Existing devices for testing material properties, such as outgassing of volatile constituents, are complex and expensive to maintain due to the need for tightness in heating devices and frequent renewal of heating baths, making them difficult to handle and operate reliably.
Innovation Solution
A device with a solid metal block as a heat transfer medium, integrated with a vent valve connection in the coolant distribution unit for air removal, and an electrically operated heating source for controlled heat input, simplifies handling and ensures long-term stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a heating bath is used to heat material samples, then the material samples can be heated to specified temperatures, but the device becomes complex and requires frequent maintenance of tightness and bath renewal
Solution Approach 1:
The patent extracts the liquid bath medium from the heating system and replaces it with a solid heating block. This eliminates the need for maintaining liquidtight seals and frequent bath renewal while preserving the heating function. The solid heating block directly contacts the sample containers, providing stable temperature without the complexity of liquid bath management.
Solution Approach 2:
The heating block is designed as a simple, replaceable component that can be easily manufactured and replaced if needed. This approach replaces the expensive and complex liquid bath system with a simpler solid alternative that doesn't require the same level of maintenance or tightness requirements.
2Temperature
If a liquid heating bath is used, then heating can be provided, but regular renewal of the heating bath is required increasing maintenance costs
Solution Approach 1:
The liquid bath medium is completely removed from the system and replaced by a solid heating block. This extraction eliminates the need for periodic bath renewal and associated maintenance costs, while the solid block provides stable, reusable heating capability.
Solution Approach 2:
The heating block is designed as a simple, durable component that replaces the expensive and maintenance-intensive liquid bath system. It provides long-term reliable operation without the need for regular replacement or renewal.
3Temperature
If air enters the coolant circuit, then cooling efficiency decreases, but removing air requires complex procedures
Solution Approach 1:
The vent valve is pre-positioned at the highest point of the coolant circuit where air naturally accumulates. This preliminary positioning of the air removal mechanism allows air to be easily evacuated during system startup or maintenance without requiring complex procedures. The vent valve connection is integrated into the coolant distribution unit at the optimal location for air removal.
