Container Cover Corner Locking Protrusion Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing container cover designs are inconvenient to operate and lack sufficient structural strength, especially when stacking containers, due to the placement of locking structures away from the top corners, which compromises stability and ease of use.
Innovation Solution
The container cover features position limiting protrusions at its corners with integrated locking mechanisms, including a driving member and locking member, allowing for secure locking and easy operation without occupying valuable space, and includes a tongue and latch system for secure engagement with the side plates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual operated cover locks with latches are used for connecting the cover to the container body, then the cover can resist the shocking of the internal liquid, but the manual operated lock is not convenient for operation
Solution Approach 1:
The locking structure uses elastic restoration to automatically lock the cover without manual operation. The elastic component self-activates to engage the locking mechanism, eliminating the need for manual locking operations while maintaining secure connection between cover and container body
Solution Approach 2:
The locking structure transitions from static manual locking to dynamic elastic restoration. The elastic component provides automatic locking through its inherent elastic properties, allowing the system to adapt and lock itself without external manual intervention
2Adaptability or versatility
If the locking structure is placed away from the top corners of the container body, then there is space for stacking containers, but the locking effect becomes less stable due to larger deformation at those portions
Solution Approach 1:
The position limiting protrusion extends vertically from the cover surface, creating a three-dimensional locking structure. This vertical dimension allows the locking mechanism to engage with the container body at optimal structural points while maintaining stacking capability, as the protrusion height can be adjusted to clear stacking surfaces
3Reliability
If the locking structure is placed close to the top corners of the container body, then the locking effect is more stable due to smaller deformation, but the portions adjacent to top corners become the main bearing portions affecting stacking height
Solution Approach 1:
The locking structure is segmented into the position limiting protrusion and the locking mechanism within it. This segmentation allows the protrusion to provide stable corner-based locking while the internal locking mechanism engages at optimized points that do not interfere with stacking surfaces, separating the locking function from the bearing function
4Ease of manufacture
If depressing space is provided on the cover to place the locking structure, then the locking mechanism can be accommodated, but the depressing space affects the stacking height of the container body
Solution Approach 1:
The locking mechanism is nested within the position limiting protrusion itself. The protrusion serves as both the structural element providing positioning and the housing for the locking mechanism, eliminating the need for separate depressing space and preventing interference with stacking height

AI summary
Disclosed is a container cover (1) for use in cooperation with a container (100), wherein the container (100) comprises a bottom (4) and side plates (2), the container cover (1) has four corners (10), each of which is provided with a position limiting protrusion (11), and the position limiting protrusion (11) protrudes from an upper surface of the container cover (1) integrally; and at least one position limiting protrusion (11) is provided with a locking means (3), which is used to lock the container cover (1) and the container (100). The structure provides the locking means of the cover and a container body on a stacking limiting structure without occupying container space therebelow, and meanwhile, simple operation and good structural strength are achieved.
