Heat-insulated housing of a household refrigeration appliance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The base plate in household refrigeration appliances is prone to shifting or detaching from the side plate support during assembly, requiring additional tools for fixation, which complicates manufacturing and hinders automation.
Innovation Solution
A heat-insulated housing design featuring a base plate with side edges inserted into insertion grooves on the side plate support, equipped with a stop structure and clamping structure that restricts movement, allowing assembly without additional components or tools, facilitated by elastic deformation of the groove side walls and clamping structures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the base plate is supported by the side plate support using a simple insertion structure, then the assembly process is simple, but the base plate shifts or detaches during assembly
Solution Approach 1:
The clamping structure utilizes elastic deformation to create a dynamic locking mechanism. The groove side wall and clamping structure deform elastically during insertion, then return to their original shape to clamp the base plate securely, preventing detachment while maintaining assembly simplicity
Solution Approach 2:
The patent changes the physical state of the groove side wall from rigid to elastic by selecting appropriate materials and designing the wall thickness. This allows the side wall to deform under insertion force and then maintain a clamping force, transforming the connection from a simple slide-fit to a secure elastic lock
2Reliability
If an additional auxiliary tool is used to fix the base plate and side plate support during assembly, then the connection stability is improved, but the manufacturing process becomes complex and automation is hindered
Solution Approach 1:
The clamping structure is designed to automatically lock the base plate in position through its own elastic deformation mechanism. The groove side wall deforms during insertion and then naturally clamps the base plate without requiring any external tools or additional components, enabling automated assembly while ensuring connection stability
Solution Approach 2:
The patent removes the need for external auxiliary fixing tools by integrating the clamping function directly into the side plate support structure. The groove side wall itself becomes the clamping element, eliminating the need for separate fastening devices or tools
3Productivity
If the base plate can move freely during insertion, then the assembly process is fast, but heat insulation material leaks during foaming
Solution Approach 1:
The clamping structure is designed to automatically engage and lock the base plate in the correct position during the insertion process itself. The elastic deformation occurs during insertion, preliminarily securing the base plate before heat insulation material is applied, preventing leakage while maintaining assembly speed

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Ensures stable assembly and simplifies manufacturing, enabling automated production by maintaining the base plate and side plate support connection without additional components, while preventing heat insulation material leakage.
Implementation Method 1
the stop structure is adapted to contact the clamping structure and restrict movement of the side edge section relative to the insertion groove in a direction opposite to an insertion direction of the side edge section into the insertion groove
