Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple computers are connected to a network to share 3D scan data, then data accessibility and collaboration are improved, but network traffic increases and image quality deteriorates due to repeated compression and transmission
Solution Approach 1:
The system divides the 3D scan data into multiple segments or parts that can be independently transmitted and stored. Each computer receives only the specific segment it needs rather than the complete dataset, reducing redundant transmission and compression cycles while maintaining data accessibility across the network.
Solution Approach 2:
The system introduces an intermediary server or storage mechanism that holds the master copy of 3D scan data. Instead of computers directly sharing data through repeated compression and transmission, they access the intermediary which manages data distribution and retrieval, preserving image quality while enabling collaborative access.
2Productivity
If 3D scan data is transmitted repeatedly across the network for processing and viewing, then collaboration efficiency is improved, but file size and network bandwidth consumption increase exponentially
Solution Approach 1:
The system performs preliminary actions by pre-processing and segmenting 3D scan data before distribution. Data is prepared in advance with metadata, indexing, and partitioning so that when collaborators access it, they receive only the necessary portions without requiring repeated full-data transmissions, reducing bandwidth consumption while maintaining collaboration efficiency.
Solution Approach 2:
Instead of transmitting the complete 3D scan data repeatedly, the system creates and transmits only the necessary copies or references to specific data segments. Each user receives minimal copies of the data they need rather than full duplicates, significantly reducing network bandwidth consumption while enabling collaborative work.
3Loss of energy
If 3D scan data is compressed for network transmission, then bandwidth efficiency is improved, but image quality and detail are lost
Solution Approach 1:
The system applies different compression levels to different parts of the 3D scan data based on their importance. Critical regions with fine details use lossless or low-loss compression, while less important areas use higher compression ratios. This local quality approach maintains overall image quality while improving bandwidth efficiency for transmission.
