Swivel Front Handle With Automatic Locking Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing storage devices with handles lack effective mechanisms to prevent uncontrolled pivoting and accidental swinging of handles during transportation, leading to potential damage or discomfort in handling.
Innovation Solution
The storage device features pivotably mounted handles with integrated locking devices that automatically engage or disengage based on handle position, ensuring secure non-use positions and easy transition to use positions, preventing uncontrolled movement and enhancing handling comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the front handle is pivotably mounted on the container housing to enable flexible handling positions, then the ease of operation is improved, but the handle may uncontrollably pivot and swing during transportation, causing damage or discomfort
Solution Approach 1:
The handle is designed with dynamic characteristics, being pivotably mounted on the container housing to allow flexible positioning during operation. The pivotable mounting enables the handle to be adjusted to different angles and positions for comfortable gripping and maneuvering.
Solution Approach 2:
The locking device is integrated into the handle structure to prevent the harmful effect of uncontrolled pivoting before it can occur during transportation. The locking mechanism engages automatically or manually to secure the handle in a fixed position, counteracting the potential swinging and movement that would otherwise damage the handle or surrounding objects.
2Reliability
If a locking device is integrated into the pivotable handle, then the handle stability during transport is improved, but the device complexity increases
Solution Approach 1:
The locking device is merged with the pivotable handle structure, integrating the locking mechanism directly into the handle assembly. This combination allows the locking function to be achieved without adding separate, independent locking components, thereby reducing overall structural complexity while maintaining stability during transportation.
Solution Approach 2:
The locking device is designed to function automatically or through simple user interaction, where the handle's own movement or position triggers the locking action. This self-service approach eliminates the need for complex external locking mechanisms or additional actuators, keeping the device complexity low while ensuring reliable stabilization during transport.
3Ease of operation
If the upper handle is made pivotable to improve handling comfort, then the ease of operation is improved, but the handle may swing and collide with objects during transportation
Solution Approach 1:
The upper handle is pivotably mounted to provide dynamic positioning capabilities, allowing users to adjust the handle to comfortable angles for different carrying positions and operations. This pivotable design enhances handling comfort by adapting to various user preferences and operational requirements.
Solution Approach 2:
The locking device integrated into the upper handle prevents the harmful effect of uncontrolled swinging and collision with external objects during transportation. By securing the handle in a fixed position before transport begins, the locking mechanism eliminates the risk of the handle moving and damaging surrounding objects, thus preventing harm in advance.

AI summary
The invention relates to a storage device (1) comprising at least one storage container (2) which has an upper handle on an upper side (5) and a front handle (52) mounted on a front side (6) such that it can swivel about a swivel axis (51). The front handle (52) can be swivelled optionally into a non-use position (52a) swivelled towards the container housing (15) or into a use position (52b) swivelled away from the container housing (15). The front handle (52) is assigned a front blocking device (68), which is designed for unswivellably detachably blocking the front handle (52) in the non-use position (52a) thereof.
