Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional infrared irradiation devices irradiate only one type of infrared light, then the device structure is simple, but it cannot select appropriate wavelengths according to different physical structures of users and inflammation levels
Solution Approach 1:
The device divides the infrared irradiation function into multiple independent LED generators, each capable of emitting different wavelengths (near-infrared and far-infrared). This segmentation allows selective activation of specific wavelength generators based on user needs, providing adaptability while maintaining manageable complexity through modular design
Solution Approach 2:
The device incorporates multiple types of LEDs (near-infrared and far-infrared) within a single infrared irradiation device, enabling it to perform multiple functions by selecting different wavelength combinations. This multi-functionality allows the device to adapt to different physical structures and inflammation levels without requiring multiple separate devices
2Area of stationary object
If multiple LEDs with different wavelengths are disposed close together, then the device size is reduced, but the LEDs may interfere with each other's light emission
Solution Approach 1:
Each LED generator is designed with specific optical characteristics and emission patterns tailored to its wavelength type. The near-infrared and far-infrared LEDs are positioned and oriented to optimize their respective light paths toward the target area, minimizing cross-interference while maintaining compact dimensions
Solution Approach 2:
The LEDs are arranged in a three-dimensional configuration rather than a simple linear or planar layout. By utilizing spatial positioning in multiple dimensions, the device achieves compact size while ensuring that light beams from different wavelength LEDs converge on the target area without significant mutual interference
