Solution Overview

Problem

Traditional homework assessment methods are inefficient, lack customization, and fail to effectively monitor academic progress due to manual processing and limited AI integration, with existing electronic solutions primarily focusing on multiple-choice questions and facing challenges in handling diverse question types and user experience.

Innovation Solution

A method and system for automatically identifying and generating answer regions for handwritten questions in electronic assignments, utilizing a question determination module, attribute information obtaining module, and region generation module to create tailored answer areas, integrated with a processing system for electronic assignments and a user portal, enabling efficient and personalized learning management.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If automated marking methods are used for multiple-choice questions, then marking efficiency is improved, but applicability is limited to only multiple-choice question types

Engineering Contradiction:
Improvemarking efficiencyVSAvoidapplicability to diverse question types
Core Design Contradiction:
ProductivityVSAdaptability or versatility

Solution Approach 1:

The system is designed to handle multiple question types (multiple-choice, fill-in-the-blank, short answer, essay) through a unified electronic assignment platform. The region generation module can create different types of answer regions (selection areas, text input fields, handwriting areas) based on question attributes, making the system universally applicable to diverse question types while maintaining automated processing capabilities.

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

2Adaptability or versatility

If paper-based workbooks are used for homework assessment, then all question types can be accommodated, but management efficiency deteriorates due to manual processing

Engineering Contradiction:
Improvesupport for all question typesVSAvoidmanagement efficiency
Core Design Contradiction:
Adaptability or versatilityVSProductivity

Solution Approach 1:

The system replaces the mechanical paper-based workflow with an electronic digital system. Teachers can create, distribute, collect, and grade assignments electronically through the platform. The automated region generation and marking capabilities eliminate manual paper handling, printing, and physical collection processes while maintaining the ability to handle diverse question types through digital interfaces.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Ease of operation

If students capture photos of their answers for upload, then answer collection is enabled, but user experience deteriorates due to time consumption and inconvenience

Engineering Contradiction:
Improveanswer collection capabilityVSAvoidtime consumption for photo capture and upload
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The system provides self-service functionality where the answer region is automatically generated and prepared within the electronic assignment interface. Students can directly input answers in the pre-configured regions without needing to capture photos externally. The system handles the entire answer collection process automatically, eliminating the manual photo capture and upload steps while improving user experience.

Inventive Principle:
Principle #25Self-service

4Adaptability or versatility

If manual marking of paper assignments is used, then all answer types can be assessed, but time consumption increases significantly

Engineering Contradiction:
Improveassessment capability for all answer typesVSAvoidtime consumption for manual marking
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The system implements automated feedback mechanisms where student answers are automatically processed and evaluated based on the question type. For objective questions, automated marking provides immediate feedback. For subjective questions, the system facilitates efficient teacher review through electronic interfaces. This automated feedback loop significantly reduces the time required for assessment while maintaining comprehensive evaluation capabilities across all question types.

Inventive Principle:
Principle #23Feedback

AI summary

Provided in the present disclosure are a question-answering area acquisition method and system, an electronic assignment processing method and system, and a device and a medium. The acquisition method comprises: determining a question to be processed; acquiring question attribute information of said question; on the basis of the question attribute information, determining whether said question is a handwriting question type; and if so, generating in a first preset blank canvas a handwriting question-answering area matching said question. In the present disclosure, a handwriting question in an electronic assignment can be automatically identified, a corresponding handwriting question-answering area can be automatically generated, manual intervention is not needed during the process, and the process is fully automatically implemented, thereby effectively improving the electronization level of the electronic assignment; the handwriting question-answering area supports the display of content after different operation layers are stacked, such that the interaction between different users is more convenient and efficient; and live broadcasting, recorded broadcasting, etc., of writing trajectories of different users in the area are also supported. Therefore, the intelligent solution provides a practical and feasible technical route for catering to students' individual learning needs on a large scale, and for improving the overall quality of teaching.
