Solution Overview

Problem

Existing electronic devices face reduced stability during long-term operation due to deterioration of driving elements, which provide abnormal power to tunable elements, leading to instability.

Innovation Solution

The implementation of a dual power supply circuit system where the first and second power supply circuits time-divisionally drive the tunable element, alternating rest periods to reduce deterioration and enhance stability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a single driving element continuously drives the electronic element, then the electronic element can operate without interruption, but the driving element deteriorates under long-term operation reducing stability

Engineering Contradiction:

Improvestability during operationVSAvoidlong-term operation

Core Design Contradiction:

ReliabilityVSDuration of action of moving object

Solution Approach 1:

The patent divides the driving function into multiple independent driving elements (first driving element and second driving element) that alternately drive the electronic element. This segmentation allows the system to distribute the operational load, preventing any single element from deteriorating due to continuous operation, thus improving long-term stability.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent implements periodic switching between the first and second driving elements. Each driving element operates for a certain period then switches to the other, creating a periodic action pattern. This ensures that no single driving element undergoes continuous operation, reducing deterioration and maintaining stability over extended periods.

Inventive Principle:

Principle #19Periodic action

2Reliability

If multiple power supply circuits are used to time-divisionally drive the tunable element, then the likelihood of deterioration is reduced, but the device complexity increases

Engineering Contradiction:

Improvestability during operationVSAvoiddual power supply circuit system

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines multiple driving elements into a unified control system that manages their alternating operation. By merging the control logic and using shared components where possible, the system achieves the reliability benefits of multiple elements while minimizing the increase in overall device complexity.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The driving elements are designed with universal functionality, where each element can independently perform the complete driving function for the electronic element. This multi-functionality allows the system to switch between elements without requiring additional specialized components, thereby reducing complexity while maintaining reliability.

Inventive Principle:

Principle #6Universality (Multi-functionality)
