Solution Overview

Problem

Conventional multifunction apparatuses with scan functions are limited in portability and require the object to be scanned to be moved to a fixed device, restricting the ability to easily scan small items like business cards without the need for extensive movement.

Innovation Solution

A system comprising a display apparatus and an input apparatus with a scanner function, where the input apparatus includes a scanning unit, position detecting unit, and communication interface, allowing for the acquisition and transmission of scan images while enabling user control through a user interface, and the display apparatus processes and displays the scan images, including features like memory guides and velocity feedback to optimize scanning.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a multifunction apparatus is fixedly installed to perform scanning, then scanning function is available, but portability is limited and objects must be moved to the apparatus

Engineering Contradiction:
ImproveportabilityVSAvoidscanning system complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

Instead of moving the object to be scanned to a fixed scanner, the patent inverts the approach by making the scanner itself movable. The portable scanning apparatus can be freely moved to scan objects at their location, eliminating the need to transport objects to a fixed scanning position.

Inventive Principle:
Principle #13The other way round (Inversion)

Solution Approach 2:

The patent transforms the scanner from a static fixed installation to a dynamic portable device. The scanning apparatus incorporates positioning mechanisms and can be moved to different locations, changing from a stationary system to a mobile system that adapts to various scanning needs.

Inventive Principle:
Principle #15Dynamics

2Ease of operation

If the scanning apparatus is made portable and movable, then ease of operation improves, but measurement precision may deteriorate due to movement

Engineering Contradiction:
ImproveportabilityVSAvoidscan image quality
Core Design Contradiction:
Ease of operationVSMeasurement precision

Solution Approach 1:

The patent incorporates a position detecting unit that provides feedback on the apparatus's location and movement state. This feedback mechanism allows the system to compensate for movement effects and maintain scanning precision by adjusting parameters based on real-time position information.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The patent replaces traditional mechanical scanning systems with software-based image processing and stitching techniques. Multiple images captured during movement are computationally combined to create high-quality scan results, substituting mechanical precision requirements with digital processing capabilities.

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

3Productivity

If real-time feedback and processing are implemented, then scanning efficiency improves, but device complexity increases

Engineering Contradiction:
Improvescanning efficiencyVSAvoidprocessing system complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent integrates multiple functions into a single portable apparatus: image capture, position detection, real-time processing, and result display. This multi-functional integration achieves scanning efficiency without proportionally increasing overall system complexity by combining functions in one device.

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

Solution Approach 2:

The system performs automatic image stitching, processing, and quality assessment without requiring manual intervention. The apparatus autonomously handles the complexity of real-time processing, providing efficient scanning results while minimizing user burden despite the underlying system complexity.

Inventive Principle:
Principle #25Self-service
