Offset Contact Wheel Structure for Horology Lubrication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Horology movements face precision issues due to friction between components, which leads to wear and inefficient lubrication, as conventional lubricants often disperse within the movement.
Innovation Solution
A horology component, such as a wheel, with distinct contact surfaces offset relative to each other to direct lubricant from one contact zone to another, ensuring continuous lubrication without dispersion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a liquid lubricant is applied to reduce friction between horology components, then friction and wear are reduced, but the lubricant disperses inside the horology movement and is lost from the contact zone
Solution Approach 1:
The contact surface is divided into multiple distinct contact zones that are offset from each other. Each contact zone receives lubricant independently, creating segmented lubrication paths that prevent lubricant dispersion while maintaining continuous lubrication across all contact surfaces
Solution Approach 2:
The invention introduces an offset dimension between contact zones on the same contact surface. By positioning contact zones at different locations (offset in radial or axial direction), the lubricant is guided along a specific path from one contact zone to another, preventing radial dispersion and maintaining lubricant retention
2Loss of substance
If conventional lubrication is used with overlapping contact zones, then lubricant is retained in the contact zone, but friction and wear increase due to insufficient lubricant redistribution
Solution Approach 1:
The offset configuration of contact zones is designed in advance to guide lubricant flow from one contact zone to the next. This preliminary structural arrangement ensures that lubricant is automatically redistributed to subsequent contact zones before they engage, maintaining continuous effective lubrication without relying on lubricant retention in a single overlapping zone
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
This configuration maintains effective lubrication between components, reducing wear and enhancing the precision and longevity of horology movements by ensuring consistent lubrication across non-overlapping contact zones.
Implementation Method 1
horology components in contact are subjected to friction, which leads to wear in the parts
Implementation Method 2
In order to reduce this friction, it is customary to utilize a liquid lubricant on the friction zones of horology components

AI summary
Horology component intended to cooperate via a lubricated contact with at least one second horology component within a horology movement, said horology component comprising at least two distinct contact surfaces intended to cooperate with the same second horology component, characterized in that said two contact surfaces are offset with respect to one another, such that a first contact surface is adapted to displace a lubricant present on the second horology component towards a surface with which the second contact surface will subsequently come into contact.
