Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If conventional battery saving mode techniques are used, then battery life is prolonged when load demands less power, but battery life cannot be prolonged when load continuously demands power
Solution Approach 1:
The patent applies electrical resonance (analogous to mechanical vibration) by connecting a charge storage device to form a modified tank circuit with the battery. By supplying voltage at the resonant frequency, internal resonance occurs within the battery, causing chemical reactions that release free electrons for additional power extraction. This resolves the contradiction by enabling battery life extension specifically under continuous load conditions through resonant frequency excitation.
Solution Approach 2:
The controller supplies voltage to the battery in periodic pulses at the resonant frequency rather than continuous voltage. This periodic excitation at specific intervals allows the battery to undergo resonant chemical reactions that release additional electrons, enabling power extraction beyond conventional limits while maintaining battery life under continuous load conditions.
2Duration of action of moving object
If additional power is extracted from battery through resonance, then battery life is prolonged and load demands are met, but system complexity increases due to charge storage device and controller
Solution Approach 1:
The charge storage device serves multiple functions: it forms part of the resonant tank circuit to enable internal battery resonance, stores energy during charging phases, and supplies voltage pulses at resonant frequency. The controller simultaneously computes resonant frequency, generates timing signals, and manages the charging/discharging cycles. This multi-functionality reduces the need for separate dedicated components for each function.
Solution Approach 2:
The battery itself provides the inductive reactance component of the tank circuit, using its own internal properties rather than requiring an external inductor. The charge storage device and controller work together to exploit the battery's inherent electrical characteristics to create the resonant circuit, reducing the need for additional passive components and simplifying the overall system structure.

Function Achieved in This Case
The system prolongs battery life and provides additional power as needed by using the extracted electrons to charge the charge storage device, which in turn recharges the battery, thereby increasing its discharge time and power supply capacity.
Implementation Method 1
when the battery of the modified tank circuit is supplied with a specific voltage at a specific time, an internal resonance within the battery and the charge storage device may occur
Implementation Method 2
Batteries are electrochemical devices that store chemical energy and convert the chemical energy into electrical energy to deliver a required power
