Problem
Existing push button devices for timepieces with inscriptions or motifs on their heads face challenges in achieving precise angular orientation during assembly, which affects the aesthetics of high-quality and luxury products.
Innovation Solution
A push button device with a cylindrical tube, a push button head, a return spring, and a sealing gasket, featuring a friction ring that rotates with the central shaft to adjust the angular orientation of the head, allowing for precise positioning of the logo or trademark relative to the watch case.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the push button device is assembled by screwing or pressing the tube into the watch case using known assembly methods, then the assembly process is simple and economical, but the push button head cannot be brought into a determined precise angular orientation with respect to the case
Solution Approach 1:
A friction ring is introduced as an intermediary component between the push button shaft and the tube. This friction ring can rotate independently and provides a controlled friction interface that allows for precise angular positioning of the push button head relative to the watch case during assembly, while maintaining a relatively simple assembly process
Solution Approach 2:
The friction ring is designed to be rotatable during assembly to allow angular adjustment of the push button head, and then locked in position through friction. This dynamic element enables precise angular orientation control without requiring complex positioning mechanisms or multiple assembly steps
2Manufacturing precision
If the push button head includes a logo or trademark that requires precise angular orientation, then the aesthetic quality of luxury timepieces is improved, but the known assembly methods cannot achieve the required positioning precision
Solution Approach 1:
The friction ring serves as a mediator between the push button assembly and the watch case, providing a controlled friction interface that enables precise angular positioning of the logo or trademark during assembly, while keeping the assembly process relatively simple and economical
Solution Approach 2:
The friction ring is pre-configured with specific friction characteristics that allow the push button head to be easily rotated into the desired angular position before final locking, enabling preliminary angular adjustment without requiring complex positioning tools or procedures
