Solution Overview

Problem

Existing shower systems waste thermal energy in the form of steam, which is not effectively captured to heat incoming water, leading to inefficiency and potential damage to bathroom fixtures and décor.

Innovation Solution

A shower steam condenser panel is integrated into the shower system to condense steam and transfer thermal energy to incoming water, enhancing user experience and efficiency by making the system visible and decorative.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of energy

If conventional shower systems are used, then incoming cold water is heated by external energy sources, but thermal energy from steam is wasted and not captured

Engineering Contradiction:
Improvethermal energy from steamVSAvoidenergy consumption for heating water
Core Design Contradiction:
Loss of energyVSUse of energy by moving object

Solution Approach 1:

The patent converts the harmful waste steam into a beneficial heat source by capturing it through condensation surfaces and using the released latent heat to preheat incoming cold water through heat exchange channels, thereby eliminating energy loss and reducing external heating requirements

Inventive Principle:
Principle #22Blessing in disguise (Convert harm into benefit)

Solution Approach 2:

The patent utilizes the phase transition of steam condensing into liquid water on the condensation surfaces, which releases latent heat that is then transferred through the panel structure to heat the incoming cold water flowing through internal channels

Inventive Principle:
Principle #36Phase transitions

2Loss of energy

If a shower steam condenser panel is integrated into the shower environment, then thermal energy from steam is captured to heat incoming water, but the device complexity increases

Engineering Contradiction:
Improvethermal energy captureVSAvoidpanel structure with flow channels
Core Design Contradiction:
Loss of energyVSDevice complexity

Solution Approach 1:

The patent merges the steam condensation function with the water heating function into a single integrated panel structure, where the condensation surfaces and heat exchange channels are combined in one component, eliminating the need for separate condensation and heating systems

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The panel structure serves multiple functions simultaneously: it acts as a condensation surface for steam, provides heat exchange channels for water heating, and functions as a structural element within the shower environment, thereby reducing overall system complexity despite the added functionality

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