Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional egg retrieval methods are used in in vitro fertilization, then the process can be performed with current technology, but the process is cumbersome and invasive requiring surgical extraction
Solution Approach 1:
The patent replaces the mechanical surgical extraction process with a biological differentiation approach. Instead of mechanically retrieving eggs through surgery, the invention uses transcription factor-based molecular mechanisms to guide stem cells to differentiate into germ cells, eliminating the need for invasive surgical procedures while achieving the same biological objective.
Solution Approach 2:
The patent changes the fundamental parameter of cell differentiation by using specific transcription factor combinations (such as SOX17, TFAP2C, and BLIMP1) to redirect stem cell development toward germ cell lineage. This molecular parameter change enables germ cell generation without requiring physical egg retrieval, transforming the process from mechanical to biochemical control.
2Reliability
If artificial ovulation stimulation is used to enhance egg retrieval, then egg retrieval success may improve, but the process becomes more complex and invasive
Solution Approach 1:
The patent substitutes artificial ovulation stimulation with direct stem cell differentiation protocols. Instead of using hormonal stimuli to trigger ovulation and then performing surgery, the invention directly manipulates stem cell differentiation through transcription factor expression, achieving reliable germ cell generation without the complex hormonal stimulation and surgical intervention required in traditional methods.
3Productivity
If surgical vaginal extraction is used for egg retrieval, then eggs can be obtained, but the process is invasive and time-consuming
Solution Approach 1:
The patent applies preliminary action by pre-differentiating stem cells into germ cell-like cells in the laboratory before any clinical procedure. This eliminates the need for time-consuming surgical retrieval by having the cells ready for transfer or study, significantly reducing the time required from egg retrieval to available cells.
Solution Approach 2:
The patent replaces the time-consuming surgical extraction process with an in vitro differentiation process that can be performed concurrently with other IVF procedures. By using molecular mechanisms to generate germ cells from stem cells in the laboratory, the invention eliminates the time required for surgical extraction while maintaining productivity.
4Reliability
If traditional IVF processes are used, then fertilization can occur, but failed retrievals due to follicular inadequacy or inadequate fertilization limit success
Solution Approach 1:
The patent applies preliminary action by pre-differentiating stem cells into germ cell-like cells with proper germ cell markers and chromosomal composition before fertilization attempts. This ensures that the cells are ready for fertilization regardless of follicular conditions, eliminating failures due to follicular inadequacy or inadequate fertilization.
Solution Approach 2:
The patent changes the fundamental parameter of cell origin from follicular eggs to differentiated stem cells. By controlling the differentiation process through transcription factors, the invention ensures consistent germ cell generation independent of follicular conditions, significantly improving reliability and adaptability to various patient conditions.
