Solution Overview

Problem

Existing electronic devices face stability issues due to the deterioration of driving elements over long-term operation, leading to abnormal power supply to electronic elements.

Innovation Solution

The electronic device incorporates a tunable element driven by a first and second power supply circuit, which time-divisionally drive the tunable element, allowing the power supply circuits to rest alternately and reducing the likelihood of deterioration.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Duration of action of moving object

If a single driving element continuously drives an electronic element, then the electronic element can operate continuously, but the driving element deteriorates under long-term operation reducing stability

Engineering Contradiction:

Improvecontinuous operation timeVSAvoidstability during operation

Core Design Contradiction:

Duration of action of moving objectVSReliability

Solution Approach 1:

The patent divides the driving function into multiple driving elements (first driving element and second driving element) that alternately drive the electronic element. This segmentation allows the system to distribute the continuous operation load across multiple components, preventing any single element from deteriorating due to prolonged continuous operation.

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 predetermined period and then switches to the other element. This periodic action ensures that no single driving element operates continuously, thereby reducing deterioration and improving long-term stability.

Inventive Principle:

Principle #19Periodic action

2Reliability

If multiple power supply circuits are used to time-divisionally drive the tunable element, then the stability during long-term operation is improved, but the device complexity increases

Engineering Contradiction:

Improvestability during long-term operationVSAvoidnumber of power supply circuits

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines multiple driving functions into a single integrated driving circuit that contains both the first and second driving elements. This merging approach allows the system to achieve the reliability benefits of multiple driving elements while minimizing the increase in device complexity through shared control logic and integrated design.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The driving circuit is designed with multi-functionality, where the same circuit structure can operate in different modes (first driving element mode and second driving element mode) by switching between different operational states. This universality reduces the need for completely separate circuits and minimizes overall device complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)
