Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The high incidence of myopia among students due to increased use of electronic products poses a significant social problem, as existing myopia prevention methods are often inconvenient, expensive, and ineffective.
Innovation Solution
An anti-myopia paper sheet is developed with graphic color blocks of light yellow, light green, or light blue printed across its writing area, featuring a specific wavelength range of reflected light, reduced reflectance factor, and controlled color purity to reduce eye strain and prevent myopia.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional myopia prevention methods (instruments and medicines) are used, then myopia prevention effect is achieved, but convenience and cost are poor
Solution Approach 1:
The patent uses ordinary printing paper with printed color blocks instead of expensive medical instruments or medicines. The paper sheet is a simple, inexpensive, disposable-like product that provides myopia prevention through its optical properties rather than through complex medical mechanisms.
Solution Approach 2:
The patent changes the optical parameters of the paper surface by printing specific color blocks with controlled color purity (6%-18%), brightness (58%-72%), and reflected light wavelength (538nm-590nm). These parameter changes create the myopia prevention effect without requiring complex devices.
2Object-affected harmful factors
If page reflectance factor is reduced by increasing surface roughness, then visual fatigue is alleviated, but myopia prevention effect is insufficient
Solution Approach 1:
Instead of merely increasing surface roughness to reduce reflectance, the patent uses color blocks with specific color purity (6%-18%) and reflected light wavelength (538nm-590nm). The color properties are precisely controlled to achieve both reduced visual fatigue and improved myopia prevention effect.
Solution Approach 2:
The patent optimizes multiple optical parameters simultaneously: color purity (6%-18%), brightness (58%-72%), and reflected light wavelength (538nm-590nm). This multi-parameter optimization achieves better myopia prevention than simply increasing surface roughness.
3Illumination intensity
If bright white paper is used for writing, then reading comfort is improved, but reflected light stimulation to eyes is excessive
Solution Approach 1:
The patent replaces bright white paper with color blocks having color purity of 6%-18% and reflected light wavelength of 538nm-590nm. This color transformation reduces the excessive stimulation to eyes while maintaining adequate reading comfort through controlled brightness (58%-72%).
Solution Approach 2:
The patent adjusts the brightness parameter to 58%-72% and controls the reflected light wavelength to 538nm-590nm, finding an optimal balance between reading comfort and eye protection that is superior to traditional bright white paper.
Applied Scientific Principles

AI summary
Provided is an anti-myopia paper sheet capable of effectively preventing eyestrain during reading or writing and reducing a reflectance factor of page reflected light, belonging to the field of stationery products. A number of graphic color blocks are printed all over a printed area for writing of the paper sheet, and each graphic color block is a graphic color block combination of any two colors of light yellow, light green, or light blue. A wavelength of reflected light in the printed area ranges from 538 nm to 590 nm, the brightness ranges from 58% to 72%, and a reflectance factor at 400 nm ranges from 48% to 60%. A page in the printed area has color purity ranging from 6% to 18%. The stimulation of full-frequency light to eyes is effectively prevented, and thus the myopia prevention is achieved.
