Innovation Solution
A portable pool cleaner design with a remote wearable battery pack and waterproof connections to a pump and lighting element, allowing efficient cleaning without the need for external carts and enhancing visibility with an integrated illumination device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a self-contained suction assembly with battery and pump is used in manual pool cleaners, then the cleaner can operate independently without external power sources, but the power supply capacity is limited due to space constraints and water leakage risks
Solution Approach 1:
The system is divided into two separate components: a lightweight pool cleaner unit that remains in the pool, and a remote wearable battery pack that the user carries outside the pool. This segmentation allows the power supply to be located where space is not constrained by the pool environment, enabling higher capacity batteries without increasing the size of the cleaner head.
Solution Approach 2:
A waterproof connector acts as an intermediary between the pool cleaner and the wearable battery pack, transmitting electrical power while maintaining isolation between the electrical components and water. This allows reliable power transmission without compromising the waterproof integrity or risking water leakage into the battery compartment.
2Power
If a larger battery pack is installed in the pool cleaner to increase power output, then the cleaner can operate more effectively, but the device becomes heavier and less portable
Solution Approach 1:
By separating the battery pack from the cleaner unit and placing it on the user's body, the weight of high-capacity batteries is transferred from the moving cleaner to the stationary user. This allows the cleaner to remain lightweight and easily maneuverable while still receiving sufficient power from the larger battery pack.
3Power
If the cleaner design allows for larger power supplies, then cleaning effectiveness improves, but the risk of water leakage into the power supply increases
Solution Approach 1:
The battery pack and electrical power supply are extracted from the pool cleaner unit and placed in a separate wearable component that remains outside the water. This eliminates the risk of water leakage into the power supply entirely, as the electrical components are no longer in proximity to the pool water, while still providing adequate power through the waterproof connector.
4Device complexity
If manual vacuuming and brushing is used to clean pool surfaces, then no additional power supply is needed, but cleaning efficiency and effectiveness are reduced
Solution Approach 1:
The pool cleaner performs the cleaning function autonomously through the action of the pump and filtration system, eliminating the need for manual vacuuming and brushing. The user simply guides the cleaner through the pool while wearing the battery pack, allowing the device to do the work that would otherwise require significant manual effort.
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
The portable design enables efficient debris removal and filtration with improved mobility and visibility, reducing the need for manual vacuuming and brushing, while preventing water damage to the power supply.
Implementation Method 1
A pump is housed within the body chamber drawing fluid from the intake end and expelling the fluid through the discharge end
Implementation Method 2
A filter is placed within the body chamber filtering out particulates from the fluid drawn into the body chamber
