Built-up Container Concealed Fastening Structure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional built-up containers have exposed bolts that are prone to rust from water, pose a hazard to people and objects, and compromise the integrity and appearance of the container, while also being difficult to assemble.
Innovation Solution
The container design features all fastening parts, including bolts, to be concealed inside, with a reinforced structure that includes a base with threaded holes, side plates with through and threaded holes, and an upper cover, allowing for secure internal engagement without external exposure, enhancing assembly speed and smoothness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If bolts are exposed outside the container for easy assembly, then assembly speed is improved, but the appearance smoothness and integrity are compromised and bolts are prone to rust
Solution Approach 1:
The bolt is nested within a recessed cavity formed in the side plate. The bolt head sits inside the recess and is covered by a cover plate that matches the external surface, creating a nested structure where the fastening component is hidden within the container wall rather than protruding outward.
Solution Approach 2:
The harmful exposed portion of the bolt is extracted and removed from the external surface. Instead of having the bolt extend outward, the design extracts the protruding part and replaces it with a flush-mounted cover plate that maintains the smooth external surface while the bolt remains functional inside.
2Ease of operation
If bolts are exposed outside the container, then assembly is simpler, but safety hazards and rust damage increase
Solution Approach 1:
The bolt is nested within a recessed cavity formed in the side plate. The bolt head sits inside the recess and is covered by a cover plate that matches the external surface, creating a nested structure where the fastening component is hidden within the container wall rather than protruding outward.
Solution Approach 2:
The bolt is placed in a protected environment inside the container wall recess, isolated from the external atmosphere that causes rust. The cover plate creates a barrier that protects the bolt from moisture and air exposure, effectively creating a protective environment similar to an inert atmosphere.

AI summary
A built-up container includes a base, a front and rear side plates, a right and left side plates and a lifted upper cover. The base provides threaded holes and the side plates provide through holes and threaded holes so that the container can be built up with bolts engaging with the threaded holes. It is characterized in that no holes and no bolts expose outside the container with reinforced strength such that integrity and smoothness of the container can be obtained and the fasteners inside the container are free from water and unable to hurt foreign objects. In addition, the container is capable of being set up fast easily to enhance facility of assembling job.
