Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rack transporting devices require multiple components and complex operations to simultaneously drive racks on multiple transporting paths, which increases complexity and reduces efficiency.
Innovation Solution
A rack transporting device with a main transporting drive mechanism that simultaneously drives racks on two main paths and auxiliary transporting drive mechanisms with claw members to engage with receiving holes on the racks, allowing for coordinated transport between main and auxiliary paths using detectors for precise positioning and operation control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a motor is shared between two transporting paths to reduce component count, then the number of components is reduced, but operations to reconcile transporting drive on both paths become complex
Solution Approach 1:
The patent divides the transporting system into two independent drive mechanisms: a main transporting drive mechanism for the first and second main transporting paths, and an auxiliary transporting drive mechanism for the first auxiliary transporting path. This segmentation allows each drive mechanism to operate independently, simplifying control operations while maintaining a reduced component count compared to having separate motors for each path.
2Device complexity
If separate drive mechanisms are provided for each transporting path to simplify operations, then operational complexity is reduced, but the number of components increases
Solution Approach 1:
The patent merges the drive functions for the first and second main transporting paths into a single main transporting drive mechanism. This mechanism simultaneously drives both main paths, reducing the total number of motors while maintaining simple operations through coordinated control. The auxiliary transporting drive mechanism remains separate for the auxiliary path, providing the needed operational independence.
3Quantity of substance
If a single drive mechanism drives both main transporting paths simultaneously, then component count is reduced, but coordination and control between paths becomes difficult
Solution Approach 1:
The patent introduces detectors as intermediary devices that monitor the positions and states of racks on both main transporting paths. These detectors provide feedback to the control system, enabling automatic coordination and synchronization of the single main transporting drive mechanism across both paths, thereby simplifying control operations.
4Measurement precision
If multiple detectors are added to achieve precise positioning and control, then positioning precision is improved, but device complexity increases
Solution Approach 1:
The detectors in the patent serve multiple functions: they detect rack positions, monitor the presence of racks on transporting paths, and provide feedback for control decisions. This multi-functionality reduces the need for separate specialized sensors for each detection task, thereby improving positioning precision without proportionally increasing device complexity.

AI summary
A main drive mechanism provided with a main motor drives a rack on a first main path and a rack on a second main path simultaneously in the forward direction or simultaneously in the reverse direction. The rack is sent along a first auxiliary path by a first auxiliary drive mechanism. Then the rack is further sent in the forward direction along the second main path by the main drive mechanism. Once the rack leaves the first receiving region, the first claw member of the first auxiliary drive mechanism is sent to a retraction position and the rack is driven by the main drive mechanism in the reverse direction. The first claw member is then sent to an engagement position on the first main transportation path, the main drive mechanism is driven for transport in the forward direction, and the rack and the first claw member engage each other.
