Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple encoding schemes are used to represent three-dimensional objects, then adaptability and versatility are improved, but device complexity increases
Solution Approach 1:
The decoding device is designed to handle multiple encoding schemes (point cloud, mesh, 3D model) through a unified architecture that can decode and switch between different data representations, making the device versatile for various three-dimensional data formats
Solution Approach 2:
The device dynamically switches between different encoding schemes based on available capacity, network conditions, and user requests, allowing the system to adapt its operation mode rather than being fixed to a single encoding format
2Adaptability or versatility
If switching between different three-dimensional data representations is enabled, then adaptability is improved, but spatial synchronization becomes more difficult to maintain
Solution Approach 1:
The patent replaces manual or mechanical spatial alignment methods with automatic spatial synchronization mechanisms that use encoding scheme information and identification information to automatically coordinate and synchronize spatial data across different encoding formats
Solution Approach 2:
The system incorporates feedback mechanisms that monitor spatial synchronization status during switching between encoding schemes and automatically adjust to maintain spatial consistency, detecting and correcting synchronization issues in real-time
3Quantity of substance
If massive amounts of point cloud data are compressed and encoded, then data transmission efficiency is improved, but decoding and processing time increases
Solution Approach 1:
The system dynamically selects decoding strategies and switches between different encoding schemes based on available processing capacity and time constraints, allowing flexible adjustment between compression ratio and decoding speed
Solution Approach 2:
The decoding process is segmented into parallel processing paths for different encoding schemes, allowing the system to process different portions of three-dimensional data simultaneously and reduce overall decoding time
