Solution Overview

Problem

As electronic devices become thinner, the internal space narrows, making it difficult to secure the antenna structure, which can lead to the connection part between the antenna and support structures being cut off due to movement.

Innovation Solution

Incorporating extension parts with dummy patterns at designated intervals and shapes on the antenna structure to increase the stiffness of the connection part, preventing detachment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Length of moving object

If the electronic device is designed to be thinner, then the device profile is improved, but the internal space is reduced making it difficult to secure the antenna structure

Engineering Contradiction:
Improvedevice thicknessVSAvoidinternal space
Core Design Contradiction:
Length of moving objectVSVolume of stationary object

Solution Approach 1:

The antenna structure is designed to extend in the thickness direction (z-axis) of the device rather than only in the planar directions. By utilizing the vertical dimension for antenna placement and configuration, the patent enables adequate antenna dimensions and spacing within a reduced planar footprint, thus accommodating the antenna structure in thinner devices.

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

Solution Approach 2:

The antenna structure is integrated within the internal space by nesting it between other components such as the battery and housing. The antenna is positioned to overlap with the battery in the planar view, effectively utilizing the vertical stacking of components to accommodate the antenna without increasing device thickness.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Length of moving object

If the internal space is reduced, then the device becomes thinner, but the connection part between antenna and support structure may be cut off due to movement

Engineering Contradiction:
Improvedevice thicknessVSAvoidconnection stability
Core Design Contradiction:
Length of moving objectVSReliability

Solution Approach 1:

The antenna structure is pre-positioned and fixed to the support structure using a tape member before final assembly. The connection part is designed with sufficient length and proper routing to accommodate potential movements, and the tape member is applied in advance to secure the antenna, preventing connection failure during subsequent assembly or operation.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The tape member connecting the antenna structure to the support structure is designed with sufficient length and proper routing to accommodate potential movements or deformations. This provides a buffer or cushioning effect that prevents the connection from being cut off due to movement, ensuring reliable electrical connection even under stress.

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)
