Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If living donor organs are used for transplant, then organ availability is improved, but transplant rejection and infections occur
Solution Approach 1:
The patent applies copying by creating artificial copies of organs through bioprinting technology. Instead of using donor organs that cause immune rejection, the invention prints functional organ copies using patient-specific cells, eliminating the harmful immune response while providing adequate organ quantity for transplantation.
Solution Approach 2:
The patent utilizes parameter changes by controlling the physical and biological parameters of bio-ink materials during the bioprinting process. By adjusting parameters such as cell density, material composition, and printing conditions, the invention creates functional organs that match patient requirements without triggering immune rejection, thus resolving the contradiction between organ availability and transplant safety.
2Reliability
If traditional drug discovery methods are used, then therapeutic candidates are identified, but the process is lengthy and expensive
Solution Approach 1:
The patent applies self-service by using bioprinted human tissues and organs to perform drug screening and testing functions. Instead of relying on traditional animal models or cell cultures that require lengthy validation, the invention creates human-specific test models that provide more accurate and faster therapeutic efficacy assessment, reducing both time and cost while maintaining high reliability.
Solution Approach 2:
The patent replaces traditional mechanical and chemical drug discovery methods with biologically-based bioprinting systems. By substituting conventional high-throughput screening with bioprinted tissue models, the invention accelerates the drug discovery process while improving the predictive accuracy of therapeutic efficacy, thus resolving the contradiction between reliability and time loss.
3Object-affected harmful factors
If bioprinting is used to fabricate tissues and organs, then transplant rejection is eliminated, but device complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the bioprinter system into modular components including printer heads, cartridge systems, and control modules. This modular architecture manages device complexity by allowing independent optimization and maintenance of each component while collectively achieving the function of eliminating transplant rejection through precise bioprinting capability.
Solution Approach 2:
The patent utilizes universality by designing a bioprinter system capable of printing multiple tissue types and organ structures using standardized bio-ink cartridges. This multi-functional approach manages complexity by using a single versatile platform to address various transplantation needs, rather than requiring separate specialized devices for each tissue type.
