Modular Eyeglasses with Adjustable Interpupillary Distance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for temporary, properly fitting eyeglasses that match a wearer's current prescription during the time between receiving a prescription and obtaining finished glasses, as well as for temporary solutions during repairs or replacement, which existing technologies fail to address due to the challenges of proper fitment and the lack of immediate, cost-effective options.
Innovation Solution
The development of adjustable prescription eyeglasses with features such as adjustable interpupillary distance, temple lengths, and modular lens frames that can accept universal lenses, allowing for secure and proper fitment without the need for tools or professional assistance, accommodating a wide range of prescriptions and facial features.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If traditional eyeglasses are used, then prescription correction is provided, but the time delay from prescription issuance to finished glasses delivery (weeks to a month) causes safety and health risks
Solution Approach 1:
The eyeglasses are divided into separate modular components: temple members with adjustable lengths, a bridge member with adjustable width, and lens holders that can be independently positioned. This segmentation allows rapid assembly from pre-manufactured parts, eliminating the weeks-long traditional manufacturing process while ensuring proper fit and prescription alignment through adjustable mechanisms.
Solution Approach 2:
Multiple temple members with different lengths and bridge members with different widths are pre-manufactured and provided in a kit. These components are prepared in advance with various specifications to match different facial dimensions, allowing immediate selection and assembly when a prescription is received, thus eliminating the traditional manufacturing delay.
2Ease of operation
If custom-fitted eyeglasses are made, then proper fitment is achieved, but the process requires professional fitment specialists and extensive adjustment time
Solution Approach 1:
The eyeglasses incorporate dynamic adjustment mechanisms allowing users to modify temple lengths, bridge width, and lens holder positions after assembly. This enables post-purchase customization without requiring professional fitment specialists, as users can independently adjust the glasses to achieve optimal comfort and fit for their facial dimensions.
Solution Approach 2:
The adjustable mechanisms are designed for user-friendly operation, enabling wearers to perform their own fitment adjustments without professional assistance. The modular components and adjustment features allow individuals to independently customize the eyeglasses to their specific needs, eliminating the need for costly and time-consuming professional adjustment services.
3Adaptability or versatility
If adjustable mechanisms are added to eyeglasses, then universal fitment is achieved, but device complexity increases
Solution Approach 1:
The adjustment system is segmented into independent, simple mechanisms: temple members that slide in and out at fixed intervals, bridge members that adjust width through modular positioning, and lens holders that move along predetermined paths. Each adjustment feature operates independently with simple insertion/removal actions, avoiding complex multi-component adjustment systems while achieving universal fitment across diverse facial dimensions.

AI summary
The present disclosure provides for universally-fitting prescription eyeglasses and kits and methods of use thereof. The prescription eyeglasses advantageously provide for one or more of an adjustable width, and adjustable interpupillary distance, and adjustable temple lengths. In various embodiments, the adjustable eyeglasses may provide for asymmetric arrangements of components for users having asymmetric facial features. The adjustable eyeglasses can accommodate lenses of varying prescription and kits may include sets of replaceable lenses to accommodate prescription needs for patients without lengthy custom lens fitting.
