Dive Computer Free Dive Mode Nitrogen Loading
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Dive computers do not effectively account for nitrogen loading during free dives, leading to unnecessary waiting periods before subsequent scuba dives, as they typically disable functions after a free dive to ensure nitrogen levels return to normal.
Innovation Solution
A dive computer with a free dive mode that calculates nitrogen loading using a default oxygen fraction, allowing divers to resume scuba diving without waiting, by incorporating a pressure transmitter system for real-time pressure monitoring and communication, enabling immediate resumption of dives after free diving.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the dive computer is disabled after a free dive to ensure nitrogen levels return to normal, then safety is improved, but the waiting time before subsequent scuba dives increases
Solution Approach 1:
The patent changes the parameter of nitrogen loading calculation by using a default oxygen fraction (21%) specific to free dive conditions rather than standard scuba diving parameters. This allows the dive computer to accurately calculate nitrogen loading during free dives and determine when a diver is ready for subsequent scuba diving without unnecessary waiting periods, while still maintaining safety through accurate nitrogen tracking.
2Ease of operation
If the dive computer uses standard nitrogen loading calculations for free dives, then ease of operation is improved, but measurement precision deteriorates
Solution Approach 1:
The patent applies local quality by using a specific default oxygen fraction (21%) that is locally optimized for free dive conditions. This localized parameter improves the accuracy of nitrogen loading calculations during free dives without requiring complex user input or configuration, maintaining ease of operation while enhancing measurement precision for the specific free dive scenario.
3Reliability
If the dive computer disables functions after a free dive, then reliability is improved, but productivity deteriorates
Solution Approach 1:
The patent implements feedback by continuously monitoring nitrogen loading during free dives and using this information to determine when a diver is ready for subsequent scuba diving. The dive computer provides real-time feedback on nitrogen levels and allows divers to resume diving activities as soon as safety thresholds are met, eliminating unnecessary waiting periods and improving overall dive productivity while maintaining reliability through continuous nitrogen tracking.

AI summary
A dive computer with a free dive mode and/or wireless data transmission capabilities. In one embodiment the invention relates to a diving apparatus including a dive computer having a free dive mode, where the dive computer is configured to calculate a nitrogen loading in the free dive mode using a default value which is the fraction of oxygen in air, and where the free dive mode is used when a diver makes a dive without a self-contained underwater breathing apparatus. Another embodiment includes a method of operating a dive computer including recording two or more first identifiers, receiving pressure information from two or more pressure transmitters, the pressure information comprising second identifiers and pressure measurements, determining whether the pressure information contains one of the two or more first identifiers, and displaying a message indicative of the pressure information that contains one of the two or more first identifiers.
