Solution Overview

Problem

The challenge lies in mounting a water closet with an integrated douche device and toilet seat set in a way that maintains an attractive visual appearance while ensuring stability and hiding cables and water lines.

Innovation Solution

A mounting plate with detachable fastening elements is used to secure both the douche device housing and the toilet seat set to the toilet bowl, allowing for easy installation and alignment, with fastening elements that can be screwed or latched into place, and incorporating washers and projections for secure engagement, ensuring cables and hoses are concealed.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If the douche device housing and toilet seat set are directly mounted on the toilet bowl, then the mounting is simple, but the appearance is compromised due to visible cables and water lines

Engineering Contradiction:
Improvemounting simplicityVSAvoidvisual appearance
Core Design Contradiction:
Ease of manufactureVSShape

Solution Approach 1:

A mounting plate is introduced as an intermediary component between the toilet bowl and the devices to be mounted. This plate provides a clean mounting surface that conceals cables and water lines, thereby resolving the contradiction between simple mounting and attractive appearance by adding a mediating element that handles the aesthetic requirement while maintaining mounting simplicity.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If multiple separate fastening elements are used for douche device and toilet seat, then each component can be securely fastened, but the device complexity increases

Engineering Contradiction:
Improvemounting stabilityVSAvoidfastening system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The mounting plate is designed with multiple fastening elements that serve dual purposes - securing both the douche device housing and the toilet seat set to the toilet bowl. This multi-functional approach allows a single component (the mounting plate) to perform multiple fastening functions, thereby reducing overall system complexity while maintaining secure mounting of all components.

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

3Stability of the object's composition

If the mounting plate is permanently fixed to the toilet bowl, then the mounting is very stable, but the installation and maintenance becomes difficult

Engineering Contradiction:
Improvemounting stabilityVSAvoidinstallation and maintenance ease
Core Design Contradiction:
Stability of the object's compositionVSEase of repair

Solution Approach 1:

The mounting plate is designed with detachable fastening elements that can be easily removed and reattached, transforming the mounting system from a permanent fixed structure to a dynamic, reversible connection. This allows the mounting plate to provide stable mounting during use while enabling easy installation, removal, and maintenance when needed, resolving the contradiction between stability and ease of repair.

Inventive Principle:
Principle #15Dynamics
