Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing component systems require complex and time-consuming assembly processes to fill cavities with highly viscous liquids, often necessitating additional mechanical locking means to secure the feed element against filling pressure.
Innovation Solution
A component system featuring an elastically expandable closure and sealing element that switches between a closed and release position, providing a sealing and blocking mechanism without the need for additional fixing or sealing means, using a high adhesive contact to secure the feed element during filling and releasing it post-filling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a feed element is used to introduce highly viscous liquid into a narrow cavity, then the filling process can be performed, but the feed element requires mechanical fixation to withstand the injection pressure
Solution Approach 1:
The closure and sealing element changes its physical state from compressed (during insertion) to expanded (during sealing), altering its dimensional parameters to achieve the sealing function. This parameter change eliminates the need for complex mechanical locking devices while reliably securing the feed element against filling pressure.
Solution Approach 2:
The closure and sealing element is designed as a dynamic component that transitions between different states (compressed and expanded) based on the filling process stage. This dynamic behavior allows the same component to serve multiple functions: enabling insertion during compression and providing sealing/fixation during expansion, thereby simplifying the overall device structure.
2Reliability
If complex mechanical locking devices are used to secure the feed element, then the feed element can withstand filling pressure, but the assembly time increases
Solution Approach 1:
The closure and sealing element performs self-service by automatically transitioning to its expanded sealing state upon insertion into the feed section. This self-activating mechanism eliminates the need for separate locking operations, significantly reducing assembly time while maintaining reliable fixation against filling pressure.
Solution Approach 2:
The invention extracts the locking function from separate mechanical devices and integrates it into the closure and sealing element itself. By combining the sealing and fixation functions into a single component that activates automatically, the assembly process is streamlined and time is reduced.
3Reliability
If the feed element is securely fixed during filling, then the sealing is reliable, but the removal of the feed element becomes difficult
Solution Approach 1:
The closure and sealing element is designed as a dynamic component that can transition between expanded (sealing/fixation) and compressed (removal-friendly) states. During filling, it expands to provide reliable sealing and fixation. After filling, it can be compressed to release the fixation, enabling easy removal of the feed element without compromising the sealing reliability during the filling process.
