Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If coil windings are used to generate magnetic fields, then magnetic field generation is achieved, but the device becomes inefficient and limited in generating strong magnetic fields
Solution Approach 1:
The patent removes the coil windings from the electromagnetic data storage device, extracting the inefficient magnetic field generation method. Instead of using traditional coil windings that require multiple turns and generate weak magnetic fields, the invention directly uses permanent magnets to provide the magnetic field, eliminating the problematic component while maintaining the essential function.
Solution Approach 2:
The invention changes the fundamental parameter of magnetic field generation from electromagnetic induction (requiring current through coils) to direct magnetic field provision by permanent magnets. This parameter change enables strong magnetic fields without the limitations of coil windings, improving both power efficiency and productivity in data storage operations.
2Strength
If coil windings are used, then magnetic field generation is possible, but the device complexity increases and strong magnetic fields are limited
Solution Approach 1:
The patent extracts and removes the coil winding structure from the device, eliminating the complex multi-turn wire arrangements. By replacing coils with permanent magnets, the invention simplifies the device structure while achieving stronger and more reliable magnetic fields without the mechanical complexity of wound coils.
Solution Approach 2:
The invention employs composite material structures combining permanent magnets with conductor arrays and integrated circuits. This composite approach replaces the homogeneous coil winding structure with a multi-component system that achieves superior magnetic field strength while reducing overall device complexity through functional integration.
3Reliability
If traditional coil windings are used, then electromagnetic operation is achieved, but energy efficiency is reduced
Solution Approach 1:
The permanent magnets in the invention provide magnetic fields without requiring external energy input for field generation. The magnets self-generate the necessary magnetic flux, eliminating energy losses associated with resistive heating in coil windings. This self-service approach improves energy efficiency while maintaining reliable data storage through the integrated conductor and control circuit system.
