Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional mobile home robot uses a fixed wheel structure for movement, then it can maintain structural simplicity, but it cannot efficiently navigate narrow spaces or change directions freely
Solution Approach 1:
The mobile robot is divided into two independent movement systems: a ball structure for whole-body displacement and an outer ring structure for directional adjustment. This segmentation allows each component to specialize in specific movement tasks, enabling free direction changes in narrow spaces without requiring a completely complex redesign of the entire movement system
Solution Approach 2:
The patent implements dynamic movement capabilities by making the outer ring structure rotatable relative to the ball structure. This dynamic configuration allows the robot to adjust its orientation independently while moving, providing adaptability for navigating narrow spaces and changing directions freely without being constrained by a fixed wheel structure
2Adaptability or versatility
If the mobile robot uses a complex multi-component movement system for free direction changes, then it can achieve high maneuverability, but it becomes difficult to maintain aesthetic appearance and structural stability
Solution Approach 1:
The outer ring structure is nested within or coupled to the ball structure, with the inner ring structure arranged inside the housing to face the outer ring structure. This nested configuration allows multiple movement functions to be integrated within a compact form, maintaining structural stability and aesthetic appearance while enabling free direction changes through coordinated movement of the nested components
Solution Approach 2:
The patent combines the ball structure and outer ring structure into a unified movement system where both components work together under coordinated control. This merging of functions maintains structural integrity and aesthetic appearance while achieving high maneuverability through the integrated operation of the combined structures
3Speed
If the mobile robot uses traditional mechanical contact-based movement, then it can maintain simple control mechanisms, but it cannot achieve rapid and stable operations
Solution Approach 1:
The patent replaces traditional mechanical contact-based movement with magnetic levitation technology. Magnets are arranged on the ball structure and outer ring structure to enable contactless propulsion and stabilization. This substitution eliminates mechanical friction and wear, achieving rapid and stable operations while the coordinated control of magnetic fields provides precise movement without complex mechanical linkages
