Solution Overview

Problem

Existing eyeglasses lens machining devices face challenges in accurately determining the appropriate replacement time for consumable items such as cups, whetstones, and other components, relying on user estimation based on experience rather than precise data.

Innovation Solution

The eyeglasses lens machining device incorporates a system to acquire period information, machining information, and recommendation information to predict the optimal replacement time for consumable items using a CPU to analyze usage data and recommend timely replacements.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If replacement time is estimated based on user experience, then operational flexibility is maintained, but measurement precision of replacement timing deteriorates

Engineering Contradiction:

Improvereplacement time determination accuracyVSAvoidsystem complexity

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The system implements feedback by continuously monitoring consumable item usage through the period information acquisition unit and machining information acquisition unit, then using this feedback data to predict and notify users of optimal replacement timing through the recommendation information acquisition unit and output unit

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The patent replaces the mechanical/manual method of estimating replacement time based on user experience with an automated information processing system that uses period information, machining information, and prediction algorithms to determine replacement timing objectively

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Productivity

If consumable items are replaced based on user estimation, then operational simplicity is maintained, but productivity deteriorates due to unexpected downtime

Engineering Contradiction:

Improveoperational efficiencyVSAvoiddowntime

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

The system performs preliminary action by predicting the optimal replacement time before the consumable item actually fails or becomes ineffective, allowing users to plan and execute replacements at convenient times rather than reacting to unexpected failures

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The machining device performs self-service by automatically monitoring its own consumable item usage and generating replacement recommendations, eliminating the need for manual tracking and experience-based estimation by operators

Inventive Principle:

Principle #25Self-service
