Connector Adapter for Incompatible Host and Accessory Interfaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable electronic devices often have incompatible connectors due to differences in size, shape, or electrical signaling protocols, preventing compatibility with accessories designed for other devices.
Innovation Solution
An adapter with an accessory interface connector and a host interface connector, along with conversion circuitry to convert data and power signals, and authentication circuitry to ensure compatibility and safety between incompatible connectors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If connectors are made smaller and more advanced in newer models, then device portability and integration are improved, but compatibility with accessories for older models deteriorates
Solution Approach 1:
The patent employs an adapter as an intermediary device that bridges the gap between incompatible connectors. The adapter includes a first connector interface that mates with the accessory and a second connector interface that mates with the host device, thereby enabling communication between devices with different connector types without requiring modification of the original devices
Solution Approach 2:
The adapter serves multiple functions: it provides physical connection between different connector types, converts electrical signals between different protocols, and enables both data transfer and power delivery across incompatible interfaces. This multi-functionality allows a single accessory to work with multiple host device models
2Adaptability or versatility
If different connector types are used across device models, then device design flexibility and advancement are improved, but ease of operation with accessories deteriorates
Solution Approach 1:
The adapter acts as a translation intermediary that handles the complexity of connector incompatibility. Users simply need to insert the adapter between the host device and accessory, and the adapter automatically performs the necessary signal conversion and protocol translation, making the process as easy as using a standard connector
3Reliability
If authentication circuitry is added to ensure compatibility, then system reliability and safety are improved, but device complexity increases
Solution Approach 1:
The authentication circuitry performs compatibility verification before enabling full data and power transmission. The adapter checks whether the connected accessory is authorized to work with the host device, and only after successful authentication does it establish the communication channel, thereby preventing incompatible devices from causing damage

AI summary
An adapter for providing connectivity between a host connector of a host device and an accessory connector of an accessory that is incompatible with the host connector is described. The adapter can include a host interface connector that is compatible with the host connector, and an accessory interface connector that is compatible with the accessory connector of the accessory. The adapter may further include an identification module that can provide adapter identification information to a host device connected to the host interface connector, and may also include an authentication module that can authenticate an accessory connected to the accessory interface connector.
