Adjustable Curved Display Mechanism for Immersive Forward Sound
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional curved display apparatuses have fixed curvature, which limits user preference and immersion, and suffer from degraded sound quality due to sound interference, making it difficult to accurately transfer sound and maintain acoustic immersion.
Innovation Solution
A display apparatus with a curvature variation device that allows the display panel to be adjusted between flat and curved modes, incorporating a vibration device to output sound forwardly, enhancing user immersion and sound quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a flat display panel is curved at a certain curvature to maximize user immersion, then viewing distance deviation decreases and visual immersion is maximized, but the curvature cannot vary based on user preference and sound quality degrades due to interference
Solution Approach 1:
The display panel transitions from a fixed curved state to a dynamic state where curvature can be adjusted between flat and curved configurations. The curvature adjustment mechanism allows the display panel to change its shape based on user preference, implementing adaptability while managing device complexity through a controlled transformation system.
Solution Approach 2:
The curvature parameter of the display panel is made variable rather than fixed. By changing the curvature parameter between different states (flat and curved), the system achieves adaptability to different user preferences and viewing conditions, resolving the contradiction between fixed curvature and user adaptability.
2Object-affected harmful factors
If sound is output in forward or downward direction from a curved display panel, then acoustic immersion is reduced due to sound interference from walls or ground reflections
Solution Approach 1:
The sound output direction is made dynamic and adjustable rather than fixed. The sound device can change its output direction to optimize acoustic performance, allowing users to select the best configuration for their environment and reducing harmful sound interference from reflections.
Solution Approach 2:
The sound output direction parameter is made variable, allowing adjustment between different directions (forward, downward, or other angles). This parameter change enables the system to avoid harmful sound interference by selecting optimal output directions based on environmental conditions.
