Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If prefabricated LED boards are used to create linear lighting systems, then the system provides efficient lighting solutions, but the dimensions are limited to the types and sizes of available prefabricated boards
Solution Approach 1:
The LED lighting system is divided into multiple modular LED modules that can be independently positioned and adjusted. Each module contains a subset of LEDs arranged in a designated array, allowing the overall system to be segmented into manageable units that can be configured to achieve custom dimensions while maintaining lighting efficiency.
Solution Approach 2:
The LED modules are designed with adjustable positioning capabilities, allowing them to be dynamically reconfigured along the linear housing. This dynamic adjustability enables the system to adapt to different dimensional requirements without requiring completely different prefabricated board configurations.
2Length of moving object
If different numbers or lengths of prefabricated boards are combined to achieve custom lengths, then various light source lengths can be provided, but the dimensions remain limited to available board types and sizes
Solution Approach 1:
The LED modules incorporate adjustable positioning mechanisms that allow continuous or discrete adjustment of module positions along the linear housing. This dynamic positioning capability enables precise control of the overall light source length, providing dimensional flexibility that goes beyond the fixed dimensions of traditional prefabricated boards.
Solution Approach 2:
The modular LED modules are designed to be universal components that can be used in various configurations to achieve different light source lengths. The same module design can be replicated and positioned at different intervals, providing a universal solution that replaces the need for multiple specialized prefabricated board types.
3Adaptability or versatility
If LED modules are arranged in sliding overlapping relationship, then adjustable extension is provided, but the structure becomes more complex
Solution Approach 1:
The LED modules are arranged in a nested or overlapping configuration where modules are positioned within a common linear housing structure. This nesting approach allows for compact arrangement while maintaining adjustability, as modules can slide relative to each other within the confined space of the housing without requiring complex external adjustment mechanisms.
Solution Approach 2:
Multiple LED modules are merged into a single integrated linear lighting system within a common housing. The modules share common engagement surfaces and positioning mechanisms, combining their individual adjustment capabilities into a unified system that provides overall length adjustability without requiring separate complex mechanisms for each module.
