Pool Cleaner Steering Cam for Independent Wheel Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional pool cleaners lack independent control of drive wheel rotation directions and continuous cleaning capability regardless of travel direction, often introducing complexity in manufacturing, assembly, and maintenance.
Innovation Solution
A pool cleaner system featuring a rotating cam with distinct cam profiles for each drive wheel, allowing independent control of wheel rotation directions through actuators that engage forward and reverse drive-change gears, enabling forward, reverse, and turning movements with a single cam.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single cam with different cam profiles is used to control multiple drive wheels, then independent control of wheel rotation directions is achieved, but the device complexity is reduced compared to multiple separate cams
Solution Approach 1:
Multiple separate cam mechanisms are merged into a single cam with multiple different cam profiles. The cam includes a first cam profile for controlling a first drive wheel and a second cam profile for controlling a second drive wheel, both on the same cam structure. This consolidation reduces the number of separate components from multiple cams to a single cam, simplifying manufacturing and assembly while maintaining independent control capability.
Solution Approach 2:
The single cam structure is designed to perform multiple functions by incorporating different cam profiles for controlling different drive wheels. Each cam profile can be independently configured to control the rotation direction of its corresponding drive wheel, allowing the single cam to replace multiple specialized cam mechanisms while maintaining the versatility needed for independent wheel control.
2Ease of operation
If separate drive wheels can be rotated independently, then steering capability is improved, but the vacuum system complexity increases in conventional cleaners
Solution Approach 1:
The drive system and vacuum system are merged into an integrated unit where the same turbine that drives the drive wheels also powers the vacuum function. The turbine is coupled to both the cam mechanism for wheel rotation control and the vacuum system, eliminating the need for separate power transmission systems and reducing overall system complexity while enabling independent steering control.
3Productivity
If continuous cleaning capability is maintained during all movements including reverse and turn, then productivity is improved, but the device complexity increases without the single cam system
Solution Approach 1:
The system maintains continuous useful action by ensuring the vacuum function operates continuously regardless of the drive wheel rotation state. The turbine continues to rotate and generate vacuum pressure even when the cam mechanism is executing reverse or turning movements, allowing the cleaner to continuously pick up debris during all phases of motion without requiring additional mechanisms to maintain cleaning capability.

AI summary
Embodiments provide a pool cleaner with a housing, a first drive wheel positioned along a first side of the housing, and a second drive wheel positioned along a second side of the housing. The pool cleaner also includes a steering system engaged with the first drive wheel and the second drive wheel. The steering system includes a rotating cam with a first cam profile and a second cam profile different from the first cam profile. The steering system drives the housing in a cycle of forward and turn movements by rotating the first drive wheel based on the first cam profile and rotating the second drive wheel based on the second cam profile.
