Mobile Power Tool Wear Detection for Productive Reuse Decisions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Construction tools, especially those used on sites like drilling or chiseling, suffer from heavy wear, leading to reduced productivity due to minor damage, which can result in longer drilling times or tool failure, causing time and financial losses.
Innovation Solution
A method and mobile power tool system that monitors tool properties, such as wear, to determine when to reuse, replace, or service the tool, using image recording units, sensors, and trainable filters to assess tool condition and adjust operation parameters for optimal productivity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If tools are used continuously without monitoring, then productivity is maintained in the short term, but tool wear leads to failure and longer downtime later
Solution Approach 1:
The system performs preliminary monitoring of tool properties (wear, damage, contamination) before critical failure occurs. By continuously assessing tool condition and predicting remaining service life, maintenance can be scheduled proactively, preventing unexpected tool failure and ensuring continuous productivity without sacrificing reliability.
2Reliability
If tool monitoring and measurement systems are implemented, then tool reliability and productivity are improved, but device complexity increases
Solution Approach 1:
The tool itself is equipped with integrated sensors and measurement units that automatically monitor its own properties (wear, damage, contamination). This self-monitoring capability eliminates the need for complex external inspection systems, as the tool provides its own diagnostic data, thereby improving reliability without proportionally increasing overall system complexity.
Solution Approach 2:
The system establishes a feedback loop where tool condition data is continuously collected by sensors, processed by evaluation units, and used to adjust operation parameters or trigger maintenance alerts. This automated feedback mechanism simplifies the monitoring system compared to manual inspection methods while significantly improving tool reliability through real-time condition assessment.
3Measurement precision
If detailed property measurement and classification are performed, then measurement precision is improved, but loss of time for inspection increases
Solution Approach 1:
The measurement and monitoring process operates continuously during tool operation rather than requiring separate inspection stops. Sensors continuously capture tool condition data, and the evaluation unit processes this information in real-time, maintaining both high measurement precision and continuous productivity without time loss for manual inspections.
Solution Approach 2:
Manual inspection methods are replaced with automated optical sensors, image recording units, and computer vision algorithms. These electronic measurement systems provide precise tool condition assessment instantly, eliminating the time-consuming nature of manual measurement while maintaining or improving measurement precision through digital image analysis and automated feature detection.
