Diving Watch Bezel and Dedicated Hand for Direct Dive Time Reading
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing diving watches do not allow divers to directly determine their dive time accurately without mental calculations for dives longer than one hour, posing a safety risk.
Innovation Solution
A diving watch with a dedicated hand and rotating bezel that provides an instantaneous dive time indication, allowing easy visual reading of elapsed dive time through a second analog display device with a unique angular velocity and luminescent features.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If existing diving watches display time data, then the diver can see time information, but the diver cannot directly determine dive time without mental calculations when it exceeds one hour
Solution Approach 1:
The watch face is segmented into distinct functional zones: a first display device for current time and a second display device for dive time. The second device includes a dedicated dive time hand and a rotating bezel with time scale, creating visually separated information channels that prevent confusion and enable direct reading of dive time without calculation.
Solution Approach 2:
A dedicated dive time hand acts as an intermediary element that directly indicates dive time on the rotating bezel. This specialized hand, with distinct visual characteristics (different color or shape), serves as a mediator between the timekeeping mechanism and the diver, providing immediate dive time information without requiring the diver to perform calculations.
2Reliability
If the diver focuses on managing oxygen consumption and decompression stops, then diver safety improves, but the diver must perform mental calculations to determine dive time
Solution Approach 1:
The rotating bezel serves multiple functions: it acts as a time scale for the dedicated dive time hand, provides visual reference markings for dive time intervals, and can be rotated to reset or adjust the display. This multi-functional element reduces the need for separate components while maintaining clear dive time indication.
Solution Approach 2:
The dedicated dive time hand and corresponding time scale markings use distinct colors or luminescent materials that differ from the main time display elements. This color differentiation creates immediate visual distinction between current time and dive time information, allowing the diver to quickly identify dive time without cognitive processing.
3Measurement precision
If a dedicated hand with unique angular velocity is used to indicate dive time, then instantaneous dive time value is displayed, but the watch mechanism becomes more complex
Solution Approach 1:
The movement mechanism integrates the dedicated dive time hand's rotation with the existing timekeeping gears. The dedicated hand completes rotations at a different angular velocity to match the dive time scale on the bezel, but shares the same central mounting and power source as the main time hands, reducing the need for completely separate mechanical systems.
