Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face challenges in accessing the desired amount of chemically unstable filling compounds without complex warehousing or compliance with costly safety regulations, especially when needing small or irregular amounts, leading to inefficiencies and waste due to pre-filled syringes with specified volumes.
Innovation Solution
A syringe design with two sub-chambers for separate components, connected to a cartridge via tubular connectors, allowing for precise filling and mixing, with a mixer and transparent housing for visual fill level monitoring, enabling partial filling and reducing waste by using a cartridge with multiple times the syringe's volume for efficient use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If pre-filled syringes with specified volumes are used, then the user has the filling material available immediately, but the user cannot adjust the fill volume for different application requirements
Solution Approach 1:
The syringe reservoir is divided into multiple separate compartments, each containing a different flowable component. This segmentation allows the user to fill only the compartments needed for their specific application, enabling both immediate availability and volume adjustability by selecting and filling appropriate compartments.
Solution Approach 2:
The syringe system transitions from a static pre-filled configuration to a dynamic fillable system where compartments can be selectively filled based on application requirements. The dual-nozzle docking element enables flexible filling operations, allowing the system to adapt to different fill volume needs while maintaining ease of operation.
2Ease of operation
If a reservoir of filling material is kept on hand for immediate filling, then the user can fill syringes as needed, but the user must comply with costly safety regulations and storage facilities for hazardous materials
Solution Approach 1:
The filling material is extracted from the syringe and placed in separate, secure compartments within the reservoir. This extraction allows the material to be stored safely in a compact form, eliminating the need for expensive storage facilities and safety regulations while maintaining the ability to fill syringes as needed.
Solution Approach 2:
The syringe is designed as a disposable unit with compartments that can be filled and then discarded after use. This eliminates the need for permanent storage facilities and safety infrastructure, as each syringe is a self-contained, single-use unit that doesn't require ongoing compliance with hazardous material storage regulations.
3Device complexity
If pre-filled syringes are used, then the user avoids storage and safety compliance costs, but the user experiences waste when needing smaller or irregular amounts of filling material
Solution Approach 1:
Each compartment in the reservoir is designed with specific capacity and is filled selectively based on the local requirement of the application. This local quality approach allows the user to fill only the compartments needed for their specific task, preventing waste while avoiding storage compliance costs through the disposable nature of the syringe.
Solution Approach 2:
The system allows partial filling of compartments rather than requiring full pre-filled syringes. The user can fill only the necessary amount of material into the appropriate compartments, using partial action to avoid waste while maintaining the simplicity of the disposable syringe system without storage compliance requirements.
4Adaptability or versatility
If multiple pre-filled syringes with varying volumes are kept in stock, then the user can meet different application requirements, but the user faces increased storage space requirements and faster expiration of chemically unstable materials
Solution Approach 1:
The reservoir is segmented into multiple compartments that can be filled with different volumes of flowable components based on application requirements. This segmentation allows the user to store multiple configurations in a single compact unit, reducing storage space while maintaining versatility and preventing material expiration through controlled access.
Solution Approach 2:
The system allows preliminary filling of compartments with different volumes before use. The user can prepare the syringe with the exact volumes needed for different applications in advance, eliminating the need to store multiple pre-filled syringes and reducing both storage space requirements and material expiration risks.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables users to have the desired amount of filling compound available with reduced storage needs and compliance costs, minimizing waste by allowing precise filling and efficient use of chemically unstable materials, particularly beneficial for small or irregular needs.
Implementation Method 1
The first and second pistons are movable by means of a plunger to discharge the two components simultaneously. The first and second pistons are movable by means of a plunger under pressure in such a way that the filling volume in each of the first and second sub-chambers decreases.
