Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple encoding schemes are used to represent three-dimensional data, then data presentation flexibility is improved, but spatial deviation occurs during switching between schemes
Solution Approach 1:
The patent introduces a coordinate conversion unit as an intermediary mechanism that converts coordinate information between different encoding schemes. This mediator ensures that when switching between first encoding scheme data and second encoding scheme data, the spatial coordinates are accurately transformed, preventing spatial deviation while maintaining the ability to present data in multiple formats.
2Quantity of substance
If large volumes of three-dimensional point cloud data are encoded for transmission, then data compression is achieved, but encoding complexity increases
Solution Approach 1:
The patent segments the three-dimensional point cloud data into multiple data units, each suitable for different encoding schemes. By dividing the large data volume into manageable segments, the system can apply appropriate encoding methods to each segment, reducing overall encoding complexity while achieving effective data compression for transmission and storage.
