Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If separate cooling means and heating means are provided for both cooling water circuit and cutting water circuit, then temperature control precision is improved, but apparatus size increases
Solution Approach 1:
The patent combines the cooling water circuit and cutting water circuit into a shared system. The cooling water that has cooled the motor is reused to cool the cutting water through a heat exchanger, eliminating the need for separate cooling means for each circuit. This merging approach reduces apparatus size while maintaining temperature control through the integrated heat exchange mechanism.
Solution Approach 2:
The cooling water circuit serves multiple functions: it cools the motor and simultaneously cools the cutting water through the heat exchanger. The heating means also serves both circuits by heating the cooling water, which then heats the cutting water. This multi-functionality allows a single set of cooling and heating components to manage temperature for both water circuits, reducing overall apparatus size.
2Adaptability or versatility
If multiple cooling means and heating means are provided, then temperature adjustment capability is improved, but device complexity increases
Solution Approach 1:
The patent merges the temperature control systems of the cooling water circuit and cutting water circuit into a unified system. The same cooling means and heating means are used for both circuits, with temperature control achieved through the heat exchanger that transfers thermal energy between the two water streams. This reduces device complexity by eliminating redundant components while maintaining comprehensive temperature adjustment capability.
Solution Approach 2:
The heat exchanger acts as an intermediary device that enables thermal energy transfer between the cooling water and cutting water. This intermediary mechanism allows the single set of cooling and heating means to effectively control temperatures in both circuits without requiring direct separate control systems, thereby simplifying the overall device architecture.
3Reliability
If separate cooling circuits are used for motor cooling and cutting water cooling, then cooling effectiveness is improved, but apparatus size increases
Solution Approach 1:
The heat exchanger serves as an intermediary that enables effective cooling transfer from the motor cooling water to the cutting water. This allows the cooling effectiveness achieved by dedicated motor cooling to be transferred to the cutting water circuit without requiring a separate dedicated cooling system for the cutting water, thereby reducing apparatus size while maintaining cooling effectiveness.
Solution Approach 2:
The cooling water that has absorbed heat from the motor serves to cool the cutting water through the heat exchanger, effectively making the cooling system self-sufficient. The thermal energy removed from the motor is automatically utilized to cool the cutting water, eliminating the need for additional external cooling resources and reducing overall apparatus size.
