Double-Leaf Angled Sanitary Door for Hygiene Visibility and Privacy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Public sanitary installations, such as toilets, often lack hygiene and safety due to users not cleaning up after themselves and unclear door states, leading to unease and insecurity among users, as they cannot assess the cleanliness or occupancy of a cubicle without entering.
Innovation Solution
Implementing a double-leaf angled pivot door with a transparent glass leaf and an opaque stainless steel leaf, where the transparent leaf closes upon entry, allowing users to see the cubicle's condition and eliminating the need for an anteroom, and providing body-related operating elements for hands-free operation, along with sensors for automated functions and hygiene control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an opaque pivot door is used to close the sanitary space, then user privacy and security are improved, but the ability to assess hygiene condition and occupancy from outside deteriorates
Solution Approach 1:
The door is divided into two separate leaves: a transparent leaf for visibility and an opaque leaf for privacy. These leaves can operate independently or together, allowing the system to switch between transparent and opaque states based on occupancy, thus resolving the contradiction between security and information visibility.
Solution Approach 2:
The door system transitions from a static opaque door to a dynamic dual-leaf system where the transparent and opaque leaves can move independently. This dynamic configuration allows the door to adapt its transparency state based on whether the sanitary space is occupied, providing both visibility when empty and privacy when in use.
2Loss of information
If a transparent door is used to improve visibility of hygiene condition, then information availability is improved, but user privacy and security deteriorate
Solution Approach 1:
The door is divided into two separate leaves: a transparent leaf for visibility and an opaque leaf for privacy. These leaves can operate independently or together, allowing the system to switch between transparent and opaque states based on occupancy, thus resolving the contradiction between security and information visibility.
Solution Approach 2:
The door system transitions from a static opaque door to a dynamic dual-leaf system where the transparent and opaque leaves can move independently. This dynamic configuration allows the door to adapt its transparency state based on whether the sanitary space is occupied, providing both visibility when empty and privacy when in use.
3Ease of operation
If conventional hand-operated door handles are used, then ease of operation is improved, but germ transmission increases
Solution Approach 1:
The manual hand-operated door handle is replaced with an automated sensor-based actuation system. Sensors detect user approach and automatically open the door, eliminating the need for hand contact with door handles and significantly reducing germ transmission while maintaining ease of operation.
Solution Approach 2:
The door system provides self-service by automatically detecting user presence through sensors and opening/closing the door without requiring manual operation. This eliminates the need for users to touch door handles, reducing germ transmission while maintaining convenience.
4Loss of information
If an anteroom is added to allow assessment of hygiene condition, then information availability is improved, but device complexity and space requirements increase
Solution Approach 1:
The door is divided into two separate leaves: a transparent leaf for visibility and an opaque leaf for privacy. These leaves can operate independently or together, allowing the system to switch between transparent and opaque states based on occupancy, thus resolving the contradiction between security and information visibility.
Solution Approach 2:
The door system transitions from a static opaque door to a dynamic dual-leaf system where the transparent and opaque leaves can move independently. This dynamic configuration allows the door to adapt its transparency state based on whether the sanitary space is occupied, providing both visibility when empty and privacy when in use.

AI summary
A sanitary installation is described that comprises at least one sanitary space, which can be closed, and whose pivot door is configured as a double-leaf angled door having a leaf composed of a material that is preferably transparent over its full area and having a leaf composed of an opaque material.
