Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing transport containers face challenges in efficiently inserting and removing inliners without causing wrinkles or tears, leading to potential leakage and contamination due to improper fit and complex cleaning processes.
Innovation Solution
An inliner with shaped rods made of flexible material, operatively connected to ensure optimal fit within the transport container, facilitated by an application hose for easy insertion and removal, and a molded part for secure attachment during filling and emptying.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a thin-walled flexible inliner is inserted into a transport container, then the transport container can be used without thorough cleaning, but the inliner may form wrinkles and creases that disrupt flow and cause leakage
Solution Approach 1:
The inliner is pre-formed with shaped rods that define its three-dimensional geometry before insertion. The rods are arranged in a folded state within the inliner, and upon insertion into the transport container, they automatically expand and assume their predetermined shapes, pre-positioning the inliner to fit the container walls without wrinkles or creases.
Solution Approach 2:
The inliner is constructed as a flexible thin-walled structure that can conform to the inner contour of the transport container. The flexible material allows the inliner to adapt to the container's geometry while maintaining seamlessness, preventing wrinkles and creases that would otherwise cause leakage.
2Ease of operation
If the inliner is inserted in a folded state through a filling opening, then insertion is simplified, but the inliner may not assume the correct shape and may retain creases
Solution Approach 1:
The shaped rods are pre-configured within the inliner in a folded state, and upon insertion into the transport container, they automatically expand and assume their predetermined shapes, pre-positioning the inliner to fit the container walls without wrinkles or creases.
Solution Approach 2:
The shaped rods are designed to be deformable, allowing them to be compressed into a folded state for easy insertion through the filling opening. Once inside the container, the rods dynamically expand to their predetermined shapes, transforming the inliner from a compact folded state to its full operational three-dimensional form.
3Reliability
If connection devices are used to attach the inliner to the transport container, then the inliner can be securely fixed, but the attachment process becomes complex and time-consuming
Solution Approach 1:
The shaped rods are designed to automatically assume their predetermined shapes upon insertion into the transport container, self-positioning the inliner without requiring external connection devices or complex attachment mechanisms. The inliner essentially attaches itself to the container walls through the geometric constraint of the rods.

Function Achieved in This Case
Ensures a seamless fit of the inliner within the transport container, preventing wrinkles and tears, allowing easy and contamination-free filling and emptying processes, reducing the need for complex cleaning and waste generation.
Implementation Method 1
shaped rods (14) made of a flexible material, operatively connected to the inliner (10) such that the inliner (10) opens in the transport container (12) with the shaped rods (14) when the inliner (10) is inserted into the transport container (12)

AI summary
The invention relates to a liner (10) which is designed to receive filling material (40) and to be inserted through an opening in a container wall of a transport container (12). The liner (10) is operatively connected to shaping rods (14) which are designed to open together with the liner (10) in the transport container (12) according to the umbrella principle when the liner is inserted into the transport container, in order to position the liner so that it rests form-fittingly and neatly in the interior of the liner. Subsequently, the shaping rods (14) close again when the liner (10) is discharged, in order to remove the emptied and now contaminated liner (10) together with a potential residual amount of liquid through the filling opening in the transport container.
