Double-Door Cooling Mechanism Layout for Narrower Door Gaps
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In cooling devices with two side-by-side doors, the overlapping door opening mechanisms create a gap between the doors, compromising insulation effectiveness and the external appearance.
Innovation Solution
The door opening mechanisms are designed with handles at the same height and support members positioned differently, allowing the handles to rotate in various orientations to minimize the gap between doors, using a cam shaft and transmission member to facilitate easy door separation while maintaining aesthetic appeal and reducing energy consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If door opening mechanisms are secured on the side wall of the door, then the door can be easily separated from the body, but the mechanisms overlap and cause a gap to be formed between the two doors
Solution Approach 1:
The support members are positioned at different vertical heights on adjacent doors, transitioning the problem from a horizontal overlap issue to a vertical dimension solution. This allows the door opening mechanisms to be offset vertically, eliminating horizontal gaps while maintaining ease of door separation operation.
2Loss of energy
If the gap between doors is reduced, then insulation effectiveness is improved, but the door opening mechanisms require more compact arrangement
Solution Approach 1:
By positioning support members at different vertical heights, the design reduces the horizontal gap between doors to less than the total thickness of the support members, improving insulation effectiveness while managing the complexity of mechanism arrangement through vertical offset.
3Shape
If handles are positioned at the same height, then aesthetic appearance is improved, but the support members must be positioned at different heights to avoid overlap
Solution Approach 1:
The support members are deliberately positioned asymmetrically at different vertical heights on adjacent doors, while the handles themselves remain at the same height for aesthetic purposes. This asymmetric support member positioning allows the symmetric handle appearance to be maintained while avoiding mechanism overlap.
