Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing incubators lack the capability to simulate pressure fluctuations, which are essential for mimicking the human body environment for cell culture, thereby limiting the biological activity and culture effectiveness of cells.
Innovation Solution
The incubator is equipped with a variable pressure apparatus comprising a cylinder body and a piston that allows for fluctuating or constant gas pressure input, controlled by a servo motor and transmission mechanism, with safety valves to manage pressure and maintain a stable culture environment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a constant pressure is applied into the incubator, then the culture effect is improved, but the ability to simulate human body environment is insufficient
Solution Approach 1:
The patent transforms the static constant pressure system into a dynamic pressure control system. The pressure control unit can adjust the internal pressure to fluctuate over time, specifically implementing sinusoidal pressure changes that simulate the pressure variations in the human body. This dynamic capability allows the incubator to maintain reliable culture conditions while simultaneously adapting to mimic physiological environments, resolving the contradiction between culture effectiveness and environmental simulation accuracy.
2Productivity
If the pressure in the incubator is increased above atmospheric pressure, then the culture effectiveness is improved, but the control complexity increases
Solution Approach 1:
The patent introduces a pressure control unit as an intermediary component between the power supply and the incubator chamber. This dedicated control unit manages the complex task of pressure regulation, including maintaining constant pressure and implementing sinusoidal fluctuations. By isolating the complexity into a specialized subsystem, the overall system can achieve enhanced culture effectiveness through superior pressure control without excessively complicating the entire incubator design.
Solution Approach 2:
The patent implements a pressure control system that can dynamically change pressure parameters according to different culture needs. The system can switch between maintaining constant elevated pressure and applying sinusoidal pressure variations, providing flexible parameter adjustment. This capability allows the incubator to optimize culture effectiveness through controlled pressure increases while managing system complexity through programmable parameter changes rather than requiring multiple physical systems.
