Solution Overview

Problem

Existing electrochromic devices require conductive layers to be arranged in stagger, leading to material waste, high production costs, and limited production capacity, and offer simplistic color-changing effects that lack diversity.

Innovation Solution

The electrochromic device design allows electrode leads to pass through additional layers without requiring staggered conductive layers, enabling efficient production and achieving gradual color-changing effects by adjusting voltage and current output.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conductive layers are arranged in stagger and manually aligned, then the electrochromic device can be connected with power supply, but material waste increases, production costs rise, and production efficiency decreases

Engineering Contradiction:

Improveelectrochromic device functionalityVSAvoidproduction efficiency

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

Instead of arranging conductive layers in stagger and cutting them to size, the patent inverts the approach by keeping conductive layers aligned and cutting the electrode leads to connect through layers. This allows full-size conductive layers to be produced without waste, then individually cut and connected electrode leads, enabling bulk production followed by precise cutting.

Inventive Principle:

Principle #13The other way round (Inversion)

Solution Approach 2:

The patent segments the electrode leads from the conductive layers. Rather than having conductive layers cut and aligned, the electrode leads are separately cut and connected to the conductive layers, allowing independent optimization of each component's production process and enabling automated manufacturing.

Inventive Principle:

Principle #1Segmentation

2Reliability

If conductive layers are arranged in stagger and manually aligned, then the electrochromic device can be connected with power supply, but labor costs and production costs highly increase

Engineering Contradiction:

Improveelectrochromic device functionalityVSAvoidproduction cost

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The patent inverts the conventional manufacturing approach by keeping conductive layers in aligned configuration (avoiding manual alignment) and instead cutting and connecting electrode leads. This inversion eliminates the need for precise manual alignment of conductive layers, significantly reducing labor costs and enabling automated production processes.

Inventive Principle:

Principle #13The other way round (Inversion)

Solution Approach 2:

The patent performs preliminary cutting of electrode leads before connection to conductive layers. This preliminary action allows standardization of components and enables automated assembly processes, reducing manual labor requirements and production costs while maintaining reliable electrical connections.

Inventive Principle:

Principle #10Preliminary action

3Device complexity

If existing electrochromic device structure is used, then simple color-changing effect is achieved, but diverse visual experience of gradual color-changing cannot be provided

Engineering Contradiction:

Improvedevice structureVSAvoidcolor-changing effect diversity

Core Design Contradiction:

Device complexityVSAdaptability or versatility

Solution Approach 1:

The patent applies local quality by creating non-uniform electrode lead arrangements or varying the connection points on conductive layers. This allows different regions of the electrochromic device to respond differently to applied voltage, enabling gradual color-changing effects and diverse visual experiences while maintaining a relatively simple overall device structure.

AI summary

Electrochromic devices, preparation methods for electrochromic devices, and applications of electrochromic devices. The electrochromic device includes a first conductive layer, a color-changing layer and a second conductive layer that are arranged in succession. At least one first electrode lead is connected on the first conductive layer. The first electrode lead passes through the color-changing layer and the second conductive layer. At least one second electrode lead is connected on the second conductive layer, and the second electrode lead passes through the color-changing layer and the first conductive layer. The electrochromic device can achieve the application of the electrochromic device under the premise that the two conductive layers are not staggered, and on the basis of implementing electrochromism. The technical effect of gradual color change can be achieved by changing the magnitude of the power supply voltage and/or current.
