Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If different conduction patterns are designed in various positions, then the antenna function is achieved, but the light transmittance varies across regions affecting appearance quality

Engineering Contradiction:
Improveantenna functionVSAvoidlight transmittance uniformity
Core Design Contradiction:
ReliabilityVSIllumination intensity

Solution Approach 1:

The patent applies local quality by designing different conduction patterns (first, second, and third patterns) in different regions (first function region, second function region, second dummy region, third function region) of the grid layers. Each region has specifically tailored conduction patterns optimized for its local function, allowing the antenna to achieve reliable electromagnetic wave control while managing light transmittance characteristics in each zone through the overlapping multi-layer structure

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent transitions from a single-layer conduction pattern to a multi-layer three-dimensional structure. By stacking first, second, and third grid layers at different positions with overlapping function regions, the solution adds the vertical dimension to distribute conduction patterns across multiple planes. This dimensional change allows light to pass through multiple transparent or semi-transparent layers, improving overall light transmittance uniformity while maintaining antenna functionality through the combined effect of all layers

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Illumination intensity

If multiple grid layers with overlapping function regions are used, then appearance quality is improved, but device complexity increases

Engineering Contradiction:
Improvelight transmittance uniformityVSAvoidstructure complexity
Core Design Contradiction:
Illumination intensityVSDevice complexity

Solution Approach 1:

The patent implements multi-functionality by designing each grid layer to serve multiple purposes simultaneously. The first, second, and third grid layers collectively provide antenna radiation, signal reception, ground plane functions, and light modulation capabilities. The overlapping function regions across layers enable each layer to contribute to both electromagnetic performance and optical appearance, reducing the need for separate dedicated components and thereby managing complexity despite the multi-layer structure

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent merges the antenna radiation function, ground plane function, and light control function into a single integrated multi-layer grid structure. The first, second, and third grid layers are combined with overlapping regions that perform multiple functions simultaneously - the second grid layer's second function region overlaps with the first grid layer's first function region to create combined radiation and ground effects, while the second dummy region provides additional light transmittance control without requiring separate components

Inventive Principle:
Principle #5Merging (Combining)

AI summary

An antenna device includes a first grid layer, a second grid layer, and a first insulation layer. The first grid layer has a first function region. The second grid layer has a second function region and a second dummy region electrically insulated from the second function region. The first insulation layer is disposed between the first grid layer and the second grid layer, and the first function region overlaps the second function region.
