Spectacle Lens Design Using Character-Size Sensitivity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing spectacle lens designs do not adequately consider individual wearer's sensitivity to character size, leading to suboptimal vision correction and comfort.
Innovation Solution
A system and method that acquires and utilizes sensitivity information related to a wearer's sensitivity to character size to design and manufacture customized spectacle lenses, incorporating this information into the lens design process through a comprehensive ordering and manufacturing system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If standard spectacle lens designs are used, then manufacturing and ordering processes are simple, but vision correction and comfort are suboptimal for individual wearers
Solution Approach 1:
The patent applies parameter changes by incorporating sensitivity information about character size into the lens design parameters. This allows the lens design to be adjusted based on individual wearer characteristics, improving vision correction quality while maintaining a manageable design process through systematic parameter integration
Solution Approach 2:
The patent implements preliminary action by acquiring sensitivity information about character size before the lens design process begins. This pre-acquired information is then integrated into the design parameters, enabling customized lens design that accounts for individual wearer needs from the outset
2Ease of operation
If customized lens design based on sensitivity information is implemented, then vision correction and comfort are enhanced, but ordering and manufacturing processes become more complex
Solution Approach 1:
The patent applies universality by creating an ordering system that handles both standard and customized lens orders through a unified process. The sensitivity information acquisition module integrates seamlessly with existing ordering workflows, allowing the system to serve multiple functions without requiring completely separate processes
3Measurement precision
If sensitivity information is integrated into lens design, then individualized vision correction is achieved, but measurement and data acquisition processes become more difficult
Solution Approach 1:
The patent implements self-service by enabling wearers to provide sensitivity information about their character size preferences through self-reporting or simple interactions with the ordering system. This approach reduces the burden on measurement processes while still achieving precise individualized data collection
