Universal Power Tool Identification via Vibration Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Many older power tools lack sensors to measure usage characteristics, and users face challenges in finding relevant resources due to the overwhelming amount of irrelevant information available online.
Innovation Solution
A system comprising a usage attachment with sensors that measure and transmit usage data, allowing identification of the power tool type through comparison with predetermined data, and providing users with relevant resources based on their tool usage profiles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a separate attachment with sensors is provided for each power tool type, then measurement precision of usage characteristics is improved, but device complexity and cost increase
Solution Approach 1:
The usage attachment is designed with universal compatibility to attach to multiple different power tool types through a standardized interface. The attachment includes sensors that can detect usage characteristics across various tool types, and the system automatically identifies the tool type to apply appropriate measurement parameters, eliminating the need for separate attachments for each tool type while maintaining measurement precision
Solution Approach 2:
The system dynamically changes measurement parameters based on the identified power tool type. When a usage attachment detects a different tool type, it adjusts sensor thresholds, sampling rates, and analysis parameters automatically, allowing a single attachment to accurately measure usage characteristics across multiple tool types without requiring tool-specific calibration
2Loss of information
If comprehensive resources are provided for all power tool users, then information completeness is improved, but ease of operation deteriorates due to information overload
Solution Approach 1:
The system uses feedback from the usage attachment's measurements of actual power tool usage characteristics to automatically determine which resources are most relevant to each user. By analyzing how users actually use their tools (runtime, cycles, load conditions), the system feedback-adjusts resource recommendations to match observed usage patterns, providing comprehensive information filtered by actual user needs rather than generic categorizations
Solution Approach 2:
The system performs preliminary analysis of usage characteristics before presenting resources to users. The usage attachment continuously monitors and stores usage data, and the system pre-processes this information to identify user profiles and resource needs in advance, so when users access resources, they receive pre-filtered, relevant information rather than having to search through comprehensive but overwhelming content
Data Source
AI summary
A system for identifying a type of a power tool, the system comprising: a power tool having an electric motor; and a usage attachment configured to couple to the power tool, the usage attachment having a vibration sensor that generates vibration data when the power tool vibrates, a memory that stores the vibration data generated by the vibration sensor, and an identification subsystem that receives the vibration data from the memory, and identifies the type of the power tool by comparing the received vibration data to predetermined vibration data of a known type of power tool.
