Refrigerator Door Insert Strips for Balanced Module Pressing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing refrigerator door designs face challenges in securely and efficiently integrating electrical modules without causing damage, while also optimizing space and reducing the strength and size requirements of components.
Innovation Solution
The design incorporates multiple insert strips with elastic pressing portions that are spaced apart and extend along the insertion direction, allowing for balanced force distribution on the electrical module, which is pressed towards the front panel without direct friction, reducing the size and strength requirements of each pressing portion, and enabling easy insertion and removal through an accessible inlet.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a single pressing structure is used to secure the electrical module, then the structure is simple, but the force distribution is unbalanced and may damage the module
Solution Approach 1:
The pressing structure is divided into multiple insert strips (first, second, third insert strips) spaced apart from each other, with each strip containing multiple pressing portions. This segmentation distributes the pressing force across multiple contact points, achieving balanced force distribution while maintaining a relatively simple overall structure.
Solution Approach 2:
Each insert strip is equipped with multiple pressing portions at different locations, allowing different regions of the electrical module to experience appropriate local pressure. This ensures that the front surface of the electrical module contacts the front panel evenly without concentrated stress points that could cause damage.
2Ease of manufacture
If the electrical module is pressed directly against the front panel during insertion, then the installation is simple, but parts facing the front panel may be damaged due to friction
Solution Approach 1:
The insert is designed to be inserted into the containing chamber first, establishing the pressing force structure before the electrical module is fully installed. This preliminary positioning of the pressing mechanism allows the module to be secured without direct frictional contact during the insertion process, protecting sensitive parts.
3Force
If the insert occupies large space in the door, then the pressing force can be sufficient, but the space for other components is reduced
Solution Approach 1:
The insert is divided into multiple thin insert strips spaced apart, which collectively provide sufficient pressing force through distributed contact while occupying less overall volume compared to a single solid pressing structure. The spaced arrangement reduces material usage and space occupation.
Solution Approach 2:
The pressing force is distributed across multiple dimensions by arranging insert strips and pressing portions in different locations within the containing chamber. This multi-dimensional distribution achieves sufficient total force with smaller individual component sizes, reducing overall space requirements.
