Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices face issues with sound quality deterioration and reduced user immersion due to sound output interference and inefficient vibration transmission to the user, particularly in vehicles.
Innovation Solution
A display device design incorporating a cover window, display panel, plates, a vibration bracket with upward legs, and a vibration film, which enhances vibration transmission in the depth direction through a leg structure and reinforces vibrations in both depth and planar directions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a vibration film is used to generate vibrations, then haptic characteristics can be provided, but the vibrations are not efficiently transmitted to the user in the depth direction
Solution Approach 1:
The patent introduces a vibration bracket with legs extending in the depth direction (z-axis) to transmit vibrations from the vibration film to the user. This adds a vertical dimension to vibration transmission, complementing the planar vibrations and enabling efficient haptic feedback in the depth direction.
Solution Approach 2:
The vibration bracket acts as an intermediary structure between the vibration film and the user's finger. The legs of the bracket transmit vibrations generated by the vibration film directly to the contact point, improving the efficiency and effectiveness of haptic transmission.
2Power
If sound is output from the back surface of the display device, then sound generation is achieved, but sound quality deteriorates and user immersion decreases due to interference with nearby structures
Solution Approach 1:
The patent directs sound waves to propagate in the depth direction (z-axis) using the vibration bracket structure, rather than allowing them to travel backward or downward from the display device. This dimensional change in sound propagation prevents interference with nearby structures and improves sound quality and user immersion.
3Device complexity
If a simple film structure is used for vibration generation, then device complexity is reduced, but vibration transmission in the depth direction is insufficient
Solution Approach 1:
The vibration bracket is segmented into multiple legs extending in the depth direction, with each leg contributing to vibration transmission. This segmentation allows the structure to effectively transmit vibrations while maintaining relative simplicity in manufacturing.
Solution Approach 2:
The vibration bracket combines structural elements (legs and bridges) that work together to transmit vibrations in both depth and planar directions. This composite structure achieves precise vibration transmission without significantly increasing device complexity.
