Electronic Timepiece Lubricating Apparatus Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic timepieces with high rotation rotors face difficulties in processing and component complexity due to integrated stator guides in lubricating apparatuses, leading to increased component types and alignment precision issues.
Innovation Solution
The electronic timepiece employs a lubricating apparatus and stator guide with cylindrical shapes, where the lubricating apparatus is fitted into a constant-diameter opening in the bottom plate, followed by the stator guide with a larger outer diameter, allowing for precise alignment and simplifying processing and component types.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the stator guide is integrated in the lubricating apparatus, then the staff center of the rotor and the center of the opening of the stator can be aligned with high precision, but the processing for the lubricating apparatus becomes difficult
Solution Approach 1:
The patent divides the integrated structure into separate components: the lubricating apparatus and the stator guide are made as independent parts. The lubricating apparatus has a simple cylindrical shape that is easy to process, while the stator guide is a separate component with its own positioning features. This segmentation maintains alignment precision through the positioning hole and guide structure while significantly simplifying the processing of each individual component.
2Manufacturing precision
If the lubricating apparatus has a guide-shape fit into the opening of the stator, then the alignment is maintained, but the number of types of bearing components increases
Solution Approach 1:
The patent makes the lubricating apparatus serve multiple functions: it provides lubrication, supports the rotor staff, and works in conjunction with the positioning hole to maintain alignment. By making the lubricating apparatus multi-functional rather than creating a separate dedicated guide component, the design reduces the number of component types while maintaining alignment precision through the collaborative positioning system.
3Reliability
If the lubricating apparatus has a complicated structure to support multiple members, then the lubrication function is enhanced, but the processing becomes more difficult
Solution Approach 1:
The patent segments the lubrication support function from the positioning function. The lubricating apparatus has a simple cylindrical shape that is easy to process, while the positioning function is achieved through the collaboration with the stator guide and positioning hole. This segmentation maintains reliable lubrication support while significantly reducing processing difficulty.

AI summary
Lubricating apparatuses (10, 20, 30, 40) that support the axes of a stator guide (70) and a rotor (50) fit into an opening of a stator (60) are separate components and by fitting the stator guide (70) and lubricating apparatuses (10, 20, 30, 40) into the cylindrically shaped opening of a constant diameter disposed in a bottom plate (80), a bearing can be configured that aligns the central axis of the opening of the stator (60) and the rotational axis of the rotor (50) with high precision. Additionally, the structure of the lubricating apparatus (10, 20, 30, 40) is simplified and configures an electronic timepiece that can use the bearing-less stator (60).
