Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Users expect seamless and timely interactions with cloud-based resources through local devices, but existing systems often disrupt user activities with uncontrolled audio announcements from third party cloud-based resources, leading to a need for managing when and how these announcements are delivered.

Innovation Solution

Implementing a token management system where first party cloud-based resources generate and manage tokens for third party cloud-based resources, limiting the number, frequency, and time window for audio announcements, ensuring they are delivered only when authorized and relevant to the user's context.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If audio announcements from third party cloud-based resources are delivered without restriction, then users receive timely information, but user activities are disrupted by uncontrolled announcements

Engineering Contradiction:

Improveinformation delivery reliabilityVSAvoiduser activity disruption

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The system performs preliminary actions by establishing authorization tokens and time windows before actual announcement delivery. The first party cloud-based resource pre-authenticates third party resources and pre-defines delivery constraints, ensuring that only authorized announcements within valid time windows are delivered, thus preventing disruptions while maintaining reliable information delivery

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The first party cloud-based resource acts as an intermediary between third party cloud-based resources and local devices. It receives announcements from third party resources, validates authorization tokens, checks time window validity, and selectively forwards approved announcements to local devices, thereby filtering out harmful disruptions while preserving useful information

Inventive Principle:

Principle #24Intermediary (Mediator)

2Quantity of substance

If multiple third party cloud-based resources send audio announcements freely, then comprehensive information is provided, but announcement frequency and relevance are uncontrolled

Engineering Contradiction:

Improveinformation quantityVSAvoidannouncement management

Core Design Contradiction:

Quantity of substanceVSEase of operation

Solution Approach 1:

The system implements feedback mechanisms where the first party cloud-based resource monitors announcement delivery patterns and token validity. It provides feedback to third party resources about authorization status and time window constraints, enabling dynamic control of announcement frequency and relevance while maintaining comprehensive information flow

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The authorization tokens include dynamic time windows that automatically expire after specified durations. This dynamic constraint allows comprehensive information delivery within valid periods while automatically reducing announcement frequency as tokens expire, providing ease of operation through automatic time-based management

Inventive Principle:

Principle #15Dynamics

3Device complexity

If authorization tokens are not validated, then announcement delivery is simple, but system integrity is compromised by counterfeiting

Engineering Contradiction:

Improveauthentication system complexityVSAvoidsystem integrity

Core Design Contradiction:

Device complexityVSReliability

Solution Approach 1:

The system performs preliminary authentication by issuing signed authorization tokens before announcement delivery. The first party cloud-based resource pre-validates third party resources and embeds cryptographic signatures in tokens, creating a reliable authentication foundation that prevents counterfeiting while maintaining manageable system complexity

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system uses cryptographic signature copying where the first party cloud-based resource creates signed copies of authorization tokens that third party resources can present. These signed tokens serve as verified copies of authorization, enabling reliable authentication without requiring complex real-time verification systems

Inventive Principle:

Principle #26Copying

AI summary

A system enables end user devices to receive audio announcements from third party cloud-based resources. For example, the system may include a first party cloud-based resource providing tokens to the third party cloud-based resource in order to prevent the third party cloud-based resource from causing audio announcements to be output by user devices without authorization. In some cases, the tokens may be time based and prevent the third party cloud-based resource from causing audio announcements to be output by user devices after a predefined amount of time. In other examples, the tokens may be use based and prevent the third party cloud-based resource from causing the user device to output more than a predetermined number of audio announcements.
