Location Tracking Device for Automated Service Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Service recipients face challenges in verifying the presence and time spent by service providers at service locations without direct supervision, leading to uncertainty about service delivery and payment accuracy.
Innovation Solution
A system integrating a location tracking device, security device, and computer processor to authenticate service providers, track their arrival and departure, and generate service completion records, enabling secure access and autonomous payment processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If service recipients directly supervise service providers at service locations, then verification accuracy is improved, but operational complexity and time consumption increase
Solution Approach 1:
The service provider carries a location tracking device that automatically transmits location data to verify service delivery. The system self- verifies the provider's presence and service completion without requiring recipient supervision, thus maintaining high verification accuracy while reducing operational complexity.
Solution Approach 2:
The patent replaces manual supervision with an automated electronic verification system using GPS location tracking devices. The mechanical process of direct supervision is substituted with electronic data transmission and automatic verification, achieving both high accuracy and low complexity.
2Measurement precision
If service recipients are present to verify service delivery, then payment accuracy is improved, but productivity decreases due to time consumption
Solution Approach 1:
The service provider equips themselves with a location tracking device before service delivery. The device continuously transmits location data, so verification information is already available when service completion needs to be confirmed, eliminating the need for time-consuming on-site supervision while ensuring payment accuracy.
Solution Approach 2:
The location tracking device provides continuous feedback on the service provider's location and service status. This real-time feedback enables automatic verification of service delivery and triggers payment processing without requiring recipient presence, thus maintaining payment accuracy while improving productivity.
3Device complexity
If manual verification of service provider presence is used, then system complexity is reduced, but reliability of service verification deteriorates
Solution Approach 1:
The patent replaces unreliable manual verification with automated GPS location tracking. The electronic tracking system objectively records the service provider's location and service status, providing reliable verification data without adding significant system complexity, as the tracking device is carried by the provider themselves.

AI summary
A system including a location tracking device, a security device, and a computer processor and memory. The memory stores instructions that, when executed, cause the computer processor to perform the steps of obtaining a pre-determined service subscription record identifying a service provider carrying the location tracking device for performing a pre-determined service at a pre-determined location and at a pre-determined time, receiving an identifier transmitted by the location tracking device to detect an arrival of the location tracking device to the pre-determined location, obtaining, in response to detecting the arrival, a timestamp representing when the location tracking device arrives at the pre-determined location, generating, in response to detecting the arrival, a match by comparing the identifier and the timestamp to the pre-determined service subscription record, and deactivating, in response to generating the match and detecting the arrival, the security device to allow the service provider entering the pre-determined location.
