Solution Overview
Problem
Existing data management systems for body worn cameras are vulnerable to network failures, require expensive and replaceable docking stations, and lack flexibility in supporting multiple data management systems.
Innovation Solution
A system comprising a body worn camera, a docking station with minimal intelligence, and a separate recorder for intermediate data storage, allowing secure and flexible data transfer to a data management system over a local area network.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If continuous wireless transfer is used, then data transfer convenience is improved, but system reliability deteriorates due to network connection failures
Solution Approach 1:
The docking station serves as an intermediary device between the body worn camera and the data management system. It provides a reliable wired connection for data transfer, eliminating the unreliability of wireless networks while maintaining ease of operation through automatic data transfer when the camera is docked.
Solution Approach 2:
The docking station includes local storage capacity to buffer data temporarily. If the network connection to the data management system fails, the data is safely stored in the docking station's storage, preventing data loss and ensuring reliability while maintaining the convenience of automatic transfer.
2Reliability
If docking station with integrated storage is used, then data security is improved, but system cost deteriorates due to expensive and replaceable components
Solution Approach 1:
The system is segmented into separate functional components: the body worn camera, the docking station with minimal intelligence and basic storage, and the central data management system with primary storage. This segmentation allows each component to be optimized independently, reducing overall system cost while maintaining data security through the distributed architecture.
3Reliability
If docking station is made robust for secure storage, then data security is improved, but device complexity and replacement cost deteriorates
Solution Approach 1:
The docking station is designed as a simple intermediary with minimal intelligence, performing only basic functions: receiving the camera, transferring data via wired connection, and providing temporary buffering storage. The complex security and data management functions are relocated to the central data management system, reducing docking station complexity and replacement cost while maintaining overall data security.
4Quantity of substance
If local storage capacity of camera is increased, then data retention is improved, but data transfer security deteriorates due to overwrite risk before transfer
Solution Approach 1:
The docking station provides a buffer storage area that temporarily holds data from the camera before it is transferred to the central data management system. This cushioning storage prevents data overwrite by ensuring that incoming data is safely buffered until successful transfer, thereby maintaining data transfer security even when camera storage capacity is limited.
