Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In semiconductor manufacturing, existing temperature and humidity control systems face challenges in maintaining smooth fluid flow and preventing gas lockages, which can disrupt the temperature and humidity control of heat-producing equipment, affecting the quality of products.
Innovation Solution
A temperature and humidity controlling system comprising a condenser, tank, pipe, and air duct, where the cooled cooling fluid flows between the pipe and air duct, allowing gas to escape through the air duct while preventing fluid accumulation, ensuring continuous fluid flow and avoiding gas lockages.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If cooled cooling fluid flows through a conventional pipe system, then temperature control is achieved, but gas lockages occur and disrupt fluid flow
Solution Approach 1:
The pipe system is segmented into multiple sections with drainage devices installed at low points. This segmentation allows gas pockets to be isolated and drained from specific sections rather than affecting the entire system, maintaining continuous fluid flow while eliminating gas lockage disruptions.
Solution Approach 2:
The drainage device acts as an intermediary component between the pipe and the environment. It provides a controlled pathway for gas to escape while preventing liquid leakage, serving as a mediator that resolves the conflict between maintaining sealed temperature control and allowing gas venting.
2Object-generated harmful factors
If conventional drainage methods are used, then gas can escape, but cooling fluid may leak along with the gas
Solution Approach 1:
The drainage device maintains a homogeneous sealing interface between the pipe interior and exterior. The seal ensures that the same conditions apply throughout the drainage opening, preventing differential pressure from causing fluid leakage while still allowing gas to pass through when pressure exceeds the seal's holding capacity.
Solution Approach 2:
The drainage device exploits the parameter difference between gas and liquid phases. By designing the seal with specific pressure characteristics, it allows the lower-density gas phase to escape while the higher-density liquid phase remains contained, utilizing phase parameter differences to achieve selective drainage.
3Reliability
If the drainage device is installed at every low point, then gas lockage is prevented, but device complexity increases
Solution Approach 1:
The drainage device is designed as a universal component that can be installed at any low point in the pipe system. This multi-functional design allows a single standardized device to serve multiple drainage locations, reducing overall system complexity compared to using different specialized components at each location.
Solution Approach 2:
Rather than installing drainage devices at every possible low point, the system uses partial action by strategically placing devices only at critical locations where gas accumulation would most severely impact temperature and humidity control. This selective approach balances reliability improvement with complexity minimization.
