Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional goggles struggle to provide a comfortable and secure fit for users due to the variability in face shapes and sizes, as standard sizes cannot adequately accommodate individual differences, leading to discomfort during extended wear.
Innovation Solution
A goggle customization system that uses 3D face scanning technology to generate custom-fit goggle frames and components, combining user-specific geometry with standard components, allowing for precise fitting through 3D printing and assembly with standard-size components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If standard-size goggle frames are used, then manufacturing cost and inventory management are simplified, but fit comfort and security are insufficient for users with varying face shapes and sizes
Solution Approach 1:
The system performs 3D face scanning and custom frame generation in advance before manufacturing. The customization process is completed digitally beforehand, allowing standard manufacturing processes to produce custom-fitted goggles without adding complexity to the physical manufacturing stage.
Solution Approach 2:
The system varies geometric parameters of the goggle frame based on individual face scan data. By adjusting parameters such as frame curvature, width, and depth to match specific user measurements, the system achieves precise fit customization while maintaining compatibility with standard manufacturing capabilities.
2Manufacturing precision
If 3D scanning and custom manufacturing are implemented, then fit precision and comfort are improved, but manufacturing time and production complexity increase
Solution Approach 1:
The manufacturing process is divided into modular components: digital scanning, 3D modeling, parameter optimization, and fabrication. This segmentation allows parallel processing of different goggle components and enables standardized sub-assemblies to be manufactured efficiently while custom portions are produced on-demand.
Solution Approach 2:
The system creates digital 3D models and prototypes virtually before physical manufacturing. By working with digital copies and simulations, the system validates design accuracy and fit precision without consuming physical materials or manufacturing time, reducing waste and accelerating the design-to-production cycle.
3Ease of operation
If fully custom goggle frames are manufactured for each user, then fit comfort is maximized, but manufacturing cost and production time increase significantly
Solution Approach 1:
The system designs custom goggle frames with standardized interfaces and common components that can be shared across different user configurations. By maintaining universal mounting points, lens attachments, and adjustment mechanisms, the system reduces the number of unique parts that need to be manufactured while preserving custom fit characteristics.
Solution Approach 2:
The system applies full customization only to the portions of the goggle frame that directly contact the user's face, while keeping non-contact portions standardized. This selective customization approach maximizes comfort benefits in critical areas while minimizing manufacturing complexity and cost in less critical areas.
