Wire Basket Rail Coupling for Airflow-Stable Refrigerator Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In domestic refrigeration appliances, closed containers hinder air circulation and can lead to moisture accumulation, negatively impacting food shelf life and storage conditions.
Innovation Solution
A wire basket assembly with a pull-out rail apparatus featuring a coupling unit that securely attaches to the wire basket by engaging with wires at different orientations, providing stable and easy handling without additional fastening elements, ensuring adequate air circulation and reduced moisture issues.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If closed containers with continuous walls are used, then structural strength and containment are improved, but air circulation is hindered and moisture accumulates
Solution Approach 1:
The container walls are constructed with a porous structure featuring through-going openings that allow air circulation while maintaining structural integrity. This porous design enables moisture evaporation and prevents condensation accumulation, directly resolving the contradiction between structural strength and moisture control.
2Object-affected harmful factors
If wire baskets are used, then air circulation is improved, but fastening stability becomes difficult to achieve
Solution Approach 1:
The coupling unit integrates multiple fastening functions into a single component that simultaneously engages with multiple wires of the basket in different spatial orientations. This merging of fastening elements provides stable attachment while preserving the wire basket's air circulation properties.
Solution Approach 2:
The coupling unit fastens to wires oriented in different spatial dimensions (multiple orientations), creating a multi-dimensional fastening system. This approach achieves stable attachment on the wire basket structure without compromising air circulation through the basket walls.
3Reliability
If multiple additional fastening elements are added to secure the pull-out rail apparatus, then fastening stability is improved, but device complexity increases
Solution Approach 1:
Multiple fastening functions are merged into a single coupling unit component. This unified fastening element engages with multiple wires simultaneously, providing stable attachment without requiring separate fastening elements, thereby reducing device complexity while maintaining reliability.
Solution Approach 2:
The coupling unit serves multiple functions simultaneously: it attaches the pull-out rail apparatus to the wire basket, provides fastening stability, and maintains compatibility with the wire basket structure. This multi-functionality eliminates the need for additional specialized fastening components.
