Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If content is provided separately to each augmented reality device, then each device can operate independently, but content sharing and synchronization between devices cannot be achieved

Engineering Contradiction:

Improvecontent sharing capabilityVSAvoidsystem complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

A hub device is introduced as an intermediary between multiple augmented reality devices and a server. The hub collects content from the server, modifies it according to device characteristics, and distributes it to connected AR devices. This mediator approach enables content sharing and synchronization without requiring complex peer-to-peer communication between devices, thus achieving content adaptability while managing system complexity.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The hub device performs multiple functions: it acts as a content collection point from the server, a modification station that adapts content to different device characteristics, and a distribution center that transmits content to multiple AR devices simultaneously. This multi-functionality enables the system to achieve content sharing across diverse devices through a single universal component.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If content is customized for each augmented reality device, then device-specific optimization is achieved, but content consistency across devices cannot be maintained

Engineering Contradiction:

Improvedevice-specific content optimizationVSAvoidcontent consistency

Core Design Contradiction:

Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

The hub modifies content based on the specific characteristics of each augmented reality device while maintaining the core content structure. Different devices receive customized versions of the same content tailored to their specific capabilities and features, achieving local optimization without compromising the overall content consistency and synchronization across the system.

Inventive Principle:

Principle #3Local quality

3Productivity

If a server provides content directly to each augmented reality device, then content delivery is straightforward, but content sharing between devices cannot be achieved

Engineering Contradiction:

Improvecontent delivery efficiencyVSAvoidcontent sharing capability

Core Design Contradiction:

ProductivityVSAdaptability or versatility

Solution Approach 1:

The hub merges the roles of content receiver, content modifier, and content distributor into a single device. Instead of the server communicating separately with each AR device, all content flow is consolidated through the hub, which efficiently manages content delivery to multiple devices while enabling sharing and synchronization capabilities.

Inventive Principle:

Principle #5Merging (Combining)

4Ease of operation

If multiple augmented reality devices operate independently, then device autonomy is maintained, but synchronized content implementation cannot be achieved

Engineering Contradiction:

Improvedevice autonomyVSAvoidcontent synchronization

Core Design Contradiction:

Ease of operationVSStability of the object's composition

Solution Approach 1:

The hub performs preliminary content modification and preparation before distributing content to augmented reality devices. By pre-processing content according to device characteristics and synchronizing it through the hub, devices can operate autonomously while ensuring content consistency and synchronization is maintained across all devices in the system.

Inventive Principle:

Principle #10Preliminary action
