Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Temporary device connections, such as in electric vehicle charging, require a method to establish a unique wireless communication link between unknown devices without additional hardware or complex setup, as existing solutions like power line communication are cumbersome and limited to electrical applications.

Innovation Solution

A device interconnector with dual wireless communication identifiers at each end, read by corresponding units in each device, automatically sets up a dedicated two-way wireless connection upon attachment, using these identifiers to establish a secure and user-friendly communication link.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If extra wired communication is used for data transfer between temporarily connected devices, then data communication capability is improved, but device complexity and installation cost increase due to additional connectors and mixed cables

Engineering Contradiction:

Improvedata communication capabilityVSAvoidconnector complexity

Core Design Contradiction:

Loss of informationVSDevice complexity

Solution Approach 1:

The patent combines power transmission and data communication functions into a single wireless connection. The system establishes a wireless communication link between the first device and second device while simultaneously transmitting electrical energy, eliminating the need for separate wired communication channels and reducing connector complexity.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The patent replaces mechanical wired communication with wireless communication technology. Instead of using physical cables and connectors for data transfer, the system uses wireless signals to communicate between devices, thereby eliminating the need for additional connectors and mixed cables.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Loss of information

If power line communication is used for data transfer, then data communication is achieved, but additional hardware and modulation complexity are required

Engineering Contradiction:

Improvedata communication capabilityVSAvoidhardware complexity

Core Design Contradiction:

Loss of informationVSDevice complexity

Solution Approach 1:

The patent replaces power line communication hardware with wireless communication technology. Instead of modulating data on electrical voltage through additional hardware, the system uses wireless signals to transmit data between devices, simplifying the hardware requirements.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Ease of operation

If wireless connection is established without unique identification, then ease of connection is improved, but connection reliability decreases due to inability to identify correct devices

Engineering Contradiction:

Improveconnection easeVSAvoidconnection reliability

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The patent implements preliminary identification actions before establishing the wireless connection. The system reads identification data from tags attached to the second device, verifies the identity of the connected device, and confirms the connection parameters before activating the wireless power and data transmission, thereby ensuring connection reliability while maintaining ease of operation.

Inventive Principle:

Principle #10Preliminary action

4Measurement precision

If RFID tags and readers are used for device identification, then device identification capability is improved, but manufacturing cost increases

Engineering Contradiction:

Improvedevice identification accuracyVSAvoidmanufacturing cost

Core Design Contradiction:

Measurement precisionVSEase of manufacture

Solution Approach 1:

The patent uses inexpensive RFID tags that can be attached to devices rather than integrating expensive RFID identification systems into the device manufacturing process. The tags are separate, replaceable components that provide identification functionality at low cost, reducing the overall manufacturing expense while maintaining identification accuracy.

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

AI summary

A system for setting up a wireless connection between two temporarily connected devices includes a device interconnector having a first end provided with a first wireless communication identifier and a second end provided with a second wireless communication identifier, a first device having a first interconnector mating unit, a first wireless communication unit and a first reading unit and a second device having a second interconnector mating unit, a second wireless communication unit and a second reading unit. The wireless communication units of each device is configured to receive an identifier being read by the corresponding reading unit as the device interconnector is attached to the corresponding mating unit and the wireless communication unit is configured to employ this identifier in setting up, together with the other wireless communication unit, a wireless connection between the two devices.
