Integrated Watch Crown-Pusher for Multi-Function Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing control devices for timepieces with multiple functions, such as winding and operating chronographs, often suffer from complex constructions that lead to sealing issues and lack aesthetic diversity.
Innovation Solution
A control device with a first actuation member moving translationally along axis X1 and a second actuation member moving translationally or rotationally along axis X2, integrated with a control member, allowing simultaneous operation of two functions with a unique appearance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a crown-pusher construction is used with nested independent control devices, then multiple functions can be operated, but the device complexity increases and sealing problems occur
Solution Approach 1:
The patent merges the crown and pusher functions into a single integrated control member. The control member can perform both rotational movement (crown function) and axial translation (pusher function) without requiring nested independent devices. This integration eliminates the complexity of multiple separate control mechanisms while maintaining multi-functionality.
Solution Approach 2:
The control member is designed as a universal element that performs multiple functions: it can rotate to operate the time setting mechanism and translate axially to operate the chronograph or other functions. This single multi-functional component replaces what would traditionally require separate specialized components.
2Adaptability or versatility
If a crown-pusher construction with nested independent control devices is used, then multiple functions can be operated, but sealing problems occur
Solution Approach 1:
By merging the crown and pusher into a single control member, the patent eliminates the need for nested independent devices that create sealing interfaces. The integrated design reduces the number of sealing surfaces required, as there is only one control member penetrating the case back rather than multiple nested components.
3Adaptability or versatility
If conventional multi-function control devices are used, then multiple functions can be operated, but aesthetic diversity is limited
Solution Approach 1:
The patent enables the control member to operate in two distinct dimensions: rotation around its axis and translation along its axis. This multi-dimensional operation capability allows for greater design flexibility and aesthetic diversity, as the control member can be shaped and styled differently while maintaining its dual functionality.

AI summary
The invention relates to a control device (1), for actuating at least two functions of a timepiece, comprising: a first actuating member, with main axis X1, intended to move in translation along its main axis X1 to actuate a first function, a control member (2) superimposed on the first actuating member, and a second actuating member intended to move along at least one axis X2 distinct from the main axis X1 to actuate a second function in response to an adapted displacement of at least a part of the control member (2), the second actuating member being integral with the control member (2).
