Solution Overview

Problem

Existing wireless mobile terminals face challenges in enhancing their communication performance while maintaining a compact and aesthetically pleasing design.

Innovation Solution

The proposed antenna device includes a frame, a support made of conductive material, and an antenna assembly comprising a first and second antenna module. The support is insulated from the first antenna module and reused as part of the second antenna units, optimizing space and improving antenna function.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the antenna device includes separate support structure and antenna units, then the antenna function is improved, but the space occupied by the device increases

Engineering Contradiction:
Improveantenna functionVSAvoidspace occupied by antenna device
Core Design Contradiction:
ReliabilityVSVolume of moving object

Solution Approach 1:

The support structure is merged with the second antenna units by making the support conductive, allowing it to serve dual purposes as both a structural support and an antenna element, thereby reducing the space occupied by separate antenna components

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The conductive support structure performs multiple functions simultaneously: it provides mechanical support for the first antenna module, acts as a second antenna unit for wireless communication, and eliminates the need for separate support and antenna components

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

2Volume of moving object

If the support is made of conductive material and reused as antenna units, then the space occupied is reduced, but the manufacturing complexity increases

Engineering Contradiction:
Improvespace occupied by antenna deviceVSAvoidmanufacturing complexity
Core Design Contradiction:
Volume of moving objectVSEase of manufacture

Solution Approach 1:

The support structure and second antenna units are merged into a single conductive component, reducing the total number of parts and simplifying the assembly process despite the requirement for conductive material

Inventive Principle:
Principle #5Merging (Combining)

3Reliability

If the first antenna module and support are insulated from each other, then the antenna performance is improved, but the device complexity increases

Engineering Contradiction:
Improveantenna performanceVSAvoiddevice complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

Insulation is applied locally only where the first antenna module contacts the support structure, rather than requiring complete insulation of the entire support, thereby minimizing the increase in device complexity while maintaining antenna performance

Inventive Principle:
Principle #3Local quality
