Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If traditional lighting devices are used for long periods, then energy consumption increases, but replacing or modifying these devices requires significant money and manpower
Solution Approach 1:
The lighting device is segmented into modular components: a power supply unit, a control circuit unit, and a replaceable intelligent sensor unit. This segmentation allows the sensor to be replaced independently without modifying the entire lighting device, reducing modification costs while enabling energy-saving intelligent control functions.
Solution Approach 2:
The lighting device is designed with universal interfaces and standardized power supply connections that can accommodate different types of intelligent sensors. The device can perform multiple functions including lighting control, energy monitoring, and remote communication through the replaceable sensor module, reducing the need for device replacement.
2Adaptability or versatility
If traditional lighting devices are used, then basic lighting function is provided, but intelligent functions are lacking which limits application
Solution Approach 1:
The intelligent sensor is separated into an independent replaceable module, allowing the basic lighting device to remain simple while the intelligent functions are contained in the sensor unit. This segmentation enables users to upgrade intelligent capabilities by simply replacing the sensor module without increasing overall device complexity.
Solution Approach 2:
The intelligent sensor acts as an intermediary between the simple lighting device and the external control system. It provides intelligent functions such as motion detection, ambient light sensing, and wireless communication without requiring complex circuitry in the main lighting device, thus maintaining device simplicity while enhancing adaptability.
3Ease of operation
If traditional lighting devices are used, then lighting function is provided, but user monitoring and maintenance capability is insufficient
Solution Approach 1:
The intelligent sensor serves as an intermediary that provides monitoring and communication functions. It can detect operational parameters, diagnose issues, and communicate with users or maintenance systems wirelessly, enabling easy monitoring and maintenance without adding complex control circuits to the main lighting device.
Solution Approach 2:
The intelligent sensor enables self-monitoring and self-diagnosis capabilities of the lighting device. It can detect faults, report status, and alert users to maintenance needs automatically, reducing the need for complex manual monitoring systems and enabling easy operational oversight.
