Solution Overview

Problem

Existing fluid supply devices, particularly for hot water, require significant energy consumption and result in high electricity costs and environmental impact due to direct heating of cold water to high temperatures.

Innovation Solution

A system comprising a hot fluid supply device connected to a central heating system, a cold fluid supply device, and a local hot fluid supply device, with a valve assembly to mix or control fluid flow, allowing for the use of warm fluid to generate hot fluid, reducing energy demand by preheating with renewable sources.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Temperature

If cold water is heated directly to high temperatures using direct electric heating, then hot water can be provided, but energy consumption and electricity costs increase significantly

Engineering Contradiction:

Improvewater temperatureVSAvoidenergy consumption

Core Design Contradiction:

TemperatureVSUse of energy by moving object

Solution Approach 1:

The system performs preliminary heating of water using warm water from the central heating system before final heating to hot temperature. This preheating action reduces the energy required for the subsequent heating step, directly addressing the energy consumption problem while achieving the desired high temperature output

Inventive Principle:

Principle #10Preliminary action

2Adaptability or versatility

If a local hot fluid supply device is added to provide hot fluid, then hot fluid can be supplied without relying solely on central heating, but device complexity increases

Engineering Contradiction:

Improvehot fluid supply capabilityVSAvoidsystem complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system merges the central heating system's warm water supply with a local hot fluid supply device. The warm water line from the central heating system is integrated with the local heater, allowing the same infrastructure to serve dual purposes: distributing warm water centrally and providing hot water locally when needed, thereby increasing adaptability without proportionally increasing complexity

Inventive Principle:

Principle #5Merging (Combining)
