Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bone plating systems lack flexibility in providing both locking and non-locking capabilities for dynamic compression, which is essential for effective bone stabilization, especially in complex fractures.
Innovation Solution
The development of bone stabilization systems that include plates with combination openings for both locking and non-locking fasteners, allowing for dynamic compression and interfragmental compression, using textured and smooth surfaces to secure the fasteners to the plate, enabling both fixed and variable angle locking and non-locking options.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If locking fasteners are used to secure the plate to the bone, then the stability and fixed angle locking is improved, but the ability to provide dynamic compression is reduced
Solution Approach 1:
The opening is segmented into multiple functional zones: a textured portion for locking engagement and a smooth portion for dynamic compression. This segmentation allows the single opening to accommodate both locking and non-locking fasteners, resolving the contradiction between stability and adaptability.
Solution Approach 2:
The opening is designed with multi-functionality to serve both locking and non-locking purposes. By incorporating both textured and smooth portions within the same opening, the structure can universally accept different types of fasteners (locking or non-locking) depending on the surgical requirement, thus achieving both stability and dynamic compression capability.
2Adaptability or versatility
If non-locking fasteners are used to provide dynamic compression, then the adaptability and compression capability is improved, but the stability and fixed angle locking is reduced
Solution Approach 1:
The opening is divided into distinct functional regions where the smooth portion enables non-locking fastener insertion for dynamic compression, while the textured portion provides locking engagement when needed. This spatial segmentation resolves the contradiction by allowing each fastener type to engage with its optimal surface portion.
Solution Approach 2:
The opening structure is designed to be universal, accommodating both locking and non-locking fasteners through its dual-texture design. The smooth portion facilitates compression while the textured portion ensures stability, making the same opening adaptable to different surgical needs without compromising either compression or stability.
3Reliability
If the opening has a textured surface for locking engagement, then the locking capability is improved, but the ease of insertion for non-locking fasteners is reduced
Solution Approach 1:
The opening surface is segmented into textured and smooth zones. The smooth portion provides ease of insertion for non-locking fasteners by reducing friction, while the textured portion ensures reliable locking engagement when locking fasteners are used. This segmentation resolves the contradiction between locking reliability and insertion ease.
Solution Approach 2:
Different portions of the opening have different surface qualities tailored to specific functions. The smooth portion locally optimizes for insertion ease, while the textured portion locally optimizes for locking reliability. This local differentiation resolves the contradiction by providing each quality where it is most needed.
4Ease of operation
If the opening has a smooth surface for easy insertion, then the ease of operation is improved, but the locking capability is reduced
Solution Approach 1:
The opening is segmented to include both smooth and textured portions. The smooth portion facilitates easy insertion of non-locking fasteners, while the textured portion provides reliable locking engagement for locking fasteners. This segmentation resolves the contradiction between ease of operation and locking capability.
Solution Approach 2:
The opening structure applies different surface qualities at different locations: smooth surface locally for insertion ease and textured surface locally for locking reliability. This local quality differentiation resolves the contradiction by ensuring each function has its optimal surface condition.
