Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional systems for mixing chemicals with a diluent and dispensing the mixture lack an efficient mechanism for connecting a concentrated chemical container to an external diluent source, resulting in limited flexibility and control over the mixing process.
Innovation Solution
A fluid mixing and dispensing system that includes a body with flow passages and a container valve, allowing axial movement to control the flow of concentrate and diluent, utilizing venturi action to mix the chemicals, and preventing backflow, with attachment arms for secure engagement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional handheld device with separate chemical and diluent reservoirs is used, then mixing can be achieved, but the system lacks flexibility in connecting external diluent sources and has limited control over the mixing process
Solution Approach 1:
The mixing chamber is designed to serve multiple functions: it mixes concentrate with diluent from external sources, stores pre-mixed solution, and provides dispensing capability. This multi-functional design eliminates the need for separate reservoirs while maintaining mixing capability and enhancing flexibility.
Solution Approach 2:
The internal diluent reservoir is extracted from the system, replacing it with an external diluent source connection. This extraction simplifies the device structure while improving adaptability to various external diluent sources.
2Ease of operation
If axial movement of the body is used to control concentrate flow, then simple operation is achieved, but precise control over flow timing and amount is challenging
Solution Approach 1:
The system incorporates a flow regulator that responds to the axial movement of the body, automatically adjusting the concentrate flow rate and amount. This feedback mechanism translates simple axial movement into precise flow control without requiring complex user intervention.
Solution Approach 2:
The flow regulator and container valve work together to automatically control concentrate flow based on the body's axial position. The system self-regulates the mixing process, eliminating the need for manual flow control mechanisms.
3Productivity
If a container valve is used to regulate concentrate flow, then flow control is improved, but the risk of backflow and contamination increases
Solution Approach 1:
The check valve is positioned to utilize the natural flow direction of concentrate from the container. It converts the potential harm of uncontrolled flow into a benefit by preventing backflow while maintaining efficient forward flow regulation through the container valve.
Solution Approach 2:
The check valve provides preliminary protection against backflow before it can cause contamination. By placing the check valve at the outlet of the container, it preemptively blocks any reverse flow path.
4Reliability
If secure attachment mechanisms are used to prevent accidental disconnection, then system reliability is improved, but the ease of attachment and removal decreases
Solution Approach 1:
The attachment mechanism is segmented into distinct components: attachment arms with engagement features on one side, and corresponding receptacles on the other. This segmentation allows for simple alignment and engagement while maintaining secure connection.
Solution Approach 2:
The attachment mechanism incorporates dynamic elements that allow easy engagement through axial movement but provide secure locking once attached. The design transitions from a simple approach state to a locked secure state, maintaining ease of operation while ensuring reliability.
