Solution Overview

Problem

Existing bidet apparatuses lack an effective drying mechanism for the nozzle outlet, leading to prolonged drying times and compromised sanitary conditions due to moisture retention, which can result in odor and bacterial growth.

Innovation Solution

A bidet apparatus equipped with a drying device that includes an air blower, a drying duct, and a branch duct to direct air flow to the nozzle outlet, facilitating quick and efficient drying through a movable and adjustable air dispensing system.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If natural drying is used without a separate drying operation, then device complexity is reduced, but drying time increases and sanitary conditions deteriorate

Engineering Contradiction:
Improvedrying device structureVSAvoiddrying time
Core Design Contradiction:
Device complexityVSLoss of time

Solution Approach 1:

The patent applies pneumatic principles by using an air blower to generate airflow that passes through the drying duct and exits through the nozzle discharge outlet. This pneumatic drying mechanism efficiently removes moisture from the nozzle outlet without requiring complex mechanical moving parts, thus reducing device complexity while significantly decreasing drying time and improving sanitary conditions

Inventive Principle:
Principle #29Pneumatics and hydraulics

2Ease of manufacture

If natural drying is used without a separate drying operation, then manufacturing cost is reduced, but sanitary conditions deteriorate due to moisture retention

Engineering Contradiction:
Improvemanufacturing costVSAvoidbacterial growth and odor
Core Design Contradiction:
Ease of manufactureVSObject-affected harmful factors

Solution Approach 1:

The air blower and drying duct system provides an effective drying mechanism that prevents moisture accumulation on the nozzle outlet. By using airflow to evaporate and remove water, the system prevents bacterial growth and odor formation without requiring complex mechanical structures, making it easy to manufacture while significantly improving sanitary conditions

Inventive Principle:
Principle #29Pneumatics and hydraulics
