Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mechanical watches with mobile organs, such as display devices and regulating mechanisms, have fixed inclinations that cannot be adjusted during use, affecting aesthetic observation and functionality.
Innovation Solution
A watch movement with a tiltable member that allows adjustable inclination relative to a plate, using variable adjustment means with spherical and straight-cut teeth for optimal meshing and actuation, enabling the member to be inclined within a range of 0° to 90°.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If the regulating organ is inclined on the plate for aesthetic reasons and better observation, then the aesthetic effect and visibility are improved, but the actuation meshing between the return and the member becomes difficult to maintain across all orientations
Solution Approach 1:
The return is given a concave spherical shape with substantially spherical teeth on its peripheral face, allowing it to mesh with the activation teeth of the inclined member regardless of the member's orientation relative to the plate. This spherical geometry enables the return to maintain proper engagement while the member is inclined at various angles, resolving the contradiction between aesthetic inclination and reliable actuation.
Solution Approach 2:
The invention changes the geometric parameters of the return from a conventional flat or cylindrical shape to a concave spherical shape with spherical teeth. This parameter change allows the return to adapt to different orientations of the inclined member, maintaining meshing capability while permitting the member to be inclined for aesthetic and observational purposes.
2Ease of manufacture
If the inclination of the regulating organ is fixed during construction and assembly, then the manufacturing process is simple, but the inclination cannot be changed during use to optimize observation and functionality
Solution Approach 1:
The invention makes the inclination of the regulating organ adjustable rather than fixed. The member can be tilted at an adjustable angle relative to the plate, allowing users to optimize the orientation for observation and functionality. The spherical return mechanism enables this dynamic adjustment while maintaining proper actuation meshing throughout the range of motion.
3Ease of manufacture
If the return uses conventional straight teeth for actuation, then the manufacturing is simpler, but optimal meshing cannot be achieved for all orientations of the inclined member
Solution Approach 1:
The return is given a concave spherical shape with substantially spherical teeth on its peripheral face, allowing it to mesh with the activation teeth of the inclined member regardless of the member's orientation relative to the plate. This spherical geometry enables the return to maintain proper engagement while the member is inclined at various angles, resolving the contradiction between aesthetic inclination and reliable actuation.
Solution Approach 2:
The invention changes the geometric parameters of the return from a conventional flat or cylindrical shape to a concave spherical shape with spherical teeth. This parameter change allows the return to adapt to different orientations of the inclined member, maintaining meshing capability while permitting the member to be inclined for aesthetic and observational purposes.
