Solution Overview

Problem

Laboratory technicians with little experience often struggle to effectively utilize the various functions of medical devices due to the complexity of operation manuals and limited access to training, leading to inefficient use of new functions.

Innovation Solution

A function recommendation system that includes an operation information recording unit, function information recording unit, and a recommended function calculation unit to suggest suitable functions based on the device's usage status, reducing the burden on users.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If operation manuals and training are provided to help users effectively utilize medical device functions, then user knowledge and function utilization improve, but the complexity and time burden on users increase

Engineering Contradiction:
Improvefunction knowledgeVSAvoidoperation manual complexity
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The system automatically analyzes operation logs and device status without requiring user intervention to study manuals. The recommendation engine self-serves by generating function suggestions based on accumulated operational data, eliminating the need for users to manually search through complex documentation.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system continuously monitors operation logs and provides feedback in the form of function recommendations. This closed-loop feedback mechanism allows users to improve their utilization of device functions over time without needing to study complex manuals, as the system adapts to their specific usage patterns and suggests relevant functions.

Inventive Principle:
Principle #23Feedback

2Adaptability or versatility

If comprehensive training and user meetings are organized to improve function utilization, then user expertise increases, but time and resource costs increase

Engineering Contradiction:
Improvefunction adaptabilityVSAvoidtraining time
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The system performs preliminary analysis of operation logs and device status in advance, preparing function recommendations before users need them. This eliminates the need for time-consuming training sessions, as users receive ready-to-apply suggestions based on pre-analyzed operational data.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

Users receive automated function recommendations without needing to attend training meetings or workshops. The system serves itself by analyzing operational data and generating suggestions, replacing the need for organized training events while still improving function adaptability.

Inventive Principle:
Principle #25Self-service

3Loss of information

If users manually study operation manuals to learn device functions, then function knowledge improves, but work burden and time consumption increase

Engineering Contradiction:
Improvefunction informationVSAvoidinformation access ease
Core Design Contradiction:
Loss of informationVSEase of operation

Solution Approach 1:

The system extracts only the relevant function information needed for each user's specific situation from the vast operation manual database. Instead of requiring users to study entire manuals, the system extracts and presents only the functions applicable to their current operational context.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The recommendation engine automatically retrieves and presents function information based on analyzed operation logs, eliminating the manual searching and studying process. Users simply receive tailored function suggestions without needing to access or study the actual operation manuals.

Inventive Principle:
Principle #25Self-service
