Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If multiple needles are used for skin treatment, then treatment coverage is improved, but difficulty in performing uniform depth insertion on curved skin increases
Solution Approach 1:
The device employs elastic parts that can dynamically bend and deform to adapt to curved skin surfaces. The elastic parts are connected to the rotating part and needle holder, allowing the entire assembly to flex and conform to the contours of the face, enabling uniform needle insertion depth across multiple needles even on curved surfaces
Solution Approach 2:
The device changes the physical state of the elastic parts from rigid to flexible, allowing them to deform under compression. This parameter change enables the elastic parts to absorb variations in skin curvature, maintaining consistent needle insertion depth across multiple needles while adapting to different facial contours
2Manufacturing precision
If needles are inserted to uniform depth on curved skin, then treatment precision is improved, but device complexity increases
Solution Approach 1:
The device uses elastic parts as flexible structural elements that can bend and deform to match curved skin surfaces. These elastic parts serve as both structural support and adaptive elements, eliminating the need for complex mechanical adjustment mechanisms while maintaining uniform needle insertion depth across curved facial surfaces
Solution Approach 2:
The device incorporates a rotating part that can rotate about a rotating shaft, allowing the needle array to orient itself at different angles. This rotational capability combined with the elastic parts' flexibility enables the device to adapt to the curved geometry of the face, maintaining uniform insertion depth while simplifying the overall device structure through geometric adaptation
3Ease of operation
If the device structure is simplified for easy operation, then ease of operation is improved, but ability to perform three-dimensional treatment on curved surfaces deteriorates
Solution Approach 1:
The elastic parts provide dynamic adaptation to curved surfaces through their inherent flexibility. When the rotating part rotates or when the device is positioned on curved skin, the elastic parts automatically bend and deform to maintain contact and uniform needle insertion depth, providing three-dimensional treatment capability without requiring complex mechanical adjustment mechanisms
Solution Approach 2:
The elastic parts serve multiple functions simultaneously: they provide structural support for the needle holder, enable adaptation to curved surfaces through bending, and maintain uniform needle insertion depth. This multi-functionality allows the device to perform three-dimensional treatment on various facial contours while keeping the device structure simple and easy to operate
