Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cooling devices experience malfunctions and increased maintenance costs due to gaps formed in the insulation material during solidification, which can cause the sheet metal to collapse, especially at the ceiling, leading to reduced efficiency and user perception issues.
Innovation Solution
A regulating member with holes is placed within the insulation volume to split the insulation material into smaller pieces as it solidifies, minimizing air gaps and preventing collapses by controlling the flow of the material, allowing for the use of quick-solidifying polyurethane and reducing production time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If quick-solidifying polyurethane is used as the insulation material, then the body-insulation process is accelerated, but the number of gaps in the insulation material increases
Solution Approach 1:
The insulation material is divided into smaller pieces by passing through holes on the regulating members during filling. This segmentation prevents the material from forming large continuous gaps during quick solidification, allowing faster curing without sacrificing homogeneity.
2Manufacturing precision
If slow-solidifying polyurethane is used to prevent collapses on the surface, then gaps are reduced, but production slows down and efficiency decreases
Solution Approach 1:
By segmenting the insulation material through the regulating members with holes, the material fills more uniformly and solidifies without causing surface collapses. This allows the use of quick-solidifying material while maintaining surface quality.
3Loss of time
If insulation material is filled rapidly, then production time is reduced, but gaps and collapses occur more frequently
Solution Approach 1:
The regulating members with holes are installed beforehand in the insulation volume to pre-establish a flow control structure. This preliminary arrangement ensures that when insulation material is rapidly filled, it is automatically distributed uniformly through the holes, preventing gaps and collapses during fast filling operations.
