Solution Overview

Problem

Conventional toilet design and manufacturing processes require significant time and effort to re-engineer the flush engine for new designs, leading to varying performance characteristics and inefficiencies, particularly in terms of energy consumption.

Innovation Solution

A modular toilet design featuring interchangeable panels and a robotic manufacturing process that allows for quick assembly and customization of toilet components, such as the flush engine, bowl, and seat, using sensors and automated assembly to streamline production and reduce engineering time.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional toilet design processes are used where the entire flush engine is re-engineered for new designs, then design flexibility and customization are improved, but development time and engineering effort increase significantly

Engineering Contradiction:
Improvedesign flexibilityVSAvoiddevelopment time
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The flush engine is divided into separate modular components (bowl, sump, trapway) that can be independently designed, manufactured, and validated. This segmentation allows new toilet designs to be created by combining existing validated modules rather than re-engineering the entire system, thus reducing development time while maintaining design flexibility.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The modular components are designed with standardized interfaces and connection points that allow them to be universally applied across different toilet designs. The trapway module, for example, can be used with different bowl and sump configurations, enabling multiple aesthetic designs to share common performance-critical components that have already been validated.

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

2Adaptability or versatility

If conventional toilet design processes are used where the entire flush engine is re-engineered for new designs, then design flexibility is improved, but engineering effort and cost increase

Engineering Contradiction:
Improvedesign flexibilityVSAvoidengineering effort
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The flush engine is divided into separate modular components (bowl, sump, trapway) that can be independently designed, manufactured, and validated. This segmentation allows new toilet designs to be created by combining existing validated modules rather than re-engineering the entire system, thus reducing development time while maintaining design flexibility.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Critical performance components such as the trapway are pre-designed, pre-tested, and pre-validated as standalone modules before being integrated into new toilet designs. This preliminary action ensures that performance characteristics are already established and documented, eliminating the need for redundant engineering and validation efforts for each new design.

Inventive Principle:
Principle #10Preliminary action

3Strength

If conventional firing processes are used for porcelain toilets, then structural integrity is achieved, but energy consumption is high

Engineering Contradiction:
Improvestructural integrityVSAvoidenergy consumption
Core Design Contradiction:
StrengthVSUse of energy by moving object

Solution Approach 1:

The material state is changed from traditional porcelain requiring high-temperature firing to thermoplastic materials that can be formed at lower temperatures. The trapway module is manufactured using injection molding or similar processes that achieve the necessary structural integrity without the energy-intensive firing process, thereby reducing energy consumption while maintaining strength.

Inventive Principle:
Principle #35Parameter changes
