Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the housing and care module substrate are formed with fixed curvature, then the manufacturing process is simple, but the device cannot adapt to different user neck characteristics
Solution Approach 1:
The housing and care module substrate are designed with variable curvature instead of fixed curvature, allowing the device to dynamically adapt to different user neck characteristics. The curvature can be adjusted within a predetermined range to match individual neck thickness and length variations, resolving the contradiction between adaptability and device complexity by making the structure dynamically adjustable rather than statically complex
Solution Approach 2:
The invention changes the curvature parameter of the housing and care module substrate within a predetermined range to adapt to different user neck characteristics. By allowing the curvature parameter to vary rather than remaining fixed, the device achieves adaptability to different users without requiring completely different designs for each user type
2Illumination intensity
If the light sources are arranged in a fixed pattern, then the manufacturing precision is easier to control, but the light output uniformity varies across different users
Solution Approach 1:
The care module substrate with variable curvature allows the light source arrangement to dynamically adapt to different user neck characteristics. While the physical positions of light sources on the substrate remain fixed during manufacturing, the substrate's curvature itself becomes variable, allowing the light output pattern to be optimized for different users without requiring complex real-time repositioning mechanisms
Solution Approach 2:
The invention applies curvature to the housing and care module substrate to match the natural contour of the user's neck. By forming these components with variable curvature in the first and second directions, the device conforms better to individual neck shapes, improving light output uniformity across different users while maintaining relatively simple manufacturing processes
3Adaptability or versatility
If the device is designed to fit all neck sizes, then the versatility is improved, but the fit quality deteriorates for individual users
Solution Approach 1:
The invention allows the curvature parameters of the housing and care module substrate to vary within a predetermined range, enabling the device to adapt to different user neck characteristics. This parameter variation approach maintains versatility across different users while improving fit quality for each individual by matching their specific neck dimensions
