Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information-capturing devices often fail to start automatically in emergency situations, capture media data from multiple angles, and network with remote servers in a timely manner, leading to incomplete or missed evidence.
Innovation Solution
The implementation of a method that enables information-capturing devices to start wirelessly using near-field communication modules, which receive event messages to initiate video recording and broadcast data to nearby devices or remote servers, ensuring automatic data capture and reporting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If manual operation of start switch is used, then device control is simple, but response time in emergency situations is too late
Solution Approach 1:
The device automatically detects events through sensors (motion, sound, etc.) and initiates recording without manual intervention. The system serves itself by autonomously detecting anomalies and triggering the recording function, eliminating the need for users to manually operate start switches during emergencies.
Solution Approach 2:
The mechanical manual start switch operation is replaced with an automated sensor-based detection system. Sensors detect event conditions and electronically trigger the recording function, substituting the mechanical user interaction with an automated electronic response system that reacts instantly to detected events.
2Adaptability or versatility
If single information-capturing device is carried, then device portability is maintained, but media data capture is limited to single angle
Solution Approach 1:
The system enables a single device to perform multiple functions by automatically activating and broadcasting event data to multiple neighboring devices. The universal event message can be received and processed by any device within the network, allowing one device to contribute to multi-angle coverage through coordinated operation with other devices.
Solution Approach 2:
A communication network acts as an intermediary between the event detection and media capture functions. When an event is detected, the system broadcasts information through the network to neighboring devices, which then activate their recording functions. This intermediary network enables coordinated multi-device operation without requiring complex direct connections between all devices.
3Loss of information
If information-capturing device without networking capability is used, then device simplicity is maintained, but remote event notification is not possible
Solution Approach 1:
Nearby devices with networking capabilities serve as intermediaries for non-networked devices. When an event is detected by a device without networking capability, it broadcasts the event message to neighboring devices that do have networking capabilities, which then forward the information to remote servers. This intermediary approach enables remote notification without requiring the original detecting device to have networking functionality.
Solution Approach 2:
The system creates a universal event notification network where devices with or without networking capabilities can participate. Devices without networking capabilities can still detect and broadcast events, while devices with networking capabilities handle the remote communication function. This multi-functional approach allows the system to operate regardless of individual device networking capabilities.

AI summary
An information-capturing device includes a near-field communication module, a video recording unit, a storing unit, and a controlling unit. The controlling unit is coupled to the near-field communication module, the video recording unit, and the storing unit. The near-field communication module receives an event message including a destination information. The video recording unit captures an ambient data. The storing unit stores a first identification code. The controlling unit compares the first identification code with the dedicated identification code specified by the destination information contained in the event message. The controlling unit starts the video recording unit if the first identification code matches the dedicated identification code specified by the destination information contained in the event message. The controlling unit broadcasts the event message through the near-field communication module if the first identification code does not match the dedicated identification code specified by the destination information contained in the event message.
