Solution Overview

Problem

Traditional USB connectors have complex manufacturing processes and large sizes due to multiple components, which increase costs and restrict their use in ultra-thin electronic products, and they face challenges with high-speed transmission and signal crosstalk.

Innovation Solution

An electrical connector design featuring an insulating body with vertically aligned upper and lower conductive terminals that are fixedly connected by riveting, allowing for simplified manufacturing, reduced size, and high-speed transmission without additional metal spacers, and incorporating features like isolating pieces and side shields to prevent signal crosstalk.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional USB connector design with multiple components (metal spacer, terminal groups, plastic bodies, holder, metal housing) is used, then high-speed transmission capability is achieved, but manufacturing process becomes complex and manufacturing cost increases

Engineering Contradiction:

Improvehigh-speed transmission capabilityVSAvoidmanufacturing process complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines multiple traditional components (terminal groups, plastic bodies, holder) into a single integrated connector body. The conductive terminals are directly embedded in the insulating body, eliminating the need for separate metal spacers and holders, thereby simplifying the manufacturing process while maintaining high-speed transmission capability through proper terminal arrangement and grounding structure

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The insulating body serves multiple functions simultaneously: it provides mechanical support, electrical insulation, signal transmission pathways, and grounding connections. The integrated design makes the connector body a multi-functional component that replaces several traditional parts, reducing assembly steps and manufacturing complexity

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If two rows of soldering pins are provided for positive and negative connections, then connection functionality is improved, but connector size increases and space occupation increases

Engineering Contradiction:

Improveconnection functionalityVSAvoidconnector size

Core Design Contradiction:

Adaptability or versatilityVSVolume of moving object

Solution Approach 1:

The patent transitions from a planar two-row soldering pin arrangement to a three-dimensional vertical arrangement. Conductive terminals are positioned at different heights (upper and lower contact portions) and connected via vertical pathways through the insulating body, allowing full connection functionality within a compact footprint suitable for ultra-thin electronic products

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

3Adaptability or versatility

If two rows of soldering pins are arranged side by side, then connection capability is provided, but soldering and testing difficulty increases

Engineering Contradiction:

Improveconnection capabilityVSAvoidsoldering and testing ease

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The connector terminals are segmented into distinct upper and lower contact portions with vertical alignment. This segmentation creates separate, accessible connection points that can be individually soldered and tested, eliminating the complexity of simultaneous two-row soldering operations and improving manufacturing ease

Inventive Principle:

Principle #1Segmentation

4Strength

If additional metal spacers are used for terminal connection, then structural support is improved, but connector size increases and manufacturing complexity increases

Engineering Contradiction:

Improvestructural supportVSAvoidconnector size

Core Design Contradiction:

StrengthVSVolume of moving object

Solution Approach 1:

The patent uses composite construction where conductive terminals (metal) are embedded within an insulating body (plastic or ceramic). This composite structure provides both mechanical support and electrical functionality without requiring separate metal spacers, reducing overall connector size while maintaining structural integrity

Inventive Principle:

Principle #40Composite materials
