Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a fixed security area virtual fence is preset to protect user safety, then user safety is improved to a certain extent, but the system cannot timely remind users of potential collisions when users have large range of actions in the virtual environment

Engineering Contradiction:
Improveuser safetyVSAvoidcollision warning capability
Core Design Contradiction:
ReliabilityVSLoss of information

Solution Approach 1:

The patent transforms the static virtual fence into a dynamic system that adapts to user actions. When the system detects that the user is performing actions such as bending down or reaching out (through sensor data analysis), the virtual fence dynamically expands or contracts to create a dynamic safety zone. This allows the system to maintain safety while providing timely warnings for specific high-risk actions, resolving the contradiction between static safety coverage and dynamic warning capability.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent implements a feedback mechanism where the system continuously monitors user actions through sensors, analyzes the data to determine action types, and provides real-time feedback by adjusting the virtual fence and issuing warnings. This closed-loop feedback system enables the virtual fence to respond to user behaviors, providing timely collision warnings while maintaining overall safety, thus resolving the information loss problem.

Inventive Principle:
Principle #23Feedback

2Reliability

If real-time 6 DoF tracking and stereoscopic alignment are used to superimpose real environment data onto virtual reality displays, then collision avoidance capability is improved, but device complexity increases

Engineering Contradiction:
Improvecollision avoidance capabilityVSAvoidsystem complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent makes the existing virtual fence system multi-functional by integrating action recognition and dynamic adjustment capabilities into the same system. The virtual fence not only provides static boundary definition but also performs real-time action monitoring, dynamic zone adjustment, and contextual warning generation. This universal approach improves collision avoidance without requiring entirely separate systems, thereby managing complexity while enhancing capability.

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

Solution Approach 2:

The patent introduces an action recognition module as an intermediary between the sensor data collection and the virtual fence adjustment. This intermediary layer processes raw sensor data to identify specific user actions, which then trigger appropriate fence adjustments and warnings. By using this intermediary, the system manages complexity through modular design while achieving improved collision avoidance through integrated 6 DoF tracking and real-time analysis.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

Embodiments of the present disclosure provide an image display method and apparatus, and an electronic device. The method includes: obtaining target position information of a user in a real environment when the user is in a virtual environment; obtaining first image data corresponding to the real environment and second image data corresponding to the virtual environment when the target position information meets a predetermined condition, both the first image data and the second image data being based on a same coordinate space; performing superposition and merging processing on the first image data and the second image data to generate third image data; and displaying the third image data, to enable the user to view environment data in the real environment when the user is in the virtual environment.
