Solution Overview
Problem
Existing household refrigeration appliances require significant installation effort due to the complexity of mounting components in the machine room, which can lead to increased time and potential instability of the components.
Innovation Solution
A household refrigeration appliance design featuring a carrier shell with snap-in and plug-in connections that allow components to be securely fastened without additional fasteners, utilizing a combination of snap-in and plug-in connections for stable mechanical mounting, and incorporating C-shaped grooves for enhanced stability and accessibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional mounting methods with multiple separate fasteners are used, then components can be securely fixed, but the installation effort and time increase significantly
Solution Approach 1:
The patent combines multiple separate fastening functions into a single integrated carrier shell that incorporates both snap-in connections and plug-in connections. This merging eliminates the need for multiple separate fasteners, reducing installation complexity while maintaining secure component fixation.
Solution Approach 2:
The carrier shell serves multiple functions simultaneously: it provides structural support, enables snap-in connections for quick attachment, offers plug-in connections for additional securing, and ensures proper component positioning. This multi-functionality reduces the overall number of components needed while maintaining installation security.
2Productivity
If simple mounting structures are used, then assembly is faster, but mechanical stability and security of component mounting decrease
Solution Approach 1:
The carrier shell incorporates dynamic connection mechanisms that allow for quick assembly through snap-in actions while providing stable fixation once mounted. The design enables rapid component attachment without compromising long-term mounting reliability.
Solution Approach 2:
The carrier shell integrates different connection types (snap-in and plug-in) within a single structural component, creating a composite fastening system that combines the speed of snap connections with the stability of plug connections, thereby achieving both fast assembly and reliable mounting.
3Reliability
If multiple separate fastening elements are used, then secure mounting is achieved, but the number of components and assembly complexity increase
Solution Approach 1:
The patent merges multiple fastening functions into a single integrated carrier shell structure that provides both snap-in and plug-in connections, eliminating the need for separate fasteners and reducing the total component count while maintaining mounting security.
Solution Approach 2:
The carrier shell is designed with segmented connection points that provide independent snap-in and plug-in connection zones, allowing secure mounting of components through multiple discrete connection points within a single integrated structure, thereby reducing overall component complexity.
