Solution Overview

Problem

Existing water heaters lack efficient heating control, often providing either too little or too much hot water due to inadequate prediction of user water consumption patterns, leading to unreasonable heating operations.

Innovation Solution

A water heater system that determines user water consumption probability for specific time periods, calculates a target water consumption amount, and adjusts operation parameters such as set temperature and heating mode to optimize hot water supply based on predicted usage, using a processor and memory to execute a heating control program that adjusts operation according to determined parameters.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If the water heater heats water to set temperature continuously, then the hot water supply is sufficient, but energy consumption increases and may provide too much hot water

Engineering Contradiction:
Improvehot water supply amountVSAvoidenergy consumption
Core Design Contradiction:
Quantity of substanceVSLoss of energy

Solution Approach 1:

The water heater performs preliminary heating actions based on predicted user water consumption patterns. The controller predicts future water usage and initiates heating before actual demand occurs, ensuring hot water is ready when needed while avoiding continuous operation. This resolves the contradiction by heating only when and how much is needed, rather than continuous heating that wastes energy.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system uses feedback from usage data and learned patterns to adjust heating operations. The controller continuously monitors actual water usage and compares it with predictions, refining its model over time. This feedback mechanism allows the system to optimize the balance between providing sufficient hot water and minimizing energy consumption based on real-world performance.

Inventive Principle:
Principle #23Feedback

2Reliability

If the water heater heats water frequently to maintain set temperature, then hot water availability is ensured, but heating control becomes unreasonable and inefficient

Engineering Contradiction:
Improvehot water availabilityVSAvoidheating control efficiency
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The system performs preliminary heating based on predicted demand patterns rather than waiting for temperature to drop and then heating frequently. By predicting when hot water will be needed and heating in advance according to learned usage patterns, the system ensures reliability while avoiding inefficient frequent heating cycles.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The heating control strategy dynamically adapts based on learned user patterns and changing conditions. The controller adjusts heating timing, duration, and intensity according to the predicted water consumption patterns that evolve over time, rather than following a fixed heating schedule. This dynamic approach improves both reliability and efficiency.

Inventive Principle:
Principle #15Dynamics

3Ease of operation

If the water heater uses simple temperature-based control, then the system is simple to operate, but it provides either too little or too much hot water without accurate prediction of user needs

Engineering Contradiction:
Improvecontrol simplicityVSAvoidwater consumption prediction accuracy
Core Design Contradiction:
Ease of operationVSMeasurement precision

Solution Approach 1:

The water heater performs self-learning of user water consumption patterns automatically without requiring user input or complex manual programming. The controller observes usage patterns over time and builds predictive models autonomously, maintaining ease of operation while achieving accurate prediction of water needs.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system uses feedback from actual usage data to continuously refine its prediction accuracy. By comparing predicted versus actual water consumption and adjusting its model accordingly, the system improves measurement precision while maintaining simple operation. The feedback loop enables the heater to learn and adapt without requiring complex user configuration.

Inventive Principle:
Principle #23Feedback
