Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Force

If like poles of magnets are oriented to face each other, then magnetic repulsion force is generated, but the magnets cannot be brought into close proximity to maximize force

Engineering Contradiction:

Improvemagnetic repulsion forceVSAvoiddistance between magnets

Core Design Contradiction:

ForceVSLength of moving object

Solution Approach 1:

The patent divides the magnetic interaction into two distinct regions: a first region where like poles repel each other, and a second region where unlike poles attract each other. This segmentation allows the magnetic assembly to utilize both repulsive and attractive forces in different spatial zones, enabling the magnets to be positioned closer together while still achieving net repulsion through proper configuration of the magnetic components.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent combines multiple magnetic components (first magnet, second magnet, and third magnet) into a single integrated assembly where the magnetic fields interact in complex ways. By merging these components with specific permeance coefficient ratios, the system achieves enhanced repulsive force at close distances that would not be possible with simple pairwise magnet arrangements.

Inventive Principle:

Principle #5Merging (Combining)

2Adaptability or versatility

If unequally sized permanent magnet pairs are used, then unique magnetic behaviors are achieved, but device complexity increases

Engineering Contradiction:

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent systematically varies key parameters including the permeance coefficients of different magnets (Pc1, Pc2, Pc3), their relative sizes, and their spatial arrangements to achieve desired magnetic behaviors. By controlling these parameters, the system can produce consistent repulsive or attractive forces despite the complexity of having unequally sized magnets with different magnetic properties.

3Use of energy by moving object

If magnets are positioned close together to maximize force, then energy efficiency improves, but magnetic interference and instability increase

Engineering Contradiction:

Core Design Contradiction:

Solution Approach 1:

The third magnet serves as an intermediary component that mediates the magnetic interaction between the first and second magnets. Its specific permeance coefficient (Pc3) is designed to be greater than both Pc1 and Pc2, allowing it to control and stabilize the magnetic field in the region between the other two magnets, enabling close positioning while maintaining field stability.

AI summary

A vibrating magnetic assembly includes a housing, a first magnet positioned within the housing and having a first permeance coefficient (Pc1), a second magnet positioned within the housing and spaced from the first magnet, the second magnet having a second permeance coefficient (Pc2), and a third magnet positioned within the housing between the first and second magnets. The third magnet has a third permeance coefficient (Pc3) and is reciprocable between the first and second magnets to cause vibration. A ratio of Pc3:Pc1 and Pc3:Pc2 is greater than 1 such that the N pole of the third magnet is magnetically attracted to the N pole of the first magnet, and the S pole of the third magnet is magnetically attracted to the S pole of the second magnet when the third magnet is positioned within a threshold distance of the respective first or second magnet.
