Head-Mounted Display System for Multi-Window Expansion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display systems face limitations in displaying a large number of windows without increasing the size of the display area, particularly in applications like machining tools where space is constrained and costs need to be managed.
Innovation Solution
A display system that combines a first display in an electronic apparatus with a head-mounted display device featuring a second display, utilizing a display destination selector and window selector to determine which display to use for each window, with detectors to adjust the position and orientation of the second display to avoid blocking the view of the first display and optimize the viewing experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a plurality of LCDs is used to increase the number of contents displayed on the windows, then the number of displayed contents increases, but the area in which these displays are placed increases
Solution Approach 1:
The patent introduces a head-mounted display device that adds a third dimension to the display system. Instead of expanding the display area horizontally with multiple LCDs, the system utilizes the vertical dimension by placing a second display on the user's head, allowing multiple windows to be displayed across different spatial planes without increasing the footprint of the main display area.
Solution Approach 2:
The display system is segmented into two distinct display devices: a first display (LCD) for primary information and a second display (head-mounted) for additional windows. This segmentation allows the system to distribute display content across multiple devices rather than requiring a single large display area, thus increasing the number of displayed contents without proportionally increasing the main display area.
2Quantity of substance
If the second display is positioned to display more windows, then the number of displayed contents increases, but the view of the first display may be blocked
Solution Approach 1:
The head-mounted display device is designed with dynamic positioning capabilities, allowing the second display to be adjusted to different positions and orientations. This dynamic adjustment enables the user to optimize the viewing angle and position of the second display relative to the first display, ensuring that additional windows can be displayed without blocking the view of the primary display.
Solution Approach 2:
The system assigns different display devices to different functional roles: the first display (LCD) is optimized for primary information display at a fixed position, while the second display (head-mounted) is positioned to provide supplementary information. This local quality differentiation allows each display to serve its specific purpose without interfering with the other's primary function.

AI summary
Provided is a display system capable of displaying the contents of a larger number of windows. In this display, an operator wears a head-mounted display device on his/her head, a first display is on the front side, and the eyes of the operator is directed to the first display. With the head-mounted display device, the operator can see an enlarged image on the right side by a right-side display unit and can see an enlarged image on the left side by a left-side display unit.
