Innovation Solution
A self-contained, backpack-wearable hookah system with automated setup, including miniature pH sensors for data collection, automatic flotation tube inflation, and a wireless warning system, which eliminates the need for lead weights and enhances portability and data recording capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If traditional gasoline-powered hookah systems are used, then air supply capability is achieved, but system weight and bulk increase significantly
Solution Approach 1:
The patent replaces the traditional gasoline-powered mechanical compression system with an electrically-driven compression system. The electric motor (150-500W) drives the air compressor (250-750 LPM capacity) to provide air supply, eliminating the need for heavy gasoline engines while maintaining adequate air delivery capability for recreational diving applications.
Solution Approach 2:
The patent changes the power source parameters from high-power gasoline engines to lower-power electric motors (150-500W), and from lead-acid batteries to lithium-ion battery packs. This parameter change reduces system weight and bulk while providing sufficient air supply for shallower recreational diving (20-40 feet depth).
2Weight of moving object
If flotation tube is manually inflated, then portability is improved, but setup time and ease of operation deteriorate
Solution Approach 1:
The system performs preliminary action by automatically inflating the flotation tube (8) as part of the automated setup sequence. When the system is powered on, the microcontroller automatically activates the air compressor to inflate the flotation tube before the diver enters the water, eliminating the need for manual inflation and reducing setup time.
Solution Approach 2:
The system performs self-service through automated setup functions. The microcontroller (52) automatically controls the air compressor (10) to inflate the flotation tube (8) and regulate air pressure in the air hose (29) based on depth sensor input, without requiring manual intervention from the diver.
3Reliability
If extensive gear is carried for hookah diving, then air supply reliability is improved, but device complexity and portability worsen
Solution Approach 1:
The patent merges multiple previously separate components into a single integrated surface unit. The air compressor (10), lithium-ion battery pack (12), flotation tube (8), control electronics (52), and sensor systems are combined into one unified device, eliminating the need for separate gear bags and reducing overall system complexity while maintaining air supply reliability.
Solution Approach 2:
The surface unit serves multiple functions: air compression, power supply (lithium-ion battery), flotation, data collection (sensors), and automated control. This multi-functionality reduces the number of separate components needed while ensuring reliable air supply for the diver.
4Weight of moving object
If brushless DC motors are used instead of brushed DC motors, then system weight is reduced, but cost increases
Solution Approach 1:
The patent specifies using brushless DC motors (150-500W) instead of brushed DC motors, representing a parameter change in motor technology. This change reduces system weight and improves efficiency, with the cost increase being acceptable given the overall system design goals for recreational diving applications.
5Ease of operation
If automated setup functions are implemented, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The automated setup system uses feedback from depth sensors (62) and pressure sensors (53, 55) to automatically adjust air compressor operation and air hose pressure. The microcontroller continuously monitors sensor inputs and adjusts compressor speed and valve operation to maintain appropriate pressure levels, providing automated control without excessive complexity.
