Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing containers for transporting and storing hazardous liquids face issues with deformation due to pressure differences and varying filling levels, leading to loose connections and difficulty in precise handling during filling and emptying, and potential electrical discharge hazards.
Innovation Solution
A container design featuring an integrally formed socket with external and internal threads, a clamping disk, and a screw lock mechanism that secures the socket to the container top, along with an anti-rotation lock and electrically conductive components to prevent loosening and ensure electrical charge dissipation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the socket is directly connected to the inner container without additional fixing mechanisms, then the construction is simple, but the socket position becomes unstable due to inner container deformation from pressure differences and variable filling levels
Solution Approach 1:
The clamping disk serves as an intermediary component between the socket and the container top. It is screwed onto the external thread of the socket and clamps the container top at the opening edge, thereby mediating the connection and ensuring stable positioning of the socket relative to the rigid container top even when the inner container deforms
Solution Approach 2:
The connection system is segmented into distinct functional components: the socket integrated with the inner container, the clamping disk as a separate fixing element, and the screw lock as an additional securing component. This segmentation allows each component to perform its specific function independently while contributing to the overall stability
2Reliability
If the socket connection is secured with additional locking mechanisms, then the connection stability improves, but the device complexity increases
Solution Approach 1:
The clamping disk combines multiple functions in a single component: it provides mechanical clamping of the container top, serves as a mounting surface for the socket, and offers threading for both attachment to the socket and integration with the container top structure. The screw lock similarly combines securing and anti-loosening functions
Solution Approach 2:
The clamping disk performs multiple functions simultaneously: it acts as a clamp to secure the container top, provides a threaded mounting interface for the socket, and serves as a structural element that distributes mechanical loads. This multi-functionality reduces the need for separate dedicated components
3Ease of manufacture
If the container top and socket are made of non-conductive plastic, then the material compatibility and purity are maintained, but electrical discharge hazards occur during filling and emptying operations
Solution Approach 1:
The container top is made of electrically conductive plastic in the specific region where electrical discharge protection is needed, while maintaining plastic material properties. This local modification of electrical conductivity addresses the harmful factor without changing the overall material composition or requiring additional non-plastic components
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design provides stable, safe, and precise handling during filling and emptying by preventing unintentional loosening and electrical discharge, enhancing safety and operational efficiency.
Implementation Method 1
A clamping disk with an internal thread can be screwed to the external thread of the socket, thereby clamping the container top at the edge of its opening
Implementation Method 2
The invention comprises a screw lock which interacts with the external thread of the socket and the internal thread of the clamping disk and is suitable for preventing unintentional loosening of the clamping disk and the socket
Implementation Method 3
at least the rigid container top consists of electrically conductive plastic. The conductivity is generated, for example, in such a way that electrically conductive carbon black particles or aluminum particles are admixed to the plastic. The electrical conductivity is adjusted in such a way as to dissipate electrical charges which may be generated as a result of frictional electricity during filling and emptying of the inner container

AI summary
A container for the transport and storage of liquids comprises at least one upwardly open socket at the top of an inner container. A clamping disk has an internal thread that can be screwed onto an external thread of the socket, thereby clamping a container top at the edge of its opening. A screw lock interacts with the external thread of the socket and the internal thread of the clamping disk and prevents unintentional loosening of the clamping disk and the socket.
