Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sympathetic clocks and watches face issues with unnecessary strain on time-setting mechanisms, wear on automatic barrels due to constant winding, and inaccurate time settings if the watch is not placed on the clock at the right time, leading to premature wear and loss of time settings.
Innovation Solution
A sympathetic clock assembly with a pendulum and watch that includes a connecting mechanism with two separate transmission lines for function selection and energy transfer, allowing for on-demand time setting, precise adjustment, and continuous winding, even when the watch is not constantly placed on the clock.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the watch is continually placed on the clock, then the time setting function is performed periodically, but this puts unnecessary strain on the time-setting mechanism
Solution Approach 1:
The system dynamically adjusts its behavior based on whether the watch is present on the clock. When the watch is removed, the time-setting mechanism is deactivated, preventing unnecessary strain. When the watch is present, the mechanism activates only when needed, creating a dynamic response that balances reliability with reduced mechanical stress.
Solution Approach 2:
The clock automatically detects when the watch is placed on it and activates the time-setting function without requiring manual intervention. The system serves itself by monitoring the watch's presence and automatically initiating the appropriate functions, reducing the need for user interaction and minimizing mechanism strain.
2Productivity
If the winding is constant and rapid, then the automatic barrel is wound quickly, but this causes significant wear on the automatic barrel
Solution Approach 1:
Instead of continuous rapid winding, the system employs periodic winding actions triggered by specific events (watch placement or removal). The barrel is wound at controlled intervals rather than continuously, maintaining productivity while significantly reducing wear on the automatic barrel mechanism.
Solution Approach 2:
The system changes the winding parameters based on conditions. When the watch is placed on the clock, rapid winding is activated to ensure full winding within a reasonable time. When the watch is removed, winding stops or reduces to minimal periodic actions, preventing excessive wear while maintaining barrel charge when needed.
3Ease of operation
If the watch is stopped when placed on the clock, then the time is not set, but this requires waiting for the next change to the set time for uncertain time setting
Solution Approach 1:
The system performs preliminary actions by automatically detecting watch placement and activating the time-setting function immediately, before the user needs to check the time. This eliminates the need to wait for the next scheduled time change and ensures the time is set as soon as possible, reducing waiting time and improving ease of operation.
4Duration of action of moving object
If the winding is planned to be constant at a fast speed, then the barrel reaches full winding quickly, but this stresses the sliding flange function of the barrel and causes premature wear
Solution Approach 1:
The system uses periodic rather than continuous fast winding. The barrel is wound at high speed only during specific periods when the watch is placed on the clock and needs charging. Between these periods, winding is minimized or stopped, reducing stress on the sliding flange and preventing premature wear while still achieving full winding when needed.
Solution Approach 2:
The system maintains continuity of useful action by ensuring the barrel is wound sufficiently before the watch is removed, so the watch remains operational. However, this continuous useful action is achieved through strategic periodic winding rather than continuous fast winding, balancing the need for operational readiness with the need to protect the barrel mechanism.
