Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If individual heating elements are used for each cell, then temperature control of each cell is achieved, but the temperature adjustment becomes slow and complicated
Solution Approach 1:
The patent merges multiple individual heating elements into a single common heating channel that serves all dissolution cells simultaneously. This consolidation reduces the number of heating components from multiple individual elements to one shared heating system, thereby simplifying the overall device structure while maintaining temperature control capability across all cells.
Solution Approach 2:
The common heating channel is designed to serve multiple functions: it heats the dissolution medium in all cells simultaneously, provides uniform temperature distribution across different cells, and enables centralized temperature control. This multi-functional design eliminates the need for separate heating systems for each cell, reducing complexity while improving efficiency.
2Temperature
If individual heating elements are used for each cell, then each cell can be heated independently, but the temperature adjustment process becomes complicated
Solution Approach 1:
By combining all heating functions into a single common heating channel, the system enables simultaneous temperature adjustment across all cells through one control mechanism. This eliminates the need to adjust multiple individual heating elements separately, significantly simplifying the operation and accelerating the temperature adjustment process.
Solution Approach 2:
The heating system is segmented into a modular common channel design that allows for efficient heat distribution to multiple cells. This segmentation approach organizes the heating function in a way that simplifies control and adjustment, making the system easier to operate while maintaining independent temperature control capability for each cell through the shared channel.
3Temperature
If multiple individual heating elements are used, then each cell receives heating, but the overall system requires more components and maintenance
Solution Approach 1:
The patent consolidates multiple individual heating elements into one common heating channel that serves all dissolution cells. This merging reduces the total number of heating components from many individual elements to a single shared system, thereby simplifying the device structure, reducing maintenance requirements, and lowering component costs while maintaining uniform temperature distribution across all cells.
4Device complexity
If a common heating channel is used, then the system becomes simpler, but temperature control precision for each cell may be compromised
Solution Approach 1:
The common heating channel is designed with local quality variations that allow each cell to receive appropriate heating according to its specific requirements. The channel structure incorporates features such as varying distances from the heat source, localized insulation, or adjustable flow rates to different cells, enabling precise temperature control for each cell while maintaining the simplicity of a shared heating system.
Solution Approach 2:
The system incorporates temperature sensors and control mechanisms that continuously monitor the temperature in each cell and provide feedback to the common heating channel. This feedback loop allows the single heating system to dynamically adjust heat distribution to maintain precise temperature control for each individual cell, overcoming the potential precision loss from using a shared heating channel.
