Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If multiple highlight printers with different loaded toner are maintained to support various base toners, then color accuracy and application specificity are improved, but device complexity and operational burden increase
Solution Approach 1:
The patent applies universality by enabling a single full-color rendering device to simulate multiple highlight color rendering devices through software-defined color spaces. The system translates color space information from different highlight toner types (e.g., red, blue, green base toners) into corresponding full-color device color spaces, allowing one device to perform the functions of multiple specialized printers without physical reconfiguration.
2Manufacturing precision
If multiple highlight printers with different loaded toner are maintained, then color accuracy for different applications is improved, but loss of time between runs increases
Solution Approach 1:
The system enables a single device to perform multiple highlight color functions through software translation of color space information, eliminating the need to physically switch between multiple printers. This resolves the downtime issue by allowing continuous operation on a single device while maintaining color accuracy for different toner types through virtual simulation.
3Adaptability or versatility
If full color elements are added to existing highlight color jobs, then versatility and functionality are improved, but device complexity and resource requirements increase
Solution Approach 1:
The patent applies parameter changes by modifying color space translation parameters dynamically based on the base toner type and job requirements. The system translates color space information from the imaging data stream according to the specific highlight toner characteristics, enabling full-color rendering on existing highlight color devices without requiring physical hardware modifications or complex resource reallocation.
4Adaptability or versatility
If data format conversions are performed to add full color elements, then versatility is improved, but loss of energy and conversion costs increase
Solution Approach 1:
The system translates color space information parameters directly within the existing imaging data stream structure, avoiding complete data format conversions. By modifying color space translation parameters rather than converting the entire data format, the system achieves full-color capability with minimal energy consumption and conversion overhead, resolving the contradiction between versatility and energy loss.
Data Source
AI summary
A data structure comprising a user-maintained list of colors is scanned to determine if a particular color within the user-maintained list of colors has been re-defined. If the particular has been redefined within the user-maintained list of colors, the particular color is searched for and identified in an alternative data structure comprising a user-specified extensible set of alternative colors. The particular color identified in the alternative data structure can then be automatically parsed in order to extract color space and value information associated with the particular color and define image-processing operations involving the particular color. The color space associated with the particular color in the alternative data structure can then be translated to a known color space in order to provide the correct color in the printed output.
