Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Large-sized display devices experience noise due to vibration of the rear housing when playing sound, degrading user experience.
Innovation Solution
Incorporating a buffer between the non-display surface of the display module and the rear housing, which can include block or strip buffers made of magnetic or elastic insulation materials, to absorb and mitigate the vibration caused by sound vibrations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If a large-sized display device is used, then the display area is increased, but the rear housing vibration noise is enhanced
Solution Approach 1:
A buffer is introduced as an intermediary component between the display module and the rear housing. This buffer absorbs and attenuates the vibrations generated by the display module, preventing them from being transmitted to the rear housing. The buffer acts as a mediator that decouples the vibration source from the housing structure, thereby reducing the noise generated by rear housing vibration while preserving the large display area.
2Area of stationary object
If the rear housing size is increased, then the display device size is increased, but the vibration noise is increased
Solution Approach 1:
The buffer serves as a vibration-isolating intermediary positioned between the display module and the rear housing. It selectively transmits static loads while attenuating dynamic vibrations, allowing the rear housing to maintain its large size for structural support and aesthetics without becoming a noise-generating resonant structure.
3Object-generated harmful factors
If the buffer is added between display module and rear housing, then the vibration noise is reduced, but the device complexity is increased
Solution Approach 1:
The buffer is implemented as a flexible vibration-absorbing layer that can be directly applied to the rear housing surface. This thin-film approach provides effective vibration isolation without adding significant structural complexity or thickness to the overall device assembly.
Solution Approach 2:
The buffer utilizes composite material structures that combine different material properties to achieve optimal vibration absorption. By selecting materials with appropriate damping characteristics, the buffer effectively reduces vibration noise while maintaining a simple single-component implementation that does not significantly increase device complexity.
