Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If radiating elements are arranged in a double rod-like structure with adjustable directions, then the antenna can achieve directional signal transmission, but the installation space requirement increases and the overall appearance is impaired

Engineering Contradiction:
Improvesignal transmission capabilityVSAvoidinstallation space
Core Design Contradiction:
ReliabilityVSArea of stationary object

Solution Approach 1:

The patent transitions from traditional protruding rod-like elements to planar radiating elements arranged on a substrate surface. By changing the spatial dimension from three-dimensional protrusion to two-dimensional planar arrangement, the antenna achieves directional signal transmission while maintaining a flat profile that reduces installation space and improves appearance.

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

Solution Approach 2:

The radiating elements and reflecting elements are integrated onto a common substrate, with elements nested within the same planar structure. This nesting approach allows multiple functional elements to coexist in a compact arrangement, reducing the overall installation footprint while maintaining signal transmission capabilities.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Reliability

If traditional protruding radiating elements are used, then directional signal transmission is achieved, but the antenna cannot form an omni-directional radiation pattern and appearance is compromised

Engineering Contradiction:
Improvesignal transmission capabilityVSAvoidradiation pattern capability
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent designs the planar antenna system to achieve multiple radiation patterns including omni-directional, bidirectional, and unidirectional patterns through different element configurations. The same substrate-based structure can be adjusted to provide universal radiation pattern capabilities, eliminating the need for multiple specialized antenna structures.

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

Solution Approach 2:

The patent employs asymmetric arrangements of radiating and reflecting elements to achieve different radiation patterns. By strategically positioning elements with different orientations and configurations on the substrate, the antenna can transform between omni-directional and directional patterns as needed.

Inventive Principle:
Principle #4Asymmetry

3Adaptability or versatility

If radiating elements are placed at inclined angles on the substrate, then an omni-directional radiation pattern is formed, but the structural complexity increases

Engineering Contradiction:
Improveradiation pattern capabilityVSAvoidstructural complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent divides the antenna system into discrete radiating elements and reflecting elements that can be independently positioned and configured on the substrate. This segmentation allows each element to be optimized for specific functions while maintaining overall system simplicity through modular assembly and standardized element designs.

Inventive Principle:
Principle #1Segmentation

AI summary

The present invention provides an antenna, which includes a substrate, at least one radiating element and at least one reflecting element. The at least one radiating element is placed on the substrate at an inclined angle, and the at least one reflecting element is also placed on the substrate. The signals reflected by the at least one reflecting element substantially form an omni-directional radiation pattern through aggregation of overlapping patterns.
