Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Home security systems often require a wireless fidelity network to operate, which limits their mobility and functionality, as many locations lack a reliable Wi-Fi network or the network may not reach the device, making it impossible to use them outside the home.
Innovation Solution
A mobile video surveillance system that includes a camera, transceiver, processor, and movement detection unit, allowing video streaming over various wireless networks, including broadband, enabling operation in any location with internet access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If home security systems use wireless fidelity network connection, then video transmission capability is enabled, but mobility and location flexibility are limited
Solution Approach 1:
The security device is designed to support multiple network connection types including Wi-Fi, cellular networks, and other wireless broadband networks. This multi-functionality allows the device to adapt to different locations and network environments, resolving the contradiction between reliable video transmission and location flexibility by providing universal network compatibility.
2Stability of the object's composition
If home security systems are fixed to wireless fidelity network, then stable video streaming is achieved, but device mobility is reduced
Solution Approach 1:
The device incorporates dynamic network selection capability, automatically switching between Wi-Fi and cellular networks based on availability and signal strength. This dynamic adaptation maintains stable video streaming while enabling device mobility, as the system can operate in fixed or mobile locations without requiring permanent Wi-Fi infrastructure.
3Ease of operation
If wireless fidelity network is required for operation, then video capture and transmission function is enabled, but usability in remote locations is prevented
Solution Approach 1:
The device uses cellular networks as an intermediary communication channel when Wi-Fi is unavailable. The cellular network acts as a mediator that enables video transmission in remote locations without requiring local Wi-Fi infrastructure, thus maintaining ease of operation while expanding adaptability to remote areas.
4Reliability
If access point coverage is limited, then wireless fidelity network can be established, but security device placement options are restricted
Solution Approach 1:
The device changes its network connection parameters dynamically, switching from Wi-Fi to cellular network based on environmental conditions. This parameter change eliminates the need for careful placement relative to access points, simplifying deployment while maintaining reliable network connection across diverse locations.
