Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing medication delivery pens face challenges in consistently and accurately disinfecting the septum and skin surface prior to injection, leading to potential misuse and increased risk of infection.
Innovation Solution
A cap equipped with a power source, light emitting source, and switch is designed to disinfect the skin surface and septum automatically, eliminating the need for alcohol swabs or antiseptic wipes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If alcohol swabs or antiseptic wipes are used to disinfect the skin surface and septum, then disinfection can be achieved, but user error increases and consistent accurate disinfection cannot be ensured
Solution Approach 1:
The cap is designed to automatically disinfect the septum and skin surface without requiring manual intervention with alcohol swabs or antiseptic wipes. The system self-services by integrating the disinfection function into the cap structure, eliminating user error and ensuring consistent accurate disinfection.
Solution Approach 2:
The cap performs disinfection as a preliminary action before the injection process. By integrating the disinfection function into the cap that is already attached to the medication delivery pen, the system ensures disinfection is completed automatically before use, eliminating the need for separate manual disinfection steps.
2Productivity
If manual disinfection with alcohol swabs or antiseptic wipes is required, then disinfection can be performed, but workflow efficiency decreases and user convenience is reduced
Solution Approach 1:
The cap combines multiple functions into a single integrated component: it serves as both the protective cap for the medication delivery pen and the disinfection device. By merging the cap and disinfection functions, the system eliminates separate disinfection steps and improves workflow efficiency without significantly increasing device complexity.
Solution Approach 2:
The cap is designed with multi-functionality, serving as both a protective cover and a disinfection device. This universal design allows the same component to perform multiple functions (protection and disinfection), thereby improving productivity while maintaining simplicity.
3Ease of operation
If separate alcohol swabs and antiseptic wipes are carried for disinfection, then disinfection can be performed, but user burden increases and convenience decreases
Solution Approach 1:
The invention extracts the disinfection function from separate external materials (alcohol swabs and antiseptic wipes) and integrates it directly into the cap structure. This eliminates the need to carry and manage multiple disinfection materials, reducing user burden and improving convenience.
Solution Approach 2:
The cap provides self-service disinfection, eliminating the need for users to manually apply alcohol swabs or antiseptic wipes. By integrating the disinfection function into the cap, the system reduces the quantity of external disinfection materials required and improves user convenience.
