Solution Overview
Problem
Existing foam discharge devices suffer from complicated manual operation, excessive foam discharge, and unnecessary consumption of foam agents due to manual switching between water and foam modes.
Innovation Solution
A water discharge device with an electrical switcher and control circuit unit that automatically switches from a foam discharge state to a water discharge state after a predetermined time, preventing excessive foam discharge and agent consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If manual switching mechanism is used to switch between water and foam discharge, then the device can change discharge modes, but the operation becomes complicated and excessive foam accumulates in the drain outlet
Solution Approach 1:
The patent replaces the manual mechanical switching mechanism with an automated control system. The control unit automatically switches between water discharge and foam discharge modes based on detected conditions, eliminating the need for manual operation and preventing excessive foam accumulation through automated control.
2Adaptability or versatility
If manual switching mechanism is used to switch between water and foam discharge, then the device can change discharge modes, but excessive foam accumulates in the drain outlet
Solution Approach 1:
The patent implements a feedback control mechanism where the control unit monitors discharge conditions and automatically adjusts the switching between water and foam discharge modes. This feedback system prevents excessive foam accumulation by detecting when foam discharge should be terminated and automatically switching to water discharge mode.
3Adaptability or versatility
If manual switching mechanism is used to switch between water and foam discharge, then the device can change discharge modes, but excessive foam agent is used
Solution Approach 1:
The patent enables the system to automatically manage its own operation through the control unit, which autonomously switches between discharge modes based on detected conditions. This self-service mechanism ensures foam agent is used only when necessary and prevents waste through automated termination of foam discharge.
4Loss of substance
If automated control is implemented to prevent excessive foam discharge, then foam agent consumption is reduced, but device complexity increases
Solution Approach 1:
The patent replaces complex manual mechanical switching mechanisms with an automated electronic control system. While this introduces electronic components, it eliminates the need for manual operation and provides precise control over foam discharge timing, ultimately reducing overall system complexity in terms of operation and maintenance.

AI summary
A water discharge device 1 includes a switcher 3 and a control circuit unit 8. The switcher 3 switches between a first discharge state of discharging supplied water and a second discharge state of discharging a fluid obtained by mixing an additive into supplied water, through electrical operation. The control circuit unit 8 controls switching by the switcher 3 based on operation input from a user. When the second discharge state has been selected by operation input and when a certain time has elapsed from the start of discharge in the second discharge state, the control circuit unit 8 switches the operating state to the first discharge state.
