Engineering Contradiction Analysis
1Use of energy by moving object
If 3D graphic data is transmitted in mobile environments using conventional methods, then the data can be transmitted, but the power consumption and computational complexity become excessive
Solution Approach 1:
The patent segments 3D graphic data into multiple independent 3D objects, each with its own configuration information and data stream. This segmentation allows selective decoding and processing of only necessary objects, reducing overall computational complexity and power consumption while maintaining the ability to transmit complete 3D scenes when needed.
Solution Approach 2:
The patent introduces configuration information that defines parameters for each 3D object including data type indicators, precision levels, and compression settings. By dynamically adjusting these parameters based on mobile device capabilities and network conditions, the system optimizes the balance between transmission efficiency and processing requirements, reducing power consumption and computational load.
2Quantity of substance
If 3D graphic data is compressed to reduce transmission size, then bandwidth requirements decrease, but the compression and decompression processes increase computational complexity
Solution Approach 1:
The patent divides compressed 3D graphic data into separate configuration information and individual object data streams. Each segment is independently processed and decoded, allowing mobile devices to compute only the portions needed for current display requirements, thereby reducing overall computational complexity while achieving efficient data compression.
Solution Approach 2:
The patent performs compression and organization of 3D graphic data into standardized configuration formats and individual object streams in advance, before transmission to mobile devices. This preliminary processing reduces the computational burden on mobile devices during runtime, as the data arrives in a pre-processed, easily decodable format that minimizes real-time computational requirements.
3Adaptability or versatility
If conventional 3D data formats are used, then compatibility is maintained, but the data size and transmission bandwidth requirements increase
Solution Approach 1:
The patent creates a universal configuration information format that can represent multiple 3D object types and data structures using standardized syntax and semantics. This multi-functional configuration approach enables compact representation of diverse 3D graphic data while maintaining compatibility across different platforms and devices, reducing transmission size without sacrificing adaptability.
