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 officers may not carry devices, leading to incomplete event documentation, and devices without networking capabilities cannot inform remote servers in real-time.
Innovation Solution
A method for wirelessly starting information-capturing devices using near-field communication technology, which receives event messages, compares identification codes, and initiates data capture or broadcasts messages to neighboring devices capable of remote communication, ensuring automatic recording and remote event reporting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If manual starting of information-capturing device is used, then device operation control is simple, but response time in emergency situations is too late
Solution Approach 1:
The information-capturing device automatically starts itself when an event is detected through the event detection module, eliminating the need for manual operation. The device monitors its own state and autonomously initiates data capture when predefined event conditions are met, resolving the contradiction between rapid response and operational simplicity.
Solution Approach 2:
The device performs preliminary monitoring of event conditions through the event detection module before actual data capture is needed. By continuously detecting events and pre-positioning the capture system, the device ensures immediate response when an event occurs, reducing response time while maintaining automated operation.
2Quantity of substance
If single information-capturing device is carried, then device portability is maintained, but multi-angle coverage of event is insufficient
Solution Approach 1:
Multiple information-capturing devices are merged into a coordinated network where each device captures data from its own location and angle. The results are combined and transmitted to the server, achieving comprehensive multi-angle coverage while maintaining the portability of individual devices. Each device remains lightweight but contributes to collective versatility.
Solution Approach 2:
The system enables each portable device to serve multiple functions: local event detection, data capture, and network communication. By making each device universally capable of these functions, the system maximizes the utility of individual units while achieving comprehensive coverage through their coordinated operation.
3Loss of time
If non-networking information-capturing device is used, then device simplicity is maintained, but real-time remote reporting is impossible
Solution Approach 1:
A server acts as an intermediary between the information-capturing devices and the final destination. The server receives data from devices, processes it, and distributes it to appropriate recipients. This intermediary approach enables real-time reporting without requiring each device to have complex direct network connections, maintaining device simplicity while achieving rapid remote reporting.
Solution Approach 2:
The system adds a dimensional layer by introducing centralized server processing. Instead of devices directly connecting to multiple destinations, data flows through an intermediate server dimension, enabling scalable and efficient distribution. This dimensional change allows simple devices to achieve complex reporting capabilities through the server intermediary.
4Speed
If automatic starting based on event detection is implemented, then response speed is improved, but false triggering may occur
Solution Approach 1:
The system incorporates feedback mechanisms where the event detection module continuously monitors conditions and adjusts its triggers based on confirmed event patterns. By receiving feedback about actual event occurrence and comparing it with detected signals, the system reduces false triggers while maintaining rapid response to genuine events through iterative verification.

Data Source
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.
