Omnidirectional Load Transport for Faster Grid Direction Changes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing load handling systems in storage and retrieval operations face inefficiencies due to complex and time-consuming direction change mechanisms, which slow down the movement of transporting devices when changing directions.
Innovation Solution
The introduction of an omnidirectional driving unit allows the transporting device to move easily in multiple directions without the need to lift or lower wheels, using mechanisms such as ball-shaped rolling means, omniwheels, steerable wheels, air jet generators, or linear motors to drive and support the device on a grid-like structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional direction change mechanisms are used, then the transporting device can change direction, but the operational time increases and speed decreases
Solution Approach 1:
The patent replaces traditional mechanical direction change mechanisms (which require lifting and lowering wheels) with magnetic field-based propulsion. Electromagnets mounted on the transporting device interact with conductive rails to generate propulsive forces, eliminating the need for mechanical wheel adjustments and enabling instantaneous direction changes.
Solution Approach 2:
The patent employs magnetic field interactions between electromagnets and conductive rails to create propulsive forces. This electromagnetic propulsion system allows for rapid acceleration and direction changes without the mechanical complexity of traditional wheel-based systems.
2Ease of operation
If traditional direction change mechanisms are used, then the transporting device can change direction, but the speed of the transporting device decreases
Solution Approach 1:
The patent replaces traditional mechanical direction change mechanisms (which require lifting and lowering wheels) with magnetic field-based propulsion. Electromagnets mounted on the transporting device interact with conductive rails to generate propulsive forces, eliminating the need for mechanical wheel adjustments and enabling instantaneous direction changes.
Solution Approach 2:
The patent uses periodic activation of electromagnets along the conducting rails to propel the transporting device. By sequentially energizing electromagnets in a wave-like pattern, the system creates continuous propulsive force that maintains high speed while enabling rapid direction changes.
3Speed
If omnidirectional driving unit is used, then the speed of the transporting device increases, but the device complexity increases
Solution Approach 1:
The patent employs omnidirectional wheels that can function in multiple modes: they can roll forward/backward, rotate laterally for steering, and pivot for directional changes. This multi-functionality eliminates the need for separate mechanisms for each type of movement, reducing overall system complexity while enabling high-speed omnidirectional travel.
Solution Approach 2:
The patent uses dynamically adjustable wheel configurations that can change their orientation and function based on operational requirements. The wheels can transition between rolling, steaming, and pivoting modes, allowing the transporting device to adapt its movement characteristics in real-time without requiring multiple fixed mechanisms.
