Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a solid-solid direct-heating structure with reaction cup clampers is used, then temperature stability and heating speed are improved, but the structure becomes complex and it becomes difficult to arrange the heat source
Solution Approach 1:
The reaction disc body is divided into an upper reaction disc and a lower reaction disc that are detachably connected. This segmentation allows the heater to be arranged in the hollow cavity of the lower reaction disc, simplifying the overall structure while maintaining the solid-solid direct-heating capability and temperature stability.
Solution Approach 2:
The heater is positioned in the hollow cavity of the lower reaction disc, utilizing the vertical dimension and the space within the disc structure. This dimensional arrangement simplifies the structure by integrating the heat source within the reaction disc body itself, eliminating the need for complex external clamping mechanisms.
2Reliability
If reaction cups are clamped by separate clampers assembled to the bottom plate, then the structure provides temperature control, but the structure becomes complex and maintenance becomes difficult
Solution Approach 1:
The reaction disc is segmented into upper and lower detachable parts, allowing easy access to the heater and internal components for maintenance while preserving the reliable solid-solid direct-heating function.
Solution Approach 2:
The heater is extracted from the traditional position and placed within the hollow cavity of the lower reaction disc. This extraction simplifies maintenance by making the heater easily accessible while maintaining effective thermal contact with the reaction cups for reliable temperature control.
3Device complexity
If an integral ring structure reaction disc body is used with heater in hollow cavity, then structure is simplified and heater arrangement is easy, but temperature fluctuation must be controlled
Solution Approach 1:
Heat-insulating materials are applied locally at specific positions on the reaction disc body to reduce heat loss and temperature fluctuation. This localized insulation maintains temperature stability while preserving the simplicity of the integral ring structure and easy heater arrangement.

AI summary
The present invention discloses a solid-solid direct-heating reaction disc arrangement comprising a reaction disc body, clampers, a heater and a driving plate. Holding slots for receiving reaction cups are formed axially through the reaction disc body at constant intervals. The clampers are mounted to the bottom surface of the reaction disc body and each comprise an upper clamper and a lower clamper which are fastened together. The bottom surfaces of the reaction cups rest on the upper clamper. The heater is sandwiched between the upper and lower clampers for heating the reaction disc body and the reaction cups. The driving plate is mounted to a supporting plate of the reaction disc body. By arranging the reaction disc body, the clampers, the heater and the driving plate in a receiving chamber defined by a cover and an insulation casing, a closed temperature control system is formed.
