Eyewear Measuring Mold for Pupil Height and Temple Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing eyewear fitting technologies fail to accurately measure pupil height and multifocal lens segment height, and adjust temples properly, leading to improper fitting of progressive lenses.
Innovation Solution
A multi-use measuring device with a top, middle, and bottom section, featuring temple adjusters, viewing slots, and measuring slots, allowing precise pupil height and multifocal lens segment height measurement, and accurate temple adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a traditional single-function measuring tool is used, then the device complexity is low, but the measurement precision and fitting accuracy deteriorate
Solution Approach 1:
The patent combines multiple measuring functions (pupil height measurement, multifocal lens segment height measurement, and temple adjustment) into a single integrated mold device. The mold includes vertically spaced first measuring means for pupil height, second measuring means for lens segment height, and temple adjustment means, all integrated into one device structure that can perform multiple measurements and adjustments sequentially
Solution Approach 2:
The measuring mold is designed as a universal device that can measure different parameters (pupil height, lens segment height) and adjust temple arms for multiple eyewear frames. The device includes multiple sets of measuring means and temple adjustment means that can accommodate various frame styles and measurement requirements, making it applicable to diverse eyewear fitting scenarios
2Productivity
If separate tools are used for measuring pupil height, lens segment height, and adjusting temples, then each measurement function can be optimized, but the loss of time increases due to multiple tool changes
Solution Approach 1:
The patent integrates multiple measuring and adjustment functions into a single mold device that can measure pupil height, lens segment height, and adjust temple arms without requiring tool changes. The vertically spaced first and second measuring means are both incorporated into the same device structure, allowing sequential measurements to be performed by the same tool
Solution Approach 2:
The universal measuring mold can perform multiple functions including measuring pupil height, measuring lens segment height, and adjusting temple arms for different eyewear frames. This multi-functional design eliminates the need to switch between separate tools for each measurement and adjustment task, improving fitting efficiency
3Manufacturing precision
If conventional measuring devices are used, then the device complexity remains low, but the manufacturing precision of lens fitting deteriorates
Solution Approach 1:
The measuring mold is divided into distinct functional segments: first measuring means for pupil height positioned at a first vertical level, second measuring means for lens segment height positioned at a second vertical level, and temple adjustment means. This segmentation allows each measuring function to be precisely calibrated independently while maintaining overall device integration
Solution Approach 2:
The mold incorporates pre-marked reference lines and measuring indicators that are预先 positioned to guide accurate measurements. The first and second measuring means include pre-defined measurement scales and reference points that enable precise measurement without requiring complex calculation or adjustment during the fitting process
