Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed lens plate is used in the conventional LED lamp, then the structure is simple and manufacturing is easy, but the light distribution direction cannot be adjusted and adaptability is poor
Solution Approach 1:
The LED lamp panel is divided into multiple independently controllable light-emitting areas (first area, second area, third area, fourth area), each corresponding to a different sector of the lens plate. This segmentation allows selective activation of specific light-emitting elements to achieve different light distribution directions without physically moving the lens plate, thus improving adaptability while maintaining structural simplicity.
Solution Approach 2:
The patent introduces an angle controller with multiple control switches that enable dynamic control over which light-emitting areas are activated. By dynamically switching between different combinations of light-emitting elements, the system can adjust light distribution direction flexibly without mechanical movement, resolving the contradiction between adaptability and structural complexity.
2Ease of operation
If the lens plate position is fixed, then the manufacturing cost is low and ease of manufacture is high, but the light emission angle cannot be adjusted and operational flexibility is limited
Solution Approach 1:
The patent replaces the mechanical approach of physically moving or rotating the lens plate with an electronic control system. The angle controller and control switches electronically manage which light-emitting elements are activated to achieve different light angles, eliminating the need for mechanical adjustment mechanisms and maintaining manufacturing simplicity while improving operational flexibility.
Solution Approach 2:
The system changes the operational parameters by selectively activating different light-emitting elements in different areas of the LED lamp panel. By controlling the electrical state (on/off) of specific light-emitting groups, the system achieves variable light distribution patterns without changing the physical configuration, thus maintaining ease of manufacture while enhancing operational flexibility.
3Adaptability or versatility
If multiple control switches and electronic switches are added to enable angle adjustment, then light distribution control is improved, but the device complexity increases
Solution Approach 1:
The control system is segmented into multiple independent control switches (first control switch, second control switch, third control switch, fourth control switch), each managing a specific light-emitting area. This modular segmentation allows each switch to be independently controlled and maintained, reducing the overall system complexity while providing comprehensive light angle control capability.
Solution Approach 2:
Each control switch is locally assigned to control a specific area of the LED lamp panel, creating localized control zones. This local quality approach ensures that each part of the control system has a dedicated function, making the overall complex system manageable through clear functional separation and reducing the cognitive load on the user.
4Adaptability or versatility
If the LED lamp panel is divided into multiple areas with independent control, then light distribution direction adjustment is enabled, but the manufacturing precision requirements increase
Solution Approach 1:
The LED lamp panel is segmented into distinct areas (first area, second area, third area, fourth area) with clearly defined boundaries and corresponding light-emitting elements. This segmentation allows for standardized manufacturing of each area module, reducing the overall manufacturing precision requirements by enabling modular production and assembly while still achieving precise light distribution control through electronic switching.
