Integrated Timepiece Correction Modules for Single-Opening Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The multiplication of correction devices in timepieces poses layout, aesthetic, and sealing problems due to the increased number of openings required for integrating multiple functions, particularly in mid-range and top-range watches.
Innovation Solution
A multifunction correction device that integrates a primary and secondary correction module within a single cylindrical body, allowing operation of multiple functions through a single opening in the watch case, minimizing the number of openings and maintaining a sleek design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple separate correction devices are integrated into the timepiece case to control multiple complications, then the functionality and versatility of the timepiece is improved, but the number of openings in the case increases leading to layout problems, aesthetic issues, and sealing difficulties
Solution Approach 1:
The patent combines multiple separate correction devices into a single integrated correction device. The device includes a first correction module with a first control member for controlling a first complication, and a second correction module with a second control member for controlling a second complication. Both modules are housed within a single case opening, merging what would traditionally require multiple separate openings into one unified structure.
Solution Approach 2:
The correction device is designed as a universal control unit that can manage multiple complications through its multiple control members. Each control member is associated with a specific control stem that can operate different complications, allowing a single device to perform the functions of multiple separate correction devices.
2Adaptability or versatility
If multiple separate correction devices are used to control multiple complications, then the versatility of the timepiece is improved, but the aesthetic appearance deteriorates due to multiple openings in the case middle
Solution Approach 1:
The patent merges multiple correction devices into a single integrated unit with a unified housing structure. This consolidation reduces the visual disruption to the case middle by replacing multiple separate openings with one integrated opening, thereby preserving the aesthetic appearance while maintaining full functionality.
3Adaptability or versatility
If multiple separate correction devices are integrated into the case, then the functionality for controlling complications is improved, but sealing problems worsen due to the multiplication of openings
Solution Approach 1:
The patent consolidates multiple correction devices into a single integrated housing that requires only one opening in the case. This single opening can be sealed with a single sealing element, eliminating the multiplication of sealing interfaces that would occur with multiple separate devices, thereby improving reliability and reducing potential failure points.
