Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If current solid state circuits use traditional components to hold binary state, then the circuit can store data, but the component count increases to eight or nine components
Solution Approach 1:
The patent combines multiple functions into a single magnetic induction circuit. The primary coil generates magnetic fields, the secondary coil detects them, and the circuit internally manages state retention through magnetic field coupling, eliminating the need for separate external switches and reducing component count from 8-9 to a compact integrated structure.
Solution Approach 2:
The magnetic induction circuit serves multiple functions: it acts as a switch, a memory element, and a data transmission medium simultaneously. The primary and secondary coils work together to both control and detect the magnetic field state, making the circuit universal and reducing overall system complexity.
2Ease of operation
If external switches are used to control magnetic field termination, then the magnetic field can be turned off, but the circuit requires external components and cannot internally manage state
Solution Approach 1:
The magnetic induction circuit is self-sufficient and does not require external switches. The secondary coil detects the magnetic field state and provides feedback that enables the circuit to internally control and terminate the magnetic field, making the system self-managing and eliminating external control components.
Solution Approach 2:
The secondary coil acts as a feedback mechanism that detects the magnetic field state generated by the primary coil. This feedback enables the circuit to internally regulate and terminate the magnetic field without external intervention, achieving self-controlled operation.
3Reliability
If traditional Flip Flop circuits are used to store binary data, then data retention is achieved, but the component count remains high at eight or nine components
Solution Approach 1:
The patent merges the functions of a Flip Flop circuit with magnetic induction into a single integrated structure. The interaction between primary and secondary coils creates bistable states that retain binary data, combining memory functionality with magnetic field control in one compact circuit instead of requiring multiple discrete components.

AI summary
The induction memory cell includes an electronic circuit that can control internally the “on” or “off” state of a magnetic field within a magnetic induction circuit. The induction memory cell can control external devices. When the induction memory cell is used in an array it can be programmed to retain binary information such as “on” as a binary digit of one or “off” as a binary digit of zero. The induction memory cell “on” or “off” state can be controlled via a one second burst of laser light, aim at one photo resistor for controlling the magnetic field “on” state in the primary coil or another photo resistor controlling the magnetic field “off” state in the primary coil. The induction memory cell requires a 1.5 volt, 5 amp power source in order to maintain an “on” or “off” switching effect in the primary coil.
