Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the riveting member is arranged on two sides of the connection part between the resilient sheet and the terminal, then the connection effect between the resilient sheet and the terminal is improved, but the degree of freedom of design is reduced and the device complexity increases
Solution Approach 1:
The patent extracts the riveting member from the resilient sheet structure and integrates it into the terminal component. The terminal now includes a riveting member that protrudes from the resilient sheet connection region, allowing the resilient sheet to be directly riveted to the terminal without requiring separate riveting members on both sides of the connection part. This reduces design complexity while maintaining connection stability.
Solution Approach 2:
The patent merges the riveting member with the terminal structure, making the terminal a multi-functional component that both provides electrical connection and serves as the riveting anchor. This integration eliminates the need for separate riveting components and reduces the overall device complexity while maintaining reliable electrical connection.
2Ease of manufacture
If the riveting position on the resilient sheet connection region is fixed, then the manufacturing process is simplified, but the riveting position cannot be adjusted according to the height of the terminal, affecting connection stability
Solution Approach 1:
The patent makes the riveting position dynamic by allowing the terminal to be positioned at different heights on the resilient sheet connection region. The riveting member on the terminal can be riveted at any position along the resilient sheet, enabling adjustment according to terminal height variations. This dynamic positioning capability ensures stable electrical connection while maintaining ease of manufacture through a simple riveting process.
3Reliability
If the terminal height is relatively high, then the electrical connection capability is improved, but the fixed riveting position cannot correspond to the terminal height, causing instability
Solution Approach 1:
The patent enables dynamic adjustment of the riveting position along the resilient sheet connection region to match different terminal heights. The resilient sheet can be riveted at any position on the terminal, allowing the system to adapt to high terminals while maintaining stable electrical connection. This resolves the conflict between electrical connection capability and connection stability.

AI summary
Provided are a resilient sheet structure and a voice coil motor. The resilient sheet structure includes a connection piece and a resilient sheet. The resilient sheet includes a fixed portion, a beam, and a fitting portion. The fixed portion is electrically connected to the connection piece and is configured to be connected to the base assembly of a voice coil motor. One end of the beam is connected to the fixed portion, and the other end of the beam can rotate around one end of the beam to enable the beam to be at an included angle with a preset plane. The fitting portion is connected to the other end of the beam, and the fitting portion can rotate around the beam to enable the fitting portion to be parallel to the preset plane.
