Solution Overview

Problem

Existing flexible electronic devices face challenges in maintaining user experience and reliability due to deformation-induced damage to sensing units and electronic elements, particularly when the flexible substrate is deformed by protruding units, which can lead to poor sensing performance and potential damage.

Innovation Solution

The design of a flexible electronic device with a specific ratio of deformation region to sensing unit area and height, along with appropriate dimensions for the flexible substrate, ensures that sensing units are not easily damaged during deformation, while maintaining effective sensing capabilities.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the flexible substrate is deformed by protruding units, then the device achieves flexible deformation capability, but the sensing units and electronic elements may be damaged

Engineering Contradiction:

Improveflexible deformation capabilityVSAvoidsensing unit integrity

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The substrate is divided into a deformation region and a non-deformation region, with sensing units specifically positioned in the non-deformation region. This segmentation allows the device to achieve flexible deformation in designated areas while protecting sensing units from damage by placing them in areas that remain relatively stable during deformation.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Different regions of the substrate are assigned different functional qualities: the deformation region is designed to accommodate bending and flexing, while the non-deformation region maintains structural stability to house sensing units. This local differentiation ensures that sensing units operate in a protected environment while the device overall maintains flexibility.

Inventive Principle:

Principle #3Local quality

2Ease of operation

If sensing units are placed on the flexible substrate, then sensing functionality is achieved, but sensing performance deteriorates during deformation

Engineering Contradiction:

Improvesensing functionalityVSAvoidsensing performance

Core Design Contradiction:

Ease of operationVSMeasurement precision

Solution Approach 1:

The substrate is segmented into deformation and non-deformation regions, with sensing units exclusively positioned in the non-deformation region. This ensures that sensing operations occur in a stable area that does not undergo significant mechanical stress during device flexing, thereby maintaining measurement precision while preserving sensing functionality.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The non-deformation region acts as an intermediary zone that mediates between the flexible deformation capability of the substrate and the stability requirements of sensing units. By positioning sensing units in this intermediate region, the system achieves both flexibility and sensing accuracy.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Adaptability or versatility

If the deformation region area is increased, then flexible deformation capability is improved, but the risk of damage to electronic elements increases

Engineering Contradiction:

Core Design Contradiction:

Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The substrate area is segmented into deformation region and non-deformation region, with electronic elements and sensing units strategically positioned in the non-deformation region. This allows the deformation region to be sufficiently large to provide flexible deformation capability while ensuring that critical electronic elements remain in protected areas that do not undergo significant mechanical stress.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Different local regions of the substrate are assigned different functional qualities: the deformation region provides flexibility and adaptability, while the non-deformation region provides structural protection for electronic elements. This local quality differentiation allows the device to achieve high deformation capability without increasing damage risk to critical components.
