Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing location-based services systems require user intervention for authorization and have high energy consumption, making them complex and costly to implement with limited spatial accuracy.
Innovation Solution
A method and system utilizing non-contact detection and evaluation of media information from customer media, such as RF transceivers, to authorize and provide location-based services with minimized energy consumption, using reading devices connected to a computer for data communication and localization, featuring modes like 'sleep', 'idle', and 'active' to optimize energy use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If user intervention is required for authorization in location-based services, then security is improved, but ease of operation deteriorates
Solution Approach 1:
The customer medium automatically performs authorization by presenting its identity to the reading device without user intervention. The system self-authenticates through the unique identifier on the customer medium, eliminating the need for manual authorization actions while maintaining security through the unique identification mechanism.
Solution Approach 2:
The customer medium is pre-loaded with a unique identifier and authorization data before use. This preliminary preparation enables automatic authentication when the medium approaches the reading device, as the authorization information is already in place and requires no real-time user input.
2Measurement precision
If continuous detection and communication is performed for location-based services, then service accuracy is improved, but energy consumption deteriorates
Solution Approach 1:
The reading device performs detection at periodic intervals rather than continuously, triggering service provision when the customer medium is detected within range. This periodic detection mechanism maintains location-based service accuracy while significantly reducing energy consumption compared to continuous monitoring.
Solution Approach 2:
The system replaces continuous active communication with passive detection mechanisms. The customer medium can be detected in low-power states, and communication is established only when needed for service provision, substituting continuous energy-intensive communication with event-driven interaction.
3Reliability
If complex authorization and service provision systems are implemented, then service reliability is improved, but device complexity deteriorates
Solution Approach 1:
The authorization logic and service provision control are extracted from the customer medium and placed in the reading device or central system. The customer medium itself remains simple, containing only the unique identifier, while the complex authorization processes are handled by the reading device that detects and processes the medium's information.
Solution Approach 2:
The reading device serves as an intermediary between the simple customer medium and the service provision system. It receives the unique identifier from the medium, performs authorization checks against stored service data, and controls service activation, thereby mediating between the simple medium and complex service requirements.
4Measurement precision
If multiple reading devices are deployed for improved localization accuracy, then measurement precision is improved, but device complexity deteriorates
Solution Approach 1:
Multiple reading devices are merged into a coordinated network under central control. The central system manages the collective detection data from multiple devices to determine customer medium location and authorize services, combining their capabilities while maintaining centralized simplicity in the control logic.
Solution Approach 2:
Each reading device is designed as a universal unit capable of detecting any customer medium and communicating with the central system. This multi-functional design allows any reading device to perform the same authorization and detection functions, enabling scalable deployment without increasing individual device complexity.
