.

Implementation Method 1

The radial sliding element can have or consist of a roller. The roller provides a simple and cost-effective way to guide the load beam, for example, along a stop surface and/or groove of the guide assembly. The rolling motion of the roller enables guided relative movement along the guide assembly with low resistance.
