Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual welding is used to connect coil connection ends to circuit board, then flexibility in operation is maintained, but production efficiency is low and error rate is high
Solution Approach 1:
The patent replaces manual welding operations with automated pick-and-place machine operations. The machine automatically picks up the motor stator structure and places it on the circuit board at precise locations, eliminating the need for manual positioning and welding, thereby significantly improving production efficiency and reducing errors
Solution Approach 2:
The motor stator structure incorporates built-in suction holes that enable the pick-and-place machine to automatically grip and position the component. This self-service feature allows the component to be easily handled by automated equipment without requiring additional fixtures or complex positioning mechanisms
2Manufacturing precision
If naked eye positioning is used for manual welding, then device complexity is low, but manufacturing precision is poor
Solution Approach 1:
The patent replaces manual visual positioning with an automated pick-and-place machine that uses machine vision or programmed coordinates to locate and position the motor stator structure precisely on the circuit board, achieving high welding position accuracy without complex manual positioning procedures
Solution Approach 2:
The built-in suction holes in the motor stator structure serve as intermediaries that enable the pick-and-place machine to accurately grip and position the component. These holes provide standardized attachment points that facilitate precise positioning while keeping the overall system relatively simple

AI summary
A motor stator locating method for locating a motor stator structure on a circuit board is disclosed. The motor stator structure includes a base and a contact pad set. The base is provided at a central portion thereof with a raised portion, which is wound around by a coil having a plurality of turns. The contact pad set is correspondingly attached to one side of the base opposite to the raised portion, and has a first and a second contact pad. The coil has two ends respectively connected to the first and the second contact pad. With these arrangements, the motor stator structure can be manufactured at largely improved production efficiency and reduced error rate.
