Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pool cleaning apparatuses have difficulty thoroughly cleaning the waterline at the sidewall of a swimming pool, are time-consuming due to continuous climbing, and have poor cleaning efficiency on this area.
Innovation Solution
A pool cleaning apparatus that can move sideways by controlling the discharging pumps and driving wheels to generate a thrust and rotational speed difference, allowing it to tilt and move along the waterline, thereby enhancing cleaning efficiency and coverage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the existing pool cleaning apparatus climbs upwards and/or downwards continuously on the wall of the pool, then it can clean the wall of the pool, but it is time-consuming and has poor cleaning effect on the waterline
Solution Approach 1:
The pool cleaning apparatus transitions from a static climbing motion to a dynamic sideways movement along the waterline. The apparatus can move horizontally along the pool wall by coordinating the rotation of left and right driving wheels at different speeds, enabling it to traverse the waterline area efficiently without continuous climbing and descending, thus significantly improving cleaning efficiency while reducing time consumption.
Solution Approach 2:
The apparatus introduces a new dimension of movement by enabling sideways motion along the pool wall in addition to the traditional vertical climbing motion. This dimensional change allows the apparatus to access and clean the waterline area more effectively, transforming the cleaning path from purely vertical to a combination of vertical and horizontal movements, thereby improving both cleaning efficiency and reducing time loss.
2Reliability
If the existing pool cleaning apparatus climbs continuously on the wall of the pool, then it can clean the wall, but the waterline cannot be cleaned thoroughly
Solution Approach 1:
The apparatus employs dynamic control of driving wheel rotation speeds to achieve sideways movement along the waterline. By adjusting the rotational speed difference between left and right driving wheels, the apparatus can position itself at various locations along the waterline and maintain stable sideways movement, ensuring thorough cleaning coverage that was previously unachievable with continuous climbing motion alone.
Solution Approach 2:
The pool cleaning apparatus is designed with multi-functionality, capable of performing both traditional vertical climbing cleaning and new sideways movement cleaning along the waterline. This universal design allows the single apparatus to effectively clean multiple areas including the pool wall, waterline, and corners, thereby improving overall cleaning coverage and reliability without requiring additional specialized equipment.
3Reliability
If the pool cleaning apparatus moves sideways by creating thrust and tilting, then it can clean the waterline thoroughly, but the control system complexity increases
Solution Approach 1:
The pool cleaning apparatus uses its existing components (discharging pump and driving wheels) to achieve sideways movement without requiring additional complex mechanical structures. The discharging pump generates thrust by discharging water, and the differential rotation of driving wheels creates tilting motion, allowing the apparatus to self-propel sideways along the waterline using its own built-in systems, thereby minimizing the need for external complex control mechanisms.
Solution Approach 2:
The apparatus achieves sideways movement by changing operational parameters of existing components rather than adding complex mechanical structures. By adjusting the rotation speed parameters of the driving wheels and the discharge parameters of the pump, the apparatus can control its sideways motion and tilting angle, enabling thorough waterline cleaning while keeping the control system relatively simple through parameter adjustment rather than structural complexity.
