Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual checking methods are used to verify PPE presence, then device complexity is reduced, but reliability of safety checks deteriorates due to non-automatic and irregular verification
Solution Approach 1:
The system enables automatic self-verification of PPE presence through electronic tags embedded in equipment and automated detection by the control unit, eliminating the need for manual checking by operators or supervisors. The system autonomously tracks equipment location and verifies compliance with safety requirements.
Solution Approach 2:
The patent replaces manual mechanical checking processes with an automated electronic detection system using radio frequency identification (RFID) tags, transponders, or other electronic identifiers. The control unit automatically detects and verifies equipment presence, substituting human-operated manual checks with automated electronic verification.
2Productivity
If automated detection systems are implemented, then productivity of safety verification is improved through real-time monitoring, but device complexity increases due to additional detection equipment
Solution Approach 1:
The control unit performs multiple functions including detecting equipment presence, verifying PPE compliance, tracking equipment location, and providing real-time alerts. The electronic tags serve both identification and tracking purposes simultaneously. The system can monitor multiple pieces of equipment and provide comprehensive safety verification across different work areas.
Solution Approach 2:
Electronic tags or transponders are attached to equipment as intermediary elements that enable automatic detection and tracking. These passive or active tags contain identification information that the control unit reads to verify equipment presence and location, facilitating automated verification without requiring complex active sensors in each piece of equipment.
3Reliability
If continuous real-time monitoring is implemented, then reliability of safety compliance is improved, but use of energy increases due to continuous operation of detection systems
Solution Approach 1:
The system can implement periodic polling of equipment tags rather than continuous monitoring, checking equipment presence at regular intervals. The control unit can adjust the monitoring frequency based on safety requirements and equipment criticality, reducing energy consumption while maintaining adequate safety verification.
Solution Approach 2:
The system uses passive RFID tags or low-cost electronic identifiers that require minimal to no power, transferring the energy burden to the control unit's detection system. These simple tags can be easily replaced if needed, while the main energy-consuming components are centralized in the control unit that can manage power consumption more efficiently.
