Solution Overview

Problem

Existing universal watches are complex and bulky due to their mechanisms for displaying multiple time zones, making it difficult to clearly read the time in different zones, especially when changes occur.

Innovation Solution

A universal watch design that groups opposite time zones in the same display zone, using a secondary display with geographical landmarks and superimposed day/night indicators, driven by a movement that synchronizes with the main time display, allowing each screen to occupy different positions based on torque and friction mechanisms, reducing the complexity and size.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a classic solution with a 24-hour hour circle and rotating ring is used to display multiple time zones, then the display of universal time is achieved, but the device complexity and thickness increase substantially

Engineering Contradiction:
Improvedisplay of multiple time zonesVSAvoidmechanism complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent combines opposite time zones (e.g., 12h and 0h, 1h and 23h) into the same display zone on the dial. Each zone displays two time references simultaneously, reducing the number of separate display elements needed and simplifying the overall mechanism while maintaining the ability to show multiple time zones.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent introduces a vertical dimension by superimposing day/night indicators above each time reference on the dial. This allows additional information (day/night status) to be displayed without adding horizontal complexity or requiring separate rotating rings, effectively using the vertical space above existing elements.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Adaptability or versatility

If a rotating ring mechanism with 24-hour display is used, then universal time display is achieved, but the thickness of the movement increases

Engineering Contradiction:
Improveuniversal time display capabilityVSAvoidmovement thickness
Core Design Contradiction:
Adaptability or versatilityVSLength of stationary object

Solution Approach 1:

The patent merges opposite time zones into shared display zones, eliminating the need for a separate rotating ring mechanism that would require substantial thickness. The time zone indication is integrated directly into the dial structure, reducing the vertical space required for the mechanism.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent extracts the day/night indication function from a separate mechanical mechanism and integrates it as a visual overlay on the existing time display. This removes the need for additional thick rotating components while maintaining the universal time display capability.

Inventive Principle:
Principle #2Taking out (Extraction)

3Loss of information

If multiple separate display mechanisms are used for different time zones, then comprehensive time information is provided, but the mechanism becomes complex and bulky

Engineering Contradiction:
Improvecompleteness of time informationVSAvoidmechanism complexity
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The patent combines multiple time references and their corresponding day/night indicators into shared dial zones. Each zone displays two time references (opposite time zones) with their respective day/night status, consolidating what would otherwise require separate display mechanisms into a single integrated dial.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent creates multi-functional display zones that simultaneously show multiple time references and their day/night status. Each zone on the dial serves multiple purposes: displaying local time, indicating day/night period, and providing reference for opposite time zones, thereby reducing the need for dedicated separate mechanisms.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

A universal watch (1) comprising: - a drive movement (10) for a main display means (2) cooperating with a secondary display means (3), - adjustment means (4) for said main display means (2) for setting the time at a specific location, - a secondary display means (5) movable relative to said secondary display means (3), and comprising geographical markers (6) for different time zones. This movement (10) drives, synchronously with the main display means (2): - said secondary display means (5), - a structure (7) carrying a plurality of primary displays (8), each superimposed on a geographical marker (6) and, depending on the time of day, changing position under the action of a driving torque from the drive means (9) which is greater than the resisting torque imparted to it by friction means (11) connected to said structure (7).
