Electronic Bidet Flush Adapter for Tank and Direct Valve Toilets
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automatic flushing devices for bidets are limited to either water tank toilets or direct flush valve toilets, leading to increased costs due to separate product management and manufacturing, and often suffer from water hammer phenomena and reduced efficiency in low water pressure states.
Innovation Solution
An automatic flushing device for electronic bidets that uses a stepping motor, a roller portion for flushing, and an opening and closing valve to detect user positions and control water flow, allowing for seamless operation in both water tank and direct flush valve toilets, preventing water hammer, and reducing manufacturing complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate bidet products are produced for water tank toilets and direct flush valve toilets, then each product can be optimized for its specific toilet type, but manufacturing costs increase and product management becomes complex
Solution Approach 1:
The bidet is designed with a universal adapter assembly that can be configured for both water tank toilets and direct flush valve toilets. The adapter includes a valve body with multiple ports and internal passages that can route water flow differently depending on the toilet type, allowing a single bidet design to serve multiple toilet configurations without requiring separate product lines.
Solution Approach 2:
The adapter assembly incorporates selectable valve positions or configurable flow paths that can be adjusted or switched between different operating modes. This dynamic configuration allows the same hardware to adapt its water routing behavior to match the specific toilet type being used, enabling one product to function reliably across different toilet systems.
2Quantity of substance
If the water supplying hole of the piston is enlarged to supply water to the bidet, then water supply function is improved, but water hammer phenomenon occurs when the solenoid valve closes
Solution Approach 1:
The adapter assembly introduces an intermediary valve body with controlled flow passages between the toilet's water supply system and the bidet. This intermediary structure regulates water flow to the bidet through its internal passage design, preventing direct connection that would cause water hammer. The valve body acts as a buffer that manages pressure changes and flow transitions smoothly.
Solution Approach 2:
The adapter's valve body design allows water to bypass the problematic direct connection path by routing flow through controlled internal passages. When the solenoid valve closes, the adapter's passage configuration enables water to flow through alternative paths or at reduced velocity, skipping the conditions that generate water hammer and still delivering adequate water supply to the bidet.
3Measurement precision
If water is flushed out through multiple stages (solenoid valve, hot water tank, switching valve), then control precision is improved, but pressure loss occurs and smooth flushing is not achieved
Solution Approach 1:
The adapter assembly extracts the flushing control function from the multi-stage system and consolidates it into a single valve body within the adapter. By taking out the intermediate hot water tank and switching valve from the flushing path, the system reduces the number of stages from three to one, eliminating pressure losses at each interface while maintaining precise control through the adapter's dedicated flush control mechanism.
Solution Approach 2:
The adapter merges multiple functions (water supply regulation, flush control, and bidet operation) into a single integrated valve body. This consolidation eliminates the need for separate hot water tank and switching valve in the flushing path, reducing pressure losses while maintaining control precision through the unified valve's coordinated internal passages and control mechanisms.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables a single product to be used across both toilet types, reducing manufacturing costs and improving efficiency, ensuring smooth flushing regardless of water pressure, and enhancing safety by integrating the stepping motor within the bidet.
Implementation Method 1
a stepping motor configured such that whether a user is in a sitting position or a standing up position is detected by a control unit of the electronic bidet and the stepping motor is rotated by a control signal set from the control unit
Implementation Method 2
a roller portion for flushing mounted at a rotary shaft of the stepping motor, the roller portion for flushing being configured such that a roller is rotated by the control signal of the control unit and a wire is wound and unwound, thereby opening and closing a water sealing cover or pressing an opening and closing valve
Implementation Method 3
the opening and closing valve being configured such that a flow path of a valve body is open by a rotation of a pressing member when the opening and closing valve is applied to the direct flush valve toilet, thereby discharging water in a pressure chamber of a flush valve to an inner portion of a toilet body and flushing out the water

AI summary
Proposed is an automatic flushing device for an electronic bidet, in which the automatic flushing device has an automatic flushing function and is for both a water tank toilet and a direct flush valve toilet. In contrast to existing bidets, which are produced separately for the water tank toilet and the direct flush valve toilet in order to enable the automatic flushing function of the water tank toilet and the direct flush valve toilet, the automatic flushing device for the electronic bidet enables a single bidet to be capable of being used in both the water tank toilet and the direct flush valve toilet.
