Solution Overview
Problem
Athletes and individuals engaged in physical activities face challenges in safely using electronic devices without removing their hands from their activity or diverting their focus, as existing heads-up display systems for glasses are not adequately designed for hands-free operation and ambient light interference.
Innovation Solution
A heads-up display (HUD) system integrated into glasses, featuring an adjustable display arm, ultraviolet-blocking materials, and a modular design that balances weight, allowing for hands-free operation and reduced ambient light interference, with components such as a processor, camera, and user interface for navigation and image display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a cell phone display clips onto eyeglasses, then a display function is provided, but the device is not suitable for hands-free operation during physical activity and is susceptible to ambient light interference
Solution Approach 1:
The display system is segmented into separate functional components: a display unit mounted on the glasses frame, a separate processing unit, and a camera module. This segmentation allows each component to be optimized for its specific function, with the display unit specifically designed for hands-free viewing during physical activity.
Solution Approach 2:
The patent converts the harmful effect of ambient light by introducing UV-blocking materials and polarizing filters that selectively block harmful ultraviolet radiation and reduce glare from ambient light sources, while maintaining visibility of the display content. The display is positioned and angled to minimize direct exposure to ambient light during athletic activities.
2Adaptability or versatility
If display components are added to glasses, then display functionality is achieved, but weight balance and comfort are compromised
Solution Approach 1:
The patent employs counterbalancing weights integrated into the temples or frame of the glasses to offset the weight of the display unit and other electronic components. This counterweight system maintains the center of gravity of the glasses, preventing them from sliding or feeling unbalanced during physical activity.
Solution Approach 2:
The display unit is positioned in a three-dimensional space optimized for viewing during physical activity, mounted on the frame rather than the lens, and angled to provide optimal viewing geometry. This spatial arrangement allows the display to be integrated without significantly increasing the overall footprint or discomfort of the glasses.
3Illumination intensity
If the display is made brighter to overcome ambient light, then visibility improves, but energy consumption increases
Solution Approach 1:
The display operates with periodic updating rather than continuous refresh, and the backlight is activated only when needed based on ambient light detection. The system uses duty cycling to reduce average power consumption while maintaining adequate brightness during active use periods.
Solution Approach 2:
The display brightness is dynamically adjusted based on ambient light conditions detected by sensors. The system changes the luminance parameter adaptively, increasing brightness only when necessary to overcome ambient light interference, and reducing brightness in lower light conditions to conserve energy.
