Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional microlipoinjection process is used, then fat transplantation can be performed, but the procedure is cumbersome and time-consuming with high risk of fat cell damage
Solution Approach 1:
The patent combines multiple separate steps (liposuction, washing, centrifugation, and injection) into a single integrated closed system. The system allows tissue to be harvested, washed, and prepared for injection without removing it from the sterile field, eliminating the need for separate centrifugation steps and reducing procedural time while maintaining high fat cell survival rates.
Solution Approach 2:
The patent introduces a sterile barrier system that acts as an intermediary between the non-sterile external environment and the sterile internal processing environment. This barrier allows washing and processing to occur within the sterile field without compromising sterility, thereby reducing procedural time and eliminating the need for separate sterile processing steps.
2Ease of operation
If conventional instruments are used, then fat transplantation can be performed, but the instruments are clumsy and ill-suited for the procedure
Solution Approach 1:
The system is divided into distinct functional modules: a harvesting component with cannula, a washing chamber with filter, and an injection component. Each module is optimized for its specific function, allowing precise tissue separation and processing while maintaining ease of operation. The segmented design enables the system to handle delicate fat tissue with precision.
Solution Approach 2:
The system integrates multiple functions into a single device that can harvest, wash, separate, and inject fat tissue. The universal design eliminates the need for multiple separate instruments, providing both ease of operation through a single integrated system and manufacturing precision through optimized functional components for each step of the process.
3Reliability
If conventional washing and treatment process is used, then tissue can be treated, but contamination risk increases and manual handling causes trauma to fat cells
Solution Approach 1:
The system creates a sterile, controlled environment (inert atmosphere) within the closed system where fat tissue is harvested and processed. This sterile environment prevents contamination from external sources, while the closed system minimizes mechanical trauma to fat cells by eliminating the need for manual handling and repeated transfers between containers.
Solution Approach 2:
The system replaces manual mechanical handling with an automated closed-system approach. Fat tissue is processed through the system without direct manual contact, eliminating mechanical trauma from manual handling. The washing and separation processes are performed automatically within the sterile field, reducing both contamination risk and cell damage.
4Productivity
If conventional centrifugation process is used, then fat can be separated from fluids, but the process must be performed outside sterile field requiring ancillary personnel
Solution Approach 1:
The system extracts the centrifugation function and replaces it with a filtration mechanism that operates within the sterile field. The filter component separates fat tissue from fluids through physical filtration rather than centrifugation, eliminating the need for external centrifugation equipment and ancillary personnel while maintaining separation efficiency.
Solution Approach 2:
The system uses a filter mechanism that replicates the separation function of centrifugation but operates within the sterile field. The filter copies the essential function of centrifugation (separating fat from fluids) while eliminating the need for complex centrifugation equipment and external processing, thereby reducing device complexity and improving productivity.
