Solution Overview
Problem
Existing sensory flushing devices for toilets are unreliable during power outages and have short lifespans in humid environments, leading to inadequate functionality, and combining manual and sensory flushing solutions results in high costs and complex constructions.
Innovation Solution
A flushing device with combined manual and sensory flushing capabilities, utilizing a body signal receiving device, PCB control device, and air pump, along with normally closed and open valves and inflation mechanisms, allowing the air bag to be connected either with the air pump or inflation mechanism for sensory or manual activation, ensuring seamless operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If sensory flushing devices are used in humid sanitary environments, then automated flushing functionality is achieved, but device lifespan is reduced due to moisture damage
Solution Approach 1:
The system is divided into two independent flushing pathways: an electronic-controlled sensory flushing path (with solenoid valve) and a manual mechanical flushing path (with manual valve and pump). This segmentation allows the electronic components to be isolated from direct exposure to humid environments while maintaining automated functionality through the sensor-triggered solenoid valve activation.
Solution Approach 2:
The patent changes the operational state parameters of the valves based on flushing mode. During manual flushing, the manual valve opens while the solenoid valve closes, directing air flow through the manual path. During sensory flushing, the solenoid valve opens while the manual valve closes, directing air flow through the automated path. This parameter switching protects electronic components by keeping them in a closed, protected state during manual operations.
2Adaptability or versatility
If manual and sensory flushing solutions are combined using two complete independent devices, then both flushing modes are available, but construction complexity and space requirements increase
Solution Approach 1:
The patent merges manual and sensory flushing systems into a single integrated device by sharing common components including the air pump, air bags, control unit, and valve assembly. The manual valve and solenoid valve are integrated into the same air distribution system, allowing both flushing modes to operate through a unified mechanical and electronic architecture rather than separate independent devices.
Solution Approach 2:
The control unit serves multiple functions: it processes signals from both manual input (button press) and sensory input (infrared sensor), controls both the solenoid valve and manual valve actuation, and manages the air pump operation. This multi-functionality reduces the need for separate control systems for manual and sensory flushing, simplifying the overall device construction.
3Adaptability or versatility
If manual and sensory flushing solutions are combined using two complete independent devices, then both flushing modes are available, but manufacturing costs increase
Solution Approach 1:
The patent merges manual and sensory flushing systems into a single integrated device by sharing common components including the air pump, air bags, control unit, and valve assembly.
