Solution Overview
Problem
Conventional magnets in electronic devices and accessories are often pre-sized and pre-magnetized, limiting design flexibility and leading to inefficient use of space and material, as well as unwanted gaps and thickness issues due to their fixed shape and size.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If pre-sized and pre-constructed magnets are used, then magnetic function is achieved, but design flexibility is limited and material usage is inefficient
Solution Approach 1:
The patent changes the physical state parameter of magnetic material from pre-formed solid magnets to magnetizable powder or slurry that can be deposited and shaped. This allows the material to conform to any cavity shape while minimizing waste, as the magnetic properties are applied only where needed rather than using excess material in traditional magnet forms.
Solution Approach 2:
The patent replaces the mechanical system of pre-shaping magnets with molds and machining processes with a deposition-based system where magnetizable material is applied to cavities and then magnetized. This substitution enables complex shapes to be achieved through deposition rather than mechanical fabrication, improving both design flexibility and material efficiency.
2Reliability
If pre-shaped magnets are used, then magnetic function is provided, but gaps and thickness issues occur due to fixed shape and size
Solution Approach 1:
The patent applies local quality by depositing magnetizable material only in the specific cavity regions where magnetic function is required, rather than using uniform pre-shaped magnets. The material is applied locally to match the exact geometry of the cavity, eliminating gaps and achieving precise thickness control in each region.
Solution Approach 2:
The patent changes the shape parameter from fixed pre-formed magnets to variable shapes that conform to cavity geometry. By using deposition techniques, the magnetic material can be shaped to exactly match any cavity configuration, eliminating the gaps and thickness variations that occur with standard pre-shaped magnets.
3Adaptability or versatility
If conventional magnets are integrated, then magnetic functionality is achieved, but design and construction are limited by magnet size and structure
Solution Approach 1:
The patent merges the magnetic material application process with the device manufacturing process itself. By integrating the deposition and magnetization steps into the assembly line, the magnetic components are created and integrated in one continuous process rather than requiring separate magnet procurement and assembly steps, thereby reducing overall integration complexity.
Solution Approach 2:
The patent creates a universal deposition and magnetization system that can handle various cavity shapes, sizes, and configurations. This multi-functional approach allows the same equipment and process to produce different magnetic component geometries, expanding design options without proportionally increasing device complexity.
