Innovation Solution
A device comprising a DC power source, inductors, a unilaterally conducting element, electrical load, and a buffer energy storage, where the inductor is connected to the power source's minus, and the buffer energy storage is connected to the electrical load, allowing for secondary current generation and magnetic field formation, thereby increasing efficiency and reducing energy consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a shunt diode is used to protect keys from self-induction EMF, then the key is protected from voltage spikes, but part of the self-induction EMF energy is released as heat on the diode and partially dissipates into the surrounding space
Solution Approach 1:
The patent converts the harmful self-induction EMF energy that would normally be dissipated as heat into a beneficial secondary current source. When the first key opens, the self-induction EMF generates a secondary current that flows through the second key and electrical load, performing useful work instead of being wasted as heat on a shunt diode.
Solution Approach 2:
The patent introduces a second key and electrical load as intermediary elements between the inductor and the ground. These intermediaries channel the self-induction EMF energy through a controlled path that performs useful work, rather than allowing direct dissipation through a simple shunt diode.
2Reliability
If self-induction EMF energy is dissipated through a shunt diode, then the circuit is protected from voltage spikes, but energy consumption increases and efficiency decreases
Solution Approach 1:
The patent transforms the previously wasted self-induction EMF energy into useful work by routing it through an electrical load. This conversion reduces the overall energy consumption from the power source while maintaining circuit protection, thereby improving efficiency.
3Ease of manufacture
If part of the self-induction EMF energy dissipates into the surrounding space, then the energy is lost, but the simple shunt diode design is easy to implement
Solution Approach 1:
The patent introduces additional intermediary components (second key, electrical load, buffer energy storage) that, while increasing design complexity, eliminate energy dissipation into the surrounding space by channeling the energy through productive pathways.

Implementation Method 2
a unilaterally conducting element, D1... the cathode of D1 is connected to the buffer energy storage, C
Implementation Method 3
a buffer energy storage, C, wherein the inductor L, by means of the key K1, is connected to the minus of the power source, while the buffer energy storage is connected to the minus of the power source
