Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The compact design of electronic products limits the space for antenna structures, making it difficult to control the performance and frequency offset of antenna structures, which affects their functionality.
Innovation Solution
An electronic display device with a frame assembly, a first antenna, and a metal grounding member, where the metal grounding member is coupled to the grounding portion of the first antenna through a groove, allowing for improved adjustability and radiation efficiency by utilizing the spatial region on both sides of the housing body.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the grounding portion of the antenna structure is directly connected to the grounding layer of the circuit board in the same plane, then the grounding effect is achieved, but the space for disposing components is reduced and the adjustability of antenna performance is limited
Solution Approach 1:
The patent transitions from a two-dimensional planar connection to a three-dimensional spatial connection by extending the grounding portion vertically through the housing thickness. The grounding portion connects to the metal grounding member via a connection structure that spans across the housing, utilizing the third dimension (height/depth) to resolve the space conflict and enable performance adjustment.
Solution Approach 2:
The patent introduces a metal grounding member as an intermediary element between the antenna's grounding portion and the circuit board's grounding layer. This intermediary component is disposed on the outer surface of the housing and provides a configurable connection path, enabling both effective grounding and adjustable antenna performance through its position and configuration.
2Volume of moving object
If the electronic product is made smaller to reduce size, then the compactness is improved, but the accommodating space for antenna structures is reduced
Solution Approach 1:
The patent utilizes the vertical dimension (housing thickness) to accommodate the antenna structure and its grounding connection. By extending the grounding portion through the housing thickness and connecting to a metal grounding member on the outer surface, the design effectively uses the third dimension to provide sufficient antenna accommodation space without increasing the planar footprint of the product.
Solution Approach 2:
The antenna structure is integrated within the housing structure itself, with the grounding portion nested within the housing and the metal grounding member disposed on the outer surface. This nested arrangement allows the antenna system to be compactly integrated into the housing volume without requiring additional external space.
3Device complexity
If the antenna and circuit board are limited to the same plane, then the layout is simplified, but the control of antenna performance and frequency offset becomes difficult
Solution Approach 1:
The patent resolves the layout complexity by maintaining a relatively simple structure while adding vertical dimensionality. The grounding portion extends through the housing thickness and connects to the metal grounding member on the outer surface, creating a three-dimensional connection path that enables performance control without significantly complicating the overall layout.
Solution Approach 2:
The metal grounding member acts as an intermediary that provides configurable connection points and paths between the antenna grounding portion and the circuit board grounding layer. This intermediary structure enables adjustment of antenna performance and frequency offset by modifying the connection configuration, while maintaining a relatively simple overall layout.
