Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If real-time three-dimensional human body reconstruction is performed using multi-angle images, then remote reproduction capability is achieved, but network resource consumption increases and frame loss occurs due to poor network quality

Engineering Contradiction:
Improveremote reproduction capabilityVSAvoidnetwork resource consumption
Core Design Contradiction:
ReliabilityVSLoss of energy

Solution Approach 1:

The patent pre-generates multiple viewpoint images from a single captured image before remote reproduction occurs. This preliminary action stores multiple perspective views in advance, eliminating the need for real-time multi-angle image transmission during actual remote reproduction, thus reducing network resource consumption while maintaining reliable remote reproduction capability

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent creates synthetic copies of the target object from a single captured image by generating multiple viewpoint images through image processing algorithms. These copied views are then transmitted instead of actual multi-angle captured images, reducing network bandwidth requirements while achieving the same remote reproduction effect

Inventive Principle:
Principle #26Copying

2Reliability

If real-time three-dimensional human body reconstruction is performed, then remote reproduction is enabled, but reconstruction effect is poor due to computational intensity

Engineering Contradiction:
Improveremote reproduction capabilityVSAvoidreconstruction effect
Core Design Contradiction:
ReliabilityVSManufacturing precision

Solution Approach 1:

The patent performs computationally intensive image processing and viewpoint synthesis in advance during a preparation phase, storing the processed results. During actual remote reproduction, only pre-processed images are transmitted and displayed, avoiding real-time computational requirements and ensuring high reconstruction quality without performance delays

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent replaces the mechanical/computational process of real-time three-dimensional reconstruction with a pre-processing approach using image synthesis algorithms. Instead of performing complex 3D reconstruction computations during remote reproduction, the system uses predetermined viewpoint images generated from single-image analysis, substituting heavy real-time computation with pre-computed visual data

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Reliability

If multi-angle images are transmitted in real time for reconstruction, then remote reproduction is achieved, but frame loss and freezing occur due to network quality issues

Engineering Contradiction:
Improveremote reproduction capabilityVSAvoidinteraction experience
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The patent extracts only the essential viewpoint information from captured images and stores pre-generated viewpoint images locally. During remote reproduction, only lightweight image data is transmitted instead of continuous multi-angle video streams, extracting and transmitting only what is necessary for maintaining reliable remote reproduction without frame loss

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent performs viewpoint synthesis and image processing in advance before remote reproduction sessions. This preliminary preparation creates a library of predetermined viewpoint images that can be quickly transmitted and displayed during actual use, ensuring smooth interaction experience without real-time processing delays or frame freezing

Inventive Principle:
Principle #10Preliminary action

AI summary

This application provides a remote reproduction method, applied to a remote reproduction system, where the system includes a first terminal worn by a first user and a second terminal worn by a second user, and the first user and the second user are located in different geographical scenarios. The method includes: The second terminal obtains an action image of the first user, where the action image of the first user includes a sequence of at least one action formed by a pre-constructed human body model of the first user, and then the second terminal reproduces, for the second user, the action image of the first user to a geographical scenario in which the second user is located. According to the method, when the second terminal side reproduces the image of the first user, a multi-angle image does not need to be transmitted in real time, thereby reducing network resource occupation, avoiding frame loss and frame freezing when network quality is poor, and improving interaction experience.
