Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional battery systems are used in hazardous environments, then the lighting fixture can be powered, but the risk of ignition sources increases and safe operation cannot be ensured
Solution Approach 1:
The battery system is divided into separate modular components: a battery unit with conductive pins and a battery interface with corresponding pins. This segmentation allows the battery to be inserted and removed without disassembling the lighting fixture housing, reducing the risk of ignition sources in hazardous environments while maintaining reliable power supply.
2Reliability
If battery replacement requires disassembly of the lighting fixture, then secure connection can be ensured, but operation time is lost and complexity increases
Solution Approach 1:
The battery assembly is segmented into a removable battery unit and a fixed battery interface. The battery unit can be quickly inserted into or removed from the battery interface without disassembling the lighting fixture, ensuring secure electrical connection through aligned conductive pins while minimizing replacement time.
Solution Approach 2:
The battery unit is pre-assembled with conductive pins and the battery interface is pre-configured with corresponding pins and electrical connections. This preliminary preparation allows for rapid battery replacement without requiring on-site assembly or disassembly of the lighting fixture, reducing operational downtime.
3Reliability
If the battery system requires de-energizing the lighting fixture for replacement, then safety can be improved, but productivity decreases
Solution Approach 1:
The battery system is segmented into a removable battery unit and a fixed battery interface that remains connected to the lighting fixture. This allows battery replacement without de-energizing the fixture or disrupting other components, maintaining continuous operation while ensuring safety through isolated battery handling.
4Power
If conventional battery systems are used, then power supply can be provided, but the complexity of installation and maintenance increases
Solution Approach 1:
The battery system is segmented into standardized modular components with matching conductive pins and interfaces. This segmentation creates a simple, repeatable installation process where the battery unit is merely inserted into the battery interface, reducing installation and maintenance complexity while ensuring reliable power supply to the LED light sources.
