Solution Overview

Problem

Existing methods for determining lenses for spectacles or contact lenses fail to adequately address the discomfort issues related to visual acuity correction and trunk balance.

Innovation Solution

A method that involves measuring the load balance of a subject, including left and right, front and back, and twist, to determine the appropriate power and type of lens for spectacles or contact lenses, ensuring both visual acuity correction and trunk balance maintenance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If lens power is determined based solely on visual acuity measurement, then visual correction is achieved, but trunk balance and comfort are compromised

Engineering Contradiction:

Improvevisual acuity correctionVSAvoidtrunk balance and comfort

Core Design Contradiction:

Measurement precisionVSEase of operation

Solution Approach 1:

The lens determination method integrates multiple measurement functions (visual acuity, load balance, posture) into a single comprehensive evaluation system. The lens is designed to simultaneously correct visual defects and maintain trunk balance, making the optical device multi-functional rather than single-purpose.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The method changes the parameters used for lens determination from solely visual acuity to include load balance (left-right, front-back) and posture parameters. This parameter expansion allows the lens prescription to account for biomechanical factors affecting trunk balance and comfort.

Inventive Principle:

Principle #35Parameter changes

2Measurement precision

If traditional visual function measurement is used, then lens power can be calculated, but discomfort in eyes and body persists

Engineering Contradiction:

Improvevisual function measurementVSAvoiddiscomfort in eyes and body

Core Design Contradiction:

Measurement precisionVSObject-affected harmful factors

Solution Approach 1:

The method incorporates feedback from load balance measurements (using foot pressure sensors or similar devices) and posture analysis into the lens determination process. This feedback loop allows continuous adjustment of lens parameters to eliminate discomfort while maintaining visual correction.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The patent introduces intermediary measurements of load balance and posture as mediating factors between visual acuity and lens prescription. These intermediary parameters serve as bridges that connect optical correction with biomechanical comfort.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Device complexity

If only visual acuity is measured, then lens determination is simple, but comprehensive comfort and balance are not achieved

Engineering Contradiction:

Improvemeasurement process simplicityVSAvoidoverall comfort and balance

Core Design Contradiction:

Device complexityVSEase of operation

Solution Approach 1:

The comprehensive measurement process is segmented into distinct modules: visual acuity measurement, load balance measurement (left-right, front-back), and posture measurement. Each module independently collects specific data, which is then integrated to determine the final lens prescription, making the complex process manageable and systematic.

Inventive Principle:

Principle #1Segmentation
