Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a stretching structure motor housing is used, then the motor can accommodate the stator, vibrator and elastic support member, but the forming process becomes more complicated and processing difficulty increases
Solution Approach 1:
The motor housing is divided into a first lateral housing and a second lateral housing, which are disposed at two ends of the motor housing respectively. Each lateral housing comprises multiple lateral plates (first lateral plate, second lateral plate, third lateral plate, fourth lateral plate, fifth lateral plate, sixth lateral plate) that are perpendicular to each other, forming a modular segmented structure that simplifies manufacturing while maintaining structural integrity
Solution Approach 2:
The lateral plates serve multiple functions: they form the housing structure, provide mounting surfaces for the stator and vibrator, create the closed space for accommodating components, and establish the overall motor housing configuration without requiring complex stretching operations

Solution Approach 2:
Instead of using a traditional stretching structure that requires complex forming operations, the patent inverts the approach by using perpendicular plates joined together to form the housing. This inverted construction method from stretching to plate assembly significantly reduces processing difficulty and cost
