Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If water is ejected through a fixed nozzle, then the structure is simple, but the device cannot adjust thrust direction for different cleaning operations
Solution Approach 1:
The patent applies the dynamics principle by making the nozzle rotatable rather than fixed. The second driving unit enables the nozzle to rotate and align its outlet with different discharge openings on the housing, allowing the water ejection direction to be dynamically adjusted for various cleaning operations such as cleaning the bottom, side walls, and water surface of the pool.
Solution Approach 2:
The patent applies segmentation by dividing the discharge function into multiple discrete discharge openings arranged on the housing. Each discharge opening corresponds to a specific cleaning target area, and the nozzle can selectively align with different openings to discharge water in different directions, thereby achieving versatile cleaning capability through segmented discharge paths.
2Adaptability or versatility
If a single discharge opening is used, then the structure is simple, but the device cannot provide thrust in multiple directions for versatile cleaning
Solution Approach 1:
The patent applies universality by designing multiple discharge openings that can serve different cleaning functions. The same water ejection system can clean the bottom, side walls, and water surface by selectively aligning the nozzle with different discharge openings, making the device universally applicable to various cleaning scenarios without requiring separate systems for each surface.
Solution Approach 2:
The patent applies dimensionality change by arranging discharge openings in different spatial orientations on the housing. The discharge openings are positioned to discharge water in different directions (e.g., downward for bottom cleaning, sideways for wall cleaning, upward for surface cleaning), adding spatial dimensionality to the cleaning coverage capability.
3Ease of operation
If the nozzle is fixed in position, then the mechanism is simple, but the device cannot dynamically adjust thrust for different motion states
Solution Approach 1:
The patent applies feedback by using a direction determining unit to detect the current direction of the nozzle outlet and a control unit to process this information. The control unit determines the appropriate discharge opening to align with based on the detected direction and operational requirements, then controls the second driving unit to rotate the nozzle accordingly, creating a closed-loop control system for precise maneuverability.
Solution Approach 2:
The patent applies mechanics substitution by replacing manual adjustment mechanisms with an automated rotation control system. The second driving unit, controlled by the control unit based on operational requirements and motion state, automatically rotates the nozzle to the correct orientation, eliminating the need for manual mechanical adjustment and enabling dynamic adaptation to different cleaning scenarios.
