Watch Corrector Segmentation for Strap Actuation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional watch corrector arrangements in the bracelet attachment links face issues with manufacturing tolerances and aesthetic compatibility, leading to potential deterioration or rupture due to side movements and the need for aesthetic compromises that may weaken the correctors.
Innovation Solution
A watch design featuring a corrector system with a first pusher mounted in the watch box and a second pusher in the bracelet fastener, where the second pusher is not attached to the first, allowing for actuation to simplify the mechanism and reduce stress on the correctors, eliminating the need for aesthetic compromises and lateral movements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the corrector is mounted as a single piece extending from the box wall into the attachment link, then the mechanism inside the box is simplified, but manufacturing tolerances require clearance gaps that lead to side movements and risk deterioration or rupture of the corrector
Solution Approach 1:
The corrector is divided into two separate pushers: a first pusher mounted in the box wall and a second pusher mounted in the attachment link. These two pushers are not attached to each other, allowing independent positioning and eliminating the need for clearance gaps that cause side movements. This segmentation resolves the contradiction by maintaining simplicity while improving reliability.
2Ease of manufacture
If clearance gaps are provided between the corrector and attachment link to accommodate manufacturing tolerances, then assembly is facilitated, but aesthetic criteria of Haute Horlogerie are compromised
Solution Approach 1:
By separating the corrector into two independent pushers mounted in different locations (box wall and attachment link), the design eliminates the need for visible clearance gaps between components. Each pusher can be precisely positioned in its own mounting location, achieving both easy assembly and high aesthetic standards.
3Volume of moving object
If the corrector is made with small diameter to fit in the attachment link, then the mechanism remains compact, but the corrector becomes particularly fragile and prone to deterioration
Solution Approach 1:
The corrector function is split between two pushers of appropriate sizes for their respective locations. The first pusher in the box wall can have a larger, more robust diameter, while the second pusher in the attachment link is sized appropriately for that location. This eliminates the constraint of using a uniformly small diameter throughout, thereby improving strength without increasing overall volume.

AI summary
The watch (1) according to the invention comprises a case (2) containing a timekeeping device (3), a strap (4) attached to the case (2), and at least one corrector (18) for correcting the value of at least one quantity displayed by the timekeeping device (3). The corrector (18) extends into the wall of the case (2) and into an attachment link (5) of the strap (4) so that it can be operated by the user from the attachment link (5). This watch is distinguished in that the corrector (18) comprises a first pusher (19) mounted in the wall of the case (2) and a second pusher (20) mounted in the attachment link (5) and not attached to the first pusher (19), the second pusher (20) pushing the first pusher (19) when it is operated.
