Solution Overview

Problem

Existing systems lack the ability to efficiently control and manage the sharing of contact and calendar information, particularly in allowing users to customize the level of access and communication methods for their contacts.

Innovation Solution

A system and method that allows users to control the contact information shared with their contacts, enabling different levels of access and communication methods, and utilizing a blockchain to encrypt and store user data, limiting access by application providers and servers.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If users share complete contact information with all contacts, then communication connectivity is improved, but user privacy and data security deteriorate

Engineering Contradiction:

Improvecommunication connectivityVSAvoidprivacy risk

Core Design Contradiction:

Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The patent segments contact information into different categories (e.g., public information, private information, confidential information) and applies different sharing permissions to each category. Users can selectively share specific types of information with different contacts rather than sharing all information uniformly, thus maintaining privacy while enabling necessary communication connectivity.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent implements local quality by allowing different privacy levels and access permissions for different contacts or contact groups. Each contact can be assigned specific access rights to particular information fields, enabling users to provide tailored information access based on individual contact relationships while protecting overall privacy.

Inventive Principle:

Principle #3Local quality

2Adaptability or versatility

If users provide multiple communication methods to contacts, then communication flexibility is improved, but information management complexity deteriorates

Engineering Contradiction:

Improvecommunication flexibilityVSAvoidinformation management complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements dynamic communication method selection where users can switch between different communication channels (email, phone, messaging apps, etc.) based on the situation. The system dynamically manages multiple communication methods by allowing users to set default preferences and override them as needed, maintaining flexibility without requiring manual management of each method.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent creates a universal contact management system that handles multiple communication methods through a single interface. The system consolidates management of email, phone, messaging, and other communication channels into one unified platform, enabling users to manage all communication methods simultaneously without dealing with each separately.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Reliability

If application providers access user data for service delivery, then service quality is improved, but data security and user control deteriorate

Engineering Contradiction:

Improveservice qualityVSAvoiddata exposure risk

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent introduces an intermediary layer (the contact management system) between users and application providers. This intermediary selectively shares information with service providers based on user-defined permissions, enabling service delivery while preventing unnecessary data exposure. The system acts as a gatekeeper that facilitates service quality without compromising user control or data security.

Inventive Principle:

Principle #24Intermediary (Mediator)

4Object-affected harmful factors

If users control access to their contact information, then privacy security is improved, but ease of sharing information deteriorates

Engineering Contradiction:

Improveprivacy securityVSAvoidease of sharing

Core Design Contradiction:

Object-affected harmful factorsVSEase of operation

Solution Approach 1:

The patent implements preliminary action by allowing users to pre-configure privacy settings, sharing permissions, and communication preferences before actually sharing information. Users can set up default rules for different contacts and situations in advance, so that when sharing occurs, the system automatically applies these pre-established permissions without requiring real-time decision-making, thus maintaining both security and ease of use.

Inventive Principle:

Principle #10Preliminary action

AI summary

Some embodiments provide a system or a method to facilitate communication between people. The user can have control over which contact information fields are initially shared and subsequently updated with each contact. The system may also store information about when and how a contact was created. The system may also use blockchain to secure and store user information.
