Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If conventional winding structures are used with winding connections formed on top of the insulated frame, then the motor can achieve basic winding functionality, but the space occupied by the motor system is increased and the volume cannot be minimized
Solution Approach 1:
The patent transitions from vertical winding connections (on top of the insulated frame) to lateral winding connections (along the axial direction at the side of the insulated frame). This dimensional change allows the winding connections to be integrated into the lateral slots of the insulated frame, eliminating the need for separate space on top and thereby reducing the overall motor volume.
Solution Approach 2:
The patent merges the winding connection function with the insulated frame structure by integrating the winding connections directly into the lateral slots of the insulated frame. This consolidation eliminates separate components and reduces the overall space occupation, directly addressing the volume reduction goal.
2Productivity
If manual winding methods are used to form winding coils and connections, then flexibility and adaptability are maintained, but labor time is excessive and manufacturing cost is high
Solution Approach 1:
The patent implements preliminary action by pre-forming the insulated frame with integrated lateral slots that are specifically designed to accommodate winding connections. This pre-prepared structure enables subsequent automated winding operations to proceed efficiently without requiring complex manual assembly, thereby reducing labor time and increasing productivity.
Solution Approach 2:
The patent replaces manual mechanical winding operations with automated winding mechanisms that can efficiently form winding coils and connections within the pre-designed lateral slots. This substitution of manual labor with automated systems directly addresses the productivity improvement and time reduction objectives.
3Weight of stationary object
If winding connections are formed on top of the insulated frame, then electrical connectivity is achieved, but the occupation space is big and insulation glue usage increases the total weight
Solution Approach 1:
The patent moves the winding connections from the vertical top surface to the lateral axial direction of the insulated frame. This dimensional relocation reduces the space occupation and minimizes the amount of insulation glue required, thereby reducing the total motor weight while maintaining electrical connectivity through the integrated lateral slot design.
4Volume of moving object
If complex winding structures are used to achieve proper phase connections, then electrical functionality is maintained, but the axial height is increased and volume reduction is hindered
Solution Approach 1:
The patent redistributes the winding connections along the axial direction at the sides of the insulated frame rather than stacking them vertically on top. This dimensional redistribution reduces the axial height requirement while maintaining all necessary phase connections, enabling volume reduction without sacrificing electrical functionality.
