Biometric Bed Access Control for Personalized Feature Settings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current beds with electronically-controllable features lack effective user authentication and access control, leading to potential misuse of features by unauthorized personnel, and do not adequately adjust settings based on user identity or health conditions.
Innovation Solution
A bed system incorporating biometric sensors and non-biometric input devices, with a controller that analyzes user inputs to enable or disable features and modify settings based on user identity, health conditions, and healthcare information system data, ensuring secure access and personalized feature configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If biometric sensors are added to identify users and control access to bed features, then security and personalized configuration are improved, but device complexity increases
Solution Approach 1:
A controller serves as an intermediary between biometric sensors, non-biometric input devices, and bed features. The controller receives biometric data, identifies users, determines access permissions, and selectively enables or disables bed features based on user identity, thereby managing system complexity centrally while improving security
2Reliability
If access to bed features is restricted based on user identity, then patient safety is improved, but ease of operation deteriorates
Solution Approach 1:
The system dynamically adjusts access permissions and bed feature availability based on real-time user identification through biometric sensors. Different user types (patients, caregivers, visitors) receive different levels of access, with the system automatically adapting its behavior without requiring manual configuration changes
3Reliability
If biometric authentication is required before activating bed features, then unauthorized misuse is prevented, but time consumption increases
Solution Approach 1:
The system performs biometric authentication in advance before enabling access to bed features. Users must provide biometric data and receive authorization prior to operating any controlled features, ensuring that security checks are completed proactively rather than reactively
Data Source
AI summary
A bed has one or more electronically-controllable features. Input-output devices are used by persons to control the electronically-controllable features. A biometric input-output device obtains biometric data from persons who desire to control one or more of the electronically-controllable features. The bed may restrict access to or modify one or more of the electronically-controllable features based on the biometric data.
