Solution Overview
Problem
Conventional refrigerators face challenges in efficiently utilizing storage space due to limitations in the number and volume of shelves and drawers, which restrict the addition of new receiving components without compromising storage capacity, leading to decreased storage efficiency.
Innovation Solution
A receiving unit is integrated into the refrigerator, featuring a depressed partition wall with an introduction port, allowing for additional storage space without reducing existing compartment volumes, and a receiver door that opens and closes horizontally to facilitate easy access and cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the number or volume of drawers and shelves is increased to improve storage capacity, then storage efficiency is improved, but the volume of the storage space available for other receiving components is reduced
Solution Approach 1:
The receiver is integrated into the partition wall structure, utilizing the vertical dimension and wall thickness space that would otherwise be unused. This allows adding receiving functionality without occupying horizontal storage space that would compete with drawers and shelves.
Solution Approach 2:
The receiver is nested within the partition wall structure, with the partition wall serving as both a structural divider and a container for the receiver. This nested configuration allows the receiver to occupy space that would otherwise be structural overhead.
2Adaptability or versatility
If a new receiving component is added to the storage space, then storage versatility is improved, but the volume of existing drawers and shelves is reduced
Solution Approach 1:
The new receiving component (receiver) is placed in the vertical dimension within the partition wall, rather than competing for horizontal storage volume. This dimensional separation allows adding versatility without reducing existing drawer and shelf volumes.
Solution Approach 2:
The receiver is localized to a specific region within the partition wall, creating a specialized receiving zone that does not interfere with the general storage function of drawers and shelves. This local integration maintains overall storage capacity while adding specific functionality.
3Quantity of substance
If the distance between shelves and drawers is reduced to maximize storage space utilization, then storage density is improved, but accessibility and ease of operation deteriorate
Solution Approach 1:
The receiver provides an additional access point at a different vertical level, allowing users to access stored items without reaching across or removing other components. This vertical distribution of access points maintains accessibility while increasing overall storage density.
