Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users viewing multiple screens or large displays often experience outer edges outside their field of view, necessitating unnecessary head movement to fully view content, and existing technologies do not effectively optimize the field of view.
Innovation Solution
A dynamic screen that adjusts its curvature based on the distance to the viewer using sensors, such as Time of Flight sensors, and an actuator system with self-locking worm gears to maintain the desired curvature without continuous power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the screen uses a fixed flat configuration, then the device complexity is low, but the field of view is limited and outer edges are outside user FOV
Solution Approach 1:
The screen transitions from a fixed flat configuration to a dynamically adjustable curved configuration. The display panel can change its curvature radius based on viewing distance detected by sensors, allowing the screen to adapt between flat and curved states to optimize field of view for different usage scenarios.
Solution Approach 2:
The physical parameter of the screen curvature radius is changed dynamically. By adjusting the curvature radius from infinity (flat) to a finite value (curved), the screen expands the field of view to include outer edges within the user's visual range.
2Adaptability or versatility
If the screen curvature is continuously adjusted using active actuators, then the field of view is optimized, but continuous power consumption increases
Solution Approach 1:
Instead of continuous adjustment, the system uses periodic sensing (distance sensors detect viewer position) followed by discrete curvature adjustments. The screen maintains its curvature state until a change in viewing distance is detected, eliminating continuous power consumption while still optimizing field of view.
Solution Approach 2:
The system uses passive distance sensors to detect viewer position and triggers curvature adjustment only when needed. The screen serves itself by automatically adjusting to the appropriate curvature based on detected viewing conditions without requiring continuous external control power.
3Adaptability or versatility
If the screen adjusts curvature dynamically, then the field of view is optimized for different distances, but the device complexity increases
Solution Approach 1:
A curvature control mechanism acts as an intermediary between the display panel and the housing. This mechanism includes distance sensors, a controller, and actuation elements that work together to adjust the panel's curvature radius, adding functionality while managing complexity through modular design.
