Solution Overview

Problem

Conventional client-server network systems fail to fully utilize the participation-based development property of shared fields, leading to ineffective communication schemes and user burden due to unique attributes in each shared field, which are not adaptable across different fields.

Innovation Solution

A network system that creates and manages shared fields by storing shared-field context and user context on a network, allowing users to access and update these contexts through a memory area, enabling seamless interaction and adaptation across different shared fields.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a client-server type network system is used to manage shared fields, then the system can provide centralized management and control, but the server becomes extremely overloaded when many users access the shared field simultaneously

Engineering Contradiction:
Improveshared field managementVSAvoidserver load
Core Design Contradiction:
ReliabilityVSPower

Solution Approach 1:

The patent segments the centralized server management into distributed peer-to-peer connections. Each user's computer acts as both client and server, managing their own context information and sharing it directly with others in the shared field, thereby eliminating the single-point overload problem while maintaining management functionality.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent extracts the context management functionality from the central server and distributes it to individual user computers. Each user maintains their own context information locally and shares it peer-to-peer, removing the burden of centralized context management from the server.

Inventive Principle:
Principle #2Taking out (Extraction)

2Adaptability or versatility

If communication schemes are customized for each shared field to utilize participation-based development property, then the communication effectiveness improves in that specific field, but the scheme becomes ineffective in other shared fields

Engineering Contradiction:
Improvecommunication scheme effectivenessVSAvoidcommunication scheme variety
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent creates a universal context information structure that can be applied across all shared fields. The context information format is designed to be generic yet adaptable, allowing the same communication framework to serve multiple different shared fields with their unique characteristics, thereby achieving both universality and adaptability.

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

Solution Approach 2:

The patent allows communication schemes to adapt to different shared fields by changing parameters within the universal context structure. Rather than creating entirely different communication schemes, the system modifies context parameters (such as user attributes, interaction history, field-specific rules) to optimize communication for each specific shared field while maintaining the overall framework.

Inventive Principle:
Principle #35Parameter changes

3Productivity

If each shared field has unique attributes to optimize its specific functionality, then the shared field performs well for its intended purpose, but users experience burden when moving between different shared fields

Engineering Contradiction:
Improveshared field functionalityVSAvoiduser adaptation burden
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

The patent implements homogeneity in the context information structure across all shared fields. User context information (preferences, attributes, interaction history) is maintained in a standardized format that travels with the user regardless of which shared field they access, creating a consistent user experience across diverse shared fields while allowing each field to maintain its unique functional attributes.

Inventive Principle:
Principle #33Homogeneity

4Adaptability or versatility

If the system stores detailed context information for each user and shared field to enable seamless adaptation, then user experience improves, but the memory requirements and data management complexity increase

Engineering Contradiction:
Improveuser context adaptationVSAvoidcontext data volume
Core Design Contradiction:
Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

The patent extracts only the essential context information needed for user adaptation and stores it in a compact, standardized format. Rather than storing all possible user data, the system identifies and stores only the critical context elements (user attributes, preferences, interaction history) that enable seamless adaptation across shared fields, thereby reducing data volume while maintaining adaptability.

Inventive Principle:
Principle #2Taking out (Extraction)

AI summary

On a network, there are provided a plurality of shared fields enabling a plurality of computers to interact with each other. The computer is allowed to move between the shared fields anytime. Upon leaving a shared field, the computer records, on the network, contexts including identification of another computer relating to the interaction. When participating in another shared field, the user reads out the contexts from the network and reflects them on another interaction held in the latter shared field. Thus, interactions on shared fields act on construction of global fields for interactions.
