Solution Overview

Problem

The size of wireless BMS modules increases due to the installation of antennas, necessitating a need for a module that reduces size while maintaining functionality.

Innovation Solution

An antenna-in-package (AiP) module with a cover-type antenna, where one chipset is embedded and another is disposed on a substrate, utilizing a radiating unit shaped as a cover to minimize spatial requirements, and incorporating shielding layers and walls to reduce interference and interference.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If an antenna is mounted on a wireless BMS to enable wireless communication, then wireless communication functionality is achieved, but the size of the BMS module increases

Engineering Contradiction:
Improvewireless communication functionalityVSAvoidBMS module size
Core Design Contradiction:
Adaptability or versatilityVSArea of stationary object

Solution Approach 1:

The patent combines the antenna with the substrate by forming the antenna directly on the substrate surface, merging two previously separate components (antenna and substrate) into a single integrated structure. This eliminates the need for additional antenna mounting space and reduces the overall module size while maintaining wireless communication functionality

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The substrate serves multiple functions: it provides mechanical support for the electronic components, acts as the mounting platform for the antenna, and functions as the radiating element for wireless communication. This multi-functionality eliminates the need for separate antenna structures and reduces the overall module footprint

Inventive Principle:
Principle #6Universality (Multi-functionality)
