Expandable Feed Element Sealing for Viscous Cavity Filling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing component systems require complex assembly and additional mechanical closure means to fix the feed element during the filling of cavities with viscous liquids, increasing the time and complexity of the filling process.
Innovation Solution
A component system with an elastically expandable or bayonet-style closure and sealing element that transitions between closure and release positions, allowing for easy and reliable filling without additional fixation or sealing means, using an elastomeric body or balloon catheter design to secure the feed element within the cavity during filling and release it afterward.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If mechanical fixations and additional closure means are used to fill cavities with highly viscous liquids, then the filling can be performed reliably, but the assembly time and device complexity increase
Solution Approach 1:
The closure element combines multiple functions into a single integrated component: it provides sealing against the feed opening, mechanically secures the feed element against filling pressure, and enables controlled removal. This merging eliminates the need for separate mechanical fixations and closure means, reducing assembly complexity while maintaining filling reliability
Solution Approach 2:
The closure element transitions between different states (open/closed, secured/released) based on the filling process requirements. During filling, it dynamically secures the feed element against high injection pressure, and after filling, it can be dynamically removed. This dynamic behavior replaces static complex mechanical fixations
2Productivity
If high injection pressure is used to fill narrow cavities with highly viscous liquids, then the filling can be completed, but the feed element must be mechanically fixed to withstand the counteracting pressure
Solution Approach 1:
The closure element merges the functions of pressure resistance and mechanical fixation into a single component. It directly withstands the filling pressure that acts counter to the direction of introduction while simultaneously securing the feed element in position, eliminating the need for separate mechanical fixation systems
Solution Approach 2:
The closure element is designed to automatically withstand and respond to the filling pressure without requiring additional external fixation mechanisms. The single closure element self-sufficiently handles the pressure load and secures the feed element, simplifying the overall system
3Strength
If additional mechanical closure means are used to secure the feed element, then the feed element can be held against filling pressure, but the assembly and disassembly time increase
Solution Approach 1:
The closure element combines pressure resistance and positioning functions into one component, eliminating the need for multiple separate mechanical closure elements. This reduction in component count directly reduces assembly and disassembly time while maintaining the necessary strength to withstand filling pressure
Solution Approach 2:
The invention extracts and eliminates unnecessary intermediate mechanical fixation components from the system. The single closure element directly performs the securing function without requiring additional mechanical closure means, thereby reducing assembly complexity and time

AI summary
A component system including at least two components, between which a cavity to be filled is formed, wherein the cavity has a feed section, and a filling device for the filling of the cavity via a feed element, which can be introduced, before the filling procedure into the feed section. The feed element has a closure and sealing element, which is configured to close and seal the feed section in a closure position during the filling procedure. The closure and sealing element is configured as an elastically expandable body, which can change between the closure position and a release position. During an introduction of the feed element into the feed section, the closure and sealing element is in the release position, and can then be transferred into the closure position.
