Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If manually operated twist-locks are used to secure containers, then the locking function is reliable, but the operation complexity increases and remote control is not possible
Solution Approach 1:
The patent combines horizontal and vertical locking structures into a single integrated locking assembly that can be controlled by one actuator. This merging reduces the number of separate components and control mechanisms needed, enabling remote control while maintaining reliability.
Solution Approach 2:
The locking assembly is designed to perform multiple functions: horizontal locking, vertical locking, and self-locking, all through a single integrated mechanism. This multi-functionality eliminates the need for separate manual operations for each locking direction, achieving automation without proportionally increasing complexity.
2Volume of moving object
If traditional twist-locks with hand wheels are used, then the locking force is sufficient, but the space required for the mechanism increases
Solution Approach 1:
The patent replaces the manual hand wheel mechanism with a linear actuator system that uses more efficient mechanical advantage through cam surfaces and lever arms. This substitution reduces the space required for the actuating mechanism while maintaining or increasing the locking force through optimized force transmission paths.
Solution Approach 2:
The locking mechanism transitions from a primarily rotational hand wheel operation to a linear actuator movement that converts linear motion into rotational locking action through cam surfaces. This dimensional change allows for a more compact mechanism design that generates sufficient locking force in a smaller volume.
3Device complexity
If the actuator is used to hold the locking position, then the control is simplified, but the actuator load increases significantly
Solution Approach 1:
The locking assembly incorporates self-locking features where the horizontal and vertical locking structures automatically maintain the locked position through their mechanical geometry (cam surfaces and engagement features). This self-service mechanism eliminates the need for the actuator to continuously apply force to maintain locking, reducing actuator load while simplifying control.
Solution Approach 2:
The actuator performs preliminary action by moving the locking structures into their engaged positions, after which the self-locking mechanism takes over to maintain the position. The actuator only needs to overcome static friction to initiate movement, not to continuously hold the locking force, significantly reducing its load requirements.
4Object-affected harmful factors
If manual operation is required for locking, then the device structure remains simple, but the operator safety during loading and unloading is compromised
Solution Approach 1:
The patent replaces manual hand operation with an automated linear actuator system that can be controlled from a safe distance. This substitution eliminates the need for operators to be in close proximity to moving containers during locking and unloading operations, improving safety while maintaining straightforward control through the actuator system.

AI summary
A locking assembly (2) for securing a position of a load carrying object (4) with corner mounts (6) during loading, unloading or transport, the locking assembly (2) comprises a horizontal locking structure (8) movable between a first position, in which the horizontal locking structure (8) is arranged to protrude into a horizontal portion opening (10) of the corner mount (6) to restrict movement of the corner mount (6) in a horizontal direction, and a second position to release the corresponding horizontal movement restriction of the corner mount (6). The locking assembly also comprises a vertical locking structure (12) mechanically connected to the horizontal locking structure (8), the vertical locking structure (12) being movable between a third position, wherein a portion of the vertical locking structure (12) is arranged in an opening (14) of a vertical side of the corner mount (6) to restrict movement of the corner mount (6) in a vertical direction, and a fourth position to release the corresponding vertical movement restriction of the corner mount (6). The locking assembly (2) further comprises an actuator member (16) connected to one of the horizontal and vertical locking structures (8, 12), wherein the actuator member (16) is further structured to control the positions of both the horizontal locking structure (8) and the vertical locking structure (12) by a linear movement.
