Toolless Chassis Housing for Automatic Pool Cleaners
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automatic swimming pool cleaners lack a mechanism for easy assembly and disassembly without tools, which complicates customization, maintenance, and production processes.
Innovation Solution
The design incorporates a chassis with interchangeable housings that can be attached and detached toollessly, featuring engagement features such as teeth and ribs, and a flow outlet that attaches to a motor block, allowing for facile disassembly and customization of the cleaner.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional fixed construction is used, then structural stability is maintained, but assembly and disassembly require tools and time
Solution Approach 1:
The cleaner is divided into modular components (chassis, housing, motor assembly, flow outlet) that can be independently assembled and disassembled. The housing can be detached from the chassis without tools, enabling easy access to internal components and facilitating maintenance or customization activities.
Solution Approach 2:
The connection between housing and chassis transitions from a fixed state to a dynamically adjustable state, allowing the housing to be easily attached and detached. This dynamic connection enables the system to adapt between assembled and disassembled configurations based on operational needs.
2Adaptability or versatility
If components are permanently fixed, then manufacturing precision is maintained, but customization and maintenance become difficult
Solution Approach 1:
The cleaner is divided into modular components (chassis, housing, motor assembly, flow outlet) that can be independently assembled and disassembled. The housing can be detached from the chassis without tools, enabling easy access to internal components and facilitating maintenance or customization activities.
Solution Approach 2:
The chassis serves as a universal base that can accommodate different housing configurations and motor assemblies. The standardized interface allows various components to be interchanged while maintaining proper alignment and functionality, enabling customization without sacrificing precision.
3Productivity
If tool-based assembly is used, then connection strength is ensured, but production and maintenance time increase
Solution Approach 1:
The housing and chassis are designed with self-aligning features that enable tool-free assembly and disassembly. The complementary geometries of the components guide proper positioning during assembly, eliminating the need for external tools while maintaining adequate connection strength for operational requirements.
4Ease of operation
If housing is permanently attached, then structural integrity is maintained, but access to internal components is limited
Solution Approach 1:
The cleaner is divided into modular components (chassis, housing, motor assembly, flow outlet) that can be independently assembled and disassembled. The housing can be detached from the chassis without tools, enabling easy access to internal components and facilitating maintenance or customization activities.
Solution Approach 2:
The connection between housing and chassis transitions from a fixed state to a dynamically adjustable state, allowing the housing to be easily attached and detached. This dynamic connection enables the system to adapt between assembled and disassembled configurations based on operational needs.

AI summary
Automatic swimming pool cleaners (APCs) may include separate chassis and bodies. Such constructions may facilitate assembly and disassembly of certain components of the APCs, with or without using tools. APCs with separate chassis and bodies may enable quick and easy access to motor assemblies of the APC, and bodies of the APCs may be readily interchanged on a common chassis.
