Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If sign objects are used to limit cleaning area, then cleaning robot safety is improved, but device complexity and cost increase
Solution Approach 1:
The patent extracts the boundary definition function from physical sign objects and transfers it to a virtual map system. The cleaning robot uses a map generated by map generation means (such as laser ranging or vision sensors) to define cleaning boundaries, eliminating the need for physical sign objects in the environment.
Solution Approach 2:
The patent creates a virtual copy of the physical environment through map generation. Instead of using physical sign objects to mark boundaries, the system generates a digital map representation of the space, which the cleaning robot then uses for navigation and boundary recognition.
2Manufacturing precision
If multiple sign objects are placed to reduce cleaning area, then cleaning precision is improved, but cost and aesthetic impact increase
Solution Approach 1:
The patent removes the need for multiple physical sign objects by extracting the boundary definition function and implementing it through a virtual map system. The map generation means creates a precise digital representation of the cleaning area boundaries, eliminating the need for numerous physical markers.
Solution Approach 2:
The patent changes the parameter of boundary representation from physical objects to digital information. By transforming the boundary definition from tangible sign objects to virtual map data, the system achieves precise area control without the quantity and aesthetic issues of physical objects.
3Measurement precision
If manual placement of sign objects is required, then operation simplicity is reduced, but measurement precision is improved
Solution Approach 1:
The patent implements self-service by enabling the cleaning robot to automatically generate its own cleaning map using integrated map generation means. The robot autonomously navigates the space, detects boundaries, and creates a digital map without requiring manual placement of sign objects by users.
Solution Approach 2:
The patent replaces the mechanical system of manually placing physical sign objects with an automated sensing and mapping system. The map generation means (laser ranging, vision sensors) automatically detect and record boundary information, substituting manual mechanical operations with automated electronic measurement.
