Pre-fillable Syringe Replacement Cap Integration

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Pre-filled syringes with small tip caps are inconvenient for users to handle, leading to difficulties in setting dosages and potential air introduction during reclosure, which can cause patient irritation, especially with high-viscosity mediums.

Innovation Solution

A system that includes a pre-fillable syringe with a tip cap and a replacement cap integrated into the package, allowing for easy retrieval and mounting of the replacement cap without needing additional packaging, facilitating one-handed operation and reducing the risk of contamination.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Volume of moving object

If the tip cap is made small to fit limited space in the syringe nest, then the space utilization is improved, but the ease of handling and operation deteriorates

Engineering Contradiction:

Improvetip cap sizeVSAvoidhandling convenience

Core Design Contradiction:

Volume of moving objectVSEase of operation

Solution Approach 1:

The replacement cap is pre-positioned inside the package body alongside the syringe, ready for immediate use. This preliminary preparation eliminates the need for users to search for or retrieve a separate cap, significantly improving handling convenience while maintaining a compact overall package design.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The replacement cap is integrated into the same package body as the syringe, combining multiple functions (syringe storage and cap storage) into a single unified package. This merging approach improves ease of operation by ensuring the cap is always available with the syringe, while the compact integration maintains space efficiency.

Inventive Principle:

Principle #5Merging (Combining)

2Adaptability or versatility

If the tip cap is removed for dosage setting and reclosed, then the dosage adjustment capability is improved, but the risk of air introduction and contamination increases

Engineering Contradiction:

Improvedosage setting capabilityVSAvoidair introduction and contamination

Core Design Contradiction:

Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The replacement cap is prepared and positioned in advance within the package body, ready for immediate replacement after tip cap removal. This ensures that users can quickly reclose the syringe with a clean, pre-positioned cap, minimizing the time the syringe is open and reducing the risk of air introduction and contamination while maintaining dosage adjustability.

Inventive Principle:

Principle #10Preliminary action

3Adaptability or versatility

If additional packaging is provided for the replacement cap, then the availability of replacement cap is improved, but the device complexity and package size increases

Engineering Contradiction:

Improvereplacement cap availabilityVSAvoidpackage structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The replacement cap is merged with the main package body, eliminating the need for separate additional packaging. The cap is positioned within the same package cavity or compartment as the syringe, ensuring availability while maintaining a simple, integrated package structure without increasing overall complexity.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The replacement cap is nested within the package body, utilizing the existing package space efficiently. This nesting approach ensures the cap is always available with the syringe while avoiding the need for separate outer packaging or complex multi-layer package structures.

Inventive Principle:

Principle #7Nested doll (Nesting)
