Solution Overview
Problem
Conventional display devices face limitations in reducing thickness due to the integration of display panels, speakers, and electronic components, and require wired connections for data transmission, which restricts their slimness and wireless communication capabilities.
Innovation Solution
A display device design featuring a main body with a display and an outer box containing a control board, where wireless communication is enabled through a first and second antenna, an antenna bracket, and an antenna cover made of transparent or translucent plastic with a low dielectric constant, allowing for improved communication sensitivity and reduced manufacturing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If the control board and electronic components are integrated into the main body, then the device structure is simplified, but the thickness cannot be reduced and the outer appearance is compromised
Solution Approach 1:
The display device is divided into two separate parts: the main body containing the display panel and the outer box containing the control board and electronic components. This segmentation allows the main body to be slim while housing the display, and the outer box to contain the bulkier electronic components, thereby resolving the contradiction between thickness reduction and structural complexity.
2Adaptability or versatility
If wired connection is used to connect display and electric part, then data transmission is reliable, but the device cannot achieve wireless communication capability
Solution Approach 1:
The mechanical wired connection system is replaced with a wireless communication system using antennas. The first antenna is provided in the main body and the second antenna in the outer box, enabling wireless data transmission between the display and control board, thus achieving wireless communication capability while maintaining data transmission functionality.
3Reliability
If conventional antenna housing material is used, then manufacturing is simple, but communication sensitivity is poor due to high dielectric constant
Solution Approach 1:
The dielectric constant parameter of the antenna cover material is changed from conventional high values to specifically less than 3. This parameter change significantly improves communication sensitivity by reducing radio wave loss, while still allowing the use of plastic materials that can be manufactured using conventional processes, thus balancing performance and manufacturability.
4Reliability
If expensive low dielectric constant material is used throughout the antenna assembly, then communication sensitivity is improved, but manufacturing cost increases
Solution Approach 1:
Instead of using expensive low dielectric constant material throughout the entire antenna assembly, the invention applies this special material only to the antenna cover portion that directly contacts the antenna elements. The coupling portion and other non-critical components can use conventional, cheaper materials, thus achieving improved communication sensitivity while controlling manufacturing costs.
