Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If optical energy is applied to target dermal pigmented cells, then treatment efficacy is improved, but excessive absorption by epidermal pigment causes harmful damage to outer skin tissue
Solution Approach 1:
The patent segments the optical treatment process into two distinct components: a low-energy imaging beam for detection and a high-energy treatment beam for therapy. This segmentation allows the system to first map pigment distribution and then selectively apply treatment energy only where needed, preventing unnecessary damage to epidermal tissue while maintaining effective treatment of dermal pigmentation.
Solution Approach 2:
The system performs preliminary imaging and pigment mapping before applying treatment energy. By first detecting the precise location and depth of pigmented cells through low-energy optical imaging, the system can pre-plan the treatment path and ensure that high-energy beams are delivered only to target areas, avoiding harmful effects on surrounding healthy tissue.
2Reliability
If high energy is used to reach deeper dermis, then treatment of dermal melasma is improved, but risk of thermal injury and cosmetic side effects increases
Solution Approach 1:
The patent implements a feedback mechanism where the imaging system continuously monitors pigment distribution and treatment response in real-time. The detected pigment information feeds back to control the treatment beam parameters, allowing dynamic adjustment of energy delivery to maintain effective treatment while preventing thermal injury and cosmetic side effects.
Solution Approach 2:
The system dynamically changes treatment parameters (energy level, pulse duration, spot size) based on real-time detection of pigment characteristics. By adjusting these parameters according to the specific properties of the target pigment and its depth, the system achieves effective dermal treatment while minimizing the risk of thermal injury and cosmetic complications.
3Productivity
If focal region depth is not precisely controlled, then treatment coverage is improved, but accuracy of targeting dermal layer while sparing epidermis deteriorates
Solution Approach 1:
The patent introduces an intermediary imaging system that acts as a mediator between the treatment beam and the target tissue. This imaging component provides real-time feedback on focal region positioning and pigment location, enabling precise depth control while maintaining comprehensive treatment coverage through guided beam delivery.
