Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional remote control interface with multiple buttons is used, then the robot can perform various operations, but the user must repeatedly press buttons at least ten times to complete simple reservation setting, increasing operation complexity and time consumption
Solution Approach 1:
The dial interface segments the control input into rotational movements that correspond to different command parameters. Each rotation of the dial represents a discrete input unit, allowing users to quickly navigate through options and input values without multiple button presses. The segmentation of rotational input into measurable angular increments enables efficient command entry.
Solution Approach 2:
The dial interface transforms static button pressing into dynamic rotational movement. The rotational angle, speed, and direction of the dial provide continuous variable input, allowing users to quickly adjust parameters by rotating the dial to the desired position rather than repeatedly pressing increment buttons. This dynamic interaction significantly reduces the time and number of operations required.
2Reliability
If a conventional remote control interface with multiple buttons is used, then the robot can perform various operations, but the user must repeatedly perform button pressing operations, increasing the possibility of input errors
Solution Approach 1:
The system provides visual feedback through light emitting units arranged in an inner circumference of the dial, which display user input information changed according to shuttling of the dial. This real-time feedback allows users to confirm their input intentions and correct mistakes before final submission, significantly reducing input errors while maintaining operational simplicity.
Solution Approach 2:
The patent replaces the mechanical button-pressing system with a rotational dial interface that uses angular position and velocity to encode command information. This substitution reduces the number of discrete input actions required and provides more precise control through continuous rotational movement, thereby improving input accuracy.
3Productivity
If a jog-dial interface is used to reduce input errors and enhance user accessibility, then command input becomes quicker and more efficient, but the interface must process and interpret shuttling rotation direction, angular speed, and angle information
Solution Approach 1:
The dial interface serves multiple functions: it detects rotational direction, measures rotation angle, and gauges rotation speed, all through a single unified input mechanism. This multi-functionality allows the system to extract multiple parameters from one interactive element, improving command input efficiency without requiring separate controls for each parameter.
Solution Approach 2:
The system interprets the dial's rotational parameters (angle, speed, direction) as varying input values that directly correspond to different command meanings. By mapping continuous physical parameters to discrete command categories, the system efficiently processes diverse control functions through a single interface element, balancing productivity gains with manageable processing complexity.

AI summary
A mobile robot system for allowing a user to easily input a control command of a mobile robot, and a remote control method for the same are disclosed. The mobile robot system and the remote control method thereof can allow a user to easily input control commands regarding the movement and operation of the mobile robot using the jog-dial interface, such that the possibility of causing input errors can be reduced and desired commands can be quickly and efficiently transmitted, resulting in increased user manipulation of the mobile robot system. When the user enters the rotation command of the mobile robot, the mobile robot system can allow the user to perform intuitive interfacing through shuttle manipulation, such that the mobile robot system can facilitate transmission of a movement command having a circular trajectory and the same mobile robot control as in the user-intended control is achieved, resulting in implementation of emotional interface capable of increasing user accessibility.
