Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a large number of parts are used to create complex kinematics in watch movements, then the functionality and complexity of the watch is improved, but the energy consumption increases and the volume required increases
Solution Approach 1:
The patent combines multiple kinematic functions into a single integrated mechanism. The coupling mechanism integrates the driving rocker, driven rocker, and linkage elements into one unified structure that performs multiple functions simultaneously, reducing the total number of separate parts while maintaining complex functionality.
Solution Approach 2:
The coupling mechanism is designed as a multi-functional element that can transmit motion, transform rotational directions, and control kinematic relationships between different components. This universal mechanism replaces what would traditionally require multiple separate mechanisms, thereby reducing energy consumption while maintaining versatility.
2Adaptability or versatility
If a large number of parts are used to create complex kinematics in watch movements, then the functionality and complexity of the watch is improved, but the volume required within the watch movement increases
Solution Approach 1:
The patent combines multiple kinematic functions into a single integrated mechanism. The coupling mechanism integrates the driving rocker, driven rocker, and linkage elements into one unified structure that performs multiple functions simultaneously, reducing the total number of separate parts while maintaining complex functionality.
Solution Approach 2:
The linkage mechanism is designed with nested components where elements are arranged concentrically or in overlapping configurations. The connecting rod and rockers are positioned to utilize shared space, allowing the mechanism to achieve complex motion transformation within a minimized volume suitable for watch movements.
3Device complexity
If the rotation axis of the driven rocker is made parallel to the driving rocker axis, then the mechanical structure is simplified, but the ability to transmit motion efficiently between non-coplanar components is reduced
Solution Approach 1:
The patent introduces a non-parallel axis configuration where the driven rocker rotates about an axis that is offset and angled relative to the driving rocker axis. The linkage mechanism translates rotational motion from one axis to another through a three-dimensional arrangement, enabling efficient motion transmission between non-coplanar components while maintaining controlled complexity.

AI summary
The invention relates to a kinematic linkage mechanism (10) for a watch movement (60), intended to be arranged between an actuator (20) and a receiver (30), characterized in that it comprises a driving rocker (11) intended to be driven in rotation by the actuator (20) about an axis A1, a driven rocker (12) movable in rotation about an axis A2 not parallel to the axis A1, the driven rocker (12) being kinematically connected to the driving rocker (11) by a linkage module (13) configured so that the rotation of the driving rocker (11) causes the rotation of the driven rocker (12), the latter being intended to cooperate with the receiver (30) when it is driven in rotation.
