Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual bonding procedures are used to attach prosthetic teeth to the prosthesis base, then flexibility in adjustment is improved, but manufacturing precision and reliability deteriorate due to uneven adhesive application and potential aesthetic impairments
Solution Approach 1:
The patent replaces the manual mechanical bonding process with an automated adhesive application system that precisely controls adhesive deposition. The system uses computer-controlled mechanisms to apply adhesive uniformly to the prosthesis base, eliminating the variability and imprecision of manual bonding while maintaining the ability to adjust tooth positions through digital modeling and automated positioning mechanisms.
2Adaptability or versatility
If complex bonding and joining techniques are used to produce multicolored dentures or dentures made of different polymer materials, then product versatility is improved, but device complexity and manufacturing precision deteriorate
Solution Approach 1:
The patent divides the prosthesis into separate modular components including the prosthesis base, prosthetic teeth, and retaining structures that can be manufactured independently using different materials and colors. This segmentation allows each component to be optimized separately and assembled through automated mechanisms, reducing the complexity of producing multicolored and multi-material dentures while maintaining high versatility.
Solution Approach 2:
The patent employs universal retaining structures and standardized interfaces that can accommodate different material combinations and color schemes. The automated assembly system is designed to handle various material types and configurations through programmable mechanisms, enabling the same device to produce diverse prosthesis variations without requiring complex specialized equipment for each configuration.
3Adaptability or versatility
If manual processing and adjustment of prosthetic teeth are performed, then adaptability to individual patient needs is improved, but productivity and manufacturing precision deteriorate
Solution Approach 1:
The patent performs preliminary digital planning and virtual positioning of prosthetic teeth before physical manufacturing. The system uses digital models to pre-determine the optimal arrangement, occlusion, and positioning of teeth based on patient-specific requirements. This preliminary digital action allows for rapid customization without time-consuming manual adjustments during production, significantly improving productivity while maintaining high adaptability to individual patient needs.
4Ease of operation
If adhesive is applied manually to bond prosthetic teeth, then ease of operation is improved, but manufacturing precision and reliability deteriorate due to uneven application and aesthetic impairments
Solution Approach 1:
The patent replaces manual adhesive application with an automated dispensing system that precisely controls the amount, location, and uniformity of adhesive application. The computer-controlled mechanism ensures consistent bonding reliability by eliminating human variability in adhesive deposition, while the system remains easy to operate through automated sequences and programmable parameters that simplify the bonding process.
