Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the moving speed of the moving object is kept constant, then the operation is simple, but the arrival time at each manufacturing step cannot be adjusted to match the manufacturing status
Solution Approach 1:
The patent implements dynamic speed adjustment by transitioning from constant speed operation to variable speed control. The remote controller receives manufacturing status information and dynamically adjusts the moving object's speed to ensure timely arrival at each manufacturing step, resolving the contradiction between operational simplicity and manufacturing timing requirements.
Solution Approach 2:
The system establishes a feedback loop where the remote controller continuously receives manufacturing status information from the manufacturing system and adjusts the moving object's speed accordingly. This feedback mechanism enables the system to adapt speed based on actual manufacturing conditions, preventing delays while maintaining manageable operation through automated control.
2Productivity
If the moving speed is dynamically adjusted based on manufacturing status, then the arrival timing at each step is optimized, but the system complexity increases
Solution Approach 1:
The patent introduces a remote controller as an intermediary device that manages the complexity of dynamic speed adjustment. This intermediary receives manufacturing status information and translates it into appropriate speed commands, shielding the moving object's control system from complex manufacturing system details while enabling optimized arrival timing at each step.
Solution Approach 2:
The remote controller serves multiple functions: it acts as a communication interface, a decision-making unit, and a speed control device. By consolidating these functions in a single multi-functional component, the system achieves optimized manufacturing efficiency without proportionally increasing overall system complexity.
3Loss of time
If remote control is implemented to adjust speed, then the manufacturing timing is optimized, but the communication requirements and system integration complexity increase
Solution Approach 1:
The remote controller serves as a communication intermediary that simplifies the interaction between the manufacturing system and the moving object. It receives status information from manufacturing systems and sends control commands to the moving object, reducing direct communication complexity while enabling timely speed adjustments to optimize step transition timing.

AI summary
A system used in a factory for manufacture of a moving object comprises: a remote controller that moves the moving object by remote control, the moving object being movable in the factory during a course of manufacture in the factory, the moving object including a communication device having a communication function for the remote control and a driving controller that implements driving control over the moving object; a manufacturing status acquisition unit that acquires information about a manufacturing status in the factory including delay in a step; and a speed setting unit that sets a moving speed of the moving object using the acquired manufacturing status. The remote controller moves the moving object in a transport zone between steps at the set moving speed of the moving object by the remote control.
