Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the antenna is installed within the electronic device to provide wireless transmission function, then the wireless communication function is achieved, but the electronic components may interfere the antenna and adversely affect the performance of the antenna
Solution Approach 1:
The patent divides the antenna structure into multiple segments: a first antenna portion disposed within the operation body and a second antenna portion extending outward from the frame. This segmentation allows the antenna to maintain its wireless communication function while reducing interference from internal electronic components, as the portions outside the operation body are less susceptible to such interference.
Solution Approach 2:
The patent extends the antenna structure from a two-dimensional planar arrangement to a three-dimensional configuration by having the antenna extend outward from the frame. This dimensional change allows the antenna to transcend the boundary of the operation body, positioning part of it in a space less affected by internal electronic component interference.
2Strength
If the frame encloses the lateral side of the operation body to provide protection, then the protectiveness is improved, but the internal space for component arrangement is reduced
Solution Approach 1:
The patent segments the antenna structure into portions that exist both within and outside the frame enclosure. This allows the frame to maintain its protective enclosure function while the antenna extends beyond the frame's boundaries, effectively utilizing the space around the operation body without compromising internal component arrangement space.
Solution Approach 2:
The frame acts as an intermediary structure that provides protection to the operation body while simultaneously serving as a mounting structure for the antenna. The frame's lateral enclosure provides mechanical protection, while its structure facilitates the antenna's extended configuration, resolving the conflict between protection and space utilization.
3Object-affected harmful factors
If the antenna is partially exposed outside the frame, then the interference from internal components is reduced, but the device complexity increases
Solution Approach 1:
The frame structure serves multiple functions: it provides lateral protection to the operation body, acts as a mounting structure for the antenna, and facilitates the antenna's extended configuration. This multi-functionality reduces the need for additional specialized components, thereby limiting the increase in device complexity despite the antenna's extended design.
Solution Approach 2:
The patent merges the protective frame structure with the antenna mounting structure into a single integrated design. The frame both protects the operation body and provides the structural framework for the antenna extension, combining multiple functions into one element and thereby limiting the increase in overall device complexity.

AI summary
An electronic device includes an operation body, a frame and an antenna. The frame encloses a lateral side of the operation body. The antenna is disposed within the frame, and partially exposed outside the frame. The antenna is electrically connected with the operation body to provide a wireless communication function. A wireless communication interference source is disposed within the operation body, or the operation body contains a metallic material. Since the operation body is enclosed by the frame, the frame can protect operation body and prevent collision of the operation body. Moreover, since the antenna is located outside the operation body, the antenna is away from the interference source that is disposed within the operation body. Consequently, the wireless communication efficiency is enhanced, and the inner space of the operation body is saved.
