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 waterproofness and airtightness deteriorate due to displacement caused by motor vibrations
Solution Approach 1:
The sealing ring is divided into multiple functional segments: an inner sealing portion for sealing against the fixed ring, an outer sealing portion for sealing against the motor protection housing, and a connecting portion linking them. This segmentation allows each part to perform its sealing function independently, ensuring reliable waterproofness even under vibration without requiring an overly complex integrated structure.
Solution Approach 2:
The inner sealing ring is nested within the sealing chamber formed by the outer sealing portion, front end face, and inner sealing ring. This nested configuration allows the sealing structures to be compactly arranged while maintaining multiple sealing interfaces, achieving reliable sealing without significantly increasing overall device complexity.
2Ease of operation
If the evaporative cooling component and stirring component are connected together, then the ease of operation is improved, but the safety deteriorates due to potential water leakage to the drive motor
Solution Approach 1:
The sealing ring applies local quality enhancement at critical sealing interfaces: the inner sealing portion with its extended inner sealing portion abuts against the fixed ring for enhanced sealing, while the outer sealing portion seals against the motor protection housing. This localized sealing enhancement protects the drive motor from water leakage while maintaining the connected structure for ease of operation.
3Manufacturing precision
If a flat sealing gasket structure is used, then the manufacturing precision requirement is reduced, but the airtightness deteriorates under vibration and displacement
Solution Approach 1:
The sealing ring employs curved surfaces instead of flat surfaces: the inner sealing ring has a circular cross-section that abuts against the fixed ring, and the outer sealing portion has a curved sealing surface against the motor protection housing. These curved surfaces provide better sealing contact and compensate for minor dimensional variations, achieving reliable airtightness without requiring extremely high manufacturing precision.
Solution Approach 2:
The sealing ring utilizes elastic material properties to change its dimensional parameters dynamically. The elastic portion can deform to accommodate slight displacements and maintain sealing contact, allowing the sealing structure to adapt to vibration and displacement while maintaining airtightness without requiring ultra-precise manufacturing tolerances.
