Solution Overview

Problem

Existing loading systems require a large number of steps to properly position objects in containers, which can lower operating efficiency in manufacturing facilities.

Innovation Solution

A loading system with a container holder, adjusting mechanisms, a controller, a transfer mechanism, and position detectors that adjust the container's position based on detected information to align it with the loadable object during transfer, reducing the need for additional positioning operations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If centering operations are performed on objects temporarily placed in a container by interrupting support, then positioning accuracy is improved, but the number of operation steps increases and productivity decreases

Engineering Contradiction:
Improvepositioning accuracyVSAvoidoperating efficiency
Core Design Contradiction:
Manufacturing precisionVSProductivity

Solution Approach 1:

Instead of moving the object to center it within the container, the patent inverts the approach by moving the container itself to achieve centering. The container is displaced horizontally relative to the object during transfer, allowing the object to be positioned accurately without interrupting support or adding extra centering steps.

Inventive Principle:
Principle #13The other way round (Inversion)

Solution Approach 2:

The container position is adjusted preliminarily during the transfer process before the object is fully placed. The controller performs adjusting control to displace the container horizontally while the object is being transferred, ensuring proper positioning is achieved in advance before support transfer is completed.

Inventive Principle:
Principle #10Preliminary action

2Manufacturing precision

If multiple steps are used to place objects in proper positions, then positioning accuracy is improved, but device complexity and operation time increase

Engineering Contradiction:
Improvepositioning accuracyVSAvoidnumber of operation steps
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The patent merges the container positioning function with the object transfer operation. The adjusting mechanisms are integrated into the container holder, allowing position adjustment to be combined with the transfer mechanism operations. This eliminates the need for separate centering devices or additional positioning steps.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The container holder is designed with multi-functionality, serving both as a support structure and as a positioning device. The adjusting mechanisms enable the container holder to perform both holding and position adjustment functions, reducing the need for separate dedicated positioning equipment.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

A loading system includes one or more adjusting mechanisms configured to adjust a position of the container held by the container holder, a controller configured to control operation of the one or more adjusting mechanisms, a transfer mechanism configured to move a loadable object into a holding space of the container with the container held by the container holder to transfer the loadable object to the container, and one or more position detectors. The one or more position detectors are located to detect a relative position of a loadable object when the loadable object is held by the transfer mechanism and is in the holding space. The controller is configured to perform an adjusting control in which the position of the container is adjusted to place the container in a proper position with respect to the loadable object, the adjusting control being performed based on detected information from the one or more position detectors, and being performed during at least a portion of a process of transferring the loadable object by the transfer mechanism, and being completed before the loadable object becomes supported by the container.
