Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Hand-guided working apparatuses, particularly those with combustion engine or electric motor drive systems, are difficult to operate optimally due to the complexity of managing operational data values such as rotation speed, air flow, temperature, and power, leading to inefficient and potentially harmful usage.
Innovation Solution
A system comprising an optical recording device, identification device, and output device that records and identifies temporal successions of images and operational data values in real-time, allowing users to recognize and correct non-optimum operations, thereby ensuring ergonomic and optimal operation of the apparatus.

Engineering Contradiction Analysis
1Ease of operation
If users manually manage operational data values (rotation speed, air flow, temperature, power) of hand-guided working apparatuses, then they can control the drive system, but it becomes difficult to operate optimally due to the complexity of managing multiple parameters simultaneously
Solution Approach 1:
The system records operational data values (rotation speed, air flow, temperature, power) and provides visual feedback by displaying them alongside recorded images. This allows users to see the actual operational parameters during work procedures, enabling them to learn optimal parameter combinations through observation and imitation, thereby simplifying operation without reducing system capabilities
Solution Approach 2:
The system captures and stores optimal operational sequences by recording images together with their corresponding operational data values. Users can review these recorded sequences to copy proven optimal operating patterns, transforming complex parameter management into a learnable skill through observation of successful examples
2Productivity
If users operate hand-guided working apparatuses without real-time feedback on operational data, then the operation can proceed freely, but users cannot recognize or correct non-optimum operations in time
Solution Approach 1:
The system provides immediate visual feedback by displaying operational data values (rotation speed, air flow, temperature, power) together with recorded images during work procedures. This real-time feedback loop enables users to recognize non-optimum operations as they occur and make immediate corrections, improving working efficiency while maintaining operational freedom
3Reliability
If the system records and displays operational data values with recorded images, then users can analyze and improve their operation, but the system complexity and data processing requirements increase
Solution Approach 1:
The system merges the recording of images with the recording of operational data values into a single integrated process. By combining these data streams and displaying them together in a unified interface, the system provides comprehensive operational analysis capability without proportionally increasing overall system complexity
Solution Approach 2:
The recording and display system serves multiple functions: it captures images, records operational parameters, synchronizes them temporally, stores the combined data, and provides visual playback for analysis. This multi-functionality achieves reliable operational analysis while avoiding the need for separate specialized systems for each function
