Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In emergency situations, information-capturing devices are often started too late, capturing media data from a single angle, and some devices lack networking capabilities to inform remote servers promptly.
Innovation Solution
An event detecting and recording system that uses state sensors to generate event messages, triggering near-field communication to start video recording devices and send reports to a server via a remote communication module, ensuring automatic and multi-angle data capture and remote notification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If users manually start information-capturing devices, then the devices can capture media data, but in emergency situations it is too late to start the devices by hand and crucial images and sounds cannot be captured
Solution Approach 1:
The system performs preliminary actions by continuously monitoring the environment through state sensors and maintaining readiness to capture media data. The information-capturing device is pre-configured with event triggers and can immediately begin recording when predefined conditions are detected, eliminating the need for manual activation during emergencies.
Solution Approach 2:
The system enables self-service by allowing the information-capturing device to automatically detect events through state sensors and initiate media capture without human intervention. The device monitors its own operational state and environmental conditions, then autonomously starts recording when emergency conditions are detected.
2Ease of operation
If each police officer carries one information-capturing device, then the device can be operated manually, but media data are captured from a single angle rather than multiple angles
Solution Approach 1:
The system merges multiple information-capturing devices into a coordinated network where each device contributes to comprehensive event documentation. Multiple devices capture media data from different locations and angles, and the system combines these perspectives to provide complete multi-angle coverage of the emergency event.
Solution Approach 2:
The system provides multi-functionality by enabling information-capturing devices to serve both as individual manually-operated units and as part of a coordinated automatic capture network. Each device maintains its manual operation capability while also being capable of automatic activation and coordination with other devices for comprehensive coverage.
3Adaptability or versatility
If some police officers do not carry information-capturing devices, then they can operate without equipment constraints, but they cannot capture media data while on duty
Solution Approach 1:
The system uses state sensors and communication networks as intermediaries to enable data capture capability. Even officers without personal information-capturing devices can contribute to event documentation through wearable state sensors that detect emergency conditions and trigger nearby devices, or through networked communication that coordinates device activation across the team.
4Device complexity
If information-capturing devices are not capable of networking, then the device structure is simpler, but they cannot inform a remote server of an event as soon as it occurs
Solution Approach 1:
The system performs preliminary actions by pre-configuring communication protocols and server connection parameters in the information-capturing devices. When events occur, the devices can immediately transmit data to remote servers without requiring complex real-time networking setup, achieving fast notification through advance preparation.
Solution Approach 2:
The system replaces complex mechanical networking infrastructure with wireless communication and network protocols. Instead of requiring physical network connections and complex routing infrastructure, the devices use wireless transmission to communicate event data to remote servers, simplifying the physical system while maintaining communication speed.

AI summary
A method of starting an information-capturing device includes: receiving an event message including a destination information by a near-field communication technology, comparing a first identification code of the information-capturing device with the dedicated identification code specified by the destination information contained in the event message, starting the information-capturing device to capture ambient data if the first identification code matches the dedicated identification code specified by the destination information contained in the event message, and broadcasting the event message by the near-field communication technology if the first identification code does not match the dedicated identification code specified by the destination information contained in the event message.
