Solution Overview
Problem
Existing systems for connecting power tools with rechargeable batteries face complexity, susceptibility to interference, and security vulnerabilities during data and information exchange, particularly with wireless transmission methods like Bluetooth.
Innovation Solution
A system utilizing both wired and wireless transceivers for data exchange between power tools and rechargeable batteries, where wired transceivers facilitate initial connection setup and wireless transceivers handle larger data volumes, enhancing security and reducing unauthorized access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wireless transmission device (e.g., Bluetooth) is used for data exchange between power tool and rechargeable battery, then ease of operation and adaptability are improved, but security and reliability deteriorate due to susceptibility to unauthorized entry and eavesdropping
Solution Approach 1:
The data transmission function is segmented into two separate transmission devices: a wired transmission device for secure initial connection setup and authentication, and a wireless transmission device for subsequent data exchange. This segmentation allows each transmission mode to be optimized for its specific purpose, with the wired connection providing security for critical authentication processes.
2Reliability
If complex authentication procedures are implemented to secure wireless data transmission, then security is improved, but device complexity and susceptibility to interference increase
Solution Approach 1:
The wired transmission device acts as an intermediary for the initial connection setup and authentication process. By using this intermediate wired connection to establish secure authentication before switching to wireless transmission, the system avoids the need for complex wireless authentication procedures while maintaining high security standards.
3Reliability
If wired transmission device is used for initial connection setup, then security against unauthorized entry and eavesdropping is improved, but ease of operation and adaptability may deteriorate
Solution Approach 1:
The wired transmission device is used to perform preliminary actions of connection setup and authentication before the main data exchange operation begins. This preliminary secure connection establishes trust and security parameters, allowing the subsequent wireless data exchange to proceed smoothly without requiring repeated authentication, thus maintaining ease of operation.
