Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If the size of the display device is limited for wearability, then the device becomes more portable and wearable, but the touch input accuracy and minute control become difficult
Solution Approach 1:
The patent introduces lateral displays at the side surfaces of the display unit, transitioning from a single front display to a multi-dimensional display arrangement. This allows users to interact with content from multiple angles and perspectives, improving touch input accuracy and control while maintaining a compact form factor suitable for wearability.
2Length of moving object
If the display screen size is limited, then the device remains portable and wearable, but the ability to display multiple screens and images is reduced
Solution Approach 1:
The display unit is segmented into multiple independent display regions including a front display and four lateral displays at the side surfaces. Each display can independently show different images or content, enabling multi-screen display functionality while maintaining a compact overall device size suitable for portable wearables.
Solution Approach 2:
By adding lateral displays at the side surfaces of the display unit, the patent creates a three-dimensional display arrangement that allows simultaneous presentation of multiple images from different viewpoints. This dimensional expansion enables enhanced versatility and adaptability without increasing the device's footprint.
3Adaptability or versatility
If multiple lateral displays are added to show multiple viewpoints, then the display versatility and information content increase, but the device complexity increases
Solution Approach 1:
The lateral displays are integrated into the display unit structure, allowing the same physical component to serve multiple functions: displaying images from different viewpoints, providing touch input from multiple angles, and presenting information in three-dimensional space. This multi-functionality reduces the need for separate components, thereby managing device complexity while enhancing versatility.

AI summary
A portable display terminal according to an exemplary embodiment of the invention includes: a display unit configured to display an image and a mounting unit on which the display unit is mounted. The display unit includes a front display at a front surface of the display unit, and a first lateral display, a second lateral display, a third lateral display and a fourth lateral display at respective side surfaces of the display unit adjacent to the front display. A first image representing a front surface of a displayed object is displayed at the front display, a second image representing a lower side of the displayed object with respect to the first image is displayed at the first lateral display, a third image representing a first lateral side of the displayed object with respect to the first image is displayed at the second lateral display, a fourth image representing an upper side of the displayed image with respect to the first image is displayed at the third lateral display, and a fifth image representing a second lateral side of the displayed image opposite to the first lateral side with respect to the first image is displayed at the fourth lateral display.
