Prismatic Display Device with Synchronized Wheel Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional watchmaking display devices are unable to sequentially indicate multiple time-related information, such as hours, minutes, and date, using a single display mechanism, which limits their functionality and user experience.
Innovation Solution
A timepiece with a synchronized wheel system and lever mechanism that allows a single display device to show different indications by selectively engaging cams with varying rotation speeds and shapes, using a selection wheel to activate levers associated with each indication, enabling sequential display of information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple independent retrograde displays are used to show different indications, then each indication can be displayed simultaneously, but the device complexity increases
Solution Approach 1:
A single display device is designed to perform multiple functions by sequentially displaying different indications (hours, minutes, date) through one shared display mechanism controlled by the synchronization wheel and lever system, eliminating the need for multiple independent display systems
Solution Approach 2:
The display device transitions between different display modes dynamically through the rotation of the synchronization wheel, which sequentially engages different levers to switch between displaying hours, minutes, and date information on the same display structure
2Device complexity
If a single display device is used to show multiple indications sequentially, then the device complexity is reduced, but the ability to display multiple indications simultaneously is limited
Solution Approach 1:
The synchronization wheel rotates periodically to sequentially activate different levers at predetermined intervals, enabling the single display device to cycle through displaying hours, minutes, and date information in a repeating sequence, effectively providing multiple indications over time
3Adaptability or versatility
If multiple cams with different rotation speeds are used, then different indication speeds can be achieved, but the mechanism complexity increases
Solution Approach 1:
Multiple cams with different rotation characteristics (hour cam, minute cam, date cam) are merged into a single synchronization wheel structure, allowing different indications to be driven at appropriate speeds through one integrated mechanism rather than separate independent mechanisms
