Solution Overview

Problem

Existing watch display mechanisms face challenges in maintaining readability as the number of time values to display increases, particularly with concentric discs, leading to reduced readability and requiring convergent reading efforts, which limits practical utility.

Innovation Solution

A clockwork display mechanism that uses a sliding carriage driven by a clockwork movement or drive mechanism, traversing a complex trajectory defined by complementary guide means, allowing the display to move in different directions and change tracks seamlessly, enabling a customizable and highly readable display along a figure-eight trajectory.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If concentric disk displays are used to show multiple time values, then the display capacity increases, but the readability decreases

Engineering Contradiction:
Improvenumber of time values displayedVSAvoidreadability
Core Design Contradiction:
Quantity of substanceVSMeasurement precision

Solution Approach 1:

The patent transitions from two-dimensional concentric disk displays to a three-dimensional spatial trajectory system. The display element travels along a defined path in three-dimensional space, allowing multiple time values to be displayed sequentially at different positions and orientations, thereby maintaining readability while increasing display capacity.

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

Solution Approach 2:

The display mechanism employs dynamic movement of the display element along a predetermined trajectory. Instead of static concentric disks, a single display element moves through space to present multiple time values sequentially, with the movement controlled by guide means that enable smooth transitions and directional changes along the trajectory.

Inventive Principle:
Principle #15Dynamics

2Quantity of substance

If multiple indicators are displayed side by side, then the display capacity increases, but the intellectual effort required for reading increases

Engineering Contradiction:
Improvenumber of time values displayedVSAvoidreading effort
Core Design Contradiction:
Quantity of substanceVSEase of operation

Solution Approach 1:

The display trajectory is segmented into multiple distinct zones, each dedicated to displaying a specific time value. The guide means is correspondingly segmented into multiple tracks that guide the display element through each zone sequentially. This segmentation allows the reader to focus on one time value at a time as the display element passes through each zone, reducing the intellectual effort required to process multiple simultaneous indicators.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The display element periodically visits each display zone along the trajectory, allowing each time value to be presented in sequence rather than simultaneously. This periodic presentation at optimized positions and orientations reduces reading effort while maintaining the capacity to display multiple time values.

Inventive Principle:
Principle #19Periodic action

3Measurement precision

If the display follows a complex trajectory with direction changes, then the customization and readability improve, but the mechanism complexity increases

Engineering Contradiction:
ImprovereadabilityVSAvoidmechanism complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

Multiple guiding functions are merged into a single integrated guide means structure. The guide means combines multiple tracks and directional control elements into one unified component that simultaneously provides lateral guidance, longitudinal positioning, and directional changes. This merging reduces the number of separate components needed while achieving the complex trajectory required for optimized readability.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The guide means is designed as a multi-functional component that performs multiple guiding tasks along a single trajectory. It provides lateral guidance to keep the display element on course, longitudinal positioning to control the sequence of display zones, and directional changes to optimize the presentation of each time value. This universal guide means reduces overall mechanism complexity while achieving complex display patterns.

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