Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If paper documents are used, then accessibility and durability are improved, but searchability and ease of duplication are worsened

Engineering Contradiction:

Improvedocument accessibilityVSAvoidsearch efficiency

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

The patent creates a digital copy of the paper document that can be searched electronically. The system captures an image of the paper document and processes it to create a searchable digital representation, allowing users to search the digital copy while the original paper document remains accessible and durable.

Inventive Principle:

Principle #26Copying

Solution Approach 2:

The patent introduces a digital intermediary layer between the paper document and the user. This digital copy acts as a mediator that provides searchability and ease of duplication, while the original paper document maintains its physical advantages of accessibility and durability.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Productivity

If electronic documents are used, then searchability and ease of duplication are improved, but accessibility and durability are worsened

Engineering Contradiction:

Improvesearch efficiencyVSAvoiddocument accessibility

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The patent merges the advantages of both paper and electronic documents into a unified system. The paper document provides physical accessibility and durability, while the digital copy provides electronic searchability and ease of duplication. Both formats coexist and complement each other.

Inventive Principle:

Principle #5Merging (Combining)

3Adaptability or versatility

If handheld capture devices are added, then integration of paper and digital documents is improved, but device complexity is worsened

Engineering Contradiction:

Improvedocument integrationVSAvoidsystem complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The handheld device is designed to perform multiple functions: capturing images of paper documents, processing the images to create digital copies, and enabling search and retrieval operations. This multi-functionality reduces the need for separate devices for each task.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system includes automatic processing capabilities that reduce manual intervention. The handheld device automatically captures, processes, and indexes document images, and the system automatically manages the digital copies and search operations.

Inventive Principle:

Principle #25Self-service
