Eyewear Frame with Integrated Gridlines for PD and SH Measurement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current eyewear measuring systems require professional optical staff to measure pupillary distance and segment height, limiting the ability of retailers to dispense prescription optical frames, such as prescription sunglasses, due to the need for skilled professionals to take these key measurements.
Innovation Solution
An eyewear measurement system featuring standard frames with visible interconnecting gridlines on the lenses, allowing for simultaneous measurement of pupillary distance and segment height, enabling untrained personnel to accurately measure these parameters using a method that involves positioning the frame on the user's face and recording gridline coordinates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If professional optical staff use traditional measuring tools (pupilometer/ruler) to measure pupillary distance and segment height, then measurement precision is maintained, but device complexity and operational difficulty increase, requiring trained personnel
Solution Approach 1:
The patent combines multiple measurement functions (pupillary distance and segment height measurement) into a single eyewear frame structure with integrated gridlines on the lenses. This merging eliminates the need for separate measuring tools like pupilometers and rulers, reducing device complexity while maintaining measurement precision through the coordinated use of horizontal and vertical gridlines that simultaneously provide both measurement dimensions.
Solution Approach 2:
The eyewear frame serves multiple functions: it acts as both the actual eyewear product and the measuring instrument. The gridlines on the lenses provide universal measurement capability for both pupillary distance (horizontal measurement) and segment height (vertical measurement), allowing a single device to replace multiple specialized tools and enable untrained personnel to perform accurate measurements.
2Measurement precision
If professional optical staff perform measurements using traditional methods, then measurement accuracy is ensured, but ease of operation decreases due to requiring skilled professionals
Solution Approach 1:
The eyewear frame with integrated gridlines enables self-service measurement capability. When the frame is placed on the wearer's face, the gridlines automatically align with anatomical reference points, allowing untrained personnel to read measurements directly from the grid without requiring professional optical training. The system serves itself by providing built-in measurement guidance through the visual grid structure.
Solution Approach 2:
The patent employs visual differentiation through color coding or distinct marking of specific gridline intersections that correspond to measurement reference points. This visual enhancement makes it easier for untrained personnel to identify the correct measurement points on the grid, improving ease of operation while maintaining measurement precision through the structured grid system.
3Productivity
If retailers want to expand into prescription optical frames dispensing, then productivity increases, but the requirement for professional optical staff creates operational barriers
Solution Approach 1:
The integrated measurement system embedded in the eyewear frame enables untrained retail personnel to perform measurements independently without requiring professional optical staff. This self-service capability removes the operational barrier to expanding prescription frame dispensing, allowing any retail employee to accurately measure pupillary distance and segment height using the frame's built-in gridlines.
Solution Approach 2:
The patent extracts the measurement function from separate professional measuring tools and embeds it directly into the eyewear frame structure itself. By taking out the measurement capability from specialized equipment and integrating it into the product, the system eliminates the need for professional optical staff while enabling retailers to dispense prescription frames with the same measurement accuracy previously requiring trained professionals.
4Measurement precision
If separate measurements are taken for each eye using traditional tools, then measurement precision is maintained, but loss of time increases due to multiple measurement steps
Solution Approach 1:
The patent merges the measurement process for both eyes into a single simultaneous operation. When the eyewear frame is placed on the wearer's face, both horizontal (pupillary distance) and vertical (segment height) measurements for both eyes are captured at the same time through the integrated gridlines, eliminating the sequential measurement steps required by traditional tools and reducing total measurement time while maintaining individual measurement precision.
