Adjustable Insertion Tool for Variable Cannula Depth
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing insertion systems for medical devices, such as analyte sensors, require significant redesign and long production times to adjust the length of the insertion cannula based on medical studies, leading to delays and increased costs.
Innovation Solution
An insertion tool with an adjustable second end allows for quick and easy adjustment of the insertion cannula length without requiring redesign of production tools, enabling efficient and cost-effective production.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the insertion cannula length is adjusted based on medical studies, then the safety and effectiveness of the medical device is improved, but the production time and cost increase significantly due to redesign requirements
Solution Approach 1:
The shaft is designed with an adjustable second end that can be configured to different lengths through simple modifications such as cutting or removing portions, rather than requiring complete redesign. This dynamic adjustability allows the insertion tool to adapt to different medical study requirements while maintaining efficient production processes.
Solution Approach 2:
The shaft is divided into segments where the second end can be independently adjusted or removed. This segmentation allows for easy modification of the insertion cannula length by simply cutting or detaching the adjustable portion, eliminating the need for complex redesign of the entire production tooling.
2Reliability
If the insertion cannula length is adjusted based on medical studies, then the safety and effectiveness of the medical device is improved, but the production cost increases due to redesign requirements
Solution Approach 1:
The adjustable second end allows the shaft to be modified through simple, low-cost operations such as cutting or removing material, rather than requiring expensive redesign of the entire production tooling. This reduces the cost impact of adapting to new medical study findings.
Solution Approach 2:
The length parameter of the shaft can be easily changed by modifying the second end through cutting or removal operations. This simple parameter adjustment avoids the need for costly redesign and retooling, making the manufacturing process more cost-effective while still allowing adaptation to different medical requirements.
3Ease of manufacture
If a fixed mechanical stop is used to attach the insertion cannula, then the manufacturing process is simple, but the adaptability to different insertion depth requirements is limited
Solution Approach 1:
The mechanical stop is replaced with an adjustable second end that can be dynamically configured to different lengths. This allows the insertion tool to adapt to various insertion depth requirements while maintaining a relatively simple manufacturing process that doesn't require complex adjustable mechanisms.
Solution Approach 2:
The fixed mechanical stop is removed and replaced with an adjustable second end that can be cut or removed to different lengths. This extraction of the fixed constraint allows for greater adaptability while keeping the overall manufacturing process simple.
