Closure Drainage System for Fluid Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing closures with multiple components face challenges in preventing the ingress of water between the body and insert parts, leading to fluid trapping, which is undesirable during manufacturing processes like cooling or cleaning.
Innovation Solution
A closure design incorporating a drainage system with drainage paths at the interface between the insert and body, featuring slots and radial projections, allows fluid to pass through and be removed, ensuring effective drainage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If closures are designed with multiple components (body and insert), then functionality and versatility are improved, but fluid ingress between components occurs causing harmful fluid trapping
Solution Approach 1:
The drainage system is segmented into multiple drainage paths distributed around the interface between the insert and body. This segmentation allows fluid to escape through multiple locations rather than relying on a single drainage point, effectively preventing fluid trapping while maintaining the multi-component closure structure.
Solution Approach 2:
The drainage paths act as an intermediary structure between the insert and body components. These paths provide a controlled interface that allows fluid to pass through from the exterior to the interior of the closure, preventing harmful fluid accumulation while maintaining the functional integrity of the multi-component design.
2Reliability
If drainage paths are formed at the interface between insert and body, then fluid drainage is improved, but manufacturing complexity increases
Solution Approach 1:
The drainage paths are merged with the existing interface structure between the insert and body. Rather than adding separate drainage components, the drainage functionality is integrated into the mating surfaces of the insert and body, forming drainage channels as part of the interface geometry itself. This reduces manufacturing complexity while ensuring reliable fluid drainage.
Solution Approach 2:
The interface between the insert and body serves multiple functions: it provides structural connection, sealing, and fluid drainage. The drainage paths are formed as part of this universal interface structure, allowing the same components to fulfill multiple roles without increasing overall device complexity.
3Productivity
If slots are formed between ribs at the periphery of insert, then drainage efficiency is improved, but manufacturing precision requirements increase
Solution Approach 1:
The drainage slots are located at specific local positions between the ribs at the periphery of the insert. This local placement optimizes drainage efficiency by positioning openings where fluid naturally accumulates and flows. The slots are formed only where needed rather than throughout the entire structure, reducing manufacturing precision requirements to localized areas.
Solution Approach 2:
The ribs and slots are designed with curved or inclined surfaces that facilitate fluid flow toward the drainage paths. The inclined drainage faces of the ribs guide fluid downward into the slots, improving drainage efficiency while allowing for simpler manufacturing of the curved surfaces compared to precise angular features.
