Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the magnetic separator is fixed in position, then the structure is simple and stable, but the gap between the magnetic conveyor belt and main conveyor belt cannot be adjusted for different material thicknesses

Engineering Contradiction:
Improveadaptability to different material thicknessesVSAvoidmagnetic separator positioning structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The magnetic separator is designed with movable mounting that allows adjustment of its position relative to the main conveyor belt. The gap between the magnetic conveyor belt and main conveyor belt can be dynamically adjusted to accommodate different material thicknesses, transforming a static structure into a dynamic one that adapts to varying operational requirements.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The invention enables change of the gap parameter between the magnetic conveyor belt and main conveyor belt. By adjusting this physical parameter, the system can handle materials of different thicknesses effectively, allowing the magnetic separator to maintain optimal separation performance across varying material conditions.

Inventive Principle:
Principle #35Parameter changes

2Ease of operation

If the magnetic separator is fixed, then the structure is stable, but the main conveyor belt cannot be tilted into a compact configuration when not in use

Engineering Contradiction:
Improvecompact configuration capabilityVSAvoidmagnetic separator mounting structure
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The magnetic separator is mounted movably on the shredder frame, allowing it to move relative to the main conveyor belt. This dynamic mounting enables the main conveyor belt to be tilted into a compact configuration when not in use, while the magnetic separator can be repositioned to maintain the appropriate gap for separation operations.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The mounting structure is divided into independent components: the shredder frame, the main conveyor belt assembly, and the magnetic separator assembly. This segmentation allows the main conveyor belt to be tilted independently into a compact configuration while the magnetic separator remains positioned for operation, or vice versa.

Inventive Principle:
Principle #1Segmentation

3Adaptability or versatility

If the gap between magnetic conveyor belt and main conveyor belt is large, then thick material can be processed, but ferromagnetic material may be out of the field of attraction

Engineering Contradiction:
Improvehandling capability for different material thicknessesVSAvoidseparation efficiency
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The gap between the magnetic conveyor belt and main conveyor belt is made adjustable rather than fixed. This dynamic adjustment capability allows the system to optimize the gap size for each specific material thickness being processed, ensuring that ferromagnetic materials remain within the effective magnetic attraction field while accommodating variations in material thickness.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The invention enables dynamic change of the gap parameter based on the thickness of the material being processed. By adjusting this critical parameter, the system maintains optimal separation efficiency across different material conditions, ensuring ferromagnetic materials remain within the magnetic field's effective range.

Inventive Principle:
Principle #35Parameter changes
