Coaxial Multifunction Corrector for Timepiece Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current timepieces face challenges in providing a simple and elegant user interface for selecting and modifying various functions, such as time, date, and chronograph, due to the need for multiple push-buttons and complex manipulation methods, which complicate user experience and aesthetic design.
Innovation Solution
A coaxial multifunction corrector device with a single external control member, comprising a pusher and control button that can rotate to select functions, driving a control rod with a pinion meshing with a rack, allowing for clear function identification and activation without additional control members on the caseband.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If multiple push-buttons are used to control different functions, then the functionality and ease of operation are improved, but the device complexity and aesthetic quality deteriorate
Solution Approach 1:
The single control member is designed to perform multiple functions including time correction, date correction, and chronograph control through different manipulation modes (rotation, pushing, pulling). This multi-functional design eliminates the need for multiple separate push-buttons while maintaining comprehensive control capabilities
Solution Approach 2:
The control member incorporates dynamic movement capabilities with rotational positions and push/pull actions that activate different functions. The intermediate position during pulling allows for additional functions like alarm setting, creating a dynamic control interface that adapts to different operational needs
2Ease of operation
If multiple push-buttons are used to control different functions, then the ease of operation is improved, but the aesthetic quality and device simplicity deteriorate
Solution Approach 1:
The single control member serves as a universal control interface for all timepiece functions, maintaining a clean and elegant case design without multiple protruding buttons. This preserves the aesthetic quality while providing comprehensive operational control through a unified interface
3Adaptability or versatility
If complex manipulation methods are used, then the functionality is improved, but the ease of operation and user experience deteriorate
Solution Approach 1:
The control member operations are segmented into distinct manipulation types (rotation for time, pushing for date, pulling for alarm) that are intuitively associated with different functions. This segmentation provides clear tactile and visual feedback, making the complex functionality easier to operate and understand

AI summary
The device has a drive pinion with a contrate toothing secured directly or indirectly to a control stem, where the control stem is secured to a control button (15). A rack with a toothing meshes with the drive pinions. A rotation of the control button positions the end of a driven arm of a lever opposite a function corrector and set of applications of pressure on a pusher (10) activates the selected function, or alters the selected function, or activates and alters the selected function by causing movement of the rack.
