Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dischargers for medical, dental, or veterinary agents are often costly and environmentally unfriendly, requiring high material consumption and complex cleaning processes, while also posing challenges in user friendliness and safety, especially for single-use disposable syringes.
Innovation Solution
A discharger design featuring a breakable section that allows for easy and reliable fluid discharge from a separate container, utilizing a proximal and distal portion interconnected by a breakable section, which can be broken with minimal force, ensuring child safety and reducing material usage through a separate container system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If disposable dischargers are used to avoid spreading infectious diseases and eliminate cleaning processes, then patient safety and operational simplicity are improved, but material consumption and environmental impact increase
Solution Approach 1:
The discharger is divided into a reusable discharge section and a disposable intermediate section with separate container. This segmentation allows the expensive and environmentally impactful components (discharge section and container) to be separated, enabling reuse of the discharge section while discarding only the necessary disposable parts, thus reducing overall material consumption while maintaining patient safety.
Solution Approach 2:
The design enables recovery and reuse of the discharge section while discarding the intermediate section with container. The discharge section can be sterilized and reused across multiple patients, eliminating the need to discard the entire discharger assembly, thereby reducing material consumption and environmental impact while maintaining reliability through proper sterilization protocols.
2Reliability
If high material consumption is used to ensure reliable fluid discharge, then discharge reliability is improved, but production cost and environmental friendliness worsen
Solution Approach 1:
By segmenting the discharger into reusable and disposable parts, the design reduces material consumption in the reusable discharge section while maintaining discharge reliability through proper engineering of the discharge passage and activation mechanism. The disposable intermediate section uses minimal material only where necessary, reducing overall production cost while ensuring reliable fluid discharge.
3Ease of operation
If a breakable section is added to enable easy opening, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The breakable section is designed with specific local properties (weaker material, predetermined break point) at a localized position in the intermediate section. This localized modification enables easy opening at a specific location without requiring complex mechanisms throughout the entire device, maintaining overall structural simplicity while improving ease of operation.
Solution Approach 2:
The breakable section is pre-designed with a predetermined breaking point during manufacturing, so that when the user applies force during activation, the section breaks at the intended location. This preliminary preparation of the breaking point eliminates the need for complex opening mechanisms, reducing device complexity while ensuring easy and reliable activation.
4Loss of substance
If separate container system is used to reduce material usage, then environmental friendliness is improved, but reliability of fluid discharge may worsen
Solution Approach 1:
The intermediate section serves as a merging point that combines the separate container with the discharge section through the breakable section. This merging ensures reliable fluid discharge by creating a sealed connection between the container and discharge passage, while the separate container design reduces material consumption. The breakable section maintains sealing integrity until activation, ensuring reliable discharge.
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
The design enables cost-effective, environmentally friendly production of dischargers with reduced material consumption, ensuring easy and reliable operation while maintaining user safety and preventing unintentional discharge, particularly suitable for medical and veterinary applications.
Implementation Method 1
The breakable section of the intermediate section preferably can comprise a predetermined breaking area or breaking point adapted to break upon applying an axial force to the intermediate section, in particular along the longitudinal axis
Implementation Method 2
When applying a force the tearable film can stretch to a limited extent until it finally breaks

AI summary
A discharger for discharging a predetermined amount of fluid from a separate container including a discharge section defining a longitudinal axis and having a proximal end and a distal end and having a discharge passage for the fluid extending between an inlet opening and an outlet opening of the discharge section. The discharger further includes an intermediate section including a distal portion cooperating with the proximal end of the discharge section and a proximal portion defining a receiving space which is adapted to be loaded with the separate container holding an amount of fluid to be discharged by the discharger. The distal portion and the proximal portion are formed in one piece and are interconnected by a breakable section.
