Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If traditional pool cleaners are used, then cleaning function is provided, but they require external power sources and complex wiring systems
Solution Approach 1:
The patent replaces electrical propulsion systems with a mechanical propeller-driven system that operates autonomously on the pool floor. The cleaner uses a propeller mechanism to generate thrust for movement and cleaning operations, eliminating the need for complex wiring and external power sources while maintaining cleaning effectiveness.
Solution Approach 2:
The pool cleaner is designed to be self-propelled and self-operating using the propeller system. It autonomously navigates the pool floor, performs cleaning operations, and returns to its starting position without requiring external control or power intervention, making it self-sufficient in operation.
2Ease of operation
If pool cleaners are designed with propellers, then self-propulsion is achieved, but manufacturing complexity increases
Solution Approach 1:
The pool cleaner is divided into modular components including the propeller assembly, cleaning mechanism, and housing. This segmentation allows for simplified manufacturing of individual parts that can be assembled together, reducing overall manufacturing complexity while maintaining the self-propelled functionality.
Solution Approach 2:
The patent optimizes the propeller design parameters such as blade angle, diameter, and pitch to achieve efficient propulsion with simple manufacturing requirements. By carefully selecting these parameters, the system achieves autonomous operation without requiring complex manufacturing processes.
3Productivity
If the cleaner is designed to return to start position, then operational completeness is improved, but energy consumption increases
Solution Approach 1:
The pool cleaner operates in periodic cycles, performing cleaning operations at the pool floor and then returning to the start position. This periodic operation allows the system to complete full cleaning cycles efficiently, using energy only when necessary for propulsion and cleaning rather than continuous operation.
Solution Approach 2:
The cleaner performs the essential cleaning function at the pool floor and then executes a minimal return trip to the start position. By focusing energy on the productive cleaning action rather than continuous movement, the system achieves operational completeness with optimized energy consumption.
