Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional wiring methods are used for high bay lighting units, then electrical connections can be made, but installation time increases and wiring mistakes occur due to complex wiring requirements and multiple tools needed
Solution Approach 1:
The patent applies preliminary action by pre-assembling the lighting unit with all internal wiring, terminal blocks, and electrical connections already installed and tested during manufacturing. This includes pre-connecting the driver, electrochemical cell, switching circuit, and LED modules with factory-installed wiring, so that during installation the unit requires only final cable connections at externally accessible terminal blocks, eliminating complex on-site wiring operations
Solution Approach 2:
The patent extracts the complex internal wiring and electrical connections from the installation process by incorporating them as pre-installed components within the lighting unit. The terminal blocks and connection points are brought to externally accessible locations on the unit's exterior, allowing installers to connect only the final supply cables without dealing with internal wiring complexity, effectively removing the wiring complexity from the installation task
2Adaptability or versatility
If multiple electrical connections and junction boxes are required for emergency and dimmable lighting configurations, then the lighting unit can have advanced functionality, but device complexity increases making installation more difficult and error-prone
Solution Approach 1:
The patent merges multiple electrical connection functions into a single integrated lighting unit. The driver for LED operation, the electrochemical cell for emergency power, the switching circuit for emergency mode activation, and dimming control circuits are all combined within one unit with unified external terminal blocks. This integration allows emergency, dimmable, and sensor-controlled functionalities to coexist without requiring separate junction boxes or multiple disconnected components, reducing installation complexity while maintaining advanced lighting capabilities
Solution Approach 2:
The patent applies universality by designing the lighting unit with multi-functional electrical terminal blocks that can accommodate various wiring configurations for normal operation, emergency mode, dimming control, and sensor integration. The terminal blocks are designed to accept multiple cable types and configurations, allowing the same unit to be installed in different functional modes (emergency lighting, dimmable lighting, sensor-controlled lighting) without requiring different hardware or complex additional connections
3Shape
If installers work at height to install high bay lighting units, then the lights can be positioned correctly for high bay application, but installation safety risks increase and installation time increases
Solution Approach 1:
The patent applies preliminary action by pre-assembling the entire lighting unit including all electrical connections, terminal blocks, and mounting hardware on the ground before installation. The unit is tested and verified to be electrically correct during manufacturing, then hoisted as a complete assembly to the high bay mounting position. This eliminates the need for installers to work at height performing complex wiring tasks, reducing both safety risks and installation time while maintaining the correct high bay mounting position
