Magnetic Holding Device for White Goods Release
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing holding devices for white goods on forklift trucks face challenges in efficiently releasing multiple items due to complex telescopic mechanisms and synchronization issues, leading to unsatisfactory performance when coordinating truck movement with release lever operation.
Innovation Solution
A holding device with a carrier part and movable holding units that use surface contact, such as magnetic elements or suction cups, and an actuator for controlled movement, allowing for efficient lifting and releasing of articles without requiring telescopic extensions, and adaptable to various implement carriers with quick-release fasteners.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a telescopic device is added to the carrier part to enable article release without pushing the article forwards, then the device can handle stacked articles and release them without forklift reversal, but the device complexity increases due to the telescopic fastening device and synchronization requirements
Solution Approach 1:
The invention extracts the telescopic function from a complex fastening device and implements it simply through the relative movement between the holding unit and carrier part. The holding unit moves backward on its mounting axis while the carrier part remains stationary, achieving the telescopic effect without requiring a dedicated telescopic fastening mechanism.
Solution Approach 2:
The invention segments the release function into two independent components: the holding unit that moves backward and the backstop that remains stationary. This segmentation eliminates the need for synchronized movement between multiple components, simplifying the overall device structure while maintaining the ability to release articles effectively.
2Device complexity
If the driver must reverse the forklift truck to release articles using the release lever, then no additional mechanical complexity is added, but the operational efficiency decreases and coordination difficulty increases
Solution Approach 1:
The holding device performs the release function autonomously through the actuator-driven backward movement of the holding unit. The system serves itself by internally managing the release mechanism without requiring external forklift movements, thereby improving productivity while maintaining acceptable mechanical complexity.
3Force
If magnets are used to grip the article for lifting and moving, then the holding force is sufficient, but the release mechanism requires additional complexity to overcome the magnetic forces
Solution Approach 1:
The invention extracts the release function from a complex mechanical override system and implements it through simple relative movement. By moving the holding unit backward on its mounting axis, the magnetic connection is naturally broken without requiring additional force application mechanisms, thus maintaining strong holding force while simplifying the release mechanism.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables efficient handling and release of multiple articles without telescopic extensions, improving operational simplicity and adaptability to different carrier sizes and types, ensuring secure and controlled lifting and moving of white goods.
Implementation Method 1
The holding part has magnets for gripping an article, typically a white goods item, which is to be lifted and/or moved
Implementation Method 2
the carrier part comprises at least one backstop against which the article can rest when the article is to be released from the at least one holding part; the at least one holding unit is movably mounted to the carrier part so that the at least one holding unit can be moved relative to the at least one backstop; the holding device further comprises at least one actuator for movement of the at least one holding unit relative to the at least one backstop
