Solution Overview

Problem

There is a shortage of effective educational materials and tools for visually impaired individuals to learn braille, particularly for those with undeveloped fingertip sensitivity, as actual printed braille is small and difficult to handle.

Innovation Solution

A braille teaching material is developed with magnetic parts attached to raised dots, allowing a teaching tool to be detachably attached via magnetic force, facilitating learning by providing tactile and visual cues, including an information section with uneven shapes and stroke guidance, and incorporating NFC tags for voice guidance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If actual printed braille is used for teaching, then the material is simple and easy to manufacture, but beginners with undeveloped fingertip sensitivity cannot effectively learn braille

Engineering Contradiction:
Improvesimplicity of teaching materialVSAvoiddetectability of braille dots
Core Design Contradiction:
Ease of manufactureVSEase of operation

Solution Approach 1:

The patent applies local quality by providing magnetic parts only at specific braille dot positions rather than uniformly across the entire material. This allows the teaching material to enhance tactile detectability precisely where needed (at braille dot locations) while maintaining simplicity elsewhere in the material structure.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent introduces magnetic parts as an intermediary element between the braille dots and the learner's fingertips. These magnetic parts create a magnetic field that enhances the tactile sensation when learners approach or touch the braille dots, making them more detectable for beginners with undeveloped fingertip sensitivity.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If magnetic parts are added to braille dots to enhance detectability, then beginners can effectively learn braille, but the manufacturing process becomes more complex

Engineering Contradiction:
Improvedetectability of braille dotsVSAvoidstructure of teaching material
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent segments the teaching material into distinct functional components: the base braille material and the magnetic parts. This segmentation allows each component to be optimized independently - the braille material maintains its simple printed structure while magnetic parts are strategically added only where needed, rather than making the entire material complex.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The magnetic parts are applied locally only at braille dot positions rather than uniformly across the entire teaching material. This localized application enhances detectability where needed while minimizing the overall complexity and material usage.

Inventive Principle:
Principle #3Local quality

3Ease of operation

If magnetic parts are provided at all dot positions, then all dots can be detected, but the cost and complexity increase unnecessarily

Engineering Contradiction:
Improvedetectability of braille dotsVSAvoidamount of magnetic material
Core Design Contradiction:
Ease of operationVSQuantity of substance

Solution Approach 1:

The patent applies magnetic parts selectively only at raised dot positions where tactile detection is needed, rather than at all dot positions including non-raised dots. This localized approach provides enhanced detectability for braille learning while minimizing the quantity of magnetic material required.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent implements partial action by providing magnetic enhancement only where necessary (at raised braille dots) rather than applying it universally to all dots. This partial application is sufficient to achieve the learning objective without the excessive cost and complexity of universal application.

Inventive Principle:
Principle #16Partial or excessive action
