Solution Overview
Problem
Existing swimming pool vacuum systems are either battery-dependent, expensive, bulky, hard to use, or pose electrocution risks, and fail to effectively clean debris that sinks to the bottom of the pool.
Innovation Solution
A continuous external power source swimming pool vacuum system with a detachable vacuum-to-waste assembly that includes a stator assembly with radially protruding fins to guide fluid flow, preventing turbulence and ensuring efficient fluid discharge without interrupting the vacuuming process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a hand-held, battery-operated vacuum system is used, then portability is improved, but operation duration is limited by finite battery life
Solution Approach 1:
The power source is extracted from the vacuum system and placed in a separate, stationary location. The vacuum system itself becomes battery-free and draws power continuously from the external source through the discharge hose, eliminating battery life limitations while maintaining portability of the vacuum unit.
2Productivity
If an in-floor cleaning system or robotic device is used, then cleaning effectiveness is improved, but device complexity and cost increase significantly
Solution Approach 1:
The complex power supply and control systems of robotic or in-floor devices are replaced by extracting the power source to an external location. This simple vacuum system achieves comparable cleaning effectiveness through a straightforward design with a DC pump, filter, and external power connection.
3Duration of action of moving object
If a vacuum system with internal power source is used, then continuous operation is achieved, but electrocution risk increases
Solution Approach 1:
The power source is removed from the vacuum system and placed in a separate, dry location away from water. The vacuum system operates continuously by drawing power through the discharge hose, eliminating electrocution risks associated with internal power sources while maintaining continuous operation capability.
4Productivity
If a vacuum-to-waste assembly is added to discharge filtered water, then fluid management is improved, but device complexity increases
Solution Approach 1:
The vacuum-to-waste assembly is integrated with the vacuum system by combining the discharge hose cap with the vacuum housing. The stator assembly serves dual purposes: guiding fluid flow and providing structural support, eliminating the need for separate components and reducing overall complexity.
Solution Approach 2:
The stator assembly performs multiple functions: it guides fluid flow through the discharge hose cap, provides structural support for the assembly, and works in conjunction with the impeller to optimize water discharge. This multi-functionality reduces the number of separate components needed.

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 system provides a powerful, portable, and safe means to clean pool debris efficiently, with continuous operation and effective fluid management, eliminating the need for battery replacement and reducing the risk of electrocution.
Implementation Method 1
a DC pump disposed within a chamber defined in the housing... The DC pump is configured to move water proximally toward the proximal end portion of the housing
Implementation Method 2
an impeller positioned at the proximal end portion of the housing and configured to rotate in response to an activation of the DC pump
Implementation Method 3
a filter disposed within the housing such that water moves through the filter during activation of the DC pump
Implementation Method 4
The stator assembly includes a conical main body and a plurality of fins protruding radially outward from the main body and extending along a length of the main body. A pair of adjacent fins defines a channel therebetween configured to guide fluid proximally through the discharge hose cap
