Modular Bidet Toilet Layout for Compact In-Bowl Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing shower toilets require separate and bulky components for the boiler and pump, necessitating a large casing and excessive space, with complex assembly and installation in confined spaces.
Innovation Solution
A self-contained shower toilet design where the boiler, pump, and control unit are combined into a compact block, pre-installed within the toilet bowl cavity, using simplified fastening elements for efficient space utilization and assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If separate components (boiler, pump) are used with individual casings, then each component can be independently manufactured and replaced, but the overall device occupies excessive space and requires complex assembly
Solution Approach 1:
The patent combines the boiler, pump, and control unit into a single integrated technical unit module that fits within the toilet bowl cavity. This merging eliminates the need for separate casings and reduces the total volume occupied by these components, while maintaining their individual functional independence for manufacturing and replacement purposes.
Solution Approach 2:
The technical unit module is designed to be nested within the cavity of the toilet bowl, with the boiler, pump, and control unit arranged in a compact configuration that utilizes the available space efficiently. This nesting approach allows all components to coexist in a confined space without requiring external mounting structures.
2Adaptability or versatility
If multiple separate components are installed in the toilet bowl cavity, then functional redundancy and ease of replacement are achieved, but the available installation space is insufficient
Solution Approach 1:
By merging the boiler, pump, and control unit into a single replaceable module, the patent maintains functional versatility while dramatically reducing the installation footprint. The entire technical unit module can be installed or replaced as one unit, preserving ease of maintenance while fitting within the limited cavity space.
Solution Approach 2:
The technical unit module is designed with a compact three-dimensional configuration that optimizes the use of vertical and horizontal space within the cavity. Components are arranged in layers and at different heights to maximize space utilization while maintaining accessibility for installation and maintenance.
3Ease of operation
If a separate chamber is provided for the under-shower unit, then functional separation and maintenance access are improved, but the wall thickness and overall space requirements increase
Solution Approach 1:
The patent merges the under-shower unit with the toilet bowl structure, eliminating the need for a separate chamber. The shower arm and spray elements are integrated into the bowl design, allowing maintenance access from the front while maintaining structural integrity with reduced wall thickness.
Solution Approach 2:
The under-shower unit is segmented into modular components (shower arm, spray elements, mounting mechanism) that can be independently accessed and maintained. The shower arm is designed to be extendable and removable, allowing easy maintenance without requiring thick walls or separate chambers.
