Diving Buoyancy Control Valve Manual Override
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modern diving equipment lacks the ability for divers to manually influence the control device's functions, leading to unintended emergency operations, such as automatic inflation of the buoyancy compensator, during activities like holding breath or specific exercises, without the option to manually reset the time control unit.
Innovation Solution
Incorporating additional control valves that allow divers to manually activate or influence the control device and time control unit, using existing inflation and deflation valves, and providing check and reset valves to interrupt or reset emergency operations, enabling intuitive control and adaptation of safety functions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the control device automatically activates emergency operations when the diver stops breathing, then diver safety is improved, but the system cannot be manually influenced by the diver during activities like holding breath or exercises
Solution Approach 1:
The system uses the diver's own breathing actions to automatically reset the time control unit through the existing deflation valve, eliminating the need for separate manual reset controls. The diver's natural breathing pattern serves the dual purpose of both respiratory function and system reset trigger.
Solution Approach 2:
The existing deflation valve is given a dual function: it continues to serve as a buoyancy control valve while also acting as a reset trigger for the time control unit. This eliminates the need for separate reset controls and allows the diver to influence the control device using familiar equipment.
2Adaptability or versatility
If the time control unit is reset automatically through breathing actions, then the system becomes more adaptive to diver activities, but the complexity of the control device increases
Solution Approach 1:
The system leverages the diver's existing breathing actions as the reset mechanism, rather than requiring additional sensors or controls. The breathing actuation of the deflation valve naturally triggers the reset function, making the system adaptive without adding complexity.
Solution Approach 2:
The reset function is merged with the existing breathing detection and deflation valve operation. The same pneumatic pathway and valve actuation mechanism that responds to breathing for buoyancy control also serves to reset the time control unit, combining multiple functions into existing system elements.
3Ease of operation
If additional control valves are added to allow manual influence, then the diver can control emergency operations, but the number of control elements increases
Solution Approach 1:
The deflation valve performs multiple functions: buoyancy control and time control unit reset. By making this existing valve multi-functional, the system provides manual control capability without adding new control elements, thus avoiding increased complexity.
Solution Approach 2:
The control functions are merged into existing valve operations. The deflation valve's actuation mechanism is coupled to both the buoyancy release function and the time control unit reset function, eliminating the need for separate control elements.
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
Enables divers to manually control buoyancy and emergency operations, preventing unnecessary ascents and simplifying operations by using familiar valves, reducing the need for separate control elements and enhancing safety by allowing external intervention by a diving buddy.
Implementation Method 1
the control volume is continuously filled with compressed air from the compressed air cylinder via the filling orifice
Implementation Method 2
a control valve is provided which activates the control device depending on the ambient water pressure
Implementation Method 3
the drain valve is actuated, allowing the control volume to be emptied
Implementation Method 4
Once a defined pressure in the control volume is reached, this causes the emergency valve to be actuated

AI summary
The invention relates to diving equipment, comprising a compressed air bottle (1) which is connected to a breathing apparatus, and an inflatable jacket (2) via which buoyancy can be balanced by the jacket (2) in normal operation being connected to the compressed air bottle (1) in order to be inflated or to an outlet in order to let off air. Furthermore, a monitoring device (8) is provided, which can be activated via a control valve (23) as a function of a surrounding water pressure and has a time monitoring unit (14) which, after the expiry of a defined time and in the event of the absence of breathing activity in the breathing apparatus, changes to emergency operation and activates an emergency valve (9) via a control line (12), which connects the jacket (2) to the compressed air bottle (1) and therefore forces inflation of the jacket (2). In order now to permit the simplest possible manual influencing of the functions of the control device (8), at least one regulating valve is provided, via the respective actuation of which during a dive the monitoring device (8) and/or the control valve (23) can be influenced. In the event of manual activation in normal operation, the jacket (2) is inflated via the inflation valve (3), and the compressed air is let off via the outlet valve (4).
