Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Integrating wireless-enabling circuits, such as those for PAN and RFID, into electronic devices like cell phones is costly and reduces the functionality of SD-card slots, making it difficult to support applications like Micro-SD cards or Mini-PCI without increasing device costs.
Innovation Solution
The integration of a processor and antenna directly into a battery pack allows for wireless communication with electronic devices, eliminating the need for additional metallic connections and preserving SD-card slots by using a radio link for communication, thereby reducing hardware costs and improving RF communication range and reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If wireless-enabling circuits (PAN, RFID) are integrated into electronic devices, then wireless communication capability is improved, but device cost increases and SD-card slot functionality is reduced
Solution Approach 1:
The patent extracts the wireless communication circuits (processor and antenna for PAN and RFID) from the main electronic device and relocates them to the battery pack. This allows the electronic device to gain wireless capability without integrating complex circuits into its main body, thereby avoiding increased device cost and preserving SD-card slot functionality.
Solution Approach 2:
The battery pack serves as an intermediary carrier that houses the wireless communication circuits. The processor in the battery pack communicates with the electronic device through established interfaces, enabling wireless functionality without direct integration into the electronic device's main circuitry.
2Reliability
If additional metallic connections are added for wireless communication, then communication reliability is improved, but hardware cost and device complexity increase
Solution Approach 1:
The battery pack is designed to serve multiple functions: it provides power to the electronic device and simultaneously houses the wireless communication circuits. This multi-functional design eliminates the need for additional separate components and metallic connections, reducing hardware cost while maintaining communication reliability through the existing battery pack interface.
