Wireless Adapter for Dynamic Device Information Exchange

Solution Overview

Problem

Conventional adapters require additional wires for communication with electronic devices, increasing BOM costs and making power cords heavier and less portable, especially in low-power applications, while only allowing for fixed and simple information exchange.

Innovation Solution

Incorporating a first information acquiring unit and a first wireless communication unit in the adapter, and a second information acquiring unit and a second wireless communication unit in the electronic device, enabling wireless transmission and reception of adapter and electronic device information, eliminating the need for signal wires and allowing for intelligent interaction.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If additional wires are added for communication between adapter and electronic device, then communication capability is improved, but BOM cost increases and portability deteriorates

Engineering Contradiction:

Improvecommunication capabilityVSAvoidportability

Core Design Contradiction:

Adaptability or versatilityVSWeight of moving object

Solution Approach 1:

The patent replaces the mechanical wire-based communication system with a wireless communication system. The adapter and electronic device are equipped with wireless communication modules that enable data exchange without physical connections, thereby eliminating the need for additional signal wires and improving portability while maintaining communication capability.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent extracts the communication function from the physical wire connection and implements it through wireless communication modules integrated into the adapter and electronic device. This separation allows the power transmission function to remain wire-based while the communication function becomes wireless, resolving the contradiction between communication capability and portability.
