Restroom Fixture Navigation With Audio and Tactile Occupancy Cues
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Individuals with vision impairments face challenges navigating public places, particularly restroom facilities, due to varying layouts and the difficulty in locating unoccupied fixtures like toilets, sinks, and soap dispensers, which can prevent them from accessing public spaces.
Innovation Solution
A navigation system that provides audio or tactile feedback to users through connected fixtures, using sensors and communication devices like smartphones or canes, to help locate and determine the occupancy status of fixtures, allowing for independent navigation without assistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If public restroom facilities are designed with various layouts and fixtures, then the functionality and versatility of the restroom is improved, but the difficulty for vision-impaired individuals to locate fixtures and navigate the space increases
Solution Approach 1:
The patent introduces audio signals and tactile feedback devices as intermediaries between the restroom fixtures and vision-impaired users. These mediators provide location and occupancy information without requiring visual contact with the fixtures, thus resolving the contradiction between maintaining diverse restroom layouts and improving accessibility for vision-impaired individuals.
Solution Approach 2:
The patent replaces the visual-mechanical navigation system with an acoustic and tactile information system. Instead of relying on visual cues from fixture placement and design, the system uses audio signals emitted by fixtures and tactile feedback from canes or handheld devices to guide users, thereby maintaining restroom versatility while eliminating navigation difficulties.
2Adaptability or versatility
If vision-impaired individuals use public restroom facilities, then accessibility is improved, but the risk of encountering occupied fixtures or obstacles increases
Solution Approach 1:
The patent implements a feedback system where fixtures actively communicate their occupancy status to users through audio signals. When a user approaches or requests information about a fixture, the system provides real-time feedback about whether the fixture is occupied or available, enabling vision-impaired individuals to make informed decisions and reducing the risk of encountering occupied fixtures.
3Device complexity
If traditional restroom navigation methods are used, then the system complexity is minimized, but the ability to provide location and occupancy information to vision-impaired users is insufficient
Solution Approach 1:
The patent enables fixtures to provide their own location and occupancy information autonomously through integrated sensors and audio output devices. Each fixture independently detects its occupancy status and communicates this information to users, eliminating the need for complex centralized monitoring systems while ensuring complete information availability for vision-impaired users.
