Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional methods for producing magnetic structures are used, then the production process is simple, but the ability to precisely tailor magnetic field characteristics is limited
Solution Approach 1:
The magnetic structure is divided into discrete magnetic pixels (maxels) that can be individually controlled. Each maxel represents a segmented unit of magnetization that can be independently activated or deactivated, enabling precise spatial control of magnetic field characteristics while using a relatively simple print head design with basic electromagnets arranged in a grid pattern.
Solution Approach 2:
The magnetic print head uses controllable electromagnets that can dynamically adjust their magnetic field strength and polarity by varying the current. This dynamic control allows the same apparatus to produce different magnetic field characteristics by changing electrical parameters rather than requiring complex mechanical adjustments or multiple fixed configurations.
2Adaptability or versatility
If magnetic print heads with multiple poles are used, then tailored magnetic field characteristics are achieved, but the device complexity increases
Solution Approach 1:
Different regions of the print head (different maxels) can be independently controlled to produce different magnetic properties. Each maxel can be activated or deactivated individually, allowing local customization of magnetic field characteristics across the printed surface without requiring the entire print head to be complex.
Solution Approach 2:
A single magnetic print head design with controllable electromagnets can perform multiple functions by varying the activation pattern of different maxels. The same apparatus can produce various magnetic field patterns, polarities, and intensities by selectively activating different combinations of electromagnets, eliminating the need for multiple specialized print heads.
3Ease of operation
If maxels are printed with both polarities exposed at the surface, then magnetic field control is simplified, but the magnetic structure lacks internal polarity configuration
Solution Approach 1:
The patent extends magnetic field control from two-dimensional surface patterns to three-dimensional internal structures by controlling which poles are exposed at the surface versus embedded within the material. This additional spatial dimension allows for complex internal magnetic configurations (such as hidden poles for magnetic shielding or specific field distributions) while maintaining relatively simple control through selective maxel activation patterns.
