Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If uncoated textile constructs made from synthetic polymers are used, then the implant is simple and easy to manufacture, but the bonding to bone is poor leading to fibrous tissue encapsulation and implant loosening
Solution Approach 1:
The patent applies composite materials by coating synthetic polymer textile constructs with bioactive ceramic particles. This creates a composite structure where the synthetic polymer provides mechanical properties and the bioactive ceramic particles enable bone bonding, thus resolving the contradiction between ease of manufacture and bonding reliability.
2Reliability
If bioactive ceramic coatings are applied to improve bone bonding, then the healing response is enhanced, but the coating consistency and adherence are poor leading to non-induction of expected biocompatible behavior
Solution Approach 1:
The patent employs parameter changes by optimizing coating parameters such as particle size distribution, coating thickness, and ceramic-to-polymer ratio to achieve consistent and homogeneous coatings. This resolves the contradiction between enhanced healing response and poor coating consistency.
Solution Approach 2:
The patent applies local quality by ensuring uniform distribution of bioactive ceramic particles throughout the coating layer, creating consistent local properties across the entire implant surface. This addresses the coating consistency issue while maintaining the enhanced healing response.
3Reliability
If a homogeneous bioceramic coating is achieved, then the osteointegration is improved, but the manufacturing process becomes more complex requiring quality control inspections
Solution Approach 1:
The patent applies preliminary action by establishing quality control inspection criteria before final product release. This includes pre-defining acceptance criteria for coating homogeneity and conducting inspections during manufacturing, thus achieving improved osteointegration while managing manufacturing complexity through proactive quality control.
