Layered Watch Glass Setting for Crack-Resistant Gem Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing watch glasses with decorative elements lack a secure and stable attachment method, leading to potential microcracks and increased risk of splintering, especially with large decorative elements, and often fail to provide a watertight seal.
Innovation Solution
A watch glass structure comprising two glasses connected via a connecting intermediate layer, with a decorative element inserted in a recess, where the space is filled with connecting material to distribute impact energy and prevent direct contact between the setting and the glasses, ensuring a stable and watertight connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a decorative element is directly attached to the watch glass, then the attachment is simple, but the risk of microcracks and splintering increases
Solution Approach 1:
A setting piece made of elastic material is introduced as an intermediary between the decorative element and the watch glass. This setting piece absorbs impact energy and prevents direct transmission of forces to the glass, thereby eliminating the risk of microcracks and splintering while maintaining secure attachment.
2Device complexity
If a single glass is used, then the structure is simple, but the stability and impact distribution are insufficient
Solution Approach 1:
The watch glass is divided into two separate glass pieces that are connected to each other. This segmentation allows impact forces to be distributed across both glass pieces rather than concentrating stress on a single glass, thereby enhancing overall stability and resistance to microcracks.
3Strength
If the setting directly contacts the glass, then the connection is strong, but the risk of splintering at the recess position increases
Solution Approach 1:
The elastic setting piece serves as a mediator between the decorative element and the glass. It provides sufficient connection strength while preventing direct contact between hard surfaces, thereby eliminating the risk of splintering at the recess position where the setting contacts the glass.
4Device complexity
If no connecting material is used in the recess space, then the structure is simpler, but the setting connection is insufficient
Solution Approach 1:
The connecting material is integrated into the recess space of the setting piece, merging the connection function with the structural design. This ensures reliable attachment of the setting to the glass while maintaining a compact and simple overall structure.
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 solution provides a stable, secure, and watertight watch glass that prevents microcrack transfer and reduces splintering risks, while allowing for large decorative elements without compromising the integrity of the glass.
Implementation Method 1
due to the contacting of the glasses with the connecting intermediate layer, which has a greater elasticity in comparison with the glasses, in the case of a potential impact of the decorative element and/or of the setting, the impact energy can be distributed to both glasses via the connecting intermediate layer and absorbed by those
Implementation Method 2
The connecting intermediate layer and in particular the connecting material thereof in the space of the watch glass recess between the first glass, the second glass and the setting further enables a fixed connection of the setting
Implementation Method 3
the present invention offers the advantage of a watertight watch glass, since due to adhesion and/or cross-linking effects the setting abuts on the glasses and the glasses abut on one another in a watertight manner
Implementation Method 4
In addition, potential surface deviations of the glasses can be compensated by the connecting intermediate layer, what results to a very stable connection of the glasses

AI summary
A watch glass includes a first glass, a second glass and a decorative element. The second glass is connected to the first glass via a connecting intermediate layer. The decorative element is inserted in a setting, which is arranged in a watch glass recess. The watch glass recess is formed by a first recess in the first glass and a second recess in the second glass. Here, a space of the watch glass recess is defined by the first glass, the second glass and the setting. The space is filled with connecting material of the connecting intermediate layer, so that the setting is connected via the connecting material to the first class and the second glass.
