Solution Overview

Problem

Existing bidet sprayers lack an efficient and aesthetically pleasing design for water distribution, with limited options for nozzle configurations and interference issues when transitioning between active and inactive positions.

Innovation Solution

A bidet sprayer system featuring a centrally located spray head with two independently controlled nozzle groups, a modular design allowing for easy replacement, and a mechanism for translational, rotational, or telescopic movement to optimize water distribution and minimize interference.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a traditional single-nozzle spray head is used, then the device complexity is low, but the adaptability and cleaning versatility are limited

Engineering Contradiction:
Improvecleaning versatilityVSAvoiddevice complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The spray head is divided into multiple independent nozzle groups (first nozzle group and second nozzle group) with different spray patterns. Each nozzle group can be independently controlled through separate water supply lines, allowing the system to provide multiple cleaning modes (e.g., rinse mode, wash mode, massage mode) without increasing overall system complexity significantly.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The spray head assembly is designed to perform multiple cleaning functions through different nozzle configurations. The same physical spray head structure can deliver various spray patterns (full spray, partial spray, concentrated spray) by activating different nozzle groups, making it universally applicable for different cleaning needs.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Shape

If the spray head is centrally located on the wand, then the aesthetics and water distribution are improved, but the ease of maintenance and replacement becomes difficult

Engineering Contradiction:
ImproveaestheticsVSAvoidease of maintenance
Core Design Contradiction:
ShapeVSEase of repair

Solution Approach 1:

The spray head is designed as a separable component that can be easily detached from the wand assembly. The connection interface between the spray head and wand is configured to allow simple removal and reattachment, enabling users to maintain or replace the spray head without complex disassembly procedures, thus preserving both aesthetics and ease of maintenance.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The spray head is extracted as an independent, removable module from the wand assembly. This allows the spray head to be easily removed for cleaning, maintenance, or replacement while the wand remains in place, solving the contradiction between centralized aesthetic positioning and ease of maintenance.

Inventive Principle:
Principle #2Taking out (Extraction)

3Adaptability or versatility

If the spray head is fixed on the wand, then the reliability is high, but the adaptability for different cleaning positions is limited

Engineering Contradiction:
Improveposition adaptabilityVSAvoidconnection reliability
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The spray head connection to the wand is designed with dynamic characteristics, allowing for easy attachment and detachment while maintaining a secure connection during use. The connection mechanism provides reliable fixation during operation but enables quick removal when needed, balancing reliability with adaptability for different cleaning positions and maintenance requirements.

Inventive Principle:
Principle #15Dynamics

AI summary

A bidet includes one or more water sources, a generally elongate wand, and a spray head. The wand is configured to communicate water from the one or more water sources to the spray head. The spray head is configured to spray the water received from water sources, and the spray head is also configured to releasably couple to the wand by being received through an upper surface of the wand into a receptacle thereof.
