Solution Overview

Problem

Existing systems require users to confirm scoring results using IT terminals, which can be cumbersome, especially for minors, and do not allow easy confirmation of paper-based test scores.

Innovation Solution

A system comprising a multifunction peripheral (MFP) that reads filled-in answer sheets, transmits data to a server for scoring, and prints the scoring results, enabling easy confirmation of test results without the need for IT terminals.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If users use IT terminals to confirm scoring results, then scoring results can be processed and displayed, but the process becomes cumbersome and inconvenient

Engineering Contradiction:
Improveease of confirming scoring resultsVSAvoidcomplexity of using IT terminals
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent combines the scoring result confirmation function with the existing answer sheet printing function in the multifunction peripheral. The MFP integrates reading, scoring, and printing operations into a single device, eliminating the need for separate IT terminals and simplifying the user workflow for confirming scoring results.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The multifunction peripheral performs scoring result confirmation automatically without requiring users to manually access external IT terminals. The system self-services by reading the answer sheet, transmitting data to the server, receiving scoring results, and printing them directly on the answer sheet, thereby reducing operational complexity for users.

Inventive Principle:
Principle #25Self-service

2Object-affected harmful factors

If paper-based tests are used, then vision can be protected and hand-writing practice is maintained, but scoring result confirmation becomes difficult

Engineering Contradiction:
Improveprotection of vision and hand-writing practiceVSAvoidease of confirming paper test scores
Core Design Contradiction:
Object-affected harmful factorsVSEase of operation

Solution Approach 1:

The system provides immediate feedback by automatically transmitting the scanned answer sheet data to the scoring server, receiving the scoring results, and printing them directly on the answer sheet. This closed-loop feedback mechanism maintains the simplicity of paper-based testing while adding automated scoring result confirmation, protecting vision and hand-writing practice without compromising ease of score verification.

Inventive Principle:
Principle #23Feedback

3Productivity

If automated scoring systems are implemented, then scoring efficiency is improved, but system complexity increases

Engineering Contradiction:
Improvescoring efficiencyVSAvoidcomplexity of automated scoring system
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The multifunction peripheral is designed to perform multiple functions including document reading, data transmission, scoring result reception, and printing. By making the MFP universal and multi-functional, the patent consolidates the automated scoring system into a single device, improving scoring efficiency while minimizing the increase in system complexity through existing hardware capabilities.

Inventive Principle:
Principle #6Universality (Multi-functionality)
