Solution Overview

Problem

Young practitioners and beginners in martial arts, especially children and those with disabilities, face difficulties in learning precise hand placement techniques due to lack of visualization, leading to slow learning and potential abandonment of the sport.

Innovation Solution

An educational judogi with color-coded and alphanumeric markings on the sleeves and lapels to clearly indicate grip zones, allowing practitioners to easily visualize and perform techniques with precision.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If traditional judogi without markings are used, then the garment maintains simplicity and traditional appearance, but practitioners struggle to visualize and memorize precise hand placement areas

Engineering Contradiction:
Improvevisualization of grip areasVSAvoidjudogi marking system
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The patent applies color coding to different grip areas on the judogi, with each color representing a specific hand placement zone. This visual differentiation helps practitioners quickly identify and memorize the precise locations for various techniques without complex textual markings.

Inventive Principle:
Principle #32Color changes

Solution Approach 2:

The judogi is divided into multiple marked zones on the sleeves and lapels, with each zone corresponding to a specific grip area. This segmentation allows practitioners to focus on and memorize individual hand placement areas separately, making the overall learning process more manageable.

Inventive Principle:
Principle #1Segmentation

2Measurement precision

If practitioners spend extensive time repeating movements to learn techniques, then precision in hand placement is achieved, but the learning process becomes physically and psychologically difficult and time-consuming

Engineering Contradiction:
Improveprecision of hand placementVSAvoidlearning duration
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The judogi markings are applied beforehand to indicate the precise hand placement areas before the practitioner begins practicing. This preliminary visual information allows learners to understand the correct technique from the start, reducing the time needed for repetitive trial-and-error practice.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The color-coded markings provide immediate visual feedback to practitioners during practice, showing them whether their hand placement is correct or needs adjustment. This feedback mechanism accelerates the learning process by eliminating unnecessary repetitions and guiding precise technique acquisition.

Inventive Principle:
Principle #23Feedback

3Adaptability or versatility

If the same marking system is used for all practitioners, then the judogi design remains simple, but it fails to accommodate different learning needs of children, beginners, and people with disabilities

Engineering Contradiction:
Improveadaptability to different learnersVSAvoidmarking system variety
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent employs different marking styles and color intensities in different zones of the judogi, allowing practitioners to focus on specific areas that are most relevant to their current learning objectives. This localized differentiation can be adapted to suit the needs of different learner groups without requiring entirely separate marking systems.

Inventive Principle:
Principle #3Local quality
