Solution Overview

Problem

Conventional toilets made entirely from porcelain or ceramic materials are difficult to maintain and repair due to their non-modular design, lacking easy access to internal components.

Innovation Solution

A toilet design featuring interchangeable or removable panels, including a cowling, front shell, side panels, and skirt, made from resin or plastic materials, allowing easy access to internal components for maintenance and repair, with features like snap fits, latching mechanisms, and flexible supports for assembly and disassembly.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If conventional toilets are made entirely from porcelain or ceramic materials, then they achieve high strength and durability, but they become difficult to maintain and repair due to non-modular design

Engineering Contradiction:
Improvestructural strengthVSAvoidmaintenance accessibility
Core Design Contradiction:
StrengthVSEase of repair

Solution Approach 1:

The toilet is divided into multiple detachable components including a removable front shell, side panels, and internal mechanisms. This segmentation allows individual parts to be accessed, removed, or replaced independently while maintaining the overall structural integrity of the porcelain body, thereby resolving the contradiction between strength and ease of repair.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The design incorporates dynamic, removable panels and shells that can be easily attached and detached from the fixed porcelain structure. This creates a hybrid system where the permanent porcelain provides strength while the removable components provide maintenance accessibility, allowing the structure to transition between closed and open states for cleaning and repair.

Inventive Principle:
Principle #15Dynamics

2Duration of action of stationary object

If conventional toilets are made entirely from porcelain or ceramic materials, then they achieve high durability, but they lack easy access to internal components for maintenance

Engineering Contradiction:
Improveservice lifeVSAvoidmaintenance convenience
Core Design Contradiction:
Duration of action of stationary objectVSEase of operation

Solution Approach 1:

The toilet structure is segmented into a permanent durable porcelain base and removable access panels. This allows the main body to maintain its long service life while the panels can be easily removed to access internal components for routine maintenance, combining durability with maintenance convenience.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The removable panel design enables users to perform basic maintenance tasks themselves without requiring professional service or disassembling the entire toilet structure. The panels are designed to be user-removable and user-replaceable, facilitating self-service maintenance while preserving the longevity of the porcelain components.

Inventive Principle:
Principle #25Self-service

3Ease of repair

If removable panels are added to provide access to internal components, then maintenance ease is improved, but device complexity increases

Engineering Contradiction:
Improvemaintenance accessibilityVSAvoidstructural complexity
Core Design Contradiction:
Ease of repairVSDevice complexity

Solution Approach 1:

The toilet is segmented into modular components with standardized connection interfaces. This segmentation provides maintenance accessibility while keeping each module relatively simple in design, preventing overall complexity from becoming unmanageable.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The removable panels and shells are designed with universal attachment mechanisms that can accommodate different internal component configurations. This multi-functionality allows the same panel design to serve multiple purposes and work with various internal arrangements, reducing the need for complex custom-designed components.

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