Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If LED light board has fixed color temperature, then manufacturing cost is reduced, but adaptability to different market specifications deteriorates
Solution Approach 1:
The LED light board transitions from a static fixed color temperature design to a dynamic adjustable color temperature design. The control system allows the color temperature to be changed according to different market requirements and user preferences, enabling the same hardware to adapt to various specifications without restocking.
Solution Approach 2:
The invention changes the operating parameters of the LED light board by introducing controllable color temperature adjustment. Different color temperatures can be selected based on market demands, allowing the product to meet diverse specifications while using the same physical components.
2Device complexity
If color temperature is adjustable only after power-on, then device complexity is reduced, but ease of operation before installation deteriorates
Solution Approach 1:
The invention enables preliminary configuration of display conditions before the LED light board is powered on. Users can pre-set color temperature and other parameters during installation or before first use, making adjustments easier and avoiding the need to power on the device just for configuration.
Solution Approach 2:
A control system acts as an intermediary between the user and the LED light board, enabling parameter configuration before power-on. This intermediary system stores the display conditions and applies them automatically when the device is powered on, bridging the gap between pre-installation setup and actual operation.
3Ease of operation
If complex control system is installed for pre-adjustment, then ease of operation is improved, but device complexity and cost increase
Solution Approach 1:
The LED light board system performs self-configuration by storing display conditions in its own memory before power-on. The device automatically applies the pre-set parameters when powered on, eliminating the need for complex external control systems or manual adjustment mechanisms.
Solution Approach 2:
The invention creates a simplified control approach by copying the display condition settings directly into the light board's memory. This allows pre-adjustment functionality without requiring complex real-time control systems, as the settings are stored and executed automatically.
4Measurement precision
If remote control is required for each lamp, then individual control precision is improved, but ease of operation and installation cost deteriorate
Solution Approach 1:
The invention merges the control functionality into a centralized system that can manage multiple LED light boards. Instead of requiring separate remote controls for each lamp, a single control interface can configure and manage multiple devices, simplifying operation and reducing costs.
Solution Approach 2:
The control system is designed with multi-functionality to manage multiple LED light boards simultaneously. A universal control mechanism can set display conditions for several lamps at once, eliminating the need for individual remote controls while maintaining precise control over each device.
