Remover Body With Dual Gripping Sets For Needle Shield Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing medicament delivery devices require separate solutions for removing flexible and rigid needle shields, lacking a modular device that can handle both types effectively, which increases complexity and user risk during shield removal.
Innovation Solution
A device with a remover body featuring at least two sets of gripping members, one set for rigid and another for flexible needle shields, allowing for secure gripping and removal of various needle shields with reduced force requirements and enhanced safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate devices are used for removing flexible and rigid needle shields, then each device can be optimized for its specific shield type, but the overall device complexity increases and multiple solutions are required
Solution Approach 1:
The patent combines two separate shield removal mechanisms into a single integrated device. The remover body contains both a first set of gripping members for rigid shields and a second set of gripping members for flexible shields, allowing one device to handle multiple shield types that previously required separate solutions
Solution Approach 2:
The remover body is designed with universal functionality to accommodate different shield types. By incorporating multiple sets of gripping members with different configurations, the single device can universally remove both rigid and flexible needle shields, as well as other delivery member shields
2Device complexity
If manual pulling is used to remove needle shields, then the device structure remains simple, but user injury risk increases and discomfort occurs
Solution Approach 1:
The gripping members act as intermediary elements between the user and the needle shield. Instead of the user directly pulling the shield (which causes injury risk), the gripping members engage with the shield and provide a safe interface for removal, transferring the mechanical force through a controlled mechanism
Solution Approach 2:
The gripping members are designed to automatically engage with the shield during the removal process. The spring-loaded mechanism causes the gripping members to naturally contact and grip the shield when the remover body is positioned over it, eliminating the need for complex user manipulation
3Ease of manufacture
If a single remover body handles multiple shield types, then device complexity increases, but manufacturing and inventory management become more efficient
Solution Approach 1:
The gripping members are segmented into distinct sets (first set for rigid shields, second set for flexible shields) within the remover body. This segmentation allows each set to be optimized for its specific shield type while maintaining modular integration, making the device easier to manufacture and assemble
