Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for removing liquids from storage containers in the medical field, particularly in dental technology, face issues such as liquid spillage, contamination, complex operation, and difficulty in one-handed use, leading to increased risk of leakage and contamination, as well as challenging cleaning and maintenance due to complex designs with multiple parts.
Innovation Solution
A device with a body that connects to the storage container's opening, featuring a lateral syringe connection and a conical suction line that prevents spillage and contamination, allowing for one-handed operation and easy cleaning, with a detachable design and ventilation features to manage pressure differences and ensure secure connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a complex station with multiple parts and valves is used for liquid removal, then the liquid removal function is achieved, but the device complexity increases and cleaning becomes difficult
Solution Approach 1:
The device is divided into separate functional modules: a body component for connection to the storage container, a lid with rim for sealing, a suction line for liquid transport, and a connection interface for syringes. This segmentation allows each part to be optimized independently and simplifies cleaning by isolating liquid-contact areas.
Solution Approach 2:
The invention extracts the essential liquid removal function from complex station arrangements and concentrates it into a minimal device structure. By removing unnecessary valves, reservoirs, and intermediate components, the design achieves liquid removal through a direct suction line connection, eliminating cleaning difficulties associated with complex stations.
2Productivity
If the bottle is turned upside down for dispensing, then liquid flow is improved, but liquid spillage occurs
Solution Approach 1:
The device maintains the storage container in its original upright position while creating an equipotential flow path through the suction line. The suction mechanism draws liquid upward against gravity through the conical structure, eliminating the need to tilt or invert the container and preventing spillage from exposed openings.
3Reliability
If a Luer lock connector is used for syringe connection, then secure connection is achieved, but the connector is exposed and vulnerable to contamination
Solution Approach 1:
The Luer lock connector is nested within the lid structure, with the connection interface positioned inside the lid's internal cavity. This nesting protects the connector from external contamination while maintaining secure syringe attachment, as the connector remains enclosed during storage and operation.
Solution Approach 2:
The lid acts as an intermediary protective barrier between the external environment and the Luer lock connector. The lid's rim and internal structure create a sealed interface that allows secure connection while preventing direct exposure to contaminants, effectively mediating between connection security and contamination prevention.
4Reliability
If multiple valves and operating elements are used, then liquid control is improved, but one-handed operation becomes difficult
Solution Approach 1:
The invention extracts the liquid control function from multiple valves and operating elements, consolidating it into a single suction mechanism. The suction line with conical structure provides direct liquid removal control through one action, eliminating the need to manipulate multiple separate valves while maintaining reliable liquid control.
5Ease of repair
If the device has a detachable design for easy cleaning, then maintenance becomes simpler, but connection stability may be reduced
Solution Approach 1:
The device is segmented into detachable components including the body, lid, and suction line, allowing each part to be separated for cleaning. The segmentation includes connection interfaces designed for easy detachment while maintaining stable connections during operation, enabling simple maintenance without compromising connection reliability.
