Modular Implant Measuring Body Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for creating measuring bodies for implants require a new, single-piece fabrication for each implant shape, leading to high manufacturing costs and potential dimensional discrepancies due to the need for individual production processes and elaborate steps.
Innovation Solution
The measuring geometry is integrated into a separate inspection part, while the connecting geometry is on a supporting member, allowing the inspection part to be fabricated independently and the supporting member to be adapted for different implant shapes, reducing development and production efforts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a new single-piece measuring body is fabricated for each implant shape, then the measurement precision and fit accuracy are improved, but the manufacturing cost and production complexity increase significantly
Solution Approach 1:
The measuring body is divided into two separate components: a standardized inspection part with measuring geometry and a supporting member with connecting geometry. The inspection part can be reused across different implant types, while only the supporting member needs to be customized for each implant shape. This segmentation reduces manufacturing complexity and costs while maintaining measurement precision through the standardized inspection part.
2Manufacturing precision
If individual fabrication processes are used for each measuring body, then the measurement precision is maintained, but the production time and development effort increase
Solution Approach 1:
The inspection part is designed as a universal component that can be used with multiple implant types through standardized interfaces. The bearing and counter-bearing arrangement allows the same inspection part to accommodate different supporting members while maintaining measurement accuracy. This universality significantly reduces production time and development effort for new implant variations.
3Manufacturing precision
If elaborate production steps and individual patterns are created for each measuring body, then the manufacturing precision is achieved, but the device complexity and development resources increase
Solution Approach 1:
By separating the measuring body into inspection part and supporting member, the complex production process is simplified. The inspection part can be manufactured once with high precision using standardized patterns, while the supporting member can be produced separately for each implant type. This eliminates the need to create elaborate individual patterns for complete measuring bodies, reducing both device complexity and development resources.
