Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing thickness of TVs and the resulting reduction in radiation space between the TV and the wall lead to radiation degradation, as the distance between the wireless module and the metal plate, as well as the concrete wall, becomes insufficient for effective signal radiation.
Innovation Solution
An antenna module comprising a first and second radiation part, each applied with a current via feeder lines, and corresponding coupling radiation parts spaced apart and coupled to the radiation parts, allowing for signal radiation in different frequency bands and overcoming radiation space constraints.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If TV thickness is reduced to increase thinness, then the aesthetic appearance and space-saving design are improved, but the radiation space between the TV and wall is reduced causing radiation degradation
Solution Approach 1:
The patent introduces a coupling radiation part that extends in a direction substantially perpendicular to the radiation part, creating a three-dimensional radiation structure. This dimensional extension allows the antenna to radiate effectively even when the TV is placed close to a wall, as the coupling radiation part projects into the limited space between the TV and wall, compensating for the reduced thickness-induced space constraint.
Solution Approach 2:
The coupling radiation part acts as an intermediary between the radiation part and the wall, facilitating signal radiation in the constrained space. By positioning the coupling radiation part between the radiation part and the wall (with specific spacing relationships), it mediates the interaction between the antenna system and the wall, enabling effective radiation despite the proximity constraint imposed by thin TV design.
2Device complexity
If the distance between the wireless module and the metal plate is reduced to achieve a compact design, then the device integration is improved, but the radiation current formation is degraded
Solution Approach 1:
The coupling radiation part extends perpendicular to the radiation part, creating a spatial configuration that maintains effective radiation current paths even when the overall antenna structure is compactly integrated with the TV. This dimensional extension allows the radiation current to flow through multiple paths (radiation part and coupling radiation part), ensuring reliable current formation despite reduced spacing between components.
