Solution Overview
Problem
Existing cooling devices face challenges in achieving a safe and rigid assembly of their housing, which can lead to instability and potential damage during use.
Innovation Solution
The solution involves a household appliance with a housing connection arrangement that includes an outer liner, an inner liner, a housing frame, an elastic member, and a reinforcement member. The elastic member and reinforcement member work together to provide increased rigidity and prevent dropping, while also allowing for easy and safe assembly through the use of connection lugs and channels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a housing frame connects the outer liner to the inner liner without additional reinforcement, then the structure is simpler, but the rigidity and stability of the housing are insufficient
Solution Approach 1:
The patent employs a composite connection arrangement combining an elastic member (flexible element) with a reinforcement member (rigid element featuring connection lugs). This composite structure integrates the flexibility needed for assembly with the rigidity required for structural stability, resolving the contradiction between simplicity and strength by using materially diverse components working together.
Solution Approach 2:
The housing connection is segmented into distinct functional components: the elastic member providing flexibility and the reinforcement member providing structural rigidity. This segmentation allows each component to specialize in its optimal function, with the reinforcement member's connection lugs specifically addressing the rigidity requirement without requiring complete redesign of the entire housing structure.
2Ease of operation
If the housing uses rigid connection elements only, then the assembly is stable, but the assembly process becomes difficult and may cause damage
Solution Approach 1:
The elastic member introduces dynamic flexibility to the otherwise rigid connection system. During assembly, this flexibility allows components to be positioned and connected more easily, reducing assembly difficulty. Once assembled, the elastic member maintains reliable connection through its elastic properties, ensuring assembly stability without requiring excessive rigidity in the connection elements themselves.
Solution Approach 2:
The elastic member acts as an intermediary between the rigid housing frame components, mediating the connection between the outer liner and inner liner. This intermediary element facilitates easier assembly by providing flexibility during the connection process while maintaining reliable stability once assembled, effectively bridging the gap between ease of operation and assembly reliability.
