Solution Overview

Problem

Existing shower toilets face challenges such as complex structures, dirt-prone joints, and difficulties in cleaning due to separate technology components, as well as space constraints and inadequate rinsing in integrated designs, leading to a need for a more compact and easy-to-clean solution.

Innovation Solution

A novel combination component that integrates the shower toilet lance housing with the flushing water distributor, mounted between the toilet body and flush pipe connector, with an enlarged diameter to accommodate the lance at an angle, allowing for optimal positioning and easy installation, eliminating the need for separate technology blocks and reducing the number of seals.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If separate technology blocks are used for shower toilet attachment, then adaptability to different toilet bodies is improved, but device complexity and number of joints increase

Engineering Contradiction:
Improveadaptability to different toilet bodiesVSAvoiddevice complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent combines the shower toilet technology block with the flushing water distributor into a single integrated component. The shower lance housing is formed as one piece with the flushing water distributor, eliminating separate attachment devices and reducing the number of joints while maintaining adaptability through the standardized flushing connection.

Inventive Principle:
Principle #5Merging (Combining)

2Ease of manufacture

If separate technology blocks are used for shower toilet attachment, then ease of manufacture is improved, but ease of cleaning deteriorates due to dirt-prone joints

Engineering Contradiction:
Improveease of manufactureVSAvoidease of cleaning
Core Design Contradiction:
Ease of manufactureVSEase of operation

Solution Approach 1:

The integrated design merges the shower lance housing with the flushing water distributor into a single component that can be manufactured as one piece. This eliminates the joints and edges between separate components that trap dirt, making the toilet easier to clean while maintaining manufacturing simplicity through standardized flushing connections.

Inventive Principle:
Principle #5Merging (Combining)

3Device complexity

If shower lance is integrated into flushing water distributor, then device complexity is reduced, but space for lance accommodation becomes constrained

Engineering Contradiction:
Improvedevice complexityVSAvoidspace for lance accommodation
Core Design Contradiction:
Device complexityVSVolume of moving object

Solution Approach 1:

The shower lance is nested within the flushing water distributor housing. The lance housing is formed as one piece with the distributor, with the lance positioned inside the distributor's structure. This nested arrangement reduces overall device complexity while providing adequate space for the lance to extend and retract without requiring additional external components.

Inventive Principle:
Principle #7Nested doll (Nesting)

4Adaptability or versatility

If standard flushing pipe connector diameter is used, then adaptability to standard installations is improved, but ability to accommodate shower lance deteriorates

Engineering Contradiction:
Improveadaptability to standard installationsVSAvoidability to accommodate shower lance
Core Design Contradiction:
Adaptability or versatilityVSVolume of moving object

Solution Approach 1:

The patent merges the shower lance housing with the flushing water distributor, allowing the combined component to connect to standard flushing pipes while internally accommodating the shower lance. The integration enables the system to maintain standard external connection dimensions while providing sufficient internal space for the lance mechanism through optimized spatial arrangement.

Inventive Principle:
Principle #5Merging (Combining)
