Solution Overview

Problem

Existing location-based service technologies face inefficiencies in managing and executing multiple applications due to storage limitations, leading to inconvenience and unnecessary installation of applications that may not be used, and lack of real-time relevance.

Innovation Solution

A display apparatus equipped with tracking means and processors that determine location and orientation to dynamically obtain and execute relevant software applications from a server, overlaying virtual content in real-time based on the device's location and orientation, eliminating the need for pre-installation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If all multiple location-based service applications are stored and installed beforehand at the display apparatus, then the applications are readily available for execution, but storage capacity is consumed and installation time is increased

Engineering Contradiction:
Improvereadiness of applicationsVSAvoidstorage capacity
Core Design Contradiction:
Ease of operationVSQuantity of substance

Solution Approach 1:

The system performs preliminary actions by pre-configuring the display apparatus with tracking means and processor capabilities to automatically identify location and retrieve relevant applications in real-time, eliminating the need to pre-install all possible applications while ensuring immediate availability of location-relevant content

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent extracts only the necessary application data from a remote server based on real-time location information, rather than storing all applications locally. This selective extraction reduces storage requirements while maintaining application availability through on-demand retrieval

Inventive Principle:
Principle #2Taking out (Extraction)

2Adaptability or versatility

If all multiple location-based service applications are installed beforehand, then the user has access to all possible services, but installation time is increased and convenience is reduced

Engineering Contradiction:
Improveaccess to all servicesVSAvoidinstallation time
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The system dynamically adapts the set of installed applications based on real-time location data. The display apparatus continuously monitors location through tracking means and automatically updates the application set to match current location-based service requirements, providing versatility without permanent installation of all applications

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The display apparatus is designed with universal capabilities to execute any location-based service application by retrieving it from a remote server. The combination of tracking means, processor, and network connectivity creates a multi-functional system that can access any service without pre-installing each one

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

3Reliability

If location-based services are provided with pre-installed applications, then the services are available, but storage capacity is limited and unnecessary applications are stored

Engineering Contradiction:
Improveavailability of servicesVSAvoidmanagement of multiple applications
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent introduces a remote server as an intermediary that stores and manages the library of location-based service applications. The display apparatus communicates with this server to retrieve only the applications relevant to the current location, reducing local storage requirements and simplifying application management while maintaining service availability

Inventive Principle:
Principle #24Intermediary (Mediator)
