Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Power

If electromagnets are configured in a Halbach array sequence with substantially contiguous cores, then the Halbach effect is maximized and magnetic flux transmission is enhanced, but the device complexity increases due to the need for precise core contiguity and magnetic flux conduits

Engineering Contradiction:

Improvemagnetic flux transmissionVSAvoidcore configuration complexity

Core Design Contradiction:

PowerVSDevice complexity

Solution Approach 1:

Adjacent electromagnetic cores are merged into a substantially contiguous structure, eliminating air gaps and magnetic flux interruptions. The cores are physically connected to form a continuous magnetic path, enabling the Halbach array to function as intended with enhanced magnetic flux transmission.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

Magnetic flux conduits are introduced as intermediary structures that bridge adjacent electromagnetic cores. These conduits provide dedicated pathways for magnetic flux to flow continuously between cores, ensuring the Halbach effect is properly harnessed while managing the complexity of core integration.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of manufacture

If electromagnets are spaced far apart in the array, then the device structure is simpler and easier to manufacture, but the Halbach effect is weakened and magnetic forces are reduced

Engineering Contradiction:

Improveelectromagnet spacingVSAvoidmagnetic force

Core Design Contradiction:

Ease of manufactureVSForce

Solution Approach 1:

Instead of spacing electromagnets apart, the invention merges adjacent electromagnet cores into a contiguous structure. This eliminates the need for precise spacing while ensuring strong magnetic coupling and maximizing the Halbach effect, thereby maintaining ease of manufacture without sacrificing magnetic force.

Inventive Principle:

Principle #5Merging (Combining)

3Ease of operation

If electromagnetic cores are physically separated, then the device assembly is easier and more flexible, but the Halbach effect is substantially negated and efficiency is reduced

Engineering Contradiction:

Improveassembly flexibilityVSAvoidenergy efficiency

Core Design Contradiction:

Ease of operationVSUse of energy by moving object

Solution Approach 1:

The electromagnetic cores are merged into a substantially contiguous structure that is pre-assembled as an integrated unit. This maintains assembly flexibility at the module level while ensuring internal contiguity for optimal Halbach effect and energy efficiency.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The electromagnetic cores are pre-configured in a substantially contiguous arrangement during manufacturing, establishing the proper magnetic flux pathways before the device is assembled. This preliminary action ensures the Halbach effect is optimized without complicating the final assembly process.

Inventive Principle:
