Adjustable Refrigerator Door Basket for Variable-Height Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional refrigerators lack efficient space utilization and flexibility in storing items of varying heights within their compartments, as the fixed shelves and compartments do not easily accommodate tall or short items without compromising the cold air retention and aesthetic design.
Innovation Solution
A refrigerator design featuring a moving basket system within the storage assembly, where the basket is vertically movable along a rail and adjustable in height using an operation mechanism, allowing for partitioning of the storage case into upper and lower spaces, and an inner door with a sub-basket that can be moved vertically to overlap with a main-basket, enhancing space efficiency and accessibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If fixed shelves and compartments are used in conventional refrigerators, then the structural simplicity and manufacturing ease are maintained, but the space utilization efficiency and flexibility for storing items of varying heights deteriorate
Solution Approach 1:
The patent applies the dynamics principle by transforming fixed shelves into movable baskets that can be adjusted vertically along guide rails. The baskets are equipped with operation mechanisms allowing users to move them up and down, enabling dynamic adaptation to different storage needs and item heights while maintaining a relatively simple overall structure
Solution Approach 2:
The storage space is segmented into multiple movable baskets that can be independently adjusted. Each basket acts as a separate storage unit that can be positioned at different heights, providing flexibility for storing items of varying heights without requiring a completely complex reconfiguration of the entire storage system
2Adaptability or versatility
If the storage space is divided into fixed compartments, then the structural stability and cold air retention are maintained, but the space efficiency and accessibility for items of different heights deteriorate
Solution Approach 1:
The movable baskets allow users to dynamically adjust storage configurations by moving baskets up and down along guide rails. This dynamic adjustment improves accessibility to items at different heights and optimizes space efficiency without compromising the structural stability of the storage assembly
Solution Approach 2:
The patent introduces vertical movement capability to the storage baskets, adding a dimensional aspect to storage flexibility. Users can adjust baskets along the vertical dimension to access items more easily and optimize space utilization for items of different heights
3Adaptability or versatility
If adjustable storage configurations are implemented, then the flexibility and space utilization are improved, but the potential impact on cold air retention and aesthetic design increases
Solution Approach 1:
The movable baskets are designed to maintain proper spacing and positioning when adjusted, ensuring that cold air circulation pathways are preserved. The guide rails and operation mechanisms are configured to allow movement without creating gaps or openings that would compromise cold air retention
