Solution Overview
Problem
Existing heating reaction containers face challenges in maintaining a sealed state at high temperatures, leading to material loss and deterioration due to vaporization and oxidation, and require complex structures to manage pressure changes during reactions.
Innovation Solution
A heating reaction container design featuring three members with specific thermal expansion coefficients and contact surfaces that seal through thermal expansion, allowing for a simple and cost-effective repeated use by ensuring the container remains sealed during heating and easy to disassemble after cooling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a reaction container is sealed to prevent material loss and deterioration during heating, then material preservation is improved, but the container structure becomes more complex to manage pressure changes and maintain sealing at high temperatures
Solution Approach 1:
The container is divided into multiple members (first member, second member, third member) that can be assembled and disassembled separately. Each member has specific functions: the first member forms the reaction space, the second member seals the opening, and the third member closes the space. This segmentation allows for simpler individual components while achieving reliable sealing when assembled.
Solution Approach 2:
The sealing mechanism utilizes thermal expansion parameter changes. The contact surfaces are designed with specific thermal expansion coefficients where the second member has a higher thermal expansion coefficient than the first member. When heated, the second member expands more, causing the contact surfaces to press tightly together and form a seal. This eliminates the need for complex mechanical sealing structures.
2Reliability
If a complex sealing structure is used to maintain sealed state at high temperature, then sealing reliability is improved, but manufacturing cost and maintenance difficulty increase
Solution Approach 1:
The invention uses thermal expansion parameter differences between materials to achieve sealing. The second member is made of material with higher thermal expansion coefficient than the first member, so when heated, it automatically presses against the first member's contact surface to seal. This simple parameter-based approach replaces complex mechanical sealing structures, reducing manufacturing cost and complexity.
Solution Approach 2:
The sealing mechanism is self-activating through thermal expansion. When the container is heated for reaction, the temperature increase automatically causes the second member to expand and press against the first member, creating the seal without requiring external actuation or complex control systems. This self-service mechanism reduces manufacturing and maintenance costs.
3Reliability
If a sealed container structure is used to prevent vaporization and oxidation, then material preservation is improved, but the container becomes difficult to disassemble after reaction
Solution Approach 1:
The sealing state of the container is dynamic rather than static. At high reaction temperatures, the second member expands and presses tightly against the first member to maintain sealing. Upon cooling after reaction, the second member contracts and the contact surfaces separate, automatically releasing the seal and allowing easy disassembly. This dynamic behavior based on temperature changes solves the contradiction between sealed operation and easy disassembly.

Function Achieved in This Case
The container effectively maintains a sealed environment at high temperatures, preventing material loss and deterioration, and allows for repeated use with reduced maintenance and operational costs by using a second member with a simple structure that can be easily replaced.
Implementation Method 1
α1, α2, and α3 satisfy a relation of α3>α2>α1, where α1 represents a thermal expansion coefficient of the first material, α2 represents a thermal expansion coefficient of the second material, and α3 represents a thermal expansion coefficient of the third material. A gap is present at least one of between the first contact surface and the second contact surface and between the third contact surface and the fourth contact surface before heating of the reaction raw material, the space being sealed, through the heating, by the first contact surface coming into intimate contact with the second contact surface and by the third contact surface coming into intimate contact with the fourth contact surface.

AI summary
Heating reaction container comprises: a first member; a second member; and a third member. An opening is closed by the second member being detachably fitted in the first member and by the third member being detachably fitted in the second member. α1, α2, and α3 satisfy a relation of α3>α2>α1, α3=α2>α1, or α3>α2=α1, where α1 represents a thermal expansion coefficient of a first material of the first member, α2 represents a thermal expansion coefficient of a second material of the second member, and α3 represents a thermal expansion coefficient of a third material of the third member. A gap is present before heating, and a space is sealed, through the heating, by a first contact surface coming into intimate contact with a second contact surface and by a third contact surface coming into intimate contact with a fourth contact surface.
