Dynamic Wearable ID Badge with Electronic Paper Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In large facilities, traditional ID badges fail to provide up-to-date identification information and security credentials relevant to specific locations, leading to potential unauthorized access and missed important messages amidst high ambient noise levels.
Innovation Solution
A wearable ID badge system that dynamically augments visible data with real-time security information, including a conspicuous indication when an authorized security credential is exceeded, using an electronic paper display and communication network to provide timely and location-specific alerts without increasing ambient noise.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If traditional static ID badges are used, then manufacturing cost is low and simplicity is maintained, but the information is not up-to-date and cannot reflect real-time security credentials or appearance changes
Solution Approach 1:
The ID badge transitions from a static display to a dynamic electronic paper display that can update identification information, security credentials, and photos in real-time. The system dynamically adjusts the badge content based on location, security status, and received messages, ensuring information remains current without requiring manual updates.
Solution Approach 2:
The badge system serves multiple functions: displaying identification information, showing security credentials, providing location-based alerts, delivering private messages, and updating photos. This multi-functional approach consolidates several security and communication tools into a single wearable device.
2Loss of information
If broadcast messages are delivered over loudspeakers, then all personnel can receive notifications, but ambient noise level increases and important messages may be ignored or disruptive to productivity
Solution Approach 1:
Messages are delivered locally to individual badges rather than broadcasting universally through loudspeakers. Each badge receives and displays only the messages intended for that specific person, allowing message delivery without contributing to ambient noise levels or disrupting other personnel's work environments.
Solution Approach 2:
The acoustic broadcast system is replaced with an electronic display system. Instead of using loudspeakers to deliver messages acoustically, the system uses electronic paper displays on badges to present message content visually, eliminating noise while maintaining information delivery.
3Measurement precision
If real-time dynamic information is displayed on ID badges, then security monitoring accuracy is improved, but energy consumption increases
Solution Approach 1:
The display technology transitions from traditional LCD to electronic paper display, which changes the fundamental operating parameters. Electronic paper consumes power only during state changes rather than continuously during display operation, enabling real-time updates of security information while dramatically reducing overall energy consumption compared to conventional displays.
4Reliability
If location-based security alerts are provided in real-time, then unauthorized access prevention is improved, but device complexity and processing requirements increase
Solution Approach 1:
The system pre-establishes security credentials, authorized location data, and access rules in the badge and central system before situations arise. When a person enters a location, the system compares their pre-stored credentials against pre-defined security rules, enabling real-time security verification without complex processing during the actual access event.
Data Source
AI summary
A presentation of visual information relates to an accurate identity of a person. Visible data corresponding to the identity is rendered upon a wearable badge associated uniquely with the person. The rendered visible data are augmented dynamically. The augmentation includes adding a conspicuous indication to the rendered visible data, in real time, that an authorized security credential corresponding to the person is exceeded in relation to a presence of the person in a particular location.
