Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If comb teeth are added to separate hair, then hair separation is improved, but laser light output is blocked and irradiation efficiency is reduced
Solution Approach 1:
The patent removes the comb teeth structure from the device. Instead of having protruding comb teeth that block laser light, the device uses a smooth contact surface that allows laser light to pass through unobstructed while still providing hair separation function through the overall device structure.
Solution Approach 2:
The patent introduces a transparent or translucent plate as an intermediary structure. This plate allows laser light to pass through while providing the necessary structural support and hair separation function, replacing the traditional comb teeth that directly blocked the light path.
2Ease of operation
If comb teeth configuration is used, then hair separation is achieved, but distance between laser module and scalp increases
Solution Approach 1:
The patent removes the comb teeth that created the distance gap between the device and scalp. The smooth contact surface design allows the laser modules to be positioned closer to the scalp, eliminating the distance increase caused by protruding comb teeth.
3Reliability
If traditional TO-CAN packaging is used for laser modules, then reliability is maintained, but processing speed is slow and cost is high
Solution Approach 1:
The patent changes the packaging type of laser modules from traditional TO-CAN to SMD (Surface Mount Device) packaging. This parameter change enables faster processing speeds and lower costs while maintaining the necessary reliability for hair growth treatment applications.
4Reliability
If traditional TO-CAN packaging is used, then reliability is maintained, but device volume and weight increase
Solution Approach 1:
The patent changes the packaging type from TO-CAN to SMD, which significantly reduces the volume and weight of each laser module. The SMD packaging is much more compact, allowing for a smaller overall device size while maintaining reliability for the intended application.
