Physical Notification Devices for Service Delivery in Poor Reception
Solution Overview
Problem
Current location-based services face challenges in delivering physical services effectively, especially in areas with poor cell-phone reception, such as large buildings, and require a system to handle both automatic and manual service delivery requests in real-time.
Innovation Solution
A system comprising user-end electronic devices, service notification processors, and physical notification devices that use various communication protocols to facilitate service delivery requests, including sensors and transducers, allowing for precise location-based service notifications and delivery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If location-based services use cell-phone reception for service delivery notifications, then service delivery can be requested and tracked, but service delivery fails in areas with poor cell-phone reception such as large buildings
Solution Approach 1:
The patent introduces physical notification devices (banners, signs, displays) as intermediaries between the service request system and the end user. These devices are placed at physical locations within large buildings and receive notifications from the service notification processor, then display them locally without requiring cell-phone reception. This mediator approach bypasses the harmful effect of poor cellular coverage while maintaining reliable service delivery notification.
Solution Approach 2:
The system segments the notification delivery function into two parts: digital notification processing (handled by the service notification processor) and physical notification display (handled by distributed physical notification devices at various locations). This segmentation allows the notification system to operate independently of cellular reception by placing intelligent notification devices throughout the building infrastructure.
2Adaptability or versatility
If the system uses multiple communication protocols and physical notification devices, then service delivery can be achieved in areas with limited connectivity, but the device complexity increases
Solution Approach 1:
The service notification processor is designed to handle multiple communication protocols (Bluetooth, Wi-Fi, cellular, wired LAN) and can operate in different modes (automatic sensor-triggered or manual user-requested). Physical notification devices serve multiple functions including displaying service requests, providing location information, and confirming service delivery. This multi-functionality reduces the need for separate specialized devices for each function.
Solution Approach 2:
The system incorporates automatic sensor detection capabilities (pressure sensors, proximity sensors, location sensors) that can automatically trigger service delivery requests without human intervention. The physical notification devices autonomously receive and display notifications based on their local state changes, reducing the need for complex centralized control and simplifying the overall system architecture.
3Productivity
If manual or automatic service delivery requests are processed in near real-time, then service delivery efficiency improves, but the system requires complex processing and notification mechanisms
Solution Approach 1:
Physical notification devices are pre-deployed throughout the building at locations where services may be needed. These devices are ready to immediately display notifications when service requests are generated, eliminating the need for real-time communication back to a central server for each notification. The service notification processor maintains a ready state to quickly process and forward requests to the appropriate physical devices.
Solution Approach 2:
The system replaces complex real-time communication mechanisms with simpler local display mechanisms. Instead of requiring continuous bidirectional communication between the service notification processor and user devices in areas with poor reception, the system uses one-way notification display at physical locations, which is inherently simpler and more reliable in limited connectivity environments.
