Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple samples are treated simultaneously in a common furnace chamber, then productivity increases, but contamination from volatile compounds affects measurement precision
Solution Approach 1:
The furnace chamber is divided into multiple independent zones, each equipped with its own temperature sensor. This segmentation allows simultaneous treatment of multiple samples at different temperatures while preventing cross-contamination between zones, thereby maintaining measurement precision for each sample independently.
2Device complexity
If a single temperature sensor is used for the entire furnace chamber, then device complexity is reduced, but manufacturing precision of temperature distribution deteriorates
Solution Approach 1:
Each zone within the furnace chamber is equipped with its own temperature sensor, enabling localized temperature measurement and control. This ensures that each region maintains the precise temperature required for specific thermal treatments, achieving uniform temperature distribution across different zones despite the increased number of sensors.
3Loss of substance
If volatile compounds are allowed to escape freely, then loss of substance is reduced, but harmful factors increase due to contamination of other samples
Solution Approach 1:
The furnace chamber is divided into sealed zones that prevent volatile compounds from migrating between sample locations. Each zone can be independently vented or controlled, allowing volatile compounds to be managed within confined spaces without contaminating other samples, thus reducing both substance loss and harmful contamination effects.
4Measurement precision
If temperature sensors are positioned close to samples, then measurement precision improves, but device complexity increases due to positioning requirements
Solution Approach 1:
The temperature sensors are integrated into the furnace structure itself, such as embedding them in the chamber walls or ceiling. This merging of sensing elements with the structural components eliminates the need for separate positioning systems while maintaining close proximity to samples for accurate temperature measurement.
