Solution Overview

Problem

Conventional bidets consume excessive power during standby mode, even when not in use, due to maintaining high temperatures set by users regardless of the toilet seat cover's state.

Innovation Solution

Incorporating a toilet seat cover sensor to detect its open or closed state and a control mechanism that adjusts the toilet seat and warm water temperatures to low settings when the bidet is not used and the power saving mode is OFF, thereby reducing energy consumption.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Temperature

If the bidet maintains high temperatures for warm water and toilet seat during standby mode, then user comfort is improved, but power consumption increases

Engineering Contradiction:
Improvetemperature of warm water and toilet seatVSAvoidpower consumption during standby mode
Core Design Contradiction:
TemperatureVSUse of energy by moving object

Solution Approach 1:

The system dynamically adjusts the temperature of warm water and toilet seat based on real-time detection of user presence and toilet seat cover state. When the toilet seat cover is closed and no user is detected, the system automatically reduces temperature to low settings, thereby reducing power consumption while maintaining user comfort when needed.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The control means continuously receives feedback from the seating sensor and toilet seat cover sensor to determine whether to maintain high or low temperature. This closed-loop feedback mechanism allows the system to automatically switch between high-temperature comfort mode and low-temperature power-saving mode based on actual usage conditions.

Inventive Principle:
Principle #23Feedback

2Reliability

If the bidet maintains high temperatures during standby mode regardless of usage, then readiness for use is improved, but energy waste increases

Engineering Contradiction:
Improvereadiness for useVSAvoidenergy waste during idle standby
Core Design Contradiction:
ReliabilityVSLoss of energy

Solution Approach 1:

The system transitions from a static high-temperature maintenance mode to a dynamic temperature control mode that adapts to usage conditions. By detecting toilet seat cover state and user presence, the system dynamically switches between ready-state heating and power-saving reduction, eliminating energy waste during idle periods while maintaining readiness when needed.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The bidet system automatically monitors its own usage state through sensors and self-adjusts temperature settings without requiring manual user input. The control means autonomously determines when to maintain high temperature for readiness and when to reduce temperature for energy saving, based on real-time sensor feedback about seat cover position and detected user presence.

Inventive Principle:
Principle #25Self-service

AI summary

Provided is a power saving device using a toilet seat cover of a bidet. The device includes: a toilet seat cover sensor for detecting whether the toilet seat cover is opened or closed and outputting an electrical signal corresponding the detected result; and a control means for controlling the toilet seat and the warm water to be at low temperatures on the basis of the detected result of the toilet seat cover sensor when a power saving mode is OFF and the bidet is not used. Therefore, it is possible to remarkably reduce power consumption of the bidet during a standby mode.
