Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the conveyance robot detects features of the load and changes the conveyance method, then the conveyance method can be adapted to the load characteristics, but the damage risk cannot be reduced before the conveyance method is changed
Solution Approach 1:
The system performs preliminary calculation of maximum allowable acceleration values in width and depth directions based on object kind and arrangement information before the conveyance robot starts moving. This preliminary determination of safe acceleration limits prevents damage from occurring before the conveyance begins, resolving the timing issue where damage prevention could not occur before method change.
Solution Approach 2:
The conveyance method is dynamically adjusted by calculating and applying different maximum allowable acceleration values for width and depth directions based on the specific object characteristics and arrangement. This dynamic adaptation allows the system to optimize the conveyance method for each specific load configuration while maintaining safety.
2Productivity
If the conveyance robot moves the box, then the objects can be transported efficiently, but the objects may be damaged due to excessive acceleration
Solution Approach 1:
The system changes the acceleration parameters by calculating specific maximum allowable acceleration values for width and depth directions based on object characteristics. These calculated parameter limits are applied during conveyance to prevent damage while allowing efficient movement within safe boundaries.
Solution Approach 2:
The maximum allowable acceleration parameters are calculated in advance before conveyance begins, based on object kind and arrangement. This preliminary parameter determination ensures that productivity can be optimized within pre-established safety limits, preventing damage before it occurs.
3Reliability
If the conveyance system calculates maximum allowable acceleration based on object kind and arrangement, then the damage risk is reduced, but the system complexity increases
Solution Approach 1:
The system performs preliminary calculation of maximum allowable acceleration values based on object kind and arrangement information before conveyance starts. This preliminary computation consolidates the complexity into an initial setup phase, allowing the actual conveyance operation to proceed with simpler real-time control based on pre-determined parameters.

AI summary
A conveyance system, a conveyance method, and a program reducing the possibility that an object that is accommodated in a box and is being conveyed is damaged are provided. A conveyance system conveys a box accommodating an object by conveyance robots. The conveyance system includes a first calculation unit configured to calculate, based on a kind and an arrangement of the object, a first maximum allowable acceleration indicating a maximum value of an allowable acceleration of the box in a width direction and a second maximum allowable acceleration indicating a maximum value of an allowable acceleration of the box in a depth direction.
