Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing simulation cabinets have complex designs that hinder optimal air flow and temperature homogeneity within the interior chamber, leading to inefficient temperature distribution.
Innovation Solution
A simulation cabinet design featuring a rear wall with ventilator openings and flow restrictors that guide air through openings into the interior chamber, ensuring a more homogenous temperature distribution by expanding and cooling the air before it enters, and optionally incorporating multiple flow restrictors, heating devices, and air guidance elements for improved air flow management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If air is introduced over the entire interior walls through wide areas, then temperature homogeneity is improved, but device complexity increases due to complicated air guidance structures
Solution Approach 1:
The interior wall is segmented into multiple regions with different air introduction characteristics. The front wall has a first air introduction structure with specific opening distribution, while the rear wall has a second air introduction structure with different characteristics. This segmentation allows each region to contribute differently to temperature homogeneity without requiring complex overall structure.
Solution Approach 2:
Different regions of the interior wall are given different air introduction properties. The front wall openings are distributed in a specific pattern, while the rear wall has a different opening arrangement. This local differentiation optimizes air flow distribution and temperature homogeneity without requiring complex global air guidance structures.
2Temperature
If wide area air introduction is used, then temperature distribution is improved, but air flow guidance complexity increases
Solution Approach 1:
The air introduction system is divided into multiple independent structures located at different walls. Each wall structure has its own opening pattern and air introduction characteristics, simplifying the overall air flow guidance while achieving uniform temperature distribution through coordinated operation of all segments.
Solution Approach 2:
Instead of using complex active air guidance mechanisms to achieve uniform distribution, the invention uses simple passive opening structures distributed throughout the walls. The uniform temperature distribution emerges naturally from the coordinated air introduction through these simple, distributed openings rather than from complex active control.
3Device complexity
If simple design is used, then device complexity is reduced, but air guidance effectiveness deteriorates
Solution Approach 1:
Each wall is equipped with air introduction openings with specific local characteristics optimized for its position. The front wall has a particular opening pattern, while the rear wall has a different pattern. This local optimization ensures effective air guidance at each location while maintaining overall structural simplicity.
Solution Approach 2:
The air introduction openings serve multiple functions simultaneously: they introduce air into the chamber, distribute it uniformly, and contribute to temperature homogeneity. This multi-functionality of simple opening structures achieves effective air guidance without requiring complex dedicated components for each function.
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 design achieves improved homogeneity of temperature inside the interior chamber by ensuring uniform air distribution and temperature consistency, simplifying the cabinet's structure while enhancing air guidance and heating efficiency.
Implementation Method 1
The flow restrictor causes a throttling of the air flowing through the flow restrictor. After flowing through the flow restrictor, the air expands. Thus, after flowing through the flow restrictor, here a lower pressure results for the air in reference to said air upstream said flow restrictor. The mean particle distance of the air components increases by said expansion, which results in a change of the air temperature.
