A cooling device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cooling device holders cause insulation weakening and space occupation issues due to deformations on the side walls and protrusions into the cooling volume, especially when not in use.
Innovation Solution
A 'L' shaped holder with pivotable connections that can be folded under the shelf, utilizing pins and springs for secure and space-efficient storage, and a guardrail for object stability, allowing the holder to occupy minimal space when not in use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If holders are secured to the side wall of the cooling device body, then the holder can be firmly attached and support objects, but deformations formed on the side walls for mounting cause sealing problems and weaken the insulation
Solution Approach 1:
The holder is extracted from the cooling device body and repositioned to be suspended from the shelf. This eliminates the need for deformations on the side walls, thereby preserving the insulation integrity while maintaining holder attachment strength through the shelf-mounted pivot connection.
2Reliability
If holders are suspended under the shelf and extend into the cooling volume, then the holder is detachable and does not cause insulation problems, but the holder occupies space when not in use
Solution Approach 1:
The holder is designed with dynamic folding capability, allowing it to transition between an extended position for use and a folded position for storage. The pivot connection enables the holder to be folded parallel to the shelf surface, reducing the occupied volume when not in use while maintaining insulation integrity.
3Volume of moving object
If the holder is designed to be folded under the shelf, then the holder occupies minimal space when not in use, but the holder requires pivotable connections and linkage points that increase device complexity
Solution Approach 1:
The holder is segmented into distinct components (holder body, hanger, pivot connection, linkage points) that can move independently relative to each other. This segmentation enables the folding mechanism while keeping each component relatively simple in design.
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
The holder effectively reduces space usage within the cooling device, maintains insulation integrity, and ensures easy access to the interior volume by folding under the shelf, enhancing the device's usability.
Implementation Method 1
springs are provided on the pins. The springs maintain the holder to change to the open position softly
Implementation Method 2
the holder comprises more than one pin providing the hanger to be rotatably secured to the base
