Solution Overview
Problem
Existing underwater propellers, hydrofoil board boosters, and diving assist devices are limited to single scenarios, lack auxiliary power, and have inadequate battery capacity, making them inconvenient for multiple usage scenarios and requiring multiple equipment purchases.
Innovation Solution
A propeller with a detachable propulsion structure, foldable blades, and a modular battery system that can be easily switched between different usage scenarios, including hydrofoil boards and diving apparatuses, and provides adjustable battery capacity from 99 Wh to 297 Wh.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single-purpose propeller design is used, then the device structure is simple, but the adaptability to different usage scenarios is limited
Solution Approach 1:
The propeller is divided into separate modular components: a main body unit, a propulsion structure, and a battery unit. Each component can be independently selected and combined to create different usage scenarios, allowing one device to serve multiple purposes without requiring complete structural redesign.
Solution Approach 2:
The main body unit is designed with universal mounting interfaces that can accommodate different propulsion structures (handheld propeller, hydrofoil board booster, diving assist device) and battery configurations, enabling a single base device to perform multiple functions across different sports and activities.
2Duration of action of moving object
If battery capacity is increased to extend endurance, then the operating duration is improved, but the portability and air travel convenience deteriorate
Solution Approach 1:
The battery system is segmented into removable battery units that can be independently attached to or removed from the main body. Users can select battery units with different capacities based on their specific needs, attaching multiple units for extended endurance or using a single unit for shorter durations and improved portability.
Solution Approach 2:
The battery configuration is made dynamic and adjustable rather than fixed. Users can change the battery capacity configuration based on the duration of the activity, switching between different battery unit combinations to optimize between endurance and portability requirements for each specific use case.
3Ease of operation
If fixed propulsion structure is used, then the device is simple to manufacture, but the ease of switching between different propulsion types deteriorates
Solution Approach 1:
The propulsion system is segmented into separate propulsion structures that can be independently attached to and removed from the main body. Each propulsion structure (handheld propeller, hydrofoil board booster, diving assist device) is designed as a distinct module with standardized interfaces, enabling easy switching between different propulsion types without complex manufacturing requirements.
Solution Approach 2:
The main body unit incorporates universal mounting mechanisms that accommodate multiple types of propulsion structures through standardized interfaces. This universality allows users to switch between different propulsion types for different activities without requiring custom manufacturing for each configuration, balancing ease of switching with manufacturing simplicity.

AI summary
Disclosed is a propeller, including a main driving device. Foldable blades and a fixed propeller are detachably connected to a projecting shaft of a driving motor. When the foldable blades are arranged, the propeller can be used as a hydrofoil board booster, and be clamped to a vertical rod of the hydrofoil board. When a fixed propeller is surrounded by a water flow culvert pipe provided with water inlet grooves, the propeller can be handheld with a handheld bracket or worn to advance and play underwater. Further, the propeller can be used as a guiding device for a diving apparatus. In combination with a gas cylinder and an airbag, the propeller can also be used as a scuba gear. Together with movable and fixed hydrofoil boards, the propeller can also be used as a gliding apparatus for diving.
