Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If a mechanical support (prosthesis, implant) is used to maintain the biological matrix in three dimensions, then the biological matrix can be maintained in three dimensions, but the device complexity increases and mechanical integrity is compromised
Solution Approach 1:
The patent removes the mechanical support (prosthesis, implant) from the system by using a polymer coating that directly maintains the biological matrix in three dimensions. The polymer layer is applied to the biological matrix elements and assembled into a three-dimensional structure without requiring an additional mechanical support framework, thereby simplifying the device while maintaining the desired shape.
Solution Approach 2:
The patent creates a composite structure by combining biological matrix elements with a polymer coating. The polymer material is applied to the biological matrix and cured to form an integrated composite structure that maintains three-dimensional shape without requiring separate mechanical support. This composite approach eliminates the need for additional prosthesis or implant components.
2Shape
If the acellular biological matrix is perforated or elements are cut out to assemble by suturing or gluing, then the three-dimensional shape can be achieved, but the manufacturing complexity and time increase
Solution Approach 1:
The patent applies the polymer coating to the biological matrix elements before assembly into the three-dimensional structure. This preliminary coating action creates a bonding interface that facilitates subsequent assembly without requiring complex perforation, cutting, suturing, or gluing operations. The polymer is applied in advance to prepare the surface for easy assembly, thereby improving manufacturing efficiency.
Solution Approach 2:
The patent combines the shape-maintaining function and the assembly function into a single polymer coating layer. Instead of separately perforating the matrix, cutting elements, and then assembling them with sutures or glue, the polymer coating is applied to the biological matrix elements and then the elements are assembled into the three-dimensional structure. This merging of functions simplifies the manufacturing process and improves productivity.
3Reliability
If the acellular biological matrix is used alone for flat medical devices, then the biological compatibility is maintained, but the mechanical resistance and flexibility are insufficient for three-dimensional applications
Solution Approach 1:
The patent creates a composite structure by combining biological matrix elements with a polymer coating. The polymer material is applied to the biological matrix and cured to form an integrated composite structure that maintains three-dimensional shape without requiring separate mechanical support. This composite approach eliminates the need for additional prosthesis or implant components.
4Strength
If polymer coating is applied to the biological matrix elements, then the mechanical resistance and infection resistance are improved, but the manufacturing steps increase
Solution Approach 1:
The patent changes the physical and chemical parameters of the polymer coating to optimize its performance. The polymer is selected and formulated to provide the desired mechanical resistance, flexibility, and infection resistance properties. By carefully controlling the polymer parameters (composition, thickness, curing conditions), the manufacturing process is simplified while achieving the desired performance enhancement.
