Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the profile set is backed up as is, then the backup is simple and direct, but the storage device capacity requirement increases and reconstruction time is prolonged
Solution Approach 1:
The patent extracts only the essential reconstruction data from the complete profile set, separating the critical components (colorimetric data, profile parameters) from the full profile data. This extraction approach maintains backup simplicity while significantly reducing the storage capacity required, as only necessary reconstruction elements are stored rather than the entire profile set.
Solution Approach 2:
The patent segments the profile set into distinct functional components: reconstruction data (colorimetric data, profile parameters) and the complete profile set. This segmentation allows the system to store only the essential reconstruction data in the storage device while keeping the full profile set in the image processing apparatus, thereby reducing storage requirements without compromising reconstruction capability.
2Reliability
If the profile set is backed up as is, then all profile information is preserved, but the reconstruction time is prolonged
Solution Approach 1:
The patent performs preliminary extraction of reconstruction data from the complete profile set during the backup process. By pre-identifying and storing only the essential reconstruction elements (colorimetric data, profile parameters) in the storage device, the system eliminates the need to process and transfer the entire profile set during reconstruction, thereby significantly reducing reconstruction time while preserving all necessary profile information for accurate restoration.
3Quantity of substance
If size prioritized data is selected for backup, then storage capacity is reduced, but reconstruction time increases
Solution Approach 1:
The patent changes the parameter of data representation by extracting and storing only the essential reconstruction data (colorimetric data, profile parameters) rather than the complete profile set. This parameter change optimizes the balance between data size and reconstruction time by storing compressed essential information that can be quickly reconstructed into the full profile set, achieving both reduced storage requirements and efficient reconstruction.
4Loss of time
If reconstruction speed prioritized data is selected for backup, then reconstruction time is reduced, but storage capacity increases
Solution Approach 1:
The patent creates a specialized copy of the profile set in the form of reconstruction data that contains only the essential elements (colorimetric data, profile parameters) needed for rapid reconstruction. This copying approach enables fast reconstruction by storing a streamlined version that can be quickly processed and expanded into the complete profile set, optimizing the balance between storage capacity and reconstruction speed.
