Fan Wire Trimming Module for Automated Stator Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The manufacturing process of thinner fans with high power and structural strength faces inefficiencies due to the lack of a securing structure for windings, leading to displacement and loosening during soldering, which hampers production efficiency and automation.
Innovation Solution
A fan wire trimming module comprising a lower and upper moldboard with locating bosses and holes, a fixing split, and a base plate with a bearing cup, allowing for secure engagement and tensioning of windings, preventing displacement and enabling automated production.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual trimming of wires is performed to complete successive steps, then production can be completed, but production efficiency is poor and automation is hindered
Solution Approach 1:
The patent applies preliminary action by pre-securing the winding wire ends to the stator core using a securing structure before the winding process. This preliminary securing prevents the need for manual trimming during subsequent steps, enabling automated production. The securing structure is prepared in advance and integrated into the stator core, so that when windings are wound and then removed, the wire ends are already positioned and secured, eliminating manual intervention.
2Reliability
If no securing structure is provided for fixing winding ends, then the stator structure remains simple, but windings are apt to displace and loosen during soldering
Solution Approach 1:
The patent merges the securing structure with the stator core by integrating the wire-securing portions directly into the stator core structure. Instead of adding separate, independent securing components, the securing features are combined with the existing stator core, thereby improving winding stability without significantly increasing overall structural complexity. This integration ensures that winding ends are firmly fixed during soldering while maintaining a relatively simple stator design.
3Volume of moving object
If thinned fan structure is designed for high power and structural strength, then product miniaturization is achieved, but manufacturing complexity increases
Solution Approach 1:
The patent applies preliminary action by pre-securing the winding wire ends to the stator core using a securing structure for thinned fans before the winding process. This preliminary securing prevents the need for manual trimming during subsequent steps, enabling automated production. The securing structure is prepared in advance and integrated into the stator core, so that when windings are wound and then removed, the wire ends are already positioned and secured, eliminating manual intervention.
