Voice Coil Motor Base Assembly With Engaging Terminal Fixation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The shrinking size of voice coil motor products poses a challenge in preventing terminal warping during the cutting process due to the lack of space for a pressing jig, which is essential for maintaining the stepped part design that prevents warping.
Innovation Solution
The base assembly of the voice coil motor incorporates a first elastic piece connecting area with a lower elastic piece and a first terminal that includes an engaging part extending from the elastic piece connecting area, allowing the terminal to be stably fixed and cut without a pressing jig, thus preventing warping and eliminating the need for a stepped part.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a stepped part is added to the base body to provide space for a pressing jig, then the terminal can be prevented from warping during cutting, but the device size increases and space is consumed
Solution Approach 1:
The terminal itself provides the pressing function through its own engaging part that fits into the base body, eliminating the need for an external pressing jig and stepped part structure
Solution Approach 2:
The engaging part of the terminal and the corresponding fitting structure in the base body are merged into a single integrated design, combining the terminal fixation and warping prevention functions into one structure
2Volume of moving object
If the base assembly size is reduced to meet product miniaturization, then the product becomes more compact, but the stepped part design cannot be retained, causing terminal warping during cutting
Solution Approach 1:
The terminal's engaging part automatically provides the necessary support and positioning during cutting without requiring additional space-consuming structures like stepped parts
Solution Approach 2:
Instead of adding a stepped part to the base body to support the terminal, the design inverts the approach by having the terminal's engaging part directly fit into the base body to provide mutual support and fixation
3Manufacturing precision
If a pressing jig is used to press the terminal during cutting, then warping is prevented, but the device complexity increases and additional components are required
Solution Approach 1:
The terminal and base body structure themselves provide the pressing and support functions through their engaging part and fitting structure, eliminating the need for external pressing jigs
Solution Approach 2:
The pressing function is extracted from the base body structure and integrated directly into the terminal's engaging part, removing the need for separate pressing jig components
