Refrigerator Partition Wall Receiving Unit for Space-Efficient Storage
Find Innovative SolutionsGenerate Solutions
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 additional storage components and compromise storage efficiency when trying to add new receiving components.
Innovation Solution
A receiving unit is integrated into a partition wall to isolate storage spaces, allowing for additional storage without reducing the existing space, with a door mechanism that provides restoring force and reduces movement speed, and is designed for easy manipulation and foreign substance prevention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the number or volume of drawers and shelves is reduced to install a new receiving component, then the new receiving component can be added, but the storage efficiency decreases because the drawers or shelves cannot accommodate the designed amount of storage objects
Solution Approach 1:
The receiving component is installed on the partition wall surface (a two-dimensional surface) rather than occupying three-dimensional storage space that would displace drawers or shelves. This allows the new component to be added without reducing the volume available for traditional storage components, thereby maintaining storage efficiency while increasing adaptability.
2Adaptability or versatility
If the distance between shelves or between shelf and drawer is reduced to add receiving component space, then the new receiving component can be installed, but the storage capacity of existing components is reduced
Solution Approach 1:
The partition wall is segmented to include a dedicated installation space for the receiving component. This segmentation allows the receiving component to be added without affecting the volume or spacing of shelves and drawers, as it occupies a separate, dedicated portion of the partition wall structure.
3Adaptability or versatility
If a new receiving component is added to the storage space, then the functionality is enhanced, but the storage space volume is reduced due to installation requirements
Solution Approach 1:
The receiving component utilizes the partition wall surface area (2D dimension) for installation rather than consuming 3D storage volume. This dimensional transition allows functionality enhancement without sacrificing storage space volume, as the component is mounted on the wall surface rather than occupying interior space.
4Ease of operation
If the door movement speed is reduced from a specific point during opening and closing, then the door control is improved, but the manipulation time increases
Solution Approach 1:
The door experiences periodic variation in movement speed during its opening and closing cycle. The speed is reduced only during the critical period when the door passes over the specific point (improving control), while maintaining higher speed during other portions of the movement (minimizing total manipulation time). This periodic speed adjustment optimizes both control and efficiency.
