Interactive Panel Antenna Through-Hole Layout for Narrow Frames
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing interactive white boards face challenges in achieving a narrow frame or full-screen design due to the presence of antennas on the frame, which occupy space and hinder the integration of a metal frame, affecting the screen-to-body ratio and structural strength.
Innovation Solution
The interactive white board design incorporates an antenna assembly on the metal backboard behind the display screen, utilizing through holes to radiate signals forward without occupying the frame region, allowing for a narrower frame and improved screen-to-body ratio, and enabling a full-screen design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If antennas are disposed on the frame, then wireless communication function is achieved, but the frame area increases and screen-to-body ratio decreases
Solution Approach 1:
The antenna is moved from the frame (peripheral dimension) to the display screen area (central dimension), specifically positioned in the lower right corner of the screen. This dimensional relocation allows the antenna to function within the display area rather than occupying frame space, thereby reducing frame area while maintaining wireless communication capability
Solution Approach 2:
The antenna is extracted from the frame structure and repositioned to the display screen area. By separating the antenna from the frame, the design eliminates the need for frame clearance regions, enabling narrower frames and higher screen-to-body ratios while preserving the wireless communication function
2Adaptability or versatility
If antennas are disposed on the frame, then wireless communication is enabled, but metal frame integration is hindered
Solution Approach 1:
The antenna is extracted from the frame structure and repositioned to the display screen area. This separation eliminates the conflict between antenna clearance requirements and metal frame integration, allowing the frame to be fully metal without structural complexity or compromise to wireless communication functionality
3Reliability
If antennas require clearance region, then antenna function is maintained, but full-screen design becomes impossible
Solution Approach 1:
Instead of requiring a general clearance region around the antenna, the design positions the antenna in a specific local area (lower right corner of the display screen) where it can function effectively. This localized positioning allows the rest of the screen to be fully utilized for display purposes, enabling full-screen design while maintaining antenna reliability
Solution Approach 2:
The antenna is relocated to the display screen area rather than the frame, utilizing the vertical and horizontal space within the screen boundaries. This repositioning eliminates the need for frame clearance regions and enables the frame to be minimized or eliminated, achieving full-screen design

Function Achieved in This Case
This configuration enhances the screen-to-body ratio, maintains structural strength through a metal frame, and prevents signal attenuation by positioning the antenna outside the shielding range of walls, improving the overall appearance and functionality.
Implementation Method 1
the antenna assembly is disposed directly opposite to the through holes, and can radiate signals forward through the through holes on the metal backboard and the display screen
