Problem

Existing energy storage devices are prone to short circuits and voltage breakdown, which affect their efficiency and cost, making them less effective for meeting the increasing demand for renewable energy storage.

Innovation Solution

The energy storage device employs a three-dimensional array of peaks and troughs with a high dielectric material that stores electrical potential energy in the form of chemical, electrostatic, and pseudocapacitance, featuring a gap between conductors to prevent short circuits and distribute voltage across multiple troughs, reducing the risk of voltage breakdown.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If existing energy storage devices are used, then energy storage is provided, but they are prone to short circuits and voltage breakdown which reduces reliability

Engineering Contradiction:
ImprovereliabilityVSAvoidshort circuits and voltage breakdown
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The device segments the conductor into multiple isolated sections using dielectric material. Each conductor segment is separated by insulating material, preventing continuous electrical contact and potential short circuits. This segmentation isolates voltage breakdown risks to individual segments rather than affecting the entire system.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Dielectric material is introduced as an intermediary substance between the conductor segments. This intermediary provides electrical insulation while allowing the device to maintain its energy storage function, effectively preventing direct contact that would cause short circuits or voltage breakdown.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If conventional capacitor structures are used, then energy storage is achieved, but voltage breakdown occurs more frequently

Engineering Contradiction:
Improveresistance to voltage breakdownVSAvoidvoltage breakdown
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The conductor is divided into multiple isolated segments by dielectric material, creating discrete storage regions. This segmentation prevents voltage breakdown from propagating across the entire conductor, confining it to individual segments if it occurs, thereby improving overall reliability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The dielectric material serves as an intermediary insulating layer between conductor segments, providing electrical isolation that prevents voltage breakdown and short circuits. This intermediary protects the conductive paths from direct contact that would cause failure.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Quantity of substance

If material fills the troughs completely or overfills, then capacitance is increased, but short circuit risk increases

Engineering Contradiction:

Core Design Contradiction:
Quantity of substanceVSReliability

Solution Approach 1:

Dielectric material acts as an intermediary substance filling the troughs and separating conductor segments. This intermediary provides electrical insulation even when completely filling or overfilling the troughs, allowing maximum capacitance without creating direct conductive paths that would cause short circuits.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The dielectric material can be structured to fill the troughs effectively while maintaining its insulating properties. The material's structure allows it to occupy the space between conductors without creating conductive pathways, balancing capacitance enhancement with short circuit prevention.

Inventive Principle:
Principle #31Porous materials
