Customizable Eyeglass Bridge for Morphological Fit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for manufacturing eyeglasses are time-consuming and inefficient, requiring multiple frame sizes and designs to be tried on to ensure a comfortable and proper fit, which is impractical for in-person fittings and impossible for online sales due to the lack of precise virtual try-on solutions.
Innovation Solution
The development of eyeglasses with a customizable bridge that can be adjusted based on morphological parameters of the wearer, allowing for standardized half-frames to be interconnected with bridges of varying geometrical features to fit individual nose shapes and interpupillary distances, enabling online ordering and self-assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If prebuilt frames with predetermined dimensions are used, then manufacturing and inventory management is simplified, but the fit and comfort for individual wearers cannot be optimized
Solution Approach 1:
The frame is divided into separable components: standardized half-frames and interchangeable bridges. The bridge is provided as a separate element that can be detached and replaced, allowing the same half-frames to be combined with different bridges to suit different wearer morphologies while maintaining standardized manufacturing processes
Solution Approach 2:
The bridge incorporates adjustable geometric parameters including length, interior width, and interior height. These parameters can be modified to match different interpupillary distances and nose shapes, enabling the frame to adapt to various wearer characteristics without requiring complete frame redesign
2Manufacturing precision
If multiple frame sizes and designs are provided for trying on, then the fit accuracy is improved, but the time required for fitting increases significantly
Solution Approach 1:
The bridge is designed with predetermined geometric parameters that can be selected in advance based on the wearer's morphological measurements (interpupillary distance, nose shape). This preliminary determination of bridge specifications eliminates the need for time-consuming trial-and-error fitting of multiple complete frames
Solution Approach 2:
By separating the bridge from the half-frames, the fitting process is streamlined to only require bridge selection and attachment rather than complete frame trying-on. The standardized half-frames eliminate the need to try multiple frame designs, reducing fitting time while maintaining accuracy
3Ease of operation
If traditional frame trying-on methods are used, then the comfort and stability of the eyeglasses are ensured, but online ordering without physical inspection becomes impractical
Solution Approach 1:
The bridge's geometric parameters (length, width, height) can be determined from remote morphological measurements such as interpupillary distance and nose shape data obtained through online questionnaires or imaging. This allows the appropriate bridge to be selected and provided to the customer for home assembly, enabling comfortable and stable fit assurance without in-person trying on
Solution Approach 2:
The invention enables creation of a physical bridge component based on digital or measured data obtained remotely. The bridge geometry is copied from the wearer's morphological parameters, allowing accurate replication of the required fit characteristics without direct physical interaction during the ordering process
