Spectacle-Type Electronic Device for Hands-Free Industrial Information Reporting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wearable devices used for job assistance and information reporting in industrial settings face challenges due to increased weight and size, which compromise their wearability and lead to higher manufacturing costs and system complexity.
Innovation Solution
A spectacle-type electronic device with an image display, light source, signal processor, and communication processor that projects virtual information within the wearer's line of sight, using a dimming-type white LED light source and reflection liquid crystal display, allowing for hands-free operation and efficient data transfer via short-range wireless communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the wearable device increases weight and size to report information more concretely, then the information reporting capability is improved, but the wearing property deteriorates and the device may be separated from the wearer
Solution Approach 1:
The patent replaces traditional mechanical display systems with a projection-based optical system. The wearable device uses an image display unit that projects images onto a screen positioned in the extension of the wearer's line of sight, eliminating the need for heavy conventional displays while maintaining information delivery capability
Solution Approach 2:
The patent transitions from two-dimensional screen displays to three-dimensional virtual image projection in the wearer's visual field. The screen is positioned at a specific location within the extension of the wearer's line of sight, creating a virtual display that appears to float in space without adding physical bulk to the device
2Loss of information
If the wearable device increases weight and size to report information more concretely, then the information reporting capability is improved, but the device complexity and manufacturing costs increase
Solution Approach 1:
The wearable device integrates multiple functions into a single compact unit: the image display unit serves both as a display device and as part of the projection system, while the communication unit handles both data transmission and reception. This multi-functionality reduces overall system complexity compared to separate specialized components
Solution Approach 2:
The patent uses optical projection to create a virtual copy of the display content in the wearer's visual field. Instead of physically transporting heavy display components, the system projects light patterns that replicate the visual information, effectively copying the display function into the wearer's line of sight
3Loss of information
If traditional display methods are used, then information can be displayed, but eye strain increases and work efficiency decreases
Solution Approach 1:
The patent positions the display screen in the extension of the wearer's line of sight, creating a virtual image that appears to float in the wearer's visual field rather than requiring the wearer to look down at a conventional display. This spatial repositioning reduces neck strain and eye fatigue by aligning the display with the natural line of sight
Solution Approach 2:
The patent introduces a projection screen as an intermediary between the image display unit and the wearer's eyes. The screen is positioned at a specific location within the extension of the wearer's line of sight, acting as a mediator that presents information in a visually comfortable position without requiring the wearer to change their natural viewing posture
