Solution Overview

Problem

Interfacing with wireless devices is complex and difficult due to the lack of intuitive interfaces and confusing device names, especially as the number of devices increases, making it hard for users to pair and interact with them effectively.

Innovation Solution

A master device images and identifies an object device using its image, allowing automatic pairing and providing an interface to control or pass data to the object device, even for devices with limited or no interfaces, by displaying relevant information overlaid on the image and using broadcast data to filter and select the correct device.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If traditional pairing protocols are used, then device connectivity is established, but the pairing process becomes complex and time-consuming

Engineering Contradiction:
Improvepairing processVSAvoidpairing time
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The system performs preliminary actions by capturing an image of the object device and extracting identifying features before the actual pairing process. The master device pre-processes visual information to generate device identifiers, so when pairing is initiated, the identification phase is already complete or near-complete, significantly reducing the time required for the overall pairing operation.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent replaces traditional mechanical/manual pairing operations (manual protocol activation, manual device name matching) with an optical/image-based identification system. The master device uses image processing to automatically identify and retrieve object device identifiers, substituting the manual mechanical process of comparing device names with an automated visual recognition system that is both faster and more intuitive.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Difficulty of detecting and measuring

If device names are used for identification, then devices can be identified, but the names are indistinct and confusing to users

Engineering Contradiction:
Improvedevice identificationVSAvoiddevice meaning
Core Design Contradiction:
Difficulty of detecting and measuringVSLoss of information

Solution Approach 1:

Instead of relying on abstract text-based device names that may not reflect the actual device, the system creates a visual copy (image) of the object device and extracts identifying features from that visual representation. This visual copy serves as a more intuitive and accurate identifier that directly represents the physical device being identified, making it easier for users to recognize and distinguish between devices.

Inventive Principle:
Principle #26Copying

3Adaptability or versatility

If interfaces are added to every wireless device, then interaction capability improves, but device size and cost increase

Engineering Contradiction:
Improveinterface capabilityVSAvoiddevice structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The master device serves as an intermediary that provides the rich interface and image processing capabilities needed for device identification and interaction. Rather than requiring every object device to have its own complex interface, the master device acts as a mediator that captures images, processes visual information, and manages the pairing process, allowing simple object devices to gain enhanced interaction capabilities through the master device's interface.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

A master device images an object device and uses the image to identify the object device. The master device then automatically interfaces with the identified object device, for example, by pairing with the object device. The master device may receive broadcast data from the object device including information about the visual appearance of the object device and use the broadcast data in the identification of the object device. The master device may retrieve data related to the object device and display the related data, which may be display the data over the displayed image of the object device. The master device may provide an interface to control the object device or be used to pass data to the object device.
