Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a laser range finder is used to measure pool parameters, then measurement precision is improved, but device complexity and ease of operation deteriorate
Solution Approach 1:
The patent replaces the mechanical laser range finder with a terminal device (smartphone or tablet) that uses camera imaging and image processing algorithms to measure pool parameters. The terminal device captures images of the pool environment and automatically calculates dimensions through computational methods, eliminating the need for manual laser measurement and significantly improving ease of operation while maintaining measurement precision.
2Measurement precision
If manual measurement with laser range finder is used, then measurement precision is improved, but loss of time increases
Solution Approach 1:
The patent performs preliminary action by having the terminal device automatically capture pool environment images and pre-process the visual data before the cleaning robot operates. The system pre-calculates pool parameters and generates cleaning path plans in advance, eliminating the time-consuming manual measurement step and reducing overall preparation time while maintaining accurate measurements through image-based computation.
3Measurement precision
If laser range finder is used for measurement, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The patent applies universality by using a terminal device (smartphone or tablet) that serves multiple functions: it captures pool environment images, processes visual data to measure pool parameters, generates cleaning path plans, and communicates with the cleaning robot. This multi-functional approach replaces the specialized laser range finder, reducing overall system complexity while maintaining measurement precision through integrated software-based measurement capabilities.
