Hopper Unit Common Cover Element Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing reservoir units are cumbersome due to the need to individually open and close and lock multiple filling openings, which complicates the filling process.
Innovation Solution
Assigning a common cover element to multiple filling openings, with sealing elements interacting with the cover to simplify the opening and closing process, allowing all openings to be managed with a single cover element and ensuring reliable sealing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If each reservoir has its own filling opening with individual lid and locking elements, then each reservoir can be sealed independently, but the operation becomes cumbersome and complex
Solution Approach 1:
Multiple individual lids and locking elements are merged into a single common cover element that seals all filling openings simultaneously. This reduces the number of operational steps while maintaining sealing reliability through integrated sealing elements on the cover that interact with all reservoirs at once.
Solution Approach 2:
The common cover element serves multiple functions: it acts as a lid for all reservoirs, provides sealing through integrated sealing elements, and replaces multiple locking mechanisms with a single operational interface. This multi-functional design simplifies operation while ensuring reliable sealing of all reservoirs.
2Reliability
If multiple individual lids and locking elements are used for each filling opening, then each opening can be sealed independently, but the device complexity increases
Solution Approach 1:
Multiple separate lids and locking elements are combined into a single integrated common cover element. This consolidation reduces the total number of parts while maintaining sealing reliability through integrated sealing elements that interact with all filling openings simultaneously, thereby reducing device complexity.
Solution Approach 2:
The common cover element is designed as a universal component that performs the sealing function for all reservoirs through integrated sealing elements. This multi-functional design eliminates the need for multiple separate lids and locking mechanisms, significantly reducing device complexity while ensuring reliable sealing.
3Ease of operation
If a common cover element is used for all filling openings, then the operation is simplified and accessibility is enhanced, but the sealing complexity increases
Solution Approach 1:
The common cover element incorporates separate sealing elements for each filling opening, allowing independent sealing of each reservoir while maintaining a unified operational interface. This segmentation of sealing functions within the integrated cover simplifies operation while managing sealing complexity through modular sealing element design.
Solution Approach 2:
Multiple sealing elements are merged into the single common cover element structure, allowing all reservoirs to be sealed through one operational action. The integrated design combines multiple sealing functions into one component, simplifying operation while the internal segmentation of sealing elements manages the complexity of sealing multiple openings.

AI summary
The unit (1) has hopper reservoirs (3-5) comprising filler holes (6) lockable by cover units that are combined with a common cover element (7). Sealing elements (8) cooperative with the cover element are assigned to the filler holes. Individual filler holes are arranged next to each other such that the filler holes are separated from each other by bars (2). The hopper reservoirs are subjected to air pressure higher than atmospheric pressure by using a pressure conveyor system.
