Solution Overview

Problem

Conventional methods for reading books are inconvenient as they do not allow for a suitable viewing angle, leading to discomfort for the reader.

Innovation Solution

An electronic device equipped with a display screen, image capturing units, and a control unit that determines a suitable viewing angle by analyzing the relative distance between the reader's eye and the book, allowing the display screen to rotate to maintain an optimal viewing position.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the reader holds the book by hands and keeps the book standing, then the book can be read, but it results in inconvenience and discomfort for the reader

Engineering Contradiction:
Improvereading convenienceVSAvoidsupport structure complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent uses image capturing units to capture images of the book and eye, then uses image analysis to create a digital model of the reading scenario. This allows the system to determine viewing angles and adjust the display screen accordingly, replacing the need for manual book holding with an automated digital copying and analysis approach.

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The patent replaces the manual mechanical action of holding and positioning a book with an automated system that uses image capturing units, image analysis units, and a control unit to determine optimal viewing angles and adjust the display screen position automatically.

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

2Ease of operation

If the display screen rotates to adjust viewing angle, then reading comfort is improved, but the device structure becomes more complex

Engineering Contradiction:
Improveviewing angle adjustmentVSAvoidpivot mechanism complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent makes the display screen dynamically adjustable through pivotal connection, allowing it to rotate and change its angle relative to the main body. This dynamic adjustment is controlled by the control unit based on image analysis results, enabling the system to adapt to different reading scenarios and maintain optimal viewing angles.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent implements a feedback loop where the image capturing units continuously monitor the reader's eye position and the book position, the image analysis unit processes this information to determine the current viewing angle, and the control unit adjusts the display screen angle accordingly to maintain optimal reading conditions.

Inventive Principle:
Principle #23Feedback

3Measurement precision

If the image capturing units and analysis unit are added, then the viewing angle can be optimized, but the device complexity increases

Engineering Contradiction:
Improveeye position detection accuracyVSAvoidimage processing system complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent introduces an image analysis unit as an intermediary between the image capturing units and the control unit. This intermediary component processes the captured images to extract relevant information about eye position and book position, then provides this processed information to the control unit for decision-making, simplifying the overall system architecture.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent uses image capturing units to create digital copies of the physical reading scenario, including the book position and eye position. This digital copying allows for precise measurement and analysis without physically interfering with the reading process, enabling accurate determination of viewing angles.

Inventive Principle:
Principle #26Copying

AI summary

The electronic device includes a main body, a display screen, a first block plate, a first image capturing unit, a second image capturing unit, an image analysis unit and a control unit. The first image capturing unit is used for capturing a book image of the book and a first eye image of an eye. The second image capturing unit is used capturing a second eye image of the eye. The image analysis unit is used for determining a relative distance between the eye and the main body according to the first eye image and the second eye image and a book size of the book according to the book image. The control unit is used for determining a suitable viewing angle and controlling the display screen to rotate, such that a viewing angle at the book viewed by the eye is substantially equal to the suitable viewing angle.
