Eyebolt Holder With Elastic Blade For Timepiece Stud Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for adjusting the position of a stud relative to an eyebolt holder in timepiece balance-spring regulating members are cumbersome, especially when dealing with brittle materials, as they require precise perpendicularity and are prone to distortion due to screw immobilization, and are difficult to adjust due to small dimensions and restricted access.
Innovation Solution
A stud and stud holder assembly featuring a flexible blade that can occupy two stable positions, allowing for easy adjustment and immobilization of the eyebolt without a screw, using a hooking structure to release the eyebolt for positioning and re-immobilize it securely, enabling both longitudinal and rotational adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a screw is used to immobilize the eyebolt in its housing, then the eyebolt can be securely fixed, but the orientation of the eyebolt may be distorted
Solution Approach 1:
The invention extracts the harmful element (the screw) from the system by replacing the screw-based fixation with a friction-based retention mechanism using an elastic blade. This eliminates the source of distortion while maintaining secure fixation of the eyebolt in the housing.
Solution Approach 2:
The invention replaces the mechanical screw-based clamping system with an elastic blade retention system that uses friction and elastic deformation. The elastic blade engages with a retention groove on the eyebolt, providing secure fixation without the distorting pressure of a screw.
2Ease of operation
If traditional adjustment methods are used with small dimensions and restricted access, then the stud can be adjusted, but the operation becomes tricky and time-consuming
Solution Approach 1:
The invention makes the retention system dynamic by allowing the elastic blade to be easily deflected to release or engage the eyebolt. The hooking structure on the elastic blade can be actuated to temporarily disengage from the eyebolt, enabling quick adjustment without time-consuming operations.
Solution Approach 2:
The elastic blade acts as an intermediary mechanism between the adjustment tool and the eyebolt. The hooking structure on the blade provides a convenient engagement point for tools, facilitating easy manipulation and adjustment of the eyebolt position even in restricted spaces.
3Reliability
If the elastic blade is permanently in contact with the stud, then the stud is retained, but the adjustment becomes complex
Solution Approach 1:
The invention implements periodic action by allowing the elastic blade to alternately engage and disengage from the eyebolt. The blade can be deflected to release the eyebolt for adjustment, then returned to its engaged position to secure it, creating a simple repeatable cycle rather than a complex continuous mechanism.
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
Facilitates precise and easy adjustment of the stud's position relative to the eyebolt holder, reducing the risk of distortion and improving the perpendicularity of the spiral spring, even with brittle materials, thus enhancing the chronometric accuracy and ease of assembly.
Implementation Method 1
a groove-shaped housing arranged to receive longitudinally and position the stud, the housing being at least partially closed laterally by an elastic blade mounted on the eyebolt holder, the blade being arranged to clamp and immobilize the eyebolt against the back of the groove by elastic pressure

AI summary
The eye bolt holder has a groove-shaped housing arranged to longitudinally receive and position the eye bolt (203). The housing is at least partially closed laterally by an elastic blade (215) which is arranged to pull the eye bolt (203) against the bottom of the groove so as to immobilize it when the eye bolt (203) is inserted into the housing between the elastic blade (215) and the bottom of the groove.
