Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing detection systems for protective devices, such as helmets, fail to ensure proper usage and closure, leading to safety risks during accidents, particularly in vehicles where helmet usage is mandatory.
Innovation Solution
A detection device integrated with a protective device, featuring a status sensor and a wireless communication module that transmits the closure status information, allowing for real-time monitoring and feedback on the helmet's locking state, enhancing user safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a detection device with wireless communication module is integrated into the protective device, then the reliability of safety monitoring is improved, but the device complexity increases
Solution Approach 1:
The detection device is integrated into the protective device itself, with the status sensor and wireless communication module nested within the helmet structure. This nesting approach ensures the monitoring system remains reliable while minimizing additional complexity by embedding components within the existing protective device framework.
Solution Approach 2:
The protective device serves multiple functions: it provides physical protection while simultaneously integrating detection and wireless communication capabilities. This multi-functionality reduces the need for separate monitoring devices, thereby improving reliability without proportionally increasing overall system complexity.
2Measurement precision
If real-time status information transmission is implemented, then the measurement precision of closure state monitoring is improved, but the use of energy increases
Solution Approach 1:
The wireless communication module transmits status information periodically or triggered by state changes rather than continuously. This periodic transmission maintains precise monitoring capability while significantly reducing energy consumption compared to continuous real-time transmission.
Solution Approach 2:
The system implements feedback by transmitting status information only when the closure state changes or at scheduled intervals. This feedback mechanism ensures accurate monitoring of closure state while optimizing energy usage by avoiding redundant transmissions of unchanged status data.
