Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If preset vertex texture coordinates are used to acquire mapping regions, then the mapping process is simple, but the flexibility of VR image acquisition is poor

Engineering Contradiction:
Improvemapping process simplicityVSAvoidflexibility of VR image acquisition
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The patent introduces offset coefficients that can be dynamically adjusted to modify the mapping regions. Instead of using fixed preset vertex texture coordinates, the system allows dynamic adjustment of the mapping region ranges through offset coefficients, enabling flexible adaptation to different VR image acquisition requirements while maintaining a relatively simple mapping process.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent changes the parameters of the mapping process by introducing offset coefficients that modify the vertex texture coordinates. By adjusting these offset parameters, the mapping regions can be flexibly expanded or contracted to adapt to different texture image qualities and requirements, transforming the fixed parameter system into a variable one.

Inventive Principle:
Principle #35Parameter changes

2Ease of manufacture

If fixed mapping regions are used in texture images, then the processing is straightforward, but the display effect of VR image is poor

Engineering Contradiction:

Solution Approach 1:

The patent modifies the mapping region parameters by introducing offset coefficients that can adjust the size and position of mapping regions. This allows the system to optimize the mapping regions for better display effects while maintaining a relatively straightforward processing approach, resolving the contradiction between processing simplicity and display quality.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The system transitions from static fixed mapping regions to dynamic adjustable mapping regions through offset coefficients. This enables the mapping regions to be adaptively adjusted to improve VR image display effects, particularly in handling texture images with poor quality or varying characteristics.

Inventive Principle:

Solution Approach 1:

The patent introduces offset coefficients as adjustable parameters that can be modified based on texture image quality. This allows the model acquisition process to maintain efficiency while adapting to different texture qualities by dynamically changing the mapping region parameters, thus resolving the contradiction between acquisition efficiency and adaptability.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The system transforms the static model acquisition process into a dynamic one by incorporating offset coefficients that can be adjusted according to texture quality. This enables the acquisition process to remain efficient while becoming adaptable to various texture image characteristics and quality levels.

Inventive Principle:
Principle #15Dynamics
