Removable NFC Watch Bezel for Easy Replacement and Water-Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing near-field communication devices in watches have a limited service life due to the integrated circuit's lifespan, necessitating complex and expensive maintenance that often requires replacing other watch parts, which is difficult and costly.
Innovation Solution
A watch case design with a removable bezel that houses the near-field communication device, using a reversible fastening system and dielectric materials to allow easy replacement and maintenance without affecting water-resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the near-field communication device is integrated into the watch case using conventional methods, then the communication function is achieved, but the maintenance and replacement of the device becomes complex and expensive
Solution Approach 1:
The bezel is divided into two separate lining elements (first and second lining elements) that can be disassembled from each other. The near-field communication device is housed within a cavity formed by these two elements, allowing the device to be accessed and replaced by simply separating the lining elements without affecting other watch components. This segmentation enables independent maintenance of the communication device while preserving the integrity of the rest of the watch.
2Ease of repair
If the bezel is made removable to facilitate maintenance, then ease of repair is improved, but water-resistance may be compromised
Solution Approach 1:
A tightening element acts as an intermediary component between the first and second lining elements. This tightening element creates a secure mechanical connection that maintains the water-tight seal when the lining elements are assembled together. The tightening element enables the bezel to be both removable for maintenance and water-resistant during operation, resolving the contradiction between accessibility and protection.
3Stability of the object's composition
If the near-field communication device is permanently integrated into the watch case, then structural integrity is maintained, but replacement of the device requires complex procedures
Solution Approach 1:
The bezel structure transitions from a static, permanently integrated design to a dynamic, modular configuration. The two lining elements can be assembled and disassembled as needed, allowing the near-field communication device to be replaced quickly when maintenance is required. The tightening element ensures that when assembled, the structure maintains its integrity comparable to a permanent integration, thus balancing structural stability with maintenance efficiency.

Function Achieved in This Case
Enables easy and cost-effective maintenance of near-field communication devices in watches, preserving the watch's integrity and water-resistance.
Implementation Method 1
said second lining element comprises a reversible connecting area that could cooperate by friction with a tightening element arranged in a groove comprised within the first lining element
Implementation Method 2
the first and second lining elements, the removable support element and the tightening element are made of at least one dielectric and/or electrically non-conductive material
