Refrigerator Box Body Hinge Mounting to Reduce Packing Volume
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The convex hinges of traditional refrigerator box bodies increase transportation costs due to the need for larger packing boxes, resulting in gaps that reduce loading capacity.
Innovation Solution
A refrigerator box body design featuring mounting bases with depressions and guide grooves that allow hinges to be mounted internally, reducing the external space occupied by hinges and enhancing mounting convenience and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If hinges are mounted externally on the box body, then the hinges are easy to install and maintain, but the hinges protrude from the box body increasing the packing box size and reducing loading capacity
Solution Approach 1:
The hinge mounting base is nested within a depression formed in the box body, with the mounting base protruding inward from the outer surface. This nesting arrangement allows the hinge assembly to be contained within the box body structure rather than protruding externally, reducing the overall volume required for packaging while maintaining hinge functionality and accessibility for installation and maintenance.
Solution Approach 2:
The hinge mounting structure transitions from a two-dimensional external surface mounting to a three-dimensional internal depression mounting. By utilizing the depth dimension of the box body through formed depressions, the hinge assemblies are positioned within the box body volume rather than extending outward, effectively reducing the external footprint and packing box requirements.
2Ease of manufacture
If hinges are mounted externally on the box body, then the hinge structure is simple and easy to manufacture, but there are gaps between the refrigerator box body and packing box reducing loading quantity
Solution Approach 1:
The hinge mounting base is nested within a depression formed in the box body, with the mounting base protruding inward from the outer surface. This nesting arrangement allows the hinge assembly to be contained within the box body structure rather than protruding externally, reducing the overall volume required for packaging while maintaining hinge functionality and accessibility for installation and maintenance.
Solution Approach 2:
The depressions are pre-formed in the box body during the molding process, and the hinge mounting bases are designed to fit into these pre-formed cavities. This preliminary preparation of the mounting locations allows for efficient assembly and ensures that the hinge assemblies are properly positioned within the box body volume, maximizing space utilization and loading capacity.
3Device complexity
If hinges are mounted externally on the box body, then the hinge design is traditional and simple, but the protrusion increases freight cost due to reduced loading capacity
Solution Approach 1:
The hinge mounting base is nested within a depression formed in the box body, with the mounting base protruding inward from the outer surface. This nesting arrangement allows the hinge assembly to be contained within the box body structure rather than protruding externally, reducing the overall volume required for packaging while maintaining hinge functionality and accessibility for installation and maintenance.
