Voice Coil Motor Base Assembly for Warp-Free Terminal Cutting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The shrinking size of voice coil motors poses a challenge in preventing terminal warping during the cutting process due to the lack of space for a pressing jig, which is typically used to stabilize the terminal.
Innovation Solution
The base assembly incorporates a first elastic piece connecting area with an engaging part that stabilizes the first terminal, allowing it to be cut without a pressing jig, thereby preventing warping and enabling a compact design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a pressing jig is used to prevent terminal warping during cutting, then terminal stability is improved, but device complexity and space requirements increase
Solution Approach 1:
The pressing function is merged with the base body structure itself. The base body includes a pressing cavity that directly contacts and presses the terminal during cutting, eliminating the need for a separate pressing jig. This integration maintains terminal stability while reducing device complexity and space requirements.
Solution Approach 2:
The base body serves its own pressing function through the pressing cavity. The structural design allows the base body to automatically stabilize the terminal during cutting without requiring external pressing equipment, making the system self-sufficient and reducing overall complexity.
2Stability of the object's composition
If a stepped part is added to the base body for pressing jig accommodation, then terminal stability during cutting is improved, but manufacturing complexity and space requirements increase
Solution Approach 1:
The pressing function is integrated into the base body through a pressing cavity rather than adding a separate stepped part. This merging approach maintains terminal stability during cutting while simplifying the base body structure and reducing manufacturing complexity compared to traditional stepped designs.
3Volume of moving object
If the voice coil motor size is reduced, then product compactness is improved, but space for pressing jig during cutting is reduced
Solution Approach 1:
The base body performs its own pressing function through the integrated pressing cavity, eliminating the need for external pressing jigs. This allows the voice coil motor to be miniaturized while maintaining ease of operation during the cutting process, as the pressing function is built-in rather than requiring additional space.
4Device complexity
If the base body structure is simplified to reduce space, then device compactness is improved, but terminal warping prevention capability is reduced
Solution Approach 1:
The pressing function is merged into the base body structure through a pressing cavity, allowing the base body to maintain terminal stability during cutting without requiring additional complex structures like stepped parts. This integration achieves both structural simplification and effective warping prevention.
