Solution Overview

Problem

The integration of smart devices in home environments leads to increased maintenance demands, compatibility issues between devices and information sources, and privacy concerns due to direct data transmission, overwhelming users and complicating transactions.

Innovation Solution

A framework for an application that communicates with smart devices, determines their needs, and acts as an intermediary to manage transactions with information sources while anonymizing device information, using standardized APIs for communication and user-defined parameters to ensure compliance with user preferences.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If smart devices transmit data directly to information sources, then transaction efficiency is improved, but privacy security deteriorates due to direct data transmission

Engineering Contradiction:
Improvetransaction efficiencyVSAvoidprivacy security
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The patent introduces a user device as an intermediary component between smart devices and information sources. The user device receives item information from sources, determines device needs, and manages transactions, thereby preventing direct data transmission between smart devices and sources while maintaining transaction efficiency and protecting privacy security.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

If multiple smart devices are integrated into a single environment, then functionality is improved, but device complexity increases due to compatibility issues and maintenance demands

Engineering Contradiction:
ImprovefunctionalityVSAvoidsystem complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The user device serves as a central intermediary that manages communication between multiple smart devices and information sources. It handles compatibility issues through standardized interfaces and consolidates maintenance tasks, allowing multiple devices to function together without increasing overall system complexity for the user.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The user device performs multiple functions including receiving item information, determining device needs, managing transactions, and providing user interfaces. This multi-functional approach consolidates various device management tasks into a single universal platform, reducing the need for each smart device to have specialized communication and management capabilities.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Ease of operation

If smart devices autonomously perform tasks, then user convenience is improved, but information overload increases overwhelming users

Engineering Contradiction:
Improveuser convenienceVSAvoidinformation overload
Core Design Contradiction:
Ease of operationVSLoss of information

Solution Approach 1:

The user device acts as an intermediary that filters and manages information flow. It receives item information from sources, processes it against device needs, and only presents relevant information to the user through controlled interfaces. This prevents information overload while maintaining user convenience through autonomous task performance.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The system implements partial automation where the user device autonomously handles information processing, need determination, and transaction management, but requires user confirmation for actual purchases. This balanced approach provides convenience through automation while preventing information overload by selectively presenting only essential information to the user.

Inventive Principle:
Principle #16Partial or excessive action

AI summary

Techniques are described herein for effectuating a transaction by an intermediary. An example method can include instructing a device to monitor a status of a first item, and to transmit a first request for a target item based at least in part on the status of the first item, the target item being a same item type as the first item. Receiving, by the from the device, the first request for the target item. Determining a first source device of a plurality of source devices to which to transmit a second request for the target item. Transmitting, to the first source device of the plurality of source devices, the second request for the target item based at least in part on the determination. Receiving a confirmation of the second request.
