Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional manual methods with gauze and hardening polymeric material are used for cranial mapping, then the mold can be created, but the process is time-consuming and requires large quantities of disposable materials
Solution Approach 1:
The patent replaces the mechanical manual molding process with optical 3D scanning technology. A structured light scanner projects light patterns onto the patient's scalp and captures the reflected light to create a digital 3D model, eliminating the need for physical gauze molds and hardening materials while significantly reducing measurement time
Solution Approach 2:
The patent creates a digital copy (digital twin) of the patient's cranial conformation through 3D scanning instead of using physical molds. This digital model can be stored, reused, and modified without requiring additional physical materials or time-consuming remolding processes
2Ease of manufacture
If traditional manual methods are used for creating micro-holes and applying hair, then the process can be completed, but it requires large amounts of time and is not mechanized
Solution Approach 1:
The patent replaces manual mechanical processes with automated robotic systems. A robotic arm equipped with precision tools automatically creates micro-holes in the base material and applies hair follicles, ensuring consistent precision while dramatically increasing production speed and eliminating manual labor bottlenecks
Solution Approach 2:
The patent transforms the production process from manual operation to automated control by changing key parameters such as hole diameter, depth, spacing, and hair application force through programmable robotic systems. This allows for precise reproduction of natural hair patterns while maintaining high production efficiency
3Ease of manufacture
If hair is injected into the base material, then the application process is simplified, but the durability is reduced over time
Solution Approach 1:
The patent creates pre-prepared micro-holes in the base material before hair application. These holes are specifically designed with optimal dimensions and positioning to mechanically anchor hair follicles, ensuring long-term durability while maintaining a simplified overall process through proper upfront preparation
Solution Approach 2:
The patent employs a suction system that uses negative pressure to secure hair follicles in the micro-holes. The suction mechanism creates a firm mechanical connection between the hair and base material, significantly improving durability compared to injection methods while maintaining ease of application through automated control
