Adjustable Spring Force Fluid Dispenser
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fluid dispensers use a single spring force for all fluids, which may not be suitable for different fluids, and allow the use of incompatible fluid containers, leading to inefficiencies and potential misuse.
Innovation Solution
A spring biased activation unit where the spring force can be adjusted by varying the distance between its ends, using interchangeable spring seat members to change the deflection extent, ensuring appropriate force for different fluids and preventing unauthorized use of incompatible containers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single spring force is used for all fluids, then the device structure is simple, but the dispensing performance is inadequate for different fluids
Solution Approach 1:
The spring seat member is made movable along the longitudinal axis of the spring, allowing the deflection distance and spring force to be dynamically adjusted. This enables the same spring to provide different forces for different fluids by simply repositioning the spring seat member, resolving the contradiction between adaptability and device complexity
Solution Approach 2:
The invention changes the physical parameter of spring deflection distance by allowing the spring seat member to be positioned at different locations along the spring's longitudinal axis. This parameter change enables the spring force to be adjusted for different fluids without changing the spring itself, achieving adaptability while maintaining structural simplicity
2Reliability
If any fluid container is permitted, then the dispenser is versatile, but incompatible containers may be used leading to misuse
Solution Approach 1:
The spring seat member incorporates specific engagement features (such as engagement protrusions and corresponding recesses) that create a localized quality requirement for container compatibility. Only containers with matching features can properly engage the spring seat member, ensuring reliable operation while preventing misuse of incompatible containers
Solution Approach 2:
The spring seat member acts as an intermediary component between the spring and the fluid container. It provides a standardized interface that mediates the interaction, ensuring that only compatible containers can be properly installed and used, thus preventing misuse while maintaining versatility
3Ease of operation
If the spring deflection distance is fixed, then the device structure is simple, but the spring force cannot be optimized for different operations
Solution Approach 1:
The spring seat member is designed to be movable along the spring's longitudinal axis, transforming the fixed deflection distance into a dynamic, adjustable parameter. This allows the spring force to be optimized for different operational requirements by simply repositioning the spring seat member, improving ease of operation while adding minimal structural complexity
Solution Approach 2:
The spring seat member can be pre-positioned at optimal locations for different fluid types and operational conditions. This preliminary action of setting the spring force before use allows for optimized performance without requiring complex real-time adjustment mechanisms during operation
