Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Robots may damage physical objects during release due to improper timing of impact application when releasing objects.
Innovation Solution
A robot system that includes a movement means to move a target object and an identification means to identify the timing of release based on physical quantities measured at the movement destination, such as force or acceleration, to mitigate impact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the robot releases the physical object at the movement destination, then the object can be delivered to the intended location, but impact damage may occur to the object
Solution Approach 1:
The system performs preliminary measurement of the object's physical quantity (weight, mass) before the release action. This preliminary action enables the control unit to calculate the optimal release timing in advance, allowing the robot to wait until the correct moment to release the object, thereby avoiding impact damage while maintaining delivery efficiency
Solution Approach 2:
The system continuously monitors the physical quantity of the object during transport and uses this feedback to determine the optimal release timing. The control unit adjusts the release moment based on real-time physical quantity measurements, ensuring the object is released at the precise moment when impact can be minimized, thus resolving the contradiction between efficient delivery and damage prevention
2Object-affected harmful factors
If the robot waits to identify the optimal release timing, then impact damage can be minimized, but the delivery time increases
Solution Approach 1:
The physical quantity measurement continues throughout the transport process without interruption. By maintaining continuous monitoring from the start of transport until the optimal release moment, the system eliminates the need for separate measurement phases, thereby minimizing time loss while ensuring accurate identification of the optimal release timing to prevent impact damage
3Object-affected harmful factors
If the robot uses force sense detection to control release timing, then impact can be reduced, but the system complexity increases
Solution Approach 1:
Instead of using complex force sense detection devices that directly measure impact forces, the system uses a simplified approach by measuring the object's physical quantity (weight/mass) which is a static property. This copying of the object's inherent property allows the control unit to calculate optimal release timing without requiring complex real-time force sensing hardware, thereby reducing system complexity while still achieving impact reduction
