Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If titanium mesh is used to support the regeneration membrane, then the membrane can be supported, but soft tissue grows into the through holes and adheres to the mesh, making it difficult to remove
Solution Approach 1:
The support device is divided into two functional parts: a mesh portion for supporting the regeneration membrane and a smooth support bar portion for easy removal. The mesh portion remains in place to provide structural support, while the smooth support bar can be easily extracted after healing, as tissue does not adhere to its smooth surface.
Solution Approach 2:
Different portions of the support device have different surface properties: the mesh portion has a porous structure that allows tissue integration and stability, while the support bar portion has a smooth surface that prevents tissue adherence and facilitates easy removal. This local differentiation of surface quality resolves the contradiction between stability and removability.
2Reliability
If titanium mesh with through holes is used, then the membrane can be supported, but the uneven surface and sharp edges may pierce the gum, leading to bone loss and infection
Solution Approach 1:
The device separates the supportive mesh function from the smooth support function. The mesh portion provides stability while the smooth support bar portion eliminates sharp edges that could pierce tissue, as the smooth surface is designed specifically to be tissue-friendly during the healing period.
Solution Approach 2:
The support bar portion has a specifically engineered smooth surface quality that contrasts with the mesh portion. This smooth surface prevents tissue adherence and eliminates sharp edges, locally addressing the tissue damage risk while maintaining overall support stability through the mesh structure.
3Area of stationary object
If multiple support devices are used for large defect areas, then adequate support is provided, but the operation becomes more complicated and inconvenient
Solution Approach 1:
The support device is designed as a universal component that can be applied to various defect sizes and locations. The mesh portion adapts to the defect area while the smooth support bar provides consistent support functionality, allowing the same device design to handle different coverage areas without increasing complexity.
Solution Approach 2:
The mesh portion and smooth support bar portion are combined into a single integrated device. This merging allows the device to function both as a support structure and as an easy-to-remove component, reducing the need for multiple separate devices and simplifying the overall procedure.
4Reliability
If long bone screws are used to support the membrane, then the membrane can be supported, but the limited fastening length in atrophied bone makes the screws unstable and prone to shaking
Solution Approach 1:
The device separates the support function (mesh portion) from the anchoring function (smooth support bar). The mesh portion provides the primary support for the membrane, reducing the burden on the anchored portion and allowing for greater overall stability even with limited fastening length in atrophied bone.
