Watch Case Mechanism for Automatic Latch Actuation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing watch cases do not allow for automatic activation of a lock function, such as a chime mechanism, when the watch is positioned in its case, limiting the functionality of high-end repeater watches.
Innovation Solution
A watch case with a mechanical locking actuation device that automatically activates the lock function, controlled by an internal clock and programming means, allowing for automatic actuation of the lock when the watch is in its housing, and includes an automatic winding mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If the watch is placed in its case, then the watch is protected and stored, but the lock function cannot be automatically activated
Solution Approach 1:
The system enables self-service by allowing the watch to automatically activate its lock function when placed in the case, without requiring manual intervention from the user. The mechanical actuation device and control means work together to detect the watch's presence in the case and automatically trigger the lock mechanism, making the system serve itself rather than requiring continuous user operation.
Solution Approach 2:
The control means and mechanical actuation device are pre-configured to automatically activate the lock function when the watch is placed in the case. The system performs the necessary actions in advance based on the watch's presence, eliminating the need for the user to manually operate the lock function each time the watch is stored in its case.
2Extent of automation
If a mechanical actuation device is added to the case, then automatic lock activation is enabled, but the device complexity increases
Solution Approach 1:
The patent introduces a mechanical actuation device as an intermediary component between the case and the watch's lock mechanism. This intermediary includes a lever mounted in the case lid that carries a pin, which mechanically connects to the lock when the case is closed. This intermediary mechanism enables automatic activation while maintaining a relatively simple structure that integrates seamlessly with the existing case and watch design.
3Ease of operation
If the lock function is activated manually, then the user can control the function, but the convenience of automatic activation is lost
Solution Approach 1:
The system achieves multi-functionality by providing both automatic activation through the mechanical actuation device and manual control through the traditional lock mechanism. The lock can be activated automatically when the watch is placed in the case, or manually by the user through the existing lock mechanism, making the system adaptable to different user needs and preferences.
