Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If a conveying unit conveys raw material containing various part scraps with different shapes and specific gravities, then the conveying capacity is improved, but the dropping position control deteriorates due to changed falling trajectories

Engineering Contradiction:

Improveconveying capacityVSAvoiddropping position control

Core Design Contradiction:

Quantity of substanceVSManufacturing precision

Solution Approach 1:

The conveying unit is divided into multiple independent conveying sections, each capable of controlling the dropping position of raw materials. This segmentation allows different sections to handle materials with varying shapes and specific gravities independently, maintaining dropping position control while conveying diverse materials.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The invention introduces a vertical dimension to the conveying system by adjusting the conveying path height and using vertical conveying sections. This dimensional change enables control over the falling trajectory of raw materials, allowing precise dropping position control even for materials with different shapes and specific gravities.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Length of moving object

If the conveying path is extended to convey raw materials over a longer distance, then the conveying range is improved, but the dropping position control deteriorates due to aggregation of part scraps

Engineering Contradiction:

Improveconveying rangeVSAvoiddropping position control

Core Design Contradiction:

Length of moving objectVSManufacturing precision

Solution Approach 1:

The conveying unit employs periodic vibration or movement along the conveying path to prevent aggregation of part scraps during extended conveying. This periodic action keeps materials dispersed throughout the conveying path, maintaining dropping position control even over long conveying distances.

Inventive Principle:

Principle #19Periodic action

Solution Approach 2:

The invention replaces traditional mechanical conveying mechanisms with a system that uses controlled vibration or airflow to move raw materials. This substitution prevents material aggregation during extended conveying while maintaining precise dropping position control through controlled release mechanisms.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)
