Sonic Pool Brush Oscillating Segments Reduce Operator Fatigue
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Standard pool brushes are inefficient in removing foreign materials from the sides and bottom of swimming pools, requiring significant downward pressure and effort, and often fail to dislodge materials in areas like the center of the pool.
Innovation Solution
A sonic pool brush with oscillating brush segments powered by electric motors, operating in the sonic range (20 Hz to 20,000 Hz), which eliminates the need for downward pressure by using sonic vibrations to scrub and remove debris with minimal operator effort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If downward pressure is applied to the brush to remove foreign materials, then cleaning effectiveness is improved, but operator fatigue increases significantly
Solution Approach 1:
The patent applies mechanical vibration by using an electric motor to oscillate the brush segment at sonic frequencies (20 Hz to 20,000 Hz). This vibration creates a scrubbing action that removes foreign materials from pool surfaces without requiring the operator to apply significant downward pressure, thereby maintaining cleaning effectiveness while reducing operator fatigue
Solution Approach 2:
The patent replaces the manual mechanical system (operator applying downward pressure) with an automated mechanical system (electric motor generating oscillating motion). The motor-driven oscillation substitutes for human physical effort, transforming the cleaning mechanism from pressure-dependent to vibration-dependent
2Reliability
If downward pressure is applied to the brush to stir-up clinging materials, then material removal is improved, but the operator experiences extreme fatigue
Solution Approach 1:
The electric motor oscillates the brush segment at sonic frequencies, creating high-velocity vibrations that stir-up and dislodge foreign materials clinging to pool surfaces. This vibrational action achieves material removal without requiring the operator to apply extreme downward pressure
Solution Approach 2:
The patent changes the operating parameter from static pressure to dynamic oscillation frequency. By operating in the sonic range (20 Hz to 20,000 Hz), the brush segment generates sufficient kinetic energy to dislodge materials through vibration rather than through applied pressure
3Ease of operation
If standard brush movement is used to clean pool surfaces, then the brush can reach all areas, but it only skims over material leaving it clinging to surfaces
Solution Approach 1:
The oscillating brush segment creates a scrubbing and stirring action that penetrates through skimmed material to dislodge foreign substances clinging to pool surfaces. The sonic vibrations enhance the cleaning action beyond what simple brush movement can achieve
Solution Approach 2:
The electric motor provides continuous periodic oscillation of the brush segment, creating repeated scrubbing cycles as the brush moves across pool surfaces. This periodic vibrational action ensures thorough material dislodgment while maintaining brush mobility
4Reliability
If downward pressure is applied in center pool areas to remove materials, then cleaning effectiveness is improved, but it becomes literally impossible to apply pressure in some areas
Solution Approach 1:
The patent replaces the need for operator-applied pressure with motor-generated oscillating force. This substitution allows the brush to effectively clean pool surfaces including center areas where applying downward pressure would be impossible or extremely difficult
Solution Approach 2:
By changing from pressure-based cleaning to vibration-based cleaning, the system overcomes the physical limitation of applying pressure in certain pool areas. The sonic oscillations provide sufficient cleaning force without requiring the operator to push down on the brush
