Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single type of light at a set wavelength is provided, then the device structure is simple, but the device cannot perform different types of light therapy at various wavelengths
Solution Approach 1:
The light array is divided into multiple independently controllable LED emitters, each capable of operating at different wavelengths. This segmentation allows the device to provide multiple types of light therapy simultaneously or independently, resolving the contradiction between versatility and complexity by making each segment functional rather than adding a completely separate system.
Solution Approach 2:
The device integrates multiple wavelength LEDs into a single unified light therapy device that can perform various therapeutic functions. Each LED emitter is designed to be multi-functional through software control, allowing one device to replace multiple specialized devices, thereby achieving versatility without proportionally increasing physical complexity.
2Productivity
If multiple wavelengths of light are provided, then different therapeutic sessions can be conducted simultaneously, but the device complexity increases
Solution Approach 1:
Multiple LED emitters operating at different wavelengths are merged into a single integrated array that can be controlled simultaneously. This merging allows different therapeutic sessions to be conducted at the same time without requiring separate devices, increasing productivity while managing complexity through unified control architecture.
Solution Approach 2:
The device employs dynamic control of LED emitters through software, allowing flexible selection and combination of wavelengths based on therapeutic needs. This dynamic capability enables the system to adapt to different therapeutic protocols without physical reconfiguration, increasing productivity while keeping the physical structure relatively simple.
