Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a simple lens structure is used in IPL devices, then the device complexity is reduced, but the light concentration and fractional effects are insufficient
Solution Approach 1:
The lens is divided into multiple functional units: a light receiving unit that receives light from the light source, a light reflecting unit that reflects light, and a light concentrating unit that concentrates light. This segmentation allows each unit to perform its specific function optimally, achieving high light concentration without requiring an overly complex overall structure.
Solution Approach 2:
Different regions of the lens are assigned different optical properties. The light reflecting unit has high reflectivity to redirect light, while the light concentrating unit has specific refractive properties to focus light. This local differentiation of optical characteristics enables efficient light concentration while maintaining a relatively simple lens structure.
2Stability of the object's composition
If light is evenly distributed across the treatment area, then the illumination uniformity is improved, but the fractional effects are reduced
Solution Approach 1:
The lens creates a non-uniform light distribution pattern by segmenting the optical path into reflecting and concentrating units. This results in discrete high-intensity light spots rather than uniform illumination, which is essential for generating fractional effects that stimulate collagen production and skin regeneration.
Solution Approach 2:
The lens produces localized high-intensity light spots at specific positions on the treatment area while leaving other areas with lower intensity. This local variation in light intensity creates the fractional effect pattern needed for effective skin treatment, contrasting with uniform illumination that would not produce the desired regenerative response.
3Ease of manufacture
If the lens structure is simplified for ease of manufacture, then the manufacturing precision of light focusing is reduced
Solution Approach 1:
The lens is designed as a composite structure with distinct reflecting and concentrating units that can be manufactured using standard optical manufacturing techniques. Each unit has a well-defined function and geometry, making them easier to manufacture with high precision compared to a single complex lens element.
Solution Approach 2:
Each local unit (reflecting or concentrating) has a simple, well-defined optical function that can be achieved with standard manufacturing tolerances. The light concentrating unit, for example, can be designed as a simple lens or refractive element with a specific focal point, ensuring high light focusing accuracy while remaining manufacturable.
