Fluid Dispensing Apparatus With Rotational Locking Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fluid dispensing apparatuses for body cavities, such as enema devices, face challenges with difficult-to-open and fill bulbs or bags, and often require disposal or reuse, lacking efficient and hygienic solutions for fluid delivery and containment.
Innovation Solution
A fluid dispensing apparatus comprising a fluid container assembly, cap member, and tip member with a one-way valve assembly, O-rings for sealing, and a locking mechanism that allows for easy attachment and detachment of components, enabling secure and hygienic fluid delivery to body cavities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional bulbs or bags are used for fluid dispensing, then fluid containment is achieved, but opening and filling becomes difficult
Solution Approach 1:
The device is divided into separate components: a reusable fluid container assembly and replaceable tip members. This segmentation allows the tip member to be easily opened and filled by simply removing the cap, while the main container provides structural support and fluid storage.
Solution Approach 2:
The tip member is designed to be inserted into and nested within the cap, which itself attaches to the fluid container. This nested structure allows compact storage while maintaining easy access to the filling opening through the cap removal mechanism.
2Reliability
If disposable tip members are used, then hygiene is improved, but device complexity increases due to multiple components
Solution Approach 1:
The tip member is designed as a disposable component that can be easily attached and removed. After use, the entire tip member is discarded, eliminating the need for cleaning and sterilization processes, thereby ensuring hygiene while keeping the overall system simple.
Solution Approach 2:
The cap and tip member are designed to work together as an integrated assembly during use, with the cap providing both sealing and attachment functions. This merging reduces the number of separate components needed while maintaining hygiene through disposable tip members.
3Reliability
If secure attachment mechanisms are used, then fluid delivery security is improved, but ease of operation decreases
Solution Approach 1:
The attachment mechanism uses a dynamic locking system where the cap rotates to engage locking tabs with corresponding slots in the fluid container. This provides secure attachment during use while allowing easy detachment by simply rotating the cap in the opposite direction.
Solution Approach 2:
The locking mechanism replaces complex mechanical fastening systems with a simple rotational locking action. The locking tabs and slots provide secure attachment through geometric interlocking, while the rotational motion provides user-friendly operation without requiring tools or complex maneuvers.

AI summary
A fluid dispensing apparatus for irrigating a body cavity includes a fluid container assembly, a cap member, and a tip member. The fluid container assembly defines a longitudinal axis and includes a fluid container and an inlet assembly fixedly secured to the fluid container. The cap member is selectively rotatably attached to the inlet assembly. The tip member is selectively attachable to the cap member in response to rotation of the tip member about the longitudinal axis of the fluid container assembly.
