Boat Hull Washing Apparatus Positioning via Water Current
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing boat washing apparatuses face challenges in accurately positioning boats during the washing process, leading to potential inefficiencies and reduced washing quality due to manual mooring, which can result in incorrect alignment with brushes.
Innovation Solution
A boat hull washing apparatus featuring a boat positioning assembly with left and right pushing devices connected to a single force generating unit, allowing for equal lateral forces to hold the boat in a stable position between structures, eliminating the need for separate actuation assemblies and electronic control systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual mooring is used to position the boat, then the apparatus structure remains simple, but the positioning precision deteriorates leading to incorrect alignment with brushes
Solution Approach 1:
The system uses the water current itself as the positioning force. The boat's position is automatically adjusted by the flow of water through the channel, eliminating the need for external actuators or electronic control systems. The channel geometry and water flow naturally guide the boat into the correct position between the brushes.
Solution Approach 2:
The water current acts as an intermediary between the boat and the positioning system. Instead of using mechanical actuators to push or pull the boat, the patent uses the flowing water as a natural mediator to automatically position the boat correctly relative to the brushes.
2Reliability
If separate actuation assemblies are used for each pushing device, then the positioning reliability improves, but the device complexity and cost increase
Solution Approach 1:
The water current automatically performs the positioning function without requiring external actuation assemblies. The system uses the natural flow of water to move and position the boat, eliminating the need for motors, hydraulic systems, or electronic controllers while maintaining reliable positioning.
Solution Approach 2:
The patent extracts and removes the complex actuation systems from the design. By taking out the need for separate motors and control assemblies for each pushing device, the system achieves positioning reliability through the natural water current instead of mechanical actuation.
3Measurement precision
If electronic control systems are implemented for boat positioning, then the positioning precision improves, but the device complexity and cost increase
Solution Approach 1:
The system achieves precise positioning through the self-regulating nature of water flow. The channel geometry and current velocity naturally guide the boat to the correct position without requiring sensors, controllers, or electronic feedback systems. The water flow itself provides the positioning intelligence.
Solution Approach 2:
The patent replaces electronic control systems with a passive mechanical solution based on fluid dynamics. Instead of using motors, sensors, and controllers to position the boat, the system uses the mechanical flow of water through a specifically designed channel to achieve automatic and precise positioning.

AI summary
A boat hull washing apparatus includes a left structure and a right structure, one or more brushes arranged to wash a hull of a boat positioned between the structures. The apparatus is provided with a boat positioning assembly that includes a left and a right boat pushing device. The left and right boat pushing devices are attached to left/right structures respectively. The left boat pushing device is arranged to bias a boat, located between the left and right structures, away from the left structure, and the right device functions similar away from the right structure. In this way, the pushing devices are arranged to hold the boat in a lateral position. Using this arrangement of the left and right pushing devices to bias the boat away from the left and right structures, respectively, a single force generating unit is connected to both pushing devices.
