Protective Container with Ribs and Projection for Hazardous Substance Transport
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing protective containers for hazardous substances are complex, expensive to manufacture, and inadequate in providing comprehensive mechanical protection during transport and handling.
Innovation Solution
A protective container composed of two parts: a cup-shaped lower part and a lid, featuring ribs for axial and lateral stabilization, an inward projection for secure fitting, and a retaining ring for additional security and sealing, allowing for easy assembly and cost-effective production.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple complex components are used to secure the inner container, then the protection reliability is improved, but the device complexity and manufacturing cost increase
Solution Approach 1:
The patent combines multiple securing functions into a single integrated lid structure. The lid incorporates both the inward projection for axial positioning and the lateral wings for radial securing, eliminating the need for separate components. This merging of functions reduces device complexity while maintaining comprehensive protection of the inner container against both axial and radial movements.
Solution Approach 2:
The lid serves multiple functions simultaneously: it closes the container opening, secures the inner container axially through the inward projection, prevents lateral movement through the wings, and provides structural support. This multi-functionality reduces the total number of components needed while achieving reliable protection.
2Reliability
If multiple complex components are used to secure the inner container, then the protection reliability is improved, but the manufacturing cost increases
Solution Approach 1:
By combining multiple securing features into a single lid component, the patent reduces the number of parts that need to be manufactured, stored, and assembled. This integration simplifies the supply chain and reduces manufacturing costs while maintaining comprehensive protection functionality.
Solution Approach 2:
The lid is designed as a single molded piece with integrated features (inward projection, lateral wings, sealing surface) rather than multiple separate components. This segmentation into one optimized component simplifies manufacturing processes and reduces assembly steps, thereby lowering production costs.
3Ease of manufacture
If a simple structure is used for the protective container, then the ease of manufacture is improved, but the protection capability may be insufficient
Solution Approach 1:
The protective container is divided into two simple components (container and lid) that can be easily manufactured, but each component contains strategically designed geometric features (inward projection, lateral wings, engagement surfaces) that provide robust mechanical protection and secure positioning of the inner container.
4Stability of the object's composition
If multiple securing mechanisms are implemented, then the stability of the inner container is improved, but the ease of operation decreases
Solution Approach 1:
Multiple securing mechanisms (axial positioning, lateral restraint, sealing) are merged into a single lid component that is installed in one straightforward operation. This eliminates the need for multiple separate installation steps while maintaining comprehensive stability of the inner container.

AI summary
The case has a cover (5) connected with a cup-shaped lower part (3), and ribs (13) provided in the lower part for fixing a container (25) to be accommodated at a distance from a wall (9) and a base (7) of the lower part. A projection (19) is provided in the cover for setting the container in a direction of an axis of the case. The cover is fixable at the lower part by screwing, locking connection or bayonet locking-type connection, and the ribs radially project into interior of the lower part. The projection is integrally formed with the cover.
