Annular Module Rotary Indicator for Peripheral Time Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional timepiece displays are aesthetically conventional and lack innovative methods for indicating time information.
Innovation Solution
A mechanical movement featuring an annular module with a movable ring and rotary indicator, driven by a rolling means, displays time information peripherally, allowing for original and unconventional time indication methods, suitable for both mechanical and quartz watches.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional hands or rings are used to display time indications, then the timepiece maintains traditional aesthetic codes, but the display method lacks innovation and originality
Solution Approach 1:
The patent employs a dynamic display mechanism where a hand rotates around the dial perimeter rather than following conventional radial motion from the center. This dynamic movement allows the time indication to traverse the entire circumference of the dial, creating an original and versatile display method that breaks from traditional aesthetic conventions while maintaining mechanical simplicity
Solution Approach 2:
The invention transitions from the conventional two-dimensional radial display (hands extending from center to edge) to a one-dimensional peripheral traversal (hand moving along the circumference). This dimensional change in the display trajectory enables novel time indication methods while keeping the mechanical structure relatively simple
2Adaptability or versatility
If a peripheral display module is added to the timepiece, then original time indication is achieved, but the device complexity increases
Solution Approach 1:
The patent designs a universal annular module that can be integrated into both mechanical and quartz watch movements. The module uses a standardized crown mechanism that can be driven by either mechanical mainspring energy or quartz motor actuation, allowing the same display structure to serve multiple function types without increasing complexity
Solution Approach 2:
The invention introduces a crown as an intermediary element that mediates between the drive train and the display hand. The crown acts as a universal interface that can receive rotational input from different power sources (mechanical or electrical) and convert it into the required peripheral hand movement, simplifying the overall system architecture
3Loss of information
If the rotary indicator displays time information continuously during rotation, then complete time information is provided, but the manufacturing precision requirements increase
Solution Approach 1:
The patent applies local quality by concentrating the time information display at specific locations along the hand's trajectory rather than requiring uniform precision throughout. The hand is designed with specific markings or luminous elements at key positions (such as 12, 3, 6, 9 o'clock positions) that provide reference points for accurate time reading, while other portions of the hand can have simpler construction requirements
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables unique and original time indication on the periphery of the dial, maintaining accessibility for additional displays or complications while providing a power reserve of up to three days.

AI summary
A movement for a timepiece comprises a plate (1) and an annular module (2) circumferentially surrounding the plate (1). The module (2) comprises a mobile ring (2") mounted so as to be made to rotate about its axis by a rolling means, the mobile ring (2") carrying a rotary indicator (3). The rotary indicator (3) is an attachment, of which a first part (3A) fixed to a crown (5) arranged on the mobile ring (2") is flat and parallel to a plane defined by the crown (5) and a second part (3B) is a protruding curved part. The second part (3B), in the shape of a tip, is oriented towards the centre of the crown (5), the crown (5) comprising a housing for receiving one end of the first part (3A) of the rotary indicator (3). The movement further comprises a drive train (4) for driving the mobile ring (2") in rotation at a speed of rotation imparted by the timepiece movement, such that, when it is driven around the periphery of the plate (1), the rotary indicator (3) displays time information indicating hours, minutes or seconds.
