Sanitary Cleansing Device Nozzle Alignment Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users experience discomfort and insecurity when using sanitary cleansing devices with wide cleansing modes, as they cannot visually confirm the alignment of the spray port with the intended cleansing area, leading to unwanted wetting of thighs or underwear, especially when the water splash area is expanded laterally.
Innovation Solution
A sanitary cleansing device with a nozzle assembly that sprays water obliquely upward, a drive device for moving the water splash point in both front-to-back and lateral directions, and a control system that initiates a fixed spot cleansing mode at the reference position before transitioning to a wide movement mode, ensuring proper alignment and minimizing uncomfortable wetting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the water splash area is expanded laterally to widen the cleansing area, then the cleansing coverage is improved, but the user experiences discomfort and insecurity due to inability to visually confirm spray alignment
Solution Approach 1:
The spray port performs fixed-spot spraying at the reference private area position for a predetermined period before executing wide-area movement. This preliminary action allows users to visually confirm proper alignment and positioning, eliminating insecurity about spray direction, before expanding the water splash area laterally to enhance cleansing coverage.
2Area of stationary object
If the spray port is positioned to cover a wide area, then cleansing coverage is improved, but the user cannot recognize whether seating position is correctly aligned with the spray
Solution Approach 1:
The system first positions the spray port at the reference private area position and performs fixed-spot spraying, allowing users to visually confirm proper alignment and seating position. Only after this preliminary alignment confirmation does the system expand to wide-area movement, ensuring users have visual feedback about correct positioning before full cleansing coverage is activated.
3Productivity
If the nozzle moves in multiple directions to expand water splash point coverage, then cleansing effectiveness is improved, but the risk of wetting unintended areas increases
Solution Approach 1:
The spray port first executes fixed-spot spraying at the reference position to establish proper alignment and allow visual confirmation. Only after this preliminary phase does the system activate multi-directional movement to expand water splash coverage, thereby ensuring cleansing effectiveness while minimizing the risk of water flowing to unintended areas.
Solution Approach 2:
The nozzle assembly dynamically adjusts its operation mode, transitioning from a static fixed-spot position to dynamic multi-directional movement. This dynamic control allows the system to first establish proper alignment at a controlled position, then safely expand coverage area through controlled movement in front-to-back and right-to-left directions.

AI summary
Provided is a sanitary cleansing device configured to less provide a feeling of insecurity to a user when a cleansing mode for moving a water splash point in at least two directions is used. The present invention provides a sanitary cleansing device (1) including a nozzle assembly (6) provided with a spray port, a nozzle drive device (12), an operation device (10) operated by a user to switch a cleansing mode, and a spray control device (20) configured to switchably execute, a fixed spot cleansing mode in which the spray port is stopped at a predetermined reference private area position and a wide movement cleansing mode for moving a water splash point in at least two directions. When the wide movement cleansing mode begins, the spray port is positioned at the reference private area position, and then, starts movement of the water splash point.
