Solution Overview
Problem
Existing power tools and portable power supply devices face challenges in software updates, which require disassembly and debugging, leading to resource-intensive and time-consuming processes, and are prone to incomplete updates causing safety hazards due to interrupted program transmission.
Innovation Solution
An electrical device with a control module, communication module, and storage module facilitates wireless program updates, ensuring safe, reliable, and efficient upgrades without disassembly, using a communication module to receive and store upgrade files and send them to the control module under preset conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If traditional disassembly and debugging method is used for software updates, then program update can be implemented, but it requires a lot of manpower and resources and delays the project cycle
Solution Approach 1:
The patent replaces the mechanical disassembly and debugging process with a wireless communication system. The communication module receives upgrade files wirelessly from external devices, stores them in the storage module, and transmits them to the control module for program updates, eliminating the need for physical disassembly and manual debugging operations.
Solution Approach 2:
The system enables self-updating capability where the electrical device automatically receives, stores, and processes upgrade files through its integrated communication and storage modules. The control module can autonomously execute the updated program without requiring external manual intervention or disassembly operations.
2Ease of operation
If program update is performed through disassembly and debugging, then software changes can be implemented, but it requires manual intervention and resources
Solution Approach 1:
The electrical device integrates multiple functions into unified modules: the communication module handles both data transmission and reception, the storage module manages both upgrade file storage and program storage, and the control module executes both normal operations and update processes. This multi-functionality simplifies the update operation while reducing overall system complexity.
3Reliability
If upgrade file transmission is interrupted during program update, then update process stops, but incomplete upgrade file or updated program causes device to work improperly and brings safety hazard
Solution Approach 1:
The storage module stores the complete upgrade file before the control module begins the program update process. This preliminary storage ensures that the entire update program is available and intact before execution starts, preventing safety hazards from incomplete transmissions during the update process.
Solution Approach 2:
The storage module acts as an intermediary between the communication module and the control module. It receives and stores upgrade files from external devices, then provides complete programs to the control module for execution. This intermediary role ensures data integrity by separating the transmission phase from the execution phase, allowing verification of complete file reception before updating.
