Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If manual setting of operation modes and control parameters is implemented, then flexibility and adaptability are improved, but setting time and operational complexity increase
Solution Approach 1:
The control device stores multiple operation modes (power-saving mode, soft operation mode, standard operation mode) with pre-configured control parameters in advance. During operation, the system automatically selects and applies the appropriate mode based on the conveyed object's characteristics, eliminating the need for manual parameter adjustment and reducing setup time while maintaining adaptability.
Solution Approach 2:
The system automatically determines the appropriate operation mode and control parameters based on input data about the conveyed object (weight, dimensions, fragility). The control device self-adjusts acceleration, speed, and other parameters without requiring operator intervention, thereby reducing setting time while maintaining full adaptability to different objects.
2Adaptability or versatility
If manual setting of control parameters is required, then operational flexibility is improved, but ease of operation deteriorates
Solution Approach 1:
The control device automatically selects and configures the appropriate operation mode and control parameters based on the conveyed object's characteristics. The system performs self-adjustment of acceleration, speed, and other parameters without requiring operator knowledge or manual intervention, making the system equally easy to operate for both experienced and inexperienced workers while maintaining full adaptability.
Solution Approach 2:
The control device acts as an intermediary between the operator's simple input (object characteristics) and the complex control parameter adjustments. It automatically translates basic input data into optimized control settings, eliminating the need for operators to directly manage complex parameters while preserving adaptability through automatic mode selection.
3Reliability
If conservative low-speed settings are used for safety, then reliability is improved, but productivity deteriorates
Solution Approach 1:
The system dynamically adjusts control parameters including acceleration, speed, and force based on the specific characteristics of the conveyed object. For fragile or heavy objects, conservative parameters ensure safety, while for robust objects, higher speeds and accelerations maximize productivity. This parameter optimization based on object characteristics resolves the contradiction between safety and productivity.
Solution Approach 2:
The control device implements dynamic parameter adjustment during operation based on real-time feedback and pre-stored operation modes. Rather than using fixed conservative settings, the system adapts parameters like acceleration and speed to match the specific requirements of each conveyed object, achieving both safety for vulnerable objects and high productivity for robust objects.

AI summary
A conveying apparatus that facilitates setting of an operation mode and setting of appropriate conditions during teaching is provided. An input determination section determines whether or not a combination of a conveyable weight and an operation mode input from an input portion is appropriate. A motor parameter determination section determines one or more motor parameters of at least one servoamplifier for one or more servomotors based on the operation mode and the conveyable weight determined as appropriate by the input determination section. The one or more motor parameters include a maximum speed and a maximum acceleration of the one or more servomotors. A parameter change section allows a speed and an acceleration of the one or more servomotors to be changed up to the maximum speed and the maximum acceleration, respectively.
