Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a set of levers is used to arrange the control member remotely from the mechanism, then the control member can be positioned away from the mechanism, but the dimensions of the watch case significantly increase
Solution Approach 1:
The connecting member rotates about the horological movement, utilizing rotational motion in a different dimensional approach to transmit force. This allows the control member to be positioned remotely while maintaining a compact watch case by using angular displacement rather than linear extension.
Solution Approach 2:
The connecting member acts as an intermediary element between the input control member and the output control member. It rotates about the horological movement to transmit the actuating force, enabling remote control without requiring a complex lever system that would increase case dimensions.
2Ease of operation
If existing remote control solutions are used, then the control member can be offset from the mechanism, but the design must be significantly adapted for each scenario based on dimensions and geometry
Solution Approach 1:
The connecting member is designed to rotate about the horological movement and can be driven by the input control member in various positions. This universal design allows the same connecting member mechanism to handle different scenarios and geometries without requiring significant design adaptations for each specific application.
Solution Approach 2:
The connecting member is configured to rotate dynamically about the horological movement, allowing it to adapt to different positions and geometries. This dynamic rotational capability provides flexibility in designing watches with varying middle dimensions and control member positions without complicating the overall design.
3Device complexity
If control members are arranged in the immediate vicinity of the mechanisms, then the design is simple, but the control member cannot be positioned remotely
Solution Approach 1:
Instead of extending the control member linearly away from the mechanism (which would increase complexity), the connecting member rotates about the horological movement. This rotational approach in a different dimensional space allows remote positioning while maintaining design simplicity.
Solution Approach 2:
The connecting member serves as a simple intermediary that rotates about the horological movement to transmit force from the input control member to the output control member. This single rotational element provides remote positioning capability without introducing complex mechanical systems.

Implementation Method 1
The connecting member is intended to be arranged such that it can rotate about the horological movement and being configured such that it can be driven in rotation by the input control member when the latter is acted upon, and to cause the output control member to move during this rotation.
