Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a robotic passenger uses a pre-set fixed elevator-waiting position, then the robot can efficiently wait for the elevator, but the position may be occupied by human passengers causing the robot to become sluggish and spin around
Solution Approach 1:
The patent applies dynamics by transitioning from a fixed, static waiting position to a dynamic position selection system. The robot dynamically determines its waiting position based on real-time detection of occupancy status, choosing between first-choice and candidate positions. This dynamic adaptation eliminates the harmful effect of fixed positions being occupied while maintaining efficient waiting behavior.
Solution Approach 2:
The patent implements feedback through a detection device that continuously monitors whether the first-choice elevator-waiting position is occupied. This feedback information is used by the position allocation unit to adjust the robot's waiting position selection. The closed-loop feedback mechanism ensures the robot can respond to occupancy changes and avoid obstructing human passengers while maintaining efficient elevator waiting.
2Object-generated harmful factors
If the robotic passenger detects and switches to a candidate elevator-waiting position when the first-choice position is occupied, then obstruction to human passengers is reduced, but the system complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the elevator-waiting area into multiple distinct positions: a first-choice position and multiple candidate positions. This segmentation allows the system to distribute robots across different locations based on occupancy, reducing conflicts and obstruction to human passengers. The segmented position structure simplifies the decision logic compared to a fully dynamic path-planning approach.
Solution Approach 2:
The patent implements local quality by assigning different functions to different waiting positions. The first-choice position is optimized for efficient elevator access, while candidate positions serve as alternative locations when the first-choice position is occupied. Each position has specific characteristics and purposes, allowing the system to reduce obstruction to humans while maintaining overall efficiency without requiring complex global optimization.
