Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of moving object

If the display screen size is increased to provide better visual experience, then the screen area is improved, but the device becomes inconvenient to carry and holds less in hand

Engineering Contradiction:

Improvedisplay screen areaVSAvoidportability

Core Design Contradiction:

Area of moving objectVSEase of operation

Solution Approach 1:

The display device is divided into multiple independent display screens (first display screen, second display screen, third display screen) that can be folded and connected through connectors. This segmentation allows the large total display area to be distributed across multiple smaller, more manageable segments that can be folded into a compact form for portability.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The display device employs foldable connectors that allow the display screens to dynamically change their spatial configuration between extended and folded states. This dynamic structure enables the device to transition from a large unfolded display configuration to a compact folded configuration, resolving the contradiction between large screen area and portability.

Inventive Principle:

Principle #15Dynamics

2Area of moving object

If the display screen size is increased to provide better visual experience, then the screen area is improved, but the power consumption increases

Engineering Contradiction:

Improvedisplay screen areaVSAvoidpower consumption

Core Design Contradiction:

Area of moving objectVSUse of energy by moving object

Solution Approach 1:

The display system is segmented into multiple independent display screens with separate control capabilities. This allows the device to activate only the necessary number of screens based on usage requirements, thereby reducing overall power consumption while still providing access to large total display area when needed.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The foldable display device enables dynamic configuration where users can extend or fold the display screens based on their immediate needs. When folded, fewer screens are active, reducing power consumption. When unfolded, more screens are active, providing larger display area. This dynamic adaptability resolves the contradiction between screen area and power consumption.

Inventive Principle:

Principle #15Dynamics

3Area of moving object

If the display screen size is increased to provide better visual experience, then the screen area is improved, but the device cost increases

Engineering Contradiction:

Improvedisplay screen areaVSAvoidmanufacturing cost

Core Design Contradiction:

Area of moving objectVSEase of manufacture

Solution Approach 1:

Instead of manufacturing one large expensive display screen, the system uses multiple smaller, more affordable display screens that can be mass-produced at lower individual costs. The segmented approach allows for better economies of scale and reduces the complexity and cost associated with manufacturing single large displays.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The same display screen modules are used across multiple configurations and device types (mobile phones, wearable devices, tablets). This universal module approach allows for standardized manufacturing processes and component reuse, reducing overall manufacturing costs while providing large display area capability across different product categories.

Inventive Principle:

Principle #6Universality (Multi-functionality)

4Volume of moving object

If small display screens are used in wearable devices to reduce size, then the device portability is improved, but the user comfort is reduced for those accustomed to larger screens

Engineering Contradiction:

Improvedevice sizeVSAvoiduser comfort

Core Design Contradiction:

Volume of moving objectVSEase of operation

Solution Approach 1:

The wearable device incorporates foldable display screens that can dynamically expand from a compact folded state to an extended unfolded state. This allows the device to maintain a small form factor for portability when folded, while providing a large display area for user comfort when unfolded, effectively resolving the contradiction between device size and user comfort.

Inventive Principle:

Principle #15Dynamics
