Refrigeration control unit with three-axis hinge assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current hinge assemblies for refrigeration control units require distinct hinge leaf parts and separate pin components, limiting their functionality and increasing the number of parts, while user interfaces are restricted by limited character displays, complicating programming and requiring manual cross-referencing.
Innovation Solution
A three-axis symmetrical hinge assembly using identical hinge components with protrusions and recesses for snap-fit assembly, and a refrigeration control unit with a touch screen and liquid crystal display capable of scrolling multiple characters to simplify programming and user interaction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If distinct hinge leaf parts and separate pin components are used, then the hinge assembly can be manufactured with conventional methods, but the number of parts increases and assembly complexity increases
Solution Approach 1:
The patent combines multiple separate hinge components (leaf parts and pin components) into a single integrated hinge assembly. The recesses and protrusions are formed as part of the same molded component, eliminating the need for separate pin components and reducing the total number of parts while maintaining the hinge functionality.
Solution Approach 2:
The hinge assembly is designed to perform multiple functions within a single component structure. The same hinge component provides both the leaf structure for attachment and the pin structure for rotation, making the component universal and reducing overall assembly complexity.
2Device complexity
If identical hinge components with protrusions and recesses are used, then the number of parts is reduced and assembly is simplified, but the hinge assembly requires precise geometric matching
Solution Approach 1:
The hinge component incorporates asymmetric features with specific protrusions and corresponding recesses that must match precisely. This asymmetric geometry ensures proper orientation and fit when assembling identical components, reducing the need for multiple different parts while maintaining manufacturing precision through deliberate geometric design.
3Device complexity
If a limited character display is used in the user interface, then the display hardware is simpler and cost-effective, but the programming process becomes more complex and time-consuming
Solution Approach 1:
The user interface employs a dynamic scrolling display that can show multiple characters sequentially. Instead of requiring a static large display, the interface dynamically presents information in a time-based sequence, allowing a simple display hardware to convey complex programming information efficiently.

AI summary
A hinge assembly is provided. The hinge assembly includes a first hinge component and a second hinge component. The first hinge component includes a leaf portion terminating in a first knuckle and a second knuckle. The first knuckle includes a protrusion and the second knuckle includes a recess. The second hinge component is rotatably coupled to the first hinge component and is structurally identical to the first hinge component. The protrusion of the first hinge component is configured to fit within the recess of the second hinge component, and the protrusion of the second hinge component is configured to fit within the recess of the first hinge component.
