Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In surgical procedures for implanting prostheses, there is a challenge in efficiently and accurately matching the correct size of instruments with the corresponding prosthetic members to ensure proper implantation and minimize post-implantation complications such as micromotion and wear.
Innovation Solution
Color coding prosthetic components and related instruments using anodizing, where each size of prosthesis and its coordinating instruments are marked with a unique color, ensuring visual identification and compatibility, with the option to also use laser etching or different materials like titanium or stainless steel for biocompatibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If color coding is applied to prosthetic components and instruments, then identification accuracy and matching precision are improved, but manufacturing complexity increases due to additional anodizing or laser etching processes
Solution Approach 1:
The patent applies color coding to prosthetic components and instruments through anodizing or laser etching processes. Different colors are assigned to different sizes and types of components (e.g., blue for 50mm acetabular cup, red for 60mm) to enable rapid visual identification and correct matching during surgical procedures, thereby improving identification accuracy despite adding manufacturing steps.
2Reliability
If multiple identification methods (color coding, laser etching, material selection) are used, then reliability of component matching is improved, but ease of manufacture deteriorates due to more processing options
Solution Approach 1:
The patent implements multiple identification methods at different locations and levels: color coding through anodizing or laser etching on the surface, material selection (titanium or stainless steel), and size-specific instrumentation. These localized quality enhancements provide redundant identification cues that improve reliability of component matching while allowing manufacturers to choose from multiple processing options.
3Productivity
If visual identification systems are implemented, then speed of procedure is improved through faster component selection, but device complexity increases due to additional coding systems
Solution Approach 1:
The patent implements a color-coded visual identification system where different colors represent different sizes and types of prosthetic components and instruments. This allows surgical teams to rapidly identify and select the correct components during procedures without requiring detailed examination of specifications, thereby increasing procedural speed despite the added complexity of the coding system.
