Waterproof Watch Bezel Structure for Pressure Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional waterproof bezels for watches have unsatisfactory compression resistance, are prone to damage, and can lead to water ingress due to gaps formed under pressure. Additionally, the adhesive mounting process for glass panels in watch protection cases is costly and can result in inaccurate fitness, affecting touch sensitivity.
Innovation Solution
The proposed solution involves a waterproof bezel design with a first and second bezel body connected along an axial direction, forming an acute angle and a deformation space. This design enhances compression resistance by allowing the bezel to deform and accumulate elasticity, preventing gaps and water ingress. The bezel is bonded to a watch screen protection panel, which is quickly clamped into a housing using a clamping groove, eliminating the need for adhesive and reducing mounting costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a conventional waterproof bezel with circular or square cross section is used, then the waterproof function is achieved, but the compression resistance is unsatisfactory and the bezel is prone to damage
Solution Approach 1:
The waterproof bezel is divided into multiple segments along its circumferential direction, allowing each segment to independently deform and absorb compression forces, thereby improving overall compression resistance and damage resistance while maintaining the waterproof seal
Solution Approach 2:
The waterproof bezel incorporates a flexible or elastic material that allows dynamic deformation under compression, enabling the structure to adapt to pressure changes without breaking, thus improving both compression resistance and damage resistance
2Reliability
If a conventional waterproof bezel is not attached to the dial, then the assembly is simple, but gaps appear easily under large pressure causing water ingress
Solution Approach 1:
The waterproof bezel is pre-attached to the dial during the assembly process, establishing a secure connection before the watch undergoes pressure tests or actual use, thereby preventing gap formation and water ingress without requiring complex additional attachment mechanisms during operation
3Manufacturing precision
If adhesive pressing is used to mount the glass panel, then the mounting process is simple, but the fitness between the glass panel and screen is inaccurate affecting touch sensitivity
Solution Approach 1:
The adhesive pressing process is replaced with a mechanical clamping system that uses precise mechanical forces to secure the glass panel to the screen, eliminating the variability of adhesive thickness and pressure, thereby achieving accurate fitness without requiring costly equipment or complex adhesive application processes
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 enhanced deformation resistance of the waterproof bezel prevents water ingress even under excessive pressure, while the clamping groove mounting method reduces costs and eliminates adhesive-related issues, ensuring accurate fitness and improved touch sensitivity.
Implementation Method 1
a deformation space is formed between a portion of the first bezel body and a portion of the second bezel body that from the acute angle; the deformation space is formed between an outward obliquely-extending portion of the second bezel body and the first bezel body

AI summary
A waterproof bezel, a light-transmissive watch panel, and a watch protection case are provided. The watch protection case includes a watch screen protection panel, a waterproof bezel, and a housing. The housing is provided with a clamping groove, such that the watch screen protection panel is quickly mounted to the housing. The waterproof bezel includes a first bezel body and a second bezel body that are connected along an axial direction of the waterproof bezel. The first bezel body can bond the watch screen protection panel. The second bezel body can abut against a watch screen. An acute angle is formed between the second bezel body and the first bezel body. A deformation space is formed between a portion of the first bezel body and a portion of the second bezel body that form the acute angle.
