Solution Overview

Problem

Existing timepieces lack innovative mechanisms to dynamically change the hour circle aesthetic, failing to provide a captivating and surprising visual experience.

Innovation Solution

A timepiece design featuring rockers with decorative stones or symbols that rotate based on the position of an oscillating mass, changing the visible face of the hour ring as the timepiece is tilted, allowing for creative and dynamic decoration.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a movable hour circle mechanism is implemented, then the aesthetic effect and visual interest of the dial is improved, but the device complexity increases

Engineering Contradiction:
Improveaesthetic variation capabilityVSAvoidmechanism complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The hour circle is transformed from a static element to a dynamic one that can rotate and change orientation. The rockers (7, 8) enable the hour circle to tilt and present different decorative faces, creating visual variety without requiring multiple complete hour circles. This dynamic transformation resolves the contradiction by achieving aesthetic versatility through controlled movement rather than complex multi-component systems.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The hour circle is divided into multiple rockers (7, 8), each representing a segment of the hour circle with its own decorative face. Each rocker can independently rotate to display different hour markers or decorative elements. This segmentation allows the system to achieve multiple aesthetic states using simpler individual components rather than one complex monolithic structure.

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If multiple decorative faces are added to the rockers, then the visual interest and customization options are improved, but the manufacturing complexity increases

Engineering Contradiction:
Improvedecoration varietyVSAvoidmanufacturing simplicity
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

Multiple decorative functions are merged into single rocker components. Each rocker integrates structural elements (axis, pins, rollers) with decorative elements (stones, symbols, hour markers) in one unified piece. This merging reduces the total number of separate components that would need to be manufactured and assembled, while still providing multiple decorative faces that can be displayed through the rockers' movement.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The rockers are designed as multi-functional elements that simultaneously serve structural support, mechanical movement (through axes and pins), and decorative display purposes. Each rocker can present different decorative faces depending on its orientation, making a single component perform multiple aesthetic functions rather than requiring separate decorative elements for each face.

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

3Ease of operation

If the hour circle changes dynamically, then user engagement and visual surprise are improved, but the mechanism reliability may deteriorate

Engineering Contradiction:
Improveuser engagementVSAvoidmechanism stability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The oscillating mass (14) that provides the watch's timekeeping function also serves to drive the rocker movement through gravitational interaction. As the mass oscillates, it naturally activates the rockers to change the hour circle display without requiring a separate power source or complex control mechanism. This self-service approach maintains reliability by using the existing timekeeping motion to drive the aesthetic variation.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The hour circle changes display in periodic intervals synchronized with the oscillation cycle of the timekeeping mass. The rockers rotate at regular intervals determined by the oscillation period, creating predictable and reliable aesthetic variations rather than random or continuous movement. This periodic action ensures the mechanism remains stable and reliable while still providing dynamic visual interest.

Inventive Principle:
Principle #19Periodic action

AI summary

Timepiece with an hour circle formed by a module placed around the movement. The module cover comprises openings at the position of each hour. Inside the module are rockers with decorations in two particular positions. An oscillating mass moves when the inclination of the plane of the timepiece changes and moves the rockers from one position to the other.
