Solution Overview
Problem
Existing refrigerating appliances face challenges in maximizing usable space within the storage compartment while ensuring uniform air distribution and maintaining insulation properties.
Innovation Solution
The refrigerating appliance features a rear wall with a central recess and lateral recesses in the insulating plate, forming a central air guiding channel, which enhances uniform air distribution and prevents condensation, while the fixation structures with bulges and pockets allow for efficient attachment and minimal protrusion, maximizing space and insulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the rear wall includes a central recess extending in vertical direction, then the cross-sectional area of the central air guiding channel is increased, but the usable space in the storage compartment may be reduced
Solution Approach 1:
The recesses in the insulating plate extend beyond the central recess of the rear wall in the transverse direction, creating a three-dimensional air distribution network that maximizes the use of available space while maintaining effective air guiding channel cross-sectional area
Solution Approach 2:
The air distribution system is segmented into a central air guiding channel formed by the rear wall recess and multiple lateral air distribution channels formed by the insulating plate recesses, allowing independent optimization of each component's geometry
2Stability of the object's composition
If lateral recesses extend beyond the central recess in transverse direction, then air distribution uniformity is improved, but the device complexity increases
Solution Approach 1:
The insulating plate integrates multiple functions: thermal insulation, structural support for the air distribution assembly, and formation of lateral air distribution channels through recesses, thereby reducing the need for separate components and simplifying the overall device
Solution Approach 2:
The insulating plate features localized recesses positioned strategically to extend beyond the central recess in the transverse direction, creating optimal air distribution patterns without requiring complex modifications throughout the entire structure
3Ease of manufacture
If fixation structures with bulges and pockets are used, then attachment efficiency is improved, but the protrusion into the storage compartment increases
Solution Approach 1:
The fixation structures utilize nested geometry where bulges and pockets are positioned to interlock efficiently, allowing secure attachment of the insulating plate to the rear wall while minimizing the overall protrusion into the storage compartment
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design achieves more uniform air distribution, prevents condensation, and maximizes usable space without compromising insulation, thus improving energy efficiency and visual appearance.
Implementation Method 1
The central recess of the insulating plate is arranged corresponding to the central recess of the rear wall, so that the central recess of the rear wall and the central recess of the insulating plate, together, define a central air guiding channel
Implementation Method 2
multiple lateral recesses to distribute air flowing in the central recess are formed in the first surface of the insulating plate. The lateral recesses branch off from the central recess and extend along a transverse direction
Implementation Method 3
an insulating plate having a first surface facing an inner surface of the rear wall and an opposite second surface facing the storage compartment
Implementation Method 4
The refrigerating appliance further includes a plurality of fixation structures, each fixation structure comprising a pocket formed in the inner surface of the rear wall and a bulge formed in the inner surface of the rear wall
