Refrigerating appliance comprising a door tray
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current refrigeration appliance door racks lack sufficient flexibility to accommodate the increasing variety of refrigerated goods, particularly bottles and tetra packs of varying sizes, as their height adjustment options are not adequately versatile.
Innovation Solution
A door rack system comprising a floor and a bracket, both designed as independent modules with a height adjustment device integrated into the refrigeration appliance door, allowing the bracket to be variably positioned relative to the floor, enabling adaptation to a wide range of goods heights using standard components, ensuring stability and flexibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If door racks are designed with fixed height brackets for different goods types, then specific goods can be securely held, but the door rack lacks flexibility to accommodate varying sizes and shapes of refrigerated goods
Solution Approach 1:
The bracket is designed to be height-adjustable along the door rack structure, allowing it to be positioned at different heights to accommodate various goods sizes. This dynamic adjustment capability enables the same door rack to adapt to different storage needs without requiring multiple fixed configurations.
Solution Approach 2:
A single door rack design with adjustable brackets can serve multiple functions by accommodating different goods types (bottles, tetra packs, containers) of varying heights. The universal design eliminates the need for separate door racks for different goods categories.
2Adaptability or versatility
If multiple fixed door rack variants are produced for different goods types, then specific storage needs are met, but production costs increase due to multiple component variants
Solution Approach 1:
The door rack employs a universal bracket design that can be adjusted to different heights and positions, allowing a single standard component to replace multiple variant-specific components. This standardization reduces the number of unique parts that need to be manufactured and inventoried.
Solution Approach 2:
Instead of producing different door rack variants with fixed parameters, the invention allows dynamic change of the bracket height parameter. This single parameter adjustment enables the same physical structure to adapt to different storage requirements, eliminating the need for multiple manufacturing processes.
3Reliability
If door racks have high edges to secure tall bottles, then tall bottles are secured, but shorter goods like eggs or butter cannot be optimally stored
Solution Approach 1:
The bracket height is made adjustable rather than fixed, allowing the securing edge to be positioned at the optimal height for each type of goods. For tall bottles, the bracket extends higher; for shorter items like eggs or butter, the bracket is positioned lower, providing secure containment for each goods type.
Solution Approach 2:
The door rack provides locally optimized containment by adjusting the bracket height to match the specific height requirements of the stored goods. Each goods type receives the appropriate level of securing without being over-constrained by uniformly high edges.
