Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Operators of handheld tools, especially those less experienced, face challenges in maintaining the orientation of tools during operations on uneven or sloped surfaces, as manual control is difficult and prone to errors, necessitating a means to accurately monitor and correct tool orientation.
Innovation Solution
A motion monitoring device for handheld tools, incorporating a motion sensor to detect orientation and a processor to determine tilting ranges, coupled with visual, tactile, or audible indicators to provide feedback on orientation status, and a communication module for external device interaction, allowing for calibration and adjustment of tilting thresholds.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If operators rely on naked eye judgment to control tool orientation, then the device complexity remains low, but the orientation control precision deteriorates
Solution Approach 1:
The patent replaces the mechanical/visual judgment system with electronic sensors (acceleration sensors, gyroscopes) and processing units that electronically detect and measure tool orientation, thereby improving measurement precision without significantly increasing overall system complexity
Solution Approach 2:
The patent introduces intermediate components including sensors, processing units, and display devices that mediate between the tool and the operator, providing processed orientation information that enhances control precision while keeping the added complexity manageable through modular design
2Reliability
If operators manually control tool orientation on uneven or sloped ground, then the ease of operation is maintained, but the reliability of maintaining consistent orientation deteriorates
Solution Approach 1:
The patent implements feedback mechanisms where sensors continuously monitor tool orientation and provide real-time information through display devices, enabling operators to make corrective adjustments and maintain consistent orientation reliably across varying terrain conditions
Solution Approach 2:
The system provides self-service orientation monitoring and guidance, automatically detecting tool orientation and presenting correction information to the operator without requiring external assistance or complex manual measurement procedures
3Productivity
If no orientation feedback is provided to operators, then the device complexity remains low, but the productivity deteriorates due to repeated errors and corrections
Solution Approach 1:
The patent implements feedback mechanisms where sensors continuously monitor tool orientation and provide real-time information through display devices, enabling operators to make corrective adjustments and maintain consistent orientation reliably across varying terrain conditions
Solution Approach 2:
The patent replaces the mechanical/visual judgment system with electronic sensors (acceleration sensors, gyroscopes) and processing units that electronically detect and measure tool orientation, thereby improving measurement precision without significantly increasing overall system complexity
