A modular swimming pool cleaner design with rapidly releasable coupling mechanisms and interchangeable parts, allowing end-users to easily assemble, disassemble, and reconfigure the device without specialized tools, enabling DIY maintenance and upgrades.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If pool cleaners are pre-assembled and manufactured as ready-to-use units, then manufacturing precision and reliability are improved, but ease of repair and maintenance deteriorate
Solution Approach 1:
The pool cleaner is divided into modular components (drive module, brush module, filter module, etc.) that can be independently accessed and replaced. Quick-release coupling mechanisms enable users to segment and replace specific modules without disassembling the entire unit, maintaining reliability while dramatically improving ease of repair.
2Manufacturing precision
If pool cleaners use specialized coupling mechanisms, then manufacturing precision is improved, but ease of operation deteriorates
Solution Approach 1:
The quick-release coupling mechanisms are designed to be operated by end-users without requiring specialized tools or technical expertise. The couplings automatically engage and lock with precise manufacturing tolerances, but can be released by simple user actions such as pressing a button or pulling a release mechanism, thus maintaining manufacturing precision while achieving ease of operation.
3Reliability
If pool cleaners are designed as fixed configuration units, then reliability is improved, but adaptability deteriorates
Solution Approach 1:
The pool cleaner employs a dynamic configuration system where modules can be added, removed, or swapped based on specific cleaning needs. The standardized coupling mechanisms allow the same base unit to adapt to different pool types and cleaning requirements by changing modules, maintaining reliability through proven components while achieving versatility through reconfigurability.
4Reliability
If pool cleaners require professional service for maintenance, then reliability is improved, but loss of time deteriorates
Solution Approach 1:
The system enables end-users to perform maintenance and repairs themselves through intuitive quick-release couplings and clearly marked modules. Users can replace worn brushes, clean filters, or swap out entire modules in minutes without waiting for professional service, significantly reducing downtime while maintaining reliability through proper design guidance.

AI summary
A modular pool cleaning robot is disclosed. The pool cleaning robot includes easily replaceable and/or interchangeable parts and allows for various end-user selectable configurations without the use of tools and without complex and time-consuming large-scale disassembly. Among these parts are a chassis and drive assembly. The drive assembly is removable securable to the chassis via a snap engagement effectuated by pressing the drive assembly against the chassis, without the use of any external fasteners or any tools. The drive assembly detaches from the chassis when a lateral force is exerted on the drive assembly.
