Rotating-Plate Timepiece Gear Train for Stable Decorative Motion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing gimmick clocks lack intricate and stable operations due to limited gear ratio adjustments and reliance on gravity for decoration direction, leading to less novel and stable decorative body movements.
Innovation Solution
A timepiece design incorporating a main plate, rotating plate, gear, and transmission gear train that allows for adjustable gear ratios and stable decorative body movements through a non-rotatable connection to the gear, enabling parallel movement and opposite rotation directions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the gear is directly meshed with the tooth part to simplify the structure, then the device complexity is reduced, but the operational intricacy and stability of the decorative body deteriorates
Solution Approach 1:
The patent introduces a transmission gear train as an intermediary mechanism between the tooth part and the gear. This transmission gear train includes multiple gears that mesh with each other to transmit rotation from the tooth part to the gear, enabling complex and stable decorative body operations while maintaining structural feasibility
2Ease of manufacture
If the gear ratio is fixed to reduce component adjustments, then the ease of manufacture is improved, but the operational novelty and intricacy deteriorates
Solution Approach 1:
The patent employs a transmission gear train with multiple gears that can be adjusted to achieve different gear ratios. This dynamic configuration allows the rotational speed and direction of the gear to be varied, creating diverse and novel operational patterns for the decorative body while remaining manufacturable
3Reliability
If the decorative body is connected to the gear via transmission gear train to achieve stable operation, then the operational stability is improved, but the device complexity increases
Solution Approach 1:
The patent integrates the transmission gear train within the rotating plate structure, where multiple gears are arranged in a compact configuration. The transmission mechanism merges the rotation transmission function with the structural support of the rotating plate, achieving stable decorative body operation while controlling overall device complexity
