Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Self-propelled cleaning devices face challenges in targeted demonstration and testing due to unpredictable behavior in cleaning mode, requiring extensive laboratory setups and configurations, which can be time-consuming and impractical for customer demonstrations or troubleshooting.
Innovation Solution
A method and device that allow for a predictable and reproducible demonstration mode, where the cleaning device follows a preset path, reacts to obstacles, and returns to a starting position, enabling easy testing and demonstration of functions without prior configuration or data connection, with adjustable settings for different environments and functions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the cleaning device operates in cleaning mode with autonomous navigation, then the cleaning coverage and adaptability to real environments are improved, but the behavior becomes unpredictable and difficult to demonstrate or test
Solution Approach 1:
The system dynamically switches between two operational modes: cleaning mode with autonomous navigation for real environment adaptation, and demonstration mode with predetermined paths for predictable behavior. This dynamic mode switching allows the device to exhibit different behavioral characteristics depending on the operational context, resolving the contradiction between adaptability and predictability
2Measurement precision
If laboratory testing is performed with specialized measuring devices, then the functionality of sensors and motors can be examined in detail, but the test environment differs from actual use conditions and requires extensive setup
Solution Approach 1:
The cleaning device performs self-testing and self-demonstration capabilities through automated return-to-start functions and predetermined path execution. This eliminates the need for external laboratory equipment and specialized measuring devices, allowing the device to test and demonstrate its own functions in realistic environments without complex setup
3Productivity
If the cleaning device returns to starting position automatically after demonstration, then the reproducibility and efficiency of sequential testing are improved, but additional control logic and positioning functions are required
Solution Approach 1:
The system establishes a predetermined demonstration path and starting position before the demonstration begins. During demonstration, the device automatically returns to the pre-established starting position and reorients to the starting orientation, enabling immediate repetition of the same demonstration sequence. This preliminary setup of reference points allows automated reproducibility without complex real-time control logic
