Solution Overview

Problem

Conventional embedded thermostatic fittings require large trim plates to conceal masonry openings and have limited accessibility for maintenance or repair due to their integrated design.

Innovation Solution

A modular thermostatic fitting comprising separate intake, mixing, and distribution modules connected via piping sectors, housed in a container that acts as packaging, allowing for reduced masonry openings and easy embedding, with separate check valves and filters for improved maintenance access.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If conventional integrated thermostatic fittings are used, then all tap elements are contained in a single casing, but the masonry opening must be concealed by large trim plates

Engineering Contradiction:
Improveintegrated designVSAvoidmasonry opening
Core Design Contradiction:
Device complexityVSArea of stationary object

Solution Approach 1:

The thermostatic fitting is divided into separate modules (intake module, mixing module, distribution module) that can be installed independently, eliminating the need for a single large integrated casing and reducing the required masonry opening area

Inventive Principle:
Principle #1Segmentation

2Device complexity

If conventional integrated thermostatic fittings are used, then all components are housed in one casing, but accessibility for maintenance or repair is limited

Engineering Contradiction:
Improveintegrated designVSAvoidaccessibility
Core Design Contradiction:
Device complexityVSEase of repair

Solution Approach 1:

By separating the fitting into modular components, each module can be independently accessed, removed, and maintained, significantly improving accessibility for repair and cleaning operations compared to integrated designs where all components are enclosed in a single casing

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The check valves and filters are extracted as separate accessible components that can be independently removed and maintained without disassembling the entire fitting, enabling easy cleaning and replacement

Inventive Principle:
Principle #2Taking out (Extraction)

3Ease of repair

If modular design is used, then accessibility for maintenance is improved, but the number of separate components increases

Engineering Contradiction:
ImproveaccessibilityVSAvoidnumber of modules
Core Design Contradiction:
Ease of repairVSDevice complexity

Solution Approach 1:

Each module is designed with multi-functionality, performing multiple operations within compact dimensions, which offsets the increase in component count by reducing the overall spatial footprint and installation complexity

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

AI summary

The present invention refers to a thermostatic fitting for bath/shower that comprises three separate modules, intake module (5), mixing module (6) and distribution module (7), connected to each other via piping sectors, the said thermostatic fitting being housed in a container (8) that acts as packaging, allowing embedded wall mounting, in a horizontal or vertical position, this mode of packaging being another construction element, so that once the container (8) is embedded, the thermostatic fitting easily remains flush and level with the wall, making it possible, given that the modules are separate, for the front of the container (8) to be tiled, with a decorative covering in between the modules, providing a very different aesthetic and practical option, the different intake (5), mixing (6) and distribution (7) modules remaining concealed by means of the insertion of the corresponding caps and knobs.
