Refrigeration appliance with an extractable vegetable storage container
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing refrigeration appliances with extractable containers require numerous connection elements for mechanical stability, leading to increased manufacturing costs and inefficiencies, especially in mass-produced models with multiple containers.
Innovation Solution
The refrigeration appliance employs railing devices with grappling members and fixation rods that establish snap-fit connections with receiving devices embedded in the lateral walls, eliminating the need for additional connection elements by using perpendicular engagement surfaces and a rib-like structure to maintain mechanical stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If numerous connection elements are used to secure railing devices, then mechanical stability is improved, but manufacturing cost and complexity increase
Solution Approach 1:
The patent integrates multiple connection functions into a single integrated railing device structure. The railing device combines the rail body, connection elements, and securing mechanisms into one unified component that attaches to the lateral wall, eliminating the need for numerous separate connection elements while maintaining mechanical stability.
Solution Approach 2:
The railing device is designed as a multi-functional component that simultaneously provides guiding, supporting, and securing functions. The single integrated structure performs multiple roles that would traditionally require separate connection elements, thereby reducing overall device complexity while ensuring stable attachment to the lateral wall.
2Stability of the object's composition
If numerous connection elements are used to secure railing devices, then mechanical stability is improved, but manufacturing time and cost increase
Solution Approach 1:
By merging multiple connection elements into a single integrated railing device, the manufacturing process is simplified. Fewer components mean fewer assembly steps, reduced manufacturing time, and lower production costs, while the integrated design maintains the necessary mechanical stability for supporting extractable containers.
Solution Approach 2:
The patent extracts and eliminates unnecessary connection elements from the traditional multi-component design. By removing redundant parts and retaining only the essential securing functions within an integrated structure, the manufacturing process becomes more efficient without compromising mechanical stability.
3Productivity
If a single integrated railing device is used, then manufacturing efficiency is improved, but mechanical stability may be compromised
Solution Approach 1:
The railing device incorporates optimized geometric shapes and structural contours that enhance its load-bearing capacity and attachment strength. The curved and reinforced design features of the integrated structure distribute mechanical stresses effectively, ensuring stability while maintaining the simplified single-component design for efficient manufacturing.
Solution Approach 2:
The railing device may utilize composite material construction or multi-layer structural design that combines different material properties within the single integrated component. This allows the device to achieve high mechanical stability and load-bearing capacity while remaining manufacturable as a single piece, resolving the contradiction between simplicity and strength.
