Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If specific support elements are installed on the platform for each new automotive model, then the work parts can be positioned accurately, but the configuration process becomes complicated and costly

Engineering Contradiction:
Improvepositioning precisionVSAvoidconfiguration complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The patent applies universality by designing a single inclined plane structure that can accommodate multiple different work parts for various automotive models. Instead of installing specific support elements for each model, the inclined plane with its angular sector formed by two elements can universally position different work parts through gravity-driven sliding, eliminating the need for model-specific configurations while maintaining positioning accuracy

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

Solution Approach 2:

The work parts perform self-positioning by sliding down the inclined plane under gravity until they reach the angular sector formed by the two elements. This self-service mechanism eliminates the need for complex external positioning systems or manual adjustment of support elements, reducing configuration complexity while ensuring repeatable positioning for different work parts

Inventive Principle:
Principle #25Self-service

2Reliability

If specific support elements are installed on the platform for each new automotive model, then the work parts can be supported properly, but the configuration cost increases

Engineering Contradiction:
Improvesupport reliabilityVSAvoidconfiguration cost
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The inclined plane with two elements serves as a universal support structure that can accommodate different work parts for various automotive models without requiring model-specific support elements. This single versatile structure replaces multiple specialized components, reducing manufacturing and configuration costs while maintaining reliable support for diverse work parts

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

Solution Approach 2:

The patent employs simple, inexpensive materials such as bended sheet metal to create the two elements forming the angular sector. These simple components replace expensive, precision-machined support elements, achieving reliable work part support through gravity-driven positioning while significantly reducing the cost of platform configuration for new models

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

3Manufacturing precision

If precise positioning of work parts is required, then specific support elements must be installed, but the configuration process becomes time-consuming

Engineering Contradiction:
Improvepositioning accuracyVSAvoidconfiguration time
Core Design Contradiction:
Manufacturing precisionVSLoss of time

Solution Approach 1:

The work parts automatically position themselves by sliding down the inclined plane under gravity until they are constrained by the two elements forming the angular sector. This self-positioning mechanism eliminates the time-consuming process of manually installing and adjusting specific support elements for each work part, achieving precise and repeatable positioning instantly when the work part is placed on the inclined plane

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The inclined plane and two elements are pre-configured in a fixed position on the platform before any work parts are loaded. This preliminary setup creates a ready-to-use angular sector that will automatically position any work part placed within it, eliminating the need for time-consuming configuration adjustments when new work parts or models are introduced

Inventive Principle:
Principle #10Preliminary action
