Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If opaque conductive materials are used for antennas in the display region, then wireless connectivity is achieved, but display quality and reliability deteriorate

Engineering Contradiction:

Improvewireless connectivityVSAvoiddisplay quality

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent applies transparency changes to the antenna material, transforming it from opaque to transparent. This allows the antenna to become visually imperceptible when integrated into the display region, eliminating the visual defects and reliability issues associated with traditional opaque conductive materials while maintaining wireless connectivity functionality.

Inventive Principle:

Principle #32Color changes

Solution Approach 2:

The patent introduces a transparent conductive material as an intermediary substance that replaces traditional opaque conductive materials. This intermediary material serves as the antenna element while being optically compatible with the display region, thus resolving the conflict between wireless functionality and display quality.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Adaptability or versatility

If additional antennas are added to support more wireless standards, then wireless versatility is improved, but device space and display quality deteriorate

Engineering Contradiction:

Improvewireless standards supportVSAvoiddisplay region space

Core Design Contradiction:

Adaptability or versatilityVSArea of stationary object

Solution Approach 1:

The patent makes the display region itself multi-functional by enabling it to serve both as a display area and as an antenna region for wireless communication. The transparent antenna integrated into the display region allows the same physical space to fulfill multiple functions, eliminating the need for additional dedicated antenna spaces.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent merges the antenna function with the display region by integrating transparent conductive antenna elements directly into the display structure. This combination allows wireless antenna functionality to be embedded within the display area without occupying additional space or compromising display quality.

Inventive Principle:

Principle #5Merging (Combining)
