Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current scuba diving equipment is complex, cumbersome, and requires extensive preparation and maintenance, making it difficult for non-professional divers to engage in safe and frequent diving activities, especially at shallow depths, and does not accommodate the 'yo-yo diving' technique which involves alternating descents and ascents.
Innovation Solution
A self-contained underwater breathing apparatus designed to be compact, lightweight, and easy to use, featuring a pre-assembled watertight container enclosure that can be worn like a backpack, with a built-in pressure reducer and rechargeable batteries, and integrated buoyancy control means, allowing for simplified preparation and maintenance, and versatility in diving techniques up to 12 meters depth.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional scuba diving equipment is used, then diving safety and reliability are ensured, but device complexity and preparation time increase significantly
Solution Approach 1:
The patent combines multiple separate diving equipment components (air store, pressure reducer, buoyancy control means, regulator) into a single integrated self-contained unit. This merging eliminates the need for separate assembly operations while maintaining all necessary safety functions, directly resolving the contradiction between reliability and device complexity.
Solution Approach 2:
The integrated apparatus is designed to support multiple diving techniques including both traditional surface-bottom-surface diving and yo-yo diving with alternating descents and ascents. The universal design allows a single device to handle various diving scenarios without requiring separate equipment configurations, reducing preparation complexity while ensuring safety across different operating conditions.
2Reliability
If traditional scuba diving equipment is assembled each time, then proper configuration is ensured, but preparation time and operational complexity increase
Solution Approach 1:
The apparatus is pre-assembled and pre-configured before delivery to the user, with all components integrated and tested. This preliminary action eliminates the need for users to perform assembly operations at each diving session, reducing preparation time to zero while maintaining correct configuration through factory-quality assembly standards.
Solution Approach 2:
The self-contained design allows the apparatus to be used independently without requiring user assembly or configuration operations. The integrated structure provides self-sufficiency, where the device serves itself by being ready-for-use out-of-the-box, eliminating the time-consuming preparation activities required by traditional separate components.
3Adaptability or versatility
If equipment is designed for deep diving, then maximum depth capability is achieved, but weight and manageability worsen for shallow water use
Solution Approach 1:
The apparatus incorporates adjustable buoyancy control means that can be dynamically adjusted for different operating depths. The buoyancy system can be configured for shallow water operations or deep water operations as needed, allowing the same device to adapt to different depth requirements without requiring separate equipment for each scenario, thus maintaining versatility while optimizing weight for the intended use.
