Oscillating Winding Mass with Embedded Decoration for Movement Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing self-winding watches with transparent backs are aesthetically hindered by the oscillating winding weight, which obstructs the view of the movement and lacks visually appealing decorative elements.
Innovation Solution
An oscillating winding mass with a decorative element integrated into the main element, comprising superimposed parts and amorphous metal, allowing the decorative element to be embedded within the mass for enhanced aesthetics and visibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If a conventional oscillating winding mass is used in a self-winding movement, then the movement can be automatically wound, but the winding mass obstructs the view of the movement through the transparent back
Solution Approach 1:
The patent applies porous or mesh-like material to the oscillating winding mass, allowing light to pass through and the movement to be observed while maintaining the functional mass of the winding weight. This resolves the contradiction by making the winding mass partially transparent rather than solid, thus preserving both automatic winding capability and visual observability through the transparent back.
2Area of stationary object
If the oscillating winding mass is made transparent or with open patterns, then the view of the movement is improved, but the aesthetic appeal and branding visibility are reduced
Solution Approach 1:
The patent combines transparent or mesh-like material with decorative elements such as logos, brand acronyms, or ornamental patterns integrated into the winding mass. This composite approach allows the movement to be observed through the transparent portions while simultaneously displaying aesthetic decorations and branding, thus resolving the contradiction between visibility and aesthetic appeal.
3Shape
If decorative elements are engraved or colored on the oscillating winding mass, then aesthetic appeal is improved, but the color deteriorates over time and visibility of the movement is still obstructed
Solution Approach 1:
Instead of using surface engraving or coloring that deteriorates, the patent incorporates decorative elements as integral parts of the porous/mesh structure of the winding mass itself. The decorations are formed within the material structure rather than applied on the surface, making them permanent and non-fading while maintaining the transparency needed for movement visibility.
4Shape
If a solid oscillating winding mass is used, then the aesthetic decoration can be applied, but it obstructs the view of the movement and reduces the overall attractiveness
Solution Approach 1:
The patent employs porous or mesh-like material for the oscillating winding mass, which inherently provides both aesthetic appeal and visibility. The porous structure itself creates an attractive visual pattern while allowing movement observation, eliminating the need for separate decoration processes and solid material construction, thus simplifying manufacturing while enhancing overall attractiveness.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The integrated decorative element enhances the aesthetic appeal of the winding mass and provides unobstructed viewing of the movement, offering a more attractive and visually appealing timepiece design.
Implementation Method 1
the main element comprising amorphous or at least partially amorphous metal, preferably in its entirety
Implementation Method 2
the decorative element comprises metallic foam
Implementation Method 3
the heavy part comprises amorphous or at least partially amorphous metal of high density, preferably in its entirety
