Solution Overview

Problem

Portable devices providing legacy augmented reality services face challenges in displaying information effectively, as they show augmented reality images for a fixed duration regardless of the image type, making it difficult for users to obtain preferred information.

Innovation Solution

A portable device equipped with a camera unit, display unit, and processor that detects stationary and moving objects, adjusting the display time of corresponding augmented reality images based on their types and movements, allowing for dynamic timer adjustments.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a fixed display time is used for all augmented reality images, then the device operation is simple, but the user cannot obtain preferred information effectively

Engineering Contradiction:

Improvedevice operation simplicityVSAvoiduser information acquisition

Core Design Contradiction:

Ease of operationVSLoss of information

Solution Approach 1:

The patent applies dynamics by making the display time adjustable based on object characteristics. The processor dynamically sets different display durations for stationary objects versus moving objects, transforming the fixed display time system into an adaptive one that responds to real-time object detection results.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent changes the time parameter of augmented reality image display based on object type. When a stationary object is detected, a first display time is applied; when a moving object is detected, a second display time is applied. This parameter change enables optimized information delivery without requiring complex user intervention.

Inventive Principle:

Principle #35Parameter changes

2Loss of information

If the augmented reality image display time is extended to provide more information, then user information acquisition improves, but power consumption increases

Engineering Contradiction:

Improveuser information acquisitionVSAvoiddevice power consumption

Core Design Contradiction:

Loss of informationVSUse of energy by moving object

Solution Approach 1:

The patent optimizes the time parameter based on object characteristics. By detecting whether an object is stationary or moving, the system applies appropriate display durations - avoiding unnecessarily long display times for moving objects that users may not have time to observe, thus reducing power consumption while maintaining effective information delivery.

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The system uses feedback from object detection to control display duration. The processor continuously monitors object characteristics and adjusts display time accordingly, creating a closed-loop system that balances information provision with energy efficiency based on real-time conditions.

Inventive Principle:

Principle #23Feedback

3Use of energy by moving object

If the display time is shortened to save power, then power consumption decreases, but user information acquisition becomes insufficient

Engineering Contradiction:

Improvedevice power consumptionVSAvoiduser information acquisition

Core Design Contradiction:

Use of energy by moving objectVSLoss of information

Solution Approach 1:

The patent applies different time parameters for different object types. Stationary objects receive longer display times to ensure complete information delivery, while moving objects receive optimized display times that balance power savings with effective information provision, preventing information loss in both scenarios.

Inventive Principle:

Principle #35Parameter changes

4Loss of information

If different display times are applied based on object types, then user information acquisition improves, but device complexity increases

Engineering Contradiction:

Improveuser information acquisitionVSAvoiddisplay control complexity

Core Design Contradiction:

Loss of informationVSDevice complexity

Solution Approach 1:

The system performs self-service by automatically detecting object characteristics and adjusting display times without user intervention. The processor autonomously determines whether objects are stationary or moving and applies appropriate display durations, eliminating the need for complex user controls or manual configuration.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The system uses automatic feedback loops where object detection results directly control display parameters. This self-regulating mechanism simplifies the user interface while achieving optimized information delivery, as the system adapts automatically based on real-time detection without requiring complex user-side complexity.

Inventive Principle:

Principle #23Feedback
