Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for monitoring operatives in hazardous environments face challenges in maintaining reliable real-time communication, especially in areas with unreliable or absent public cellular networks, leading to potential disruptions in data transmission and hazard alerts.
Innovation Solution
A system comprising a base station, clothing with illuminatable devices connected via a wiring loom, and non-cellular radio devices, where control units include a processor and cellular radio communication modules to transmit data over cellular networks when available, and switch to non-cellular networks when cellular signals are lost, ensuring continuous data communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If operatives use public cellular networks for data transmission, then real-time communication is achieved, but communication reliability deteriorates in areas with weak or no cellular coverage
Solution Approach 1:
The system dynamically changes the communication parameter (network type) based on signal availability. When cellular signal strength falls below a threshold, the system automatically switches from cellular network to non-cellular radio network, maintaining communication reliability while adapting to changing environmental conditions
Solution Approach 2:
The communication system transitions from a static single-network approach to a dynamic multi-network approach. The control unit continuously monitors cellular signal availability and dynamically selects the appropriate network type (cellular or non-cellular) to maintain reliable data transmission in varying environmental conditions
2Reliability
If the system switches to non-cellular networks when cellular signals are lost, then communication reliability is improved, but device complexity increases
Solution Approach 1:
The control unit is designed with multi-functionality, capable of operating on both cellular and non-cellular networks. This universal design allows a single device to handle multiple communication protocols and network types, managing complexity through integrated multi-network support rather than separate dedicated systems
Solution Approach 2:
The control unit acts as an intermediary that manages communication between the monitoring devices and the base station through different network types. It provides a unified interface that abstracts the underlying network complexity, automatically routing data through cellular or non-cellular networks based on availability
3Reliability
If continuous monitoring is implemented, then operational safety is enhanced, but energy consumption increases
Solution Approach 1:
The system implements periodic monitoring and transmission instead of continuous operation. Condition detection devices periodically assess environmental parameters, and the control unit transmits data at scheduled intervals or when threshold changes are detected, reducing energy consumption while maintaining adequate safety monitoring
Solution Approach 2:
The system employs event-triggered transmission where the monitoring apparatus autonomously determines when data transmission is necessary based on detected condition changes. This self-service approach activates communication only when required, minimizing energy consumption while ensuring safety-critical data is transmitted promptly

AI summary
Operatives are monitored in a hazardous environment. A control unit is connected to a wiring loom embedded within an item of clothing having illuminatable devices and interface connectors. A monitoring device is connected to an interface connector and a radio device is connected to an interface connector. The control unit is activated to supply power to the connected monitoring device and the connected radio device. Condition data is conveyed from the monitoring device to the control unit. Uplink signals are transmitted from the control unit to a base station via a cellular radio communication module. Downlink signals are received at the control unit from the base station. Condition data is transmitted via the cellular radio communication module when the downlink signals are being received. Condition data is transferred to the non-cellular radio device when the downlink signals are not being received, for transmission to the base station.
