Solution Overview

Problem

Connectors in electronic devices, such as those supporting USB 3.0 or 3.1 standards, generate electromagnetic waves that interfere with nearby wireless communication antennas, leading to decreased radiation performance due to the lack of effective shielding.

Innovation Solution

1Speed

If a connector supports high-speed data communication (USB 3.0 or 3.1 Standard), then data transmission speed is improved, but electromagnetic waves are generated that degrade the radiation performance of wireless communication antennas

Engineering Contradiction:
Improvedata transmission speedVSAvoidelectromagnetic wave interference
Core Design Contradiction:
SpeedVSObject-affected harmful factors

Solution Approach 1:

A shielding structure is introduced as an intermediary element between the connector and the wireless communication antenna. This shielding structure includes a first shielding part surrounding the connector and a second shielding part surrounding the antenna, with conductive material filling the gap between them. The conductive material acts as a mediator that blocks electromagnetic waves generated by high-speed data communication from reaching the antenna, thereby preventing degradation of radiation performance while maintaining high-speed data transmission capability.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Object-affected harmful factors

If a shield is added to the connector to interrupt electromagnetic waves, then electromagnetic wave interference is reduced, but device complexity increases

Engineering Contradiction:
Improveelectromagnetic wave interferenceVSAvoidconnector structure complexity
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The shielding structure is merged with the existing connector assembly by integrating the first shielding part, second shielding part, and conductive material filling as a unified shielding system. Rather than adding completely separate shielding components, the design combines multiple shielding elements into a coordinated structure that works together to block electromagnetic waves, thereby reducing the overall complexity increase compared to implementing multiple independent shielding solutions.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The shielding structure employs a nested configuration where the first shielding part surrounds the connector, the second shielding part surrounds the antenna, and the conductive material fills the space between these two shielding parts. This nested arrangement creates an efficient electromagnetic wave blocking system while utilizing the available space within the electronic device, thereby achieving effective shielding without proportionally increasing device complexity.

Inventive Principle:
Principle #7Nested doll (Nesting)
