Solution Overview

Problem

Existing social networking services based on pre-existing user relations have limitations, such as involuntary sharing of sensitive information and difficulty in communication between unacquainted individuals with little in common, as relationships are often permanent and not easily terminated.

Innovation Solution

An information distribution system that groups users based on their location by using unique identification data from wireless devices installed at specific locations, allowing for restricted data distribution to users currently within or near those locations, enabling communication without requiring pre-existing relationships.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If users are linked based on pre-existing relations in SNS, then communication between acquaintances is facilitated, but users cannot easily terminate relationships and sensitive information may be inadvertently shared

Engineering Contradiction:
Improveease of communicationVSAvoidflexibility of relationship management
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The patent applies dynamics by making user relationships transient rather than permanent. Users are automatically linked when they share the same location (detected via radio signal reception) and automatically unlinked when they stop sharing the location. This dynamic relationship model allows users to easily communicate when needed while automatically terminating relationships when no longer relevant, resolving the contradiction between ease of communication and flexibility of relationship management.

Inventive Principle:
Principle #15Dynamics

2Stability of the object's composition

If users are linked based on pre-existing relations, then existing social connections are maintained, but users cannot easily meet new people with different backgrounds

Engineering Contradiction:
Improvestability of user relationshipsVSAvoidability to form new connections
Core Design Contradiction:
Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The patent inverts the traditional SNS approach by not requiring pre-existing relationships to connect users. Instead of linking users through mutual acquaintances or profiles, the system links users based on their current physical proximity (same location detection). This inversion allows users to naturally form connections with strangers they encounter in person, while maintaining stability through the objective criterion of shared location rather than subjective relationship management.

Inventive Principle:
Principle #13The other way round (Inversion)

3Adaptability or versatility

If location-based grouping is implemented, then temporary and anonymous interaction is enabled, but system complexity increases due to radio signal reception and classification requirements

Engineering Contradiction:
Improvetemporary interaction capabilityVSAvoidsystem complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies self-service by having wireless terminals automatically perform radio signal reception, identification data extraction, and group classification without requiring manual user intervention. The terminal autonomously determines its location based on received signals, automatically joins appropriate groups, and manages its own relationship status. This automation reduces the perceived complexity for users while enabling flexible temporary interactions based on location.

Inventive Principle:
Principle #25Self-service

AI summary

To assist communication by users, who are associated according to their location. Each of APs (Access Points) 3001 to 300m is installed at a certain place, and sends a radio signal including identification data. Each of wireless terminals 4001 to 400n, when receiving a radio signal, transmits send data including identification data to information distribution apparatus 100. Information distribution apparatus 100 classifies wireless terminals 4001 to 400n into groups based on pieces of identification data, and realizes communication between users belonging to a group. Each group is associated with a particular place.
