Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing refrigeration devices are not highly efficient, easy to clean, or cost-effective in manufacturing, and the installation methods are complex and expensive.
Innovation Solution
A refrigeration device with a two-dimensional evaporator surface bent towards the inner wall, covering connection points and simplifying assembly by eliminating the need for additional covering components, and a method for installing the device that involves connecting the evaporator to the cooling circuit and bending it to attach to the inner wall, allowing it to cover its own connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If additional components are used to cover evaporator connections, then cleanability is improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The evaporator is designed with an integrated bent section that directly covers the connection ports, merging the evaporator structure with the protective covering function. This eliminates the need for separate covering components while maintaining cleanability, directly resolving the contradiction between ease of operation and device complexity
Solution Approach 2:
The evaporator structure itself serves dual purposes: heat exchange and covering the connection ports. The bent section of the evaporator automatically provides the protective function without requiring additional components, allowing the system to be self-sufficient and reducing overall device complexity
2Reliability
If multiple separate components are used for evaporator installation, then reliability is improved, but ease of manufacture decreases
Solution Approach 1:
The evaporator is designed as an integrated structure with built-in mounting features and connection port coverage, combining multiple functions into a single component. This reduces the number of assembly steps and improves ease of manufacture while maintaining installation reliability through the unified design
Solution Approach 2:
The evaporator is pre-formed with bent sections and integrated mounting features during manufacturing, so that during installation, the component is ready to be directly mounted and positioned without requiring separate assembly of covering parts or mounting features, simplifying the installation process while ensuring reliability
3Ease of operation
If evaporator connections are exposed, then ease of assembly is improved, but cleanability worsens
Solution Approach 1:
The evaporator structure is merged with the protective covering function through the bent section, which simultaneously serves as part of the heat exchange surface and as a cover for the connection ports. This integrated design improves cleanability by covering exposed connections while avoiding additional structural complexity
Solution Approach 2:
The evaporator is bent into a three-dimensional configuration where a portion is folded back to cover the connection ports from a different spatial dimension. This dimensional transformation allows the same evaporator surface to serve dual purposes without adding separate components, improving cleanability without increasing structural complexity

Function Achieved in This Case
The solution enhances the efficiency and cleanability of the refrigeration device, reduces manufacturing costs, and simplifies the assembly process by integrating the evaporator's bent surface to cover its own connections, improving airflow and reducing the need for additional components.
Implementation Method 1
The cooling circuit absorbs the heat in the interior via a heat exchanger that is thermally coupled to it
Implementation Method 2
a partial area of the evaporator surface is bent towards the inner wall and the evaporator is connected to the refrigerated goods container by means of the bent partial area
