Refrigerator with Separately Formed Cooling System and Clamping Seal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing refrigerators for mobile applications, such as recreational vehicles, have manufacturing limitations due to the integrally formed cooling system with the insulated cabinet, limiting the ability for separate manufacturing and assembly of components.
Innovation Solution
A refrigerator design with a separately formed cooling system that is functionally mountable to an insulated cabinet using a clamping arrangement with first and second clamping elements to seal the refrigerated compartment, allowing for separate manufacturing and assembly of the cooling system and cabinet.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the cooling system is integrally formed with the insulated cabinet, then the structural integrity and sealing are improved, but the manufacturing flexibility and assembly flexibility deteriorate
Solution Approach 1:
The refrigerator is divided into separate modules: the insulated cabinet and the cooling system are manufactured independently and then assembled together using a clamping arrangement. This segmentation allows each component to be optimized and manufactured separately while maintaining functional integration when assembled.
Solution Approach 2:
A clamping arrangement acts as an intermediary component between the insulated cabinet and the cooling system. This mediator enables separate manufacturing of the two main components while providing the necessary mechanical connection and sealing interface when assembled.
2Stability of the object's composition
If the cooling system is integrally formed with the insulated cabinet, then the structural stability is improved, but the ease of manufacture deteriorates
Solution Approach 1:
The refrigerator system is segmented into independently manufacturable components (insulated cabinet and cooling system) that are later assembled through a clamping arrangement, enabling specialized manufacturers to produce each component with optimal processes while maintaining overall structural stability.
Solution Approach 2:
The insulated cabinet and cooling system are manufactured separately in advance by different manufacturers, allowing each to be optimized for its specific manufacturing process before final assembly through the clamping arrangement.
3Ease of manufacture
If the cooling system is separately formed and assembled to the insulated cabinet, then the manufacturing flexibility and ease of repair are improved, but the sealing reliability may deteriorate
Solution Approach 1:
The clamping arrangement serves as an intermediary component that provides both mechanical connection and sealing functionality between the separately manufactured insulated cabinet and cooling system, maintaining sealing reliability while enabling manufacturing flexibility.
Solution Approach 2:
The sealing function is extracted as a separate capability provided by the clamping arrangement rather than being integral to either the cabinet or cooling system, allowing the sealing interface to be optimized independently while maintaining reliable sealing between components.

AI summary
A refrigerator has an insulated cabinet, a cooling system formed separately from the insulated cabinet, and a clamping arrangement including first and second clamping elements sealing a refrigerated compartment of the cabinet from the cooling system. The cooling system is functionally attached to the insulated cabinet after manufacture of the insulated cabinet and the cooling system.
