Transporter Hold-Down Elements Prevent Container Swing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Linear transporters cause containers to swing or oscillate during cycled or incremental movement, leading to potential spills and contamination, as existing designs lack effective stabilization mechanisms.
Innovation Solution
The integration of hold-down and support elements on container holders and grooves provides additional contact surfaces for container flanges, preventing swinging and oscillation without requiring additional moving elements, ensuring containers remain stable during transport.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If containers are transported in a cycled or incremental manner while held suspended by a container flange, then the transport process can be continuous and efficient, but the containers tend to swing or oscillate which impairs process reliability and may cause spills
Solution Approach 1:
The container holder is segmented into multiple functional zones: a base portion for supporting the container flange, and additional hold-down elements that independently contact the container flange at different locations. This segmentation allows each element to perform a specific stabilization function, preventing swinging while maintaining continuous transport.
Solution Approach 2:
Hold-down elements are introduced as intermediary components between the container flange and the container holder body. These elements act as mediators that apply localized contact forces to prevent oscillation without interfering with the overall continuous transport mechanism. The hold-down elements translate the motion of the container holder into stabilizing forces on the container.
2Reliability
If additional elements are added to prevent container oscillation, then process reliability improves, but the device complexity increases
Solution Approach 1:
The hold-down elements are merged with the container holder body, forming an integrated structure. The hold-down elements and base portion together form the complete container holder assembly, eliminating the need for separate, independently actuated stabilization mechanisms. This merging reduces device complexity while maintaining reliability.
Solution Approach 2:
The container holder is designed with multi-functionality: the base portion supports the container flange while the hold-down elements simultaneously prevent oscillation. This universal design allows a single component (the container holder) to perform multiple functions—transport, support, and stabilization—without requiring additional dedicated elements for each function.
3Ease of manufacture
If the container holder design is simplified to reduce complexity, then ease of manufacture improves, but the ability to prevent container oscillation may be compromised
Solution Approach 1:
Instead of adding complex active stabilization mechanisms to prevent oscillation, the design inverts the approach by using the passive geometry of the container holder itself—the hold-down elements and base portion configuration—to inherently prevent swinging through proper structural design. This inversion simplifies manufacturing while maintaining stabilization capability.

AI summary
A container carrier that moves containers in a transport direction has container holder with a recess and a hold-down. The recess receives a container between its mouth and its flange and forms a bearing surface to support a lower face of the flange thereby suspending the container. Meanwhile, the hold-down engages the opposite or top face of the flange to prevent the container from swinging.
