Timepiece Rapid Correction Mechanism with Safety Flip-Flop
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing timepiece display mechanisms, such as those for annual calendars, require lengthy and error-prone corrections, often leading to desynchronization and potential malfunctions during rapid adjustments, especially when correcting dates or months, due to the complexity of flip-flop mechanisms and lack of synchronization verification.
Innovation Solution
A rapid correction mechanism incorporating a return mobile and safety flip-flop system ensures synchronization by using a safety flip-flop that interferes with the return mobile to resynchronize it when desynchronization occurs, preventing system malfunctions and ensuring correct operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If a rapid correction mechanism is implemented for date/month display, then the correction time is reduced, but the risk of desynchronization and malfunctions increases
Solution Approach 1:
The patent implements a feedback mechanism where the safety flip-flop continuously monitors the synchronization state of the return mobile and automatically triggers correction actions when desynchronization is detected, ensuring the system self-corrects without user intervention
Solution Approach 2:
The safety flip-flop autonomously detects desynchronization conditions and initiates resynchronization procedures without requiring user verification or manual intervention, making the system self-service capable
2Ease of operation
If manual correction by date is performed repeatedly to correct month display, then the month display can be corrected, but the manipulation becomes long and tedious
Solution Approach 1:
The patent prepares the rapid correction mechanism in advance with pre-configured date/month correspondence, so when month correction is needed, the system can immediately execute the correct transformation without requiring sequential date adjustments
Solution Approach 2:
The safety flip-flop acts as an intermediary that coordinates between the date correction mechanism and month display, ensuring that rapid date corrections automatically and accurately update the month display without requiring separate manual intervention
3Device complexity
If the user has no means of verifying synchronization, then the mechanism is simpler, but desynchronization cannot be detected
Solution Approach 1:
The safety flip-flop provides automatic feedback on synchronization status by mechanically detecting the positional relationship between the return mobile and display elements, eliminating the need for complex user verification procedures

AI summary
Display mechanism (500) comprising a rapid correction mechanism (200) for the position of a display movement (3), a setting wheel movement (6) ensuring synchronization having automatic drive means, and, inserted between said setting wheel movement (6) and said display movement (3), a security lever (400) driven by said display movement (3) during the periodic driving thereof, along a path interfering with the volumetric space of said setting wheel movement (6), in such a way that: - when said setting wheel movement (6) is correctly synchronized, the path of said lever (400) does not interfere with said setting wheel movement (6); - when said setting wheel movement (6) is not correctly synchronized, the trajectory thereof interferes with said setting wheel movement (6), which said security lever (400) then drives in the direction opposite to the single direction of its normal operation, to re-synchronize said setting wheel movement (6).
