Stator Lead-Out Pin Integration for Simpler Fluid Driver Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge of electrically connecting the energized end of a stator assembly with an external power source and simplifying the assembly process in a fluid driving apparatus is not adequately addressed by existing technologies.
Innovation Solution
A fluid driving apparatus incorporating a stator assembly, a limiting member, and a conductive member, where the conductive member is partially embedded in the limiting member, which is injection molded, allowing for a fixed arrangement that facilitates easy connection to an external power source, with the conductive member having a first connecting end to the stator assembly and a second connecting end as a pin end for external power source connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate components are used for electrical connection and structural support, then functional reliability is improved, but assembly complexity increases
Solution Approach 1:
The patent combines the conductive member (for electrical connection) and the limiting member (for structural support and positioning) into a single integrated component. The conductive member is embedded within the limiting member, creating a unified structure that performs both electrical and mechanical functions simultaneously, thereby simplifying assembly while maintaining reliability
Solution Approach 2:
The limiting member serves multiple functions: it provides structural support, positions the conductive member, and acts as an insulating barrier. The conductive member simultaneously provides electrical connection and is mechanically constrained by the limiting member. This multi-functionality reduces the total number of components needed
2Reliability
If multiple separate parts are used for electrical connection, then electrical reliability is improved, but manufacturing cost increases
Solution Approach 1:
By embedding the conductive member within the injection-molded limiting member, the patent reduces the number of separate manufacturing processes and assembly steps. The limiting member can be molded with the conductive member already in place, eliminating the need for separate assembly operations and reducing manufacturing costs while maintaining electrical reliability

AI summary
A fluid driving apparatus includes a stator assembly, a limiting member and at least one conducting member, at least part of the conducting member and the limiting member are arranged in a limited or fixed manner; the conducting member includes a first connection end and a second connection end, the first connection end is electrically connected to the stator assembly, and the second connection end may be used as a pin end when electrically connected to an external power source, so that the stator assembly and the external power source may be electrically connected by means of the conducting member; and the conducting member is partially embedded in the limiting member, and the limiting member is an injection-molded member. The described manner helps to lead out the energized end of the stator assembly, so that the led-out energized end may be used as a pin of an external interface.
