Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pneumatic loading systems with rotationally symmetric loading heads cannot achieve uniform filling of containers with offset dome cover openings or non-circular cross sections, leading to inefficient filling patterns, especially in rail-guided freight wagons with rectangular container sections.
Innovation Solution
A loading head with a distribution head that can be adjusted longitudinally, transversely, and vertically, allowing for acentric filling by shifting and tilting, and featuring a conical deflection surface to ensure uniform distribution across the container, even with non-circular container shapes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a rotationally symmetric loading head is used, then the structure is simple and easy to manufacture, but uniform filling of containers with offset dome cover openings or non-circular cross sections is not possible
Solution Approach 1:
The distribution head is made movable relative to the fixed outlet connector, allowing it to be shifted and tilted to different positions and orientations. This dynamic adjustment capability enables the loading head to adapt to various container shapes and offset dome cover openings while maintaining uniform filling, resolving the contradiction between structural simplicity and adaptability.
Solution Approach 2:
The invention introduces asymmetry through the movable distribution head that can be positioned at different locations and orientations. This allows the system to handle asymmetric container configurations (such as rectangular containers or containers with offset openings) effectively, overcoming the limitation of rotationally symmetric designs.
2Device complexity
If a rotationally symmetric loading head is used, then the device complexity is low, but uniform filling of rectangular container sections is not achieved
Solution Approach 1:
The distribution head's movability adds dynamic adjustment capability without significantly increasing overall device complexity. By allowing the distribution head to be shifted and tilted, the system achieves precise control over material distribution, enabling uniform filling of rectangular containers while keeping the basic structure relatively simple.
Solution Approach 2:
The invention applies local quality by allowing the distribution head to be positioned and oriented specifically to match the local requirements of different container regions. This enables targeted adjustment of material flow patterns to achieve uniform filling in rectangular containers, addressing the specific filling uniformity requirement without redesigning the entire system.
3Adaptability or versatility
If the distribution head is made adjustable and movable, then uniform filling of various container shapes is achieved, but the device complexity increases
Solution Approach 1:
The loading head is segmented into two functional parts: a fixed outlet connector and a movable distribution head. This segmentation allows the complex adjustment functionality to be isolated in the distribution head component, while the rest of the system remains simple. The distribution head can be shifted and tilted independently to adapt to various container shapes without complicating the overall device architecture.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables uniform filling of containers with offset dome cover openings and non-circular cross sections, optimizing the filling process by adjusting the distribution head's position and orientation to match the container's shape, thereby maximizing filling efficiency and preventing material accumulation.
Implementation Method 1
which carries out the lateral distribution of the bulk material in the filling container due to its approximately conical deflection surface
Implementation Method 2
the outlet channel narrows conically in the direction to the outlet end, so as to accelerate the bulk material stream in the direction to the inner space of the filling container
