Container Securing Device with Automatic Locking Stopper
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing container-securing devices fail to maintain secure stacking of containers during transportation, as movable protrusions can disengage upon impact, and require manual operation for locking, posing risks of damage and instability.
Innovation Solution
A container-securing device with a flange, support pillars, and a movable protrusion that is maintained in a locked state by a stopper, allowing automatic engagement and preventing disengagement even during rollover, and featuring a pivotable mechanism with elastic members for secure locking and unlocking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the movable protrusion is automatically engaged with the groove hole, then the locking operation is simplified, but the protrusion can move after container fixation causing untieing
Solution Approach 1:
The stopper is pre-positioned to engage with the movable protrusion and prevent its movement after automatic engagement with the groove hole. This preliminary constraint ensures that the protrusion remains locked in place even during container stacking operations, eliminating the untieing problem while maintaining automatic locking functionality.
Solution Approach 2:
The stopper acts as an intermediary element between the movable protrusion and the support pillar. It mediates the movement of the protrusion by providing a physical barrier that prevents the protrusion from disengaging from the groove hole, thus ensuring reliable container stacking without requiring manual intervention.
2Reliability
If the movable protrusion is manually operated for locking, then the locked state is maintained reliably, but the operation complexity increases
Solution Approach 1:
The device performs its own locking function through the automatic engagement of the movable protrusion with the groove hole, followed by the stopper automatically constraining the protrusion's movement. This self-service mechanism eliminates the need for manual operation while maintaining reliable locked state, reducing operational complexity without sacrificing security.
3Adaptability or versatility
If the movable protrusion is allowed to move freely, then the device adaptability is improved, but the container security is compromised
Solution Approach 1:
The stopper is pre-positioned to constrain the movable protrusion after engagement with the groove hole. This preliminary action maintains the adaptability of the device for different container configurations while simultaneously preventing the harmful effect of container untieing by ensuring the protrusion remains securely locked in place.
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
Ensures that containers remain securely stacked and attached to cargo beds during transportation, preventing untieing and coming off, even during rollovers, and allows for manual locking of the securing mechanism.
Implementation Method 1
a movable protrusion as part of the fitting portion for making a locked state when protruded laterally out of a vertical surface portion of the support pillar; a stopper for maintaining the locked state of the movable protrusion
