Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the robot uses sensors to detect obstacles and frequently collides with them to alter its path, then the robot can change its moving path, but it generates a lot of noises and shortens the service life of the robot
Solution Approach 1:
The robot performs preliminary detection using signal transmitters and receivers to identify obstacles and determine keep-away distances before actual contact occurs. The control module calculates appropriate distances based on signal characteristics, allowing the robot to adjust its path proactively without needing to collide with obstacles to change direction.
2Difficulty of detecting and measuring
If the robot uses transmitters and receivers to send and receive bounced-back signals from obstacles, then the robot can detect obstacles, but it cannot distinguish obstacles with different properties leading to misjudgments and violent collisions
Solution Approach 1:
The control module analyzes the characteristics of bounced-back signals (such as signal strength, frequency, or phase changes) to infer properties of obstacles like material composition, surface smoothness, or color. This feedback mechanism allows the robot to distinguish between different obstacle types and adjust its behavior accordingly, avoiding violent collisions with certain obstacle types while maintaining detection capability for all obstacles.
3Adaptability or versatility
If the robot frequently touches obstacles to determine path changes, then the robot can adjust its moving path, but it causes inconvenience in practical use and damages the robot
Solution Approach 1:
The patent replaces the mechanical collision-based path adjustment method with a signal-based detection and calculation system. The control module uses signal characteristics from transmitters and receivers to computationally determine keep-away distances and plan paths, eliminating the need for physical contact with obstacles for navigation decisions, thereby improving practical usability while maintaining path adaptability.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution reduces noise and damage to the robot, enhances efficiency, and extends its service life by minimizing collisions and misjudgments when encountering obstacles with different properties.
Implementation Method 1
the signal transmitters send out signals to the obstacle and then the signal receivers may receive the bounced-back signals from the obstacle

AI summary
An auto re-directing robot able to adjust its moving paths automatically and a method thereof are disclosed in present invention. The auto re-directing robot has a control module, which may generate a signal standard value according to the bounced-back signals from an obstacle. Then, the control module determines a keep-away distance between the robot and the obstacle. In the case, the robot needs not to touch the obstacle repeatedly for determining whether it should change its moving path. In addition, when the robot encounters obstacles with different properties, the robot can adapt to change its paths automatically based on the properties of the obstacles.
