Solution Overview

Problem

Existing hinge antennas face challenges with excessive overall cavity size and complex hinge mechanism design, often requiring additional space or compromising product reliability and appearance.

Innovation Solution

A hinge antenna is integrated onto a horizontal fixed shaft within the hinge assembly, utilizing a non-conductive antenna base and a metal fixing assembly for electrical connection, minimizing overall size while maintaining radiation efficiency and appearance integrity.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If an additional antenna area is opened in the hinge antenna, then the antenna radiation efficiency is improved, but the overall cavity size becomes excessive

Engineering Contradiction:
Improveantenna radiation efficiencyVSAvoidoverall cavity size
Core Design Contradiction:
ReliabilityVSVolume of stationary object

Solution Approach 1:

The patent merges the antenna structure with the hinge assembly by integrating the antenna base into the hinge assembly's inner space. The antenna base is positioned within the hinge assembly's cavity, and the fixing assembly simultaneously secures both the antenna base to the hinge assembly and provides the grounding connection. This merging eliminates the need for separate antenna mounting space while maintaining radiation efficiency.

Inventive Principle:
Principle #5Merging (Combining)

2Reliability

If a special hinge design is adopted to match an antenna sleeve design, then the antenna radiation efficiency is improved, but the hinge mechanism design becomes more complex

Engineering Contradiction:
Improveantenna radiation efficiencyVSAvoidhinge mechanism design
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The fixing assembly serves multiple functions: it mechanically secures the antenna base to the hinge assembly, provides the grounding connection for the antenna, and maintains the antenna's positional stability during hinge rotation. This multi-functional design eliminates the need for separate antenna mounting mechanisms and grounding structures, simplifying the overall hinge mechanism while ensuring proper antenna operation.

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

3Reliability

If a radiation opening is provided in the appearance of the casing, then the antenna radiation efficiency is improved, but the product appearance and reliability are compromised

Engineering Contradiction:
Improveantenna radiation efficiencyVSAvoidappearance integrity and product reliability
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The antenna base and radiation elements are nested within the hinge assembly's inner space, utilizing the existing cavity volume. The antenna structure is positioned inside the hinge assembly rather than requiring external openings in the casing. This nesting approach allows the antenna to radiate effectively through the hinge assembly's existing structure without compromising the external appearance or structural integrity of the device casing.

Inventive Principle:
Principle #7Nested doll (Nesting)
