Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sample temperature control chambers for X-ray diffraction experiments are not suitable for compact benchtop X-ray devices due to their large size, weight, and requirement for external cooling connections, which violate safety regulations and complicate operation in fully protected devices.
Innovation Solution
A compact sample temperature control chamber with integrated heating and cooling elements, including an electrical resistance element and a Peltier element, allows for temperature control within a sealed environment without external connections, using active cooling and a control unit for precise temperature management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If external cooling circuits are used in temperature control chambers, then cooling performance is improved, but device portability and ease of operation deteriorate due to required external connections
Solution Approach 1:
The cooling circuit is merged with the temperature control chamber itself. The chamber housing contains integrated cooling channels that circulate coolant internally, eliminating the need for external cooling connections while maintaining effective cooling performance.
Solution Approach 2:
The temperature control chamber is designed to be self-sufficient with all necessary cooling components integrated within the chamber structure. The chamber serves its own cooling needs through internal coolant circulation, without requiring external cooling infrastructure.
2Temperature
If external cooling connections are provided, then temperature control capability is improved, but device complexity and safety compliance worsen due to additional connections in protected devices
Solution Approach 1:
The cooling functionality is merged into the chamber structure with cooling channels formed directly in the housing. This integration eliminates separate external cooling connections and reduces the number of components that require assembly and maintenance.
Solution Approach 2:
The cooling function is extracted from external systems and incorporated directly into the chamber design. By taking out the cooling circuit from external infrastructure and embedding it within the chamber, the device becomes self-contained and compliant with safety regulations for protected devices.
3Temperature
If large-sized temperature control chambers are used, then temperature control functionality is improved, but device compactness and portability deteriorate
Solution Approach 1:
The cooling channels are strategically positioned in specific regions of the chamber housing where heat transfer is most needed. The sample holder area and surrounding regions receive enhanced cooling through localized channel placement, achieving effective temperature control without requiring a uniformly large chamber volume.
Solution Approach 2:
The chamber design optimizes the dimensions and cross-sectional area of cooling channels to maximize heat transfer efficiency within a compact volume. By adjusting channel parameters such as diameter, length, and distribution density, effective cooling is achieved in a smaller overall chamber size.
