Hidden Hinge Fixing Structure for Concealed Container Doors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing container designs with hidden hinges are compromised by visible hinge mounting holes and positioning structures, affecting the appearance and strength of the container.
Innovation Solution
A container with a hidden hinge fixing structure that uses grooves with position limiting structures and elastic or protruding elements to secure the hinge bases within the container's sidewalls, making the hinge completely invisible and enhancing the strength of the hinge mounting portions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If hinge mounting holes and positioning structures are provided on the side plate and door, then the hinge can be securely installed, but the appearance of the container is compromised and the strength of the mounting parts is reduced
Solution Approach 1:
The invention extracts the hinge mounting function from the visible outer surface of the container by providing grooves within the thickness of the side plate and door. The hinge bases are received within these grooves, which are positioned inside the container structure rather than on the external surface, thereby removing the visual impact of mounting features from the appearance while maintaining secure hinge installation through the groove structure with position limiting structures.
2Ease of manufacture
If hinge mounting holes are provided on the side plate and door, then the hinge can be installed, but the strength of the hinge mounting parts is affected
Solution Approach 1:
The invention embeds the hinge bases within grooves that are formed within the thickness of the side plate and door structures. The grooves with position limiting structures create a nested configuration where the hinge bases are received inside the container walls rather than being mounted on the surface. This nesting approach maintains the structural integrity and strength of the mounting parts while still enabling secure hinge installation through the internal groove structure.
3Ease of operation
If a traditional hinge structure is used, then the hinge can be easily installed, but the hinge is visible from the appearance of the container
Solution Approach 1:
The invention transitions the hinge mounting from a two-dimensional surface mounting approach to a three-dimensional internal groove structure. By providing grooves within the thickness of the side plate and door, and receiving the hinge bases within these grooves, the hinge mounting is moved into the third dimension (internal structure) rather than remaining on the external surface. This dimensional change makes the hinge completely invisible from the appearance while maintaining ease of installation through the structured groove design with position limiting features.

AI summary
A hinge fixing structure used to hold a hidden hinge on a container, and a hidden hinge and a container. The hidden hinge comprises an upper hinge base, a hinge body and a lower hinge base. The container comprises a side plate and a door, which are respectively provided with grooves formed by the internal and external sidewalls thereof and used to accommodate hinge bases. The hinge fixing structure comprises position limiting structures located in grooves and used to prevent the hinge bases from releasing from the mouth portions of grooves and positioning structures provided on the upper hinge base and the lower hinge base and engaged with the limiting structures respectively. The position limiting structures are engaged with the positioning structures respectively so that the hidden hinge is held on the container, and the hidden hinge is completely invisible from the appearance of container when the door is closed. In the present invention, for the container employing the hinge fixing structure and the hidden hinge of the present invention, the hinge is completely invisible from the appearance of the container after installation, and the disassembly of the hinge becomes more convenient.
