Solution Overview

Problem

Conventional adapters with USB type C plugs and micro B receptacles can only recognize connections with host devices, such as computers or chargers, and not with OTG devices, like memories or electric fans, leading to noise signal interference during data communication.

Innovation Solution

A connector device with specific terminal configurations and resistors allows an electronic device with a USB type C plug to recognize and connect with both host and OTG devices, reducing noise signal interference by using conducting lines and resistors to identify device connections and manage signal flow.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional adapters with USB type C plugs and micro B receptacles are used, then connection with host devices is recognized, but connection with OTG devices cannot be recognized and noise signal interference occurs

Engineering Contradiction:
Improvedevice recognition capabilityVSAvoidconnection stability
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The patent applies local quality by configuring different resistors at different terminal locations within the adapter. Specifically, a first resistor is connected between the second terminal and seventh terminal, while a second resistor is connected to the second conducting line. These locally differentiated resistor configurations enable the adapter to distinguish between host devices and OTG devices through unique electrical characteristics at different connection points, thereby achieving both broad adaptability and reliable device identification.

Inventive Principle:
Principle #3Local quality

2Adaptability or versatility

If a single adapter is used for both host and OTG devices, then device compatibility is expanded, but noise signal interference during data communication increases

Engineering Contradiction:
Improveconnector compatibilityVSAvoidnoise signal interference
Core Design Contradiction:
Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The patent uses resistors as intermediary elements between the USB type C plug and micro B receptacle terminals. The first resistor connected between the second terminal and seventh terminal, and the second resistor connected to the second conducting line, act as electrical mediators that condition the signal flow. These intermediary resistors filter and regulate the electrical signals passing through the adapter, reducing noise and signal interference while maintaining compatibility with both host and OTG devices.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Reliability

If separate adapters are used for host devices and OTG devices, then noise interference is reduced, but device complexity and user burden increase

Engineering Contradiction:
Improvesignal communication qualityVSAvoidadapter configuration
Core Design Contradiction:

Solution Approach 1:

The patent implements universality by designing a single adapter that can function with both host devices and OTG devices. The adapter incorporates a USB type C plug and micro B receptacle with specifically configured resistors that enable it to automatically adapt to different device types. This multi-functional design eliminates the need for users to purchase and manage separate adapters for different device categories, reducing complexity while maintaining reliable signal communication through the resistor-based identification system.
