Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If large dipole antennas are used to achieve high throughput and long range performance, then wireless performance is improved, but device size and bulk increase

Engineering Contradiction:
Improvewireless performanceVSAvoiddevice size
Core Design Contradiction:
ReliabilityVSVolume of moving object

Solution Approach 1:

The antenna system divides the antenna structure into multiple discrete antenna elements (at least three facets with antenna elements mounted on each) arranged in a compact geometric configuration. This segmentation allows the antenna system to achieve desired radiation patterns and performance characteristics without requiring a single large antenna structure, thereby maintaining high throughput and long range performance while reducing overall device volume.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent transitions from conventional planar or linear antenna arrangements to a three-dimensional geometric structure with facets arranged in space. By mounting antenna elements on multiple facets of a compact frame structure and positioning them in three-dimensional space, the system achieves improved radiation characteristics and isolation within a smaller footprint, effectively utilizing spatial dimensions to overcome the size-performance tradeoff.

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

2Volume of moving object

If antenna elements are placed close together to reduce device size, then device compactness is improved, but electromagnetic isolation between elements deteriorates

Engineering Contradiction:
Improvedevice sizeVSAvoidelectromagnetic interference
Core Design Contradiction:
Volume of moving objectVSObject-generated harmful factors

Solution Approach 1:

The patent applies different local configurations to different facets of the antenna structure. Each facet is positioned and oriented to provide specific electromagnetic characteristics, and the varying orientations of different facets create natural electromagnetic isolation between closely spaced elements. This local differentiation allows compact spacing while maintaining adequate isolation through geometric diversity rather than uniform spacing.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent converts the potential harmful effect of closely spaced antenna elements (which would normally cause mutual interference) into a beneficial configuration. By carefully designing the geometric arrangement of facets and mounting orientations, the system transforms what would be interference-prone close spacing into an advantageous compact structure that achieves both size reduction and adequate isolation through its unique three-dimensional geometry.

Inventive Principle:
Principle #22Blessing in disguise (Convert harm into benefit)
