Irregular Battery Surrounding Main Board in Intelligent Terminal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The traditional broken board structure in intelligent terminals results in poor signal transmission reliability, low board space utilization, heat dissipation issues, and compromised electromagnetic compatibility due to the irregular shape and separate sub-boards.
Innovation Solution
The intelligent terminal design features a main board with a regular or irregular polygon shape, where the battery at least half surrounds the main board, eliminating the need for Flexible Printed Circuits (FPC) to connect sub-boards, and optimizing the arrangement of power, signal processing, and memory components for improved space utilization and reduced heat generation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If a broken board structure is used to arrange the main board, then the battery can be placed in a regular shape, but the signal transmission reliability deteriorates and board space utilization decreases
Solution Approach 1:
The patent divides the terminal interior space into distinct functional zones: the battery occupies a regular-shaped central region while the main board is segmented into multiple sub-boards arranged around it. This segmentation allows the battery to maintain a simple regular shape for better manufacturing and heat dissipation, while the segmented main board adapts to the remaining space, eliminating the need for complex FPC connections and improving signal reliability.
2Device complexity
If the main board is arranged first in traditional design, then the layout is simplified, but the board space utilization deteriorates
Solution Approach 1:
The patent inverts the traditional design sequence by placing the battery first in a regular central position, then arranging the main board and its sub-boards around the remaining space. This inversion allows optimal utilization of available board space while maintaining manageable layout complexity through systematic component placement.
3Device complexity
If the battery occupies the core location, then the terminal structure is simplified, but heat dissipation deteriorates
Solution Approach 1:
The patent creates an asymmetric thermal management structure where the battery, despite being centrally located, is surrounded by strategically positioned heat dissipation components including the main board with its electronic components, shell with heat dissipation areas, and specifically arranged heat dissipation components. This asymmetric arrangement optimizes heat flow paths while maintaining structural simplicity.
