Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing timepiece winding mechanisms require separate manual or electric winding for each barrel powering independent mechanisms, lacking a unified automatic and/or manual winding solution that can benefit from the winding of one barrel to efficiently power both.
Innovation Solution
A winding mechanism with automatic and/or manual winding means that utilizes a distribution differential with epicyclic gear train to distribute winding torque unequally between two independent barrels, allowing for simultaneous winding of both barrels with preference given to the primary movement barrel over secondary mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If separate manual or electric winding is used for each barrel, then each independent mechanism can be powered, but the device complexity increases and winding operation becomes more cumbersome
Solution Approach 1:
The patent combines multiple winding operations into a single unified winding mechanism. The common winding means includes a single mainspring barrel that can simultaneously or selectively wind both the first and second barrels through a shared winding axis and gear train, eliminating the need for separate winding operations for each barrel.
Solution Approach 2:
The winding mechanism is designed with multi-functionality to handle different winding scenarios. The common winding means can operate in multiple modes: winding both barrels simultaneously, winding only the first barrel, or winding only the second barrel, providing universal applicability for various power distribution needs.
2Ease of operation
If a single automatic winding mechanism winds both barrels simultaneously, then winding operation is simplified, but the ability to favor one barrel over the other is reduced
Solution Approach 1:
The patent introduces dynamic control capabilities to the winding mechanism. The selective engagement means allow the system to dynamically adjust which barrel receives winding torque based on operational needs. The differential mechanism enables dynamic distribution of winding energy, allowing preference to be given to either the first or second barrel as required.
Solution Approach 2:
The patent employs intermediary mechanisms between the common winding means and the individual barrels. The differential mechanism and selective engagement means act as intermediaries that can redirect or prioritize winding torque to specific barrels, providing adaptability while maintaining the simplified single-winding-operation interface.
3Use of energy by moving object
If energy is distributed equally between two barrels, then both mechanisms are powered, but energy efficiency is optimized when distribution can be adjusted based on mechanism needs
Solution Approach 1:
The patent incorporates feedback mechanisms that monitor the power needs of different mechanisms. The selective engagement means respond to operational conditions and automatically adjust torque distribution accordingly, ensuring that energy is directed to the mechanism that requires it most at any given moment, thereby optimizing energy efficiency.
Solution Approach 2:
The differential mechanism allows for parameter changes in torque distribution. By adjusting the mechanical advantage ratios and engagement characteristics of the differential gears, the system can vary the amount of winding torque allocated to each barrel, optimizing energy distribution efficiency based on the specific power requirements of each mechanism.
