Solution Overview

Problem

Existing sanitary cubicle facilities face a trade-off between compact design for easy transport and sufficient user space, with no previous solution effectively balancing these opposing objectives for comfortable use.

Innovation Solution

A sanitary cubicle facility with a frame and internal unit that can be compactly arranged for transport, where the internal unit is largely or completely pushed into the frame, and then laterally pulled out to increase the floor area, allowing for comfortable use while maintaining a compact transport form.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Length of moving object

If the sanitary cubicle installation is designed compactly for transport, then ease of transport is improved, but the floor area and user space are reduced

Engineering Contradiction:
Improvetransport dimensionVSAvoidfloor area
Core Design Contradiction:
Length of moving objectVSArea of stationary object

Solution Approach 1:

The inner unit is designed to be movable between a retracted position during transport and an extended position during operation. This dynamic configuration allows the same structure to provide compact dimensions for transport while offering sufficient floor area when deployed, directly resolving the contradiction between transport compactness and user space

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The inner unit containing sanitary fixtures is nested within the frame structure during transport, similar to a nested doll configuration. This allows the movable inner unit to be compactly stored within the outer frame, achieving small transport dimensions while enabling expansion to provide adequate user space when the inner unit is extended outward during operation

Inventive Principle:
Principle #7Nested doll (Nesting)

2Productivity

If multiple sanitary cubicles are arranged in a compact installation, then transport efficiency is improved, but the space for each user is reduced

Engineering Contradiction:
Improvetransport efficiencyVSAvoiduser comfort
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

Each sanitary cubicle incorporates a movable inner unit that can be extended to provide sufficient user space during operation. This dynamic extension capability ensures that even when multiple cubicles are arranged compactly for efficient transport, each individual cubicle can expand to accommodate comfortable user conditions when deployed

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The installation is segmented into multiple independent cubicle units, each with its own movable inner unit containing sanitary fixtures. This segmentation allows each cubicle to independently expand to provide adequate user space while the overall installation maintains compact dimensions for efficient transport when all inner units are retracted

Inventive Principle:
Principle #1Segmentation

AI summary

Sanitary cubicle installation comprising at least one sanitary cubicle, wherein at least one sanitary fixture is arranged within the sanitary cubicle. A frame is provided, comprising at least a frame ceiling, a frame floor, and two frame side walls. Furthermore, an inner unit is provided, comprising at least a ceiling section, a floor section, and two side walls. In a transport state, the inner unit is at least largely retracted into the frame. In an operational state, the inner unit is at least partially extended laterally out of the frame.
