Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multi-antenna communication systems are integrated into tablet PC type electronic devices, then communication capability is improved, but peripheral mechanism space is insufficient
Solution Approach 1:
The antenna bracket is nested within the existing side button mechanism structure. The bracket utilizes the hollow space formed by the side button's recessed design, effectively nesting the antenna component within the existing peripheral mechanism without requiring additional external space.
Solution Approach 2:
The invention transitions from traditional planar antenna layouts to a three-dimensional spatial configuration. The antenna bracket extends in multiple directions (upward, downward, leftward, rightward) from the side button area, utilizing vertical and horizontal dimensions simultaneously to create adequate antenna surface area within limited peripheral space.
2Ease of manufacture
If traditional antenna designs are used, then manufacturing is simpler, but space utilization is insufficient
Solution Approach 1:
The antenna bracket is merged with the side button mechanism as an integrated assembly. The bracket serves dual purposes: it provides structural support for the side button while simultaneously functioning as the antenna radiation element, eliminating the need for separate antenna components and simplifying the manufacturing process.
Solution Approach 2:
The side button mechanism is designed with multi-functionality, serving both as a user interaction component and as an antenna support structure. The hollow portion of the side button mechanism is utilized to accommodate the antenna bracket, allowing the same structural element to fulfill multiple functional roles within the device.

AI summary
An electronic device includes a housing, a metal support plate, a three-dimensional antenna bracket and a side button circuit board. The housing includes an upper housing body and a lower housing body. The metal support plate is arranged in the housing. The three-dimensional antenna bracket is arranged in a first space between the metal support plate and the lower housing body. The side button circuit board is arranged in a second space between the metal support plate and the upper housing body. The area of the three-dimensional antenna bracket and the area of the side button circuit board on the metal support plate overlap with each other. Thus, the electronic device can meet the design requirement for a plurality of antennae, and the three-dimensional antenna bracket and the metal support plate form a radiation cavity to resonate to generate a target antenna frequency band and an available radiation pattern.
