Solution Overview

Problem

Existing faucets often fail to immediately discharge water at the desired temperature due to inconsistent hot water supply, leading to user inconvenience and potential safety issues.

Innovation Solution

A jog dial type operation switch with an upper assembly, lower assembly, and wheel assembly that allows for natural drainage of water and enables selection and operation of various control target devices using a single switch, while also incorporating a lamp system to indicate operation states and improve aesthetic appeal.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a conventional faucet is used to control water temperature, then the user can adjust the water temperature by rotating a control lever, but the hot water in the hot water pipe cools down after a predetermined period of time, causing the user to flow water down without using the cooled water, which results in waste of water

Engineering Contradiction:
Improvewater temperature consistencyVSAvoidwater waste
Core Design Contradiction:
ReliabilityVSLoss of substance

Solution Approach 1:

The system pre-heats water in the storage tank before it is needed, and the control system activates the water heater in advance based on predicted usage patterns. This ensures hot water is ready immediately when the user opens the faucet, eliminating the need to flush cooled water from the pipes and preventing water waste.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system incorporates temperature sensors that continuously monitor the temperature of water in the storage tank and in the distribution pipes. This feedback information is used by the control system to activate the water heater when temperatures drop below the desired threshold, maintaining consistent hot water supply and preventing water waste from flushing cooled water.

Inventive Principle:
Principle #23Feedback

2Ease of operation

If the user adjusts the temperature by rotating the control lever directly, then the user can control water temperature, but the user may get burnt when the lever is suddenly operated

Engineering Contradiction:
Improvetemperature controlVSAvoidburn risk
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The system introduces a control system with temperature sensors and a water heater as intermediaries between the user and the hot water supply. The control system monitors water temperature continuously and activates the water heater in advance to maintain the desired temperature, eliminating sudden temperature changes that could cause burns while preserving easy temperature control through the existing lever mechanism.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The control system performs preliminary heating actions by activating the water heater before the user opens the faucet. This pre-heating ensures that the water temperature is already at the desired level when the user operates the lever, preventing sudden temperature changes that could cause burns while maintaining ease of operation.

Inventive Principle:
Principle #10Preliminary action

3Adaptability or versatility

If various types of convenience apparatuses and bathroom furniture are provided separately, then each component can function independently, but the bathroom furniture and convenience apparatuses are considered as separate components requiring multiple power outlets and storage locations

Engineering Contradiction:
Improvecomponent independenceVSAvoidnumber of components
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent combines multiple previously separate components into an integrated bathroom furniture system. The water heater, storage tank, control system with temperature sensors, and bathroom furniture are merged into a single unified system, reducing the number of separate components and power outlets needed while maintaining the independence and functionality of each subsystem.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The integrated bathroom furniture system performs multiple functions within a single unit: it provides storage space, houses the water heater and storage tank, contains the control system with temperature monitoring, and supplies hot water to the faucet. This multi-functionality reduces device complexity while maintaining the adaptability and independence of each functional component.

Inventive Principle:
Principle #6Universality (Multi-functionality)
