Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing refrigeration devices require additional elements for sealing the machine room during assembly, complicating the process and increasing the risk of errors or leaks.
Innovation Solution
A method where the side wall element of the refrigeration device is displaced in two distinct directions to engage a sealing element with the housing, creating a foam-tight seal without the need for additional elements, using a spigot and rabbet mechanism for stabilization and a latching hook for secure positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If additional sealing elements are manually installed during assembly, then sealing reliability is improved, but assembly complexity and time increase
Solution Approach 1:
The sealing element is integrated directly onto the side wall element through molding, combining the side wall component and sealing element into a single unified part. This eliminates the need for separate manual installation of sealing elements while maintaining reliable sealing through the foam-tight connection to the housing rebate.
Solution Approach 2:
The sealing element is designed to automatically engage with the housing rebate during the assembly process through the two-stage movement mechanism. The side wall element self-seals by engaging the rebate during foam injection, eliminating the need for manual sealing operations and additional sealing elements.
2Productivity
If side wall element is moved in one complex motion, then assembly speed is maintained, but positioning precision and sealing accuracy deteriorate
Solution Approach 1:
The assembly motion is divided into two distinct sequential stages: first moving the side wall element in a first direction to engage the sealing element with the rebate, then moving in a second direction to achieve final positioning. This segmented approach ensures precise sealing engagement while maintaining efficient assembly throughput.
Solution Approach 2:
The sealing element is pre-positioned on the side wall element during manufacturing. During assembly, the first movement direction preliminarily engages the sealing element with the housing rebate, preparing the sealing interface before the final positioning movement completes the connection.
3Reliability
If manual sealing operations are performed, then sealing quality is improved, but assembly time and labor requirements increase
Solution Approach 1:
The sealing element automatically performs the sealing function through its engagement with the housing rebate during the mechanized two-stage assembly process. The foam-tight seal is created automatically as the side wall element is positioned, eliminating manual sealing operations and reducing assembly time while maintaining high sealing quality.
Solution Approach 2:
The sealing element acts as an intermediary component between the side wall element and housing rebate. It mediates the connection by providing a foam-tight sealing interface that automatically engages during assembly, ensuring high sealing quality without requiring manual intervention.
4Ease of operation
If simple assembly mechanism is used, then assembly ease is improved, but sealing reliability and stability deteriorate
Solution Approach 1:
The assembly mechanism uses simple two-directional movement that is easy to implement and operate. The segmentation of motion into two distinct directions ensures that the sealing element properly engages the rebate while maintaining sealing reliability, achieving both ease of operation and reliable sealing.
Solution Approach 2:
The sealing reliability is enhanced by adding a dimensional aspect to the assembly process - the two-stage movement in different directions creates a foam-tight connection through spatial engagement with the rebate. This dimensional approach to assembly ensures reliable sealing while keeping the mechanism simple and easy to operate.
