Rotary Timepiece Correction Mechanism for Fewer Case Openings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The proliferation of corrective devices on the case of timepieces, particularly those with multiple complications, leads to aesthetic and sealing issues due to the multiplication of openings in the watch case, compromising water resistance and elegance.
Innovation Solution
A multifunctional correction device that allows the selection and activation of at least two different functions using a single opening in the watch case, integrating a control element that interacts with multiple function correctors through angular positions, minimizing the need for additional openings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple corrective devices are added 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 aesthetic degradation and sealing problems
Solution Approach 1:
A single multifunctional correction device is designed to control multiple complications through different angular positions of its control element. The control element can be positioned at various angles (e.g., 0°, 45°, 90°, 135°) to selectively engage different function correctors, allowing one device to perform the work of multiple separate devices while maintaining the ability to control each complication individually.
Solution Approach 2:
Multiple function correctors that would traditionally require separate control devices are merged into a single integrated correction device. The control element of this unified device can interact with multiple function correctors simultaneously or sequentially, combining what would have been separate correction mechanisms into one cohesive unit that reduces the number of case openings needed.
2Adaptability or versatility
If multiple corrective devices are added to control multiple complications, then the functionality and versatility of the timepiece is improved, but the aesthetic appearance deteriorates due to multiple openings
Solution Approach 1:
The multifunctional correction device serves multiple complications through a single control element with multiple angular positions, eliminating the need for multiple separate control devices. This universal approach maintains the case's sleek, unbroken appearance while providing comprehensive control over date, time zone, and other complications.
3Adaptability or versatility
If multiple corrective devices are added to control multiple complications, then the functionality and versatility of the timepiece is improved, but water resistance is compromised due to increased openings
Solution Approach 1:
By consolidating control of multiple complications into a single multifunctional correction device, the number of case openings is minimized. Each opening represents a potential vulnerability to water penetration, so reducing the count from multiple separate openings to one or fewer significantly enhances water resistance while maintaining full functionality for controlling date, time zone, and other complications.
