Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices face challenges in efficiently mounting electrical connection structures, such as coaxial cables and flexible printed circuit boards, due to limited mounting space, leading to reduced battery size or increased device size.
Innovation Solution
A stacked structure of a coaxial cable and/or an antenna module is implemented within the electronic device, where the coaxial cable is stacked with the antenna module and fixed using a bracket, allowing for efficient use of mounting space and maximizing battery capacity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If electrical connection structures (coaxial cable and flexible printed circuit board) are mounted inside the electronic device, then antenna modules can be electrically connected to processors, but the size and capacity of the battery are reduced or the size of the electronic device is increased
Solution Approach 1:
The patent transitions from planar mounting to three-dimensional stacked mounting. The coaxial cable is positioned vertically above the antenna module in the Z-direction, creating a stacked configuration that utilizes the third dimension for spatial arrangement. This dimensional change allows electrical connection structures to occupy vertical space rather than horizontal space, thereby preserving battery capacity in the limited internal volume of the electronic device.
Solution Approach 2:
The patent implements a nested arrangement where the coaxial cable is positioned within the vertical projection area of the antenna module. The coaxial cable structure is effectively nested within the spatial envelope defined by the antenna module, allowing compact integration of multiple components in a hierarchical spatial relationship that maximizes space utilization.

3Reliability
If a separate member is used to fix the coaxial cable, then the coaxial cable can be securely mounted, but manufacturing costs increase and assembly complexity increases
Solution Approach 1:
The patent merges the coaxial cable fixation function with the existing antenna module bracket. The bracket, which already serves to position and secure the antenna module, is modified to include coaxial cable fixation features such as clamps or retention structures. This consolidation eliminates the need for separate fixation members, reducing component count, simplifying assembly, and lowering manufacturing costs while maintaining reliable coaxial cable positioning.
