Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional distributed recording systems fail to function when recording devices malfunction, preventing the central host from receiving and processing image data.
Innovation Solution
A central recording device integrated with a recording unit, processing unit, storage unit, and connection unit, capable of generating and synchronizing image data from multiple sub-recording devices, and uploading to a server, even in the absence of functioning sub-recording devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If multiple sub-recording devices are used to achieve comprehensive image recording, then the coverage and recording capability are improved, but the system reliability deteriorates because the central host cannot function when sub-recording devices fail
Solution Approach 1:
The central recording device is designed to perform multiple functions: it can receive and process image data from sub-recording devices, generate its own central image data through the recording unit, and independently output streaming images. This multi-functionality ensures that the system maintains comprehensive image recording capability even when sub-recording devices fail.
Solution Approach 2:
The central recording device acts as an intermediary between the environment and the output system. It receives image data from sub-recording devices, synchronizes them with centrally captured images, and produces the final streaming output. This intermediary role allows the system to maintain functionality through the central device even when sub-devices are unavailable.
2Device complexity
If a traditional distributed recording system is used, then the system structure is simple, but the system reliability deteriorates because the central host cannot receive or process image data when recording devices are lost or malfunction
Solution Approach 1:
The central recording device integrates multiple functions including a recording unit for capturing environmental images, a processing unit for synchronizing and generating streaming images, a storage unit for saving data, and a connection unit for uploading. This integrated multi-functional design maintains system reliability while avoiding excessive complexity.
Solution Approach 2:
The central recording device performs preliminary actions by capturing and storing image data locally through its recording unit before needing to receive data from sub-recording devices. This preliminary data capture ensures that the central device has its own image data ready for processing and output, independent of sub-device status.
3Device complexity
If the central host relies on sub-recording devices for image data, then the system architecture is straightforward, but the system reliability worsens because image integration and streaming functions fail when sub-recording devices malfunction
Solution Approach 1:
The central recording device is designed with universal functionality to perform image capture, synchronization, processing, storage, and upload operations. This ensures that image integration and streaming capabilities are maintained through the central device itself, providing reliability independent of sub-recording device status.
Solution Approach 2:
The central recording device serves itself by capturing its own image data through the recording unit and processing it through the processing unit. This self-service capability ensures that the central device can maintain image integration and streaming functions independently, without complete reliance on sub-recording devices.

AI summary
A central recording device coupled to at least one sub-recording device and comprising a recording unit, a processing unit, a storage unit and a connection unit is provided. The recording unit is configured to generate central image data. The processing unit is coupled to the recording unit and configured to: receive at least one sub-image data from the sub-recording device; perform an image synchronization process on the central image data and the sub-image data to generate streaming image data; and in response to receiving a trigger signal, retrieve a portion of the streaming image data corresponding to a specified time period to generate a streaming video. The storage unit is coupled to the processing unit and configured to store the streaming video. The connection unit is coupled between the processing unit and a server, and configured to upload the streaming image data and the streaming video to the server.
