1Productivity
If traditional methods of securing circuit board within light bulb are used, then manufacturing process is simple, but manufacturing time increases and productivity decreases
Solution Approach 1:
The contact interface is divided into separate functional portions: first and second electrically conductive biasing portions for electrical connection, and a bridge portion for mechanical support. This segmentation allows each portion to be optimized independently, enabling faster assembly while maintaining both electrical and mechanical functions.
Solution Approach 2:
The invention merges electrical connection and mechanical positioning functions into a single integrated contact interface component. By combining the biasing portions (for electrical contact) and the bridge portion (for mechanical support) into one unit, the number of separate components and assembly steps is reduced, thereby increasing manufacturing productivity and reducing time loss.
2Stability of the object's composition
If circuit board is securely positioned within lamp base, then stability is improved, but manufacturing complexity increases
Solution Approach 1:
The bridge portion is designed to be resilient, allowing dynamic adjustment during assembly. This resilience enables the bridge portion to flex and adapt to slight variations in component dimensions during the insertion process, providing self-aligning capability that simplifies manufacturing while ensuring stable final positioning of the circuit board.
Solution Approach 2:
The resilient bridge portion provides self-aligning and self-adjusting functionality during assembly. The component automatically compensates for minor dimensional variations and positioning errors through its elastic deformation, eliminating the need for complex alignment mechanisms or precision adjustment procedures, thereby reducing assembly complexity while maintaining positioning stability.

Function Achieved in This Case
This solution reduces manufacturing time by facilitating a secure and efficient electrical connection between the circuit board and the lamp base, enhancing productivity and stability during the manufacturing process.
Implementation Method 1
The first resilient portion and the second resilient portion are substantially symmetrical about a centerline of the contact interface. The resilient bridge portion extends between the first resilient portion and the second resilient portion.

AI summary
An assembly includes a contact interface device, a lamp base and a circuit board. This device is connected to the circuit board and is used to bias the circuit board within the center of a cavity of a light bulb. This device contains two or more biasing portions that are connected to one another through a bridge portion. The biasing portions engage an interior threaded portion of the lamp base in order to lock into place and not allow the circuit board to move. The bridge portion allows the biasing portions to counteract one another and suspend the circuit board in the middle of the cavity of the light bulb.
