Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a common sealing gasket is used between the motor protection housing and the mixing chamber, then the device complexity is reduced, but the airtightness and waterproofness deteriorate due to displacement caused by drive motor vibrations
Solution Approach 1:
The sealing ring is divided into two distinct parts: a first sealing ring portion that seals between the motor protection housing and fixed ring, and a second sealing ring portion that seals between the evaporator and fixed ring. This segmentation allows each portion to independently address specific sealing requirements, preventing displacement-related leakage while maintaining structural simplicity.
Solution Approach 2:
The patent employs a flexible sealing ring made of elastic material that can deform to accommodate vibrations from the drive motor. This flexible membrane structure maintains reliable sealing contact despite relative movements, solving the waterproofness issue without requiring complex rigid sealing mechanisms.
2Ease of operation
If the evaporative cooling component and stirring component are connected together to stir the ice crystal mixture conveniently, then the ease of operation is improved, but the reliability deteriorates due to potential safety hazards from motor isolation requirements
Solution Approach 1:
The drive motor is extracted and isolated within the motor protection housing, separated from the mixing chamber containing the liquid. This extraction eliminates safety hazards while the sealing ring ensures functional connection is maintained through reliable sealing, allowing convenient operation without compromising safety.
Solution Approach 2:
The motor protection housing acts as an intermediary structure that physically separates the drive motor from the mixing chamber while maintaining functional connection through the sealing ring. This intermediary structure resolves the conflict between motor isolation for safety and operational convenience.
3Manufacturing precision
If the sealing gasket is provided as a flat structure, then the manufacturing precision requirement is reduced, but the airtightness deteriorates under vibration conditions causing displacement
Solution Approach 1:
The sealing ring is designed as a flexible elastic structure rather than a rigid flat gasket. This flexibility allows the sealing surface to adapt and maintain contact under vibration conditions, ensuring airtightness without requiring high manufacturing precision for flatness tolerance.
Solution Approach 2:
The sealing structure transitions from a static flat gasket to a dynamic flexible ring that can deform and adapt to relative movements caused by vibrations. This dynamic characteristic maintains sealing effectiveness under varying operating conditions without demanding high manufacturing precision.
