Contents Open System for Transparent Ad Hoc Data Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for ad hoc communication between portable terminals do not provide transparency to users about how information is transmitted, limiting the ability to deliver targeted and useful content to non-specific recipients.
Innovation Solution
A contents open system that includes a server and portable terminals with inter-terminal communication units, allowing direct communication without a mobile network, and a server with database registration and information returning capabilities, enabling users to track and manage content transmission and recipient information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If ad hoc communication is used to deliver information to non-specific portable terminals, then information delivery reach is improved, but user awareness of information transmission path deteriorates
Solution Approach 1:
The system implements feedback mechanisms where portable terminals report back to the server about received information, including terminal identifiers and reception timestamps. This creates a closed-loop information flow that maintains user awareness of transmission paths while enabling broad distribution through ad hoc communication networks.
Solution Approach 2:
A server acts as an intermediary between information providers and recipients. The server receives information from providers, manages distribution lists, and coordinates ad hoc communication events, thereby maintaining transparency of transmission paths while enabling indirect delivery to multiple terminals.
2Productivity
If direct inter-terminal communication is implemented, then communication efficiency is improved, but system complexity increases
Solution Approach 1:
The system segments functionality between portable terminals (direct communication capabilities) and servers (coordination and management). This division allows terminals to perform simple efficient direct communication while the server handles complex coordination, distribution list management, and transparency maintenance.
Solution Approach 2:
The server serves as a mediating infrastructure that simplifies the overall system by centralizing complex functions such as terminal registration, distribution list management, and communication coordination, thereby reducing the burden on individual terminals while maintaining system-wide efficiency.
3Quantity of substance
If contents are opened to multiple non-specific terminals, then content distribution reach is improved, but control over content transmission deteriorates
Solution Approach 1:
The system employs feedback mechanisms where terminals report reception status, identifiers, and timestamps back to the server. This allows the content provider to track and control distribution while maintaining broad reach, as the server can manage and monitor all transmission events centrally.
Solution Approach 2:
The server acts as a controlling intermediary that manages content distribution to multiple terminals. It maintains distribution lists, coordinates transmission events, and provides transparency information to content providers, thereby enabling broad distribution while preserving control through centralized management.

AI summary
When a user A of a terminal a sets to open image data, open data information relating to the image data is transmitted to a server 200, thereafter, when a terminal b enters the communication area X of the terminal a, image data and the ID thereof are transmitted to the terminal b from the terminal a, ID of the image data and receiving terminal information are transmitted to the server 200 from the terminal b and the receiving terminal information is recorded in a pair with open data information, thereafter, receiving terminal information is transmitted to the server 200, every time image data is transmitted between terminals 100, and is recorded in a pair with open data information.
