Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The assembly of three-dimensional triangular iron cores is hindered by the weak supporting strength of amorphous strip materials, leading to deformation and poor assembly quality due to the weight of the iron core.
Innovation Solution
An assembly device with iron core driving devices, including a support member with a sliding device and electromagnets, allows for controlled movement and positioning of the iron cores, preventing self-supported gravity and facilitating precise assembly by using guide rails and a turnover device for upright and flat orientations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the iron core is placed upright during assembly, then the assembly process can proceed, but the weight of the iron core causes the strip material at the bottom to be pressed and deformed
Solution Approach 1:
The patent employs electromagnets to generate magnetic force that counteracts the gravitational force acting on the iron core. The electromagnets are positioned to provide upward magnetic attraction that balances the downward weight of the iron core, preventing deformation of the strip material at the bottom while allowing the core to remain in an upright position for assembly.
Solution Approach 2:
The patent introduces electromagnets as an intermediary force between the iron core and the supporting structure. Instead of direct mechanical contact that causes deformation, the electromagnets mediate the support by providing magnetic field-based holding force, allowing the iron core to be positioned and assembled without direct physical contact that would press and deform the strip material.
2Manufacturing precision
If the iron core is placed flat during assembly, then the strip material deformation is avoided, but the assembly process becomes more complex requiring turnover devices
Solution Approach 1:
The patent makes the support surface dynamic by using electromagnets that can actively adjust their holding force and position. The electromagnets can switch between holding the iron core in a flat position during initial assembly and transitioning to support it in an upright position, eliminating the need for separate turnover devices and fixed support structures.
Solution Approach 2:
The patent replaces complex mechanical turnover devices and fixed support structures with an electromagnetic field-based system. The electromagnets can remotely hold and reposition the iron core without mechanical contact, substituting a simple electromagnetic system for what would otherwise require complex mechanical linkages, pivots, and support platforms.
