Solution Overview

Problem

Existing display modules in small household appliances have complex installation modes and high costs due to the integration of display components with driving circuit boards, increasing assembly time and overall cost.

Innovation Solution

A display device with a flexible circuit board integrated into a single piece, including a bending portion and a device mounting portion, where the processor is coupled to the display module, reducing the need for separate assembly with a driving circuit board and utilizing a cost-effective, lightweight flexible circuit board design.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a display module and system board are integrated with a driving circuit board, then the display device can provide complete display and control functions, but the installation mode becomes complex and the cost increases

Engineering Contradiction:

Improvedisplay functionVSAvoidinstallation mode

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent merges the display module and the driving circuit board into a single integrated display device. The flexible circuit board integrates both the display panel and the driving circuit board, eliminating the need for separate assembly and reducing installation complexity while maintaining complete display functionality.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The flexible circuit board serves multiple functions: it acts as both the display panel support and the driving circuit board, providing mechanical support, electrical connection, and signal transmission functions in a single component, thereby reducing overall device complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If a display module and system board are integrated with a driving circuit board, then the display device can provide complete display and control functions, but the cost increases

Engineering Contradiction:

Improvedisplay functionVSAvoidcost

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

Inventive Principle:

Principle #5Merging (Combining)

3Weight of moving object

If a flexible circuit board is used instead of a rigid circuit board, then the weight and thickness are reduced, but the structural strength may be compromised

Engineering Contradiction:

Improvedisplay device weightVSAvoidcircuit board strength

Core Design Contradiction:

Weight of moving objectVSStrength

Solution Approach 1:

The patent employs a flexible circuit board made of flexible printed circuit board material that provides both flexibility and structural strength. The flexible circuit board is designed with appropriate thickness and material properties to maintain sufficient mechanical strength while achieving weight reduction and thinness requirements.

Inventive Principle:

Principle #30Flexible shells and thin films
