Arcuate Display Positioning for Consistent Viewing Angle
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional displays have a limited effective viewing angle, requiring viewers to maintain a specific position to achieve optimal viewing, which can lead to fatigue, especially in applications like endoscopic surgery where prolonged viewing is necessary.
Innovation Solution
A display position adjusting method and apparatus using an arcuate bracket with interconnected rods and motors, controlled by a processor, to adjust the display's position based on viewer angle changes, ensuring the display plane remains perpendicular to the viewer's line of sight.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the display position is fixed, then the device complexity is reduced, but the viewing effect deteriorates when the viewer changes position or angle
Solution Approach 1:
The display position adjusting mechanism transforms the fixed display into a dynamic system that can automatically adjust its position and orientation based on the viewer's head movements. The arcuate bracket with motors enables the display to move along curved paths and rotate to maintain optimal viewing angles, resolving the contradiction between fixed simplicity and dynamic viewing comfort
Solution Approach 2:
The system incorporates sensors to detect the viewer's head position and angle, providing real-time feedback to the control unit. This feedback loop enables the display to automatically adjust its position to maintain the optimal viewing angle, solving the contradiction by making the system responsive to viewer movements without requiring manual intervention
2Reliability
If the viewer maintains a fixed posture to achieve optimal viewing angle, then the viewing effect is improved, but the viewer experiences body and neck fatigue during prolonged viewing
Solution Approach 1:
The dynamic display adjustment system allows the viewer to change posture freely while the display automatically repositions itself to maintain the optimal viewing angle. This eliminates the need for the viewer to maintain a fixed, fatiguing posture, resolving the contradiction between viewing quality and viewer comfort during prolonged use
Solution Approach 2:
The display system serves itself by automatically adjusting its position in response to viewer movements, eliminating the need for the viewer to manually reposition the display or maintain rigid posture. The system compensates for viewer fatigue by taking on the adjustment task, resolving the contradiction between maintaining viewing quality and reducing physical strain
3Reliability
If the display is adjusted manually to change viewing angle, then the viewing effect can be improved, but the ease of operation deteriorates due to frequent manual adjustments
Solution Approach 1:
The automatic adjustment system uses sensors to detect viewer head position and angle, providing real-time feedback that triggers automatic display repositioning. This eliminates the need for frequent manual adjustments, resolving the contradiction by making the system responsive to viewing angle changes without requiring viewer intervention
Solution Approach 2:
The display system performs self-adjustment based on detected viewer position, eliminating the need for manual operation. The system serves itself by automatically maintaining optimal viewing conditions, resolving the contradiction between achieving good viewing effects and maintaining ease of operation
