Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of time

If communication is performed only between game server and user terminal, then system complexity is reduced, but communication delay increases leading to decreased user immersion

Engineering Contradiction:

Improvecommunication delayVSAvoidsystem complexity

Core Design Contradiction:

Loss of timeVSDevice complexity

Solution Approach 1:

The patent segments the centralized game server system into multiple distributed components: map server, augmented map server, and IoT devices. This segmentation distributes the communication load and processing tasks, reducing communication delay between server and terminal while maintaining system functionality through coordinated interactions among segmented components.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent introduces intermediary components including map server and augmented map server that act as mediators between the game server and user terminal. These intermediaries handle map data processing and augmented reality object mapping, reducing the communication burden on the direct game server-terminal connection and thereby reducing overall communication delay.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Measurement precision

If 3D modeling and mapping are performed on the server side, then mapping precision is improved, but server processing load increases

Engineering Contradiction:

Improvemapping precisionVSAvoidserver processing load

Core Design Contradiction:

Measurement precisionVSPower

Solution Approach 1:

The patent extracts the 3D modeling and mapping functions from the game server and places them in a dedicated augmented map server. This extraction separates the heavy processing tasks from the game server, reducing server processing load while maintaining mapping precision through specialized processing in the augmented map server.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent performs 3D modeling and map creation as preliminary actions before the actual game session. The augmented map server pre-processes map data and creates augmented reality object mappings in advance, so that during gameplay, the server only needs to transmit pre-processed data, significantly reducing real-time processing load while maintaining high mapping precision.

Inventive Principle:

Principle #10Preliminary action

AI summary

A method of providing a game based on augmented reality includes: performing, at an augmented map server, three-dimensional (3D) modeling based on object information about a reality object in response to extracting a location of the reality object from a map provided from a map server; mapping, at the augmented map server, an augmented reality object based on a location of the reality object in response to creating an augmented map according to performing of the 3D modeling; determining a location of a client based on beacon information of at least one Internet of Things (IoT) device configured as a beacon; and providing an augmented reality game environment by disposing the reality object on the augmented map based on the location of the client.
