Transport Unit Tension Devices for Cylindrical Cargo Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional transport units for cylindrical cargo objects are inefficient in utilizing transport volume due to unused spaces and struggle with securing cargo objects, especially when stacked vertically, as tension devices only engage partial circumferences, leading to instability and potential rolling.
Innovation Solution
Tension devices engage the faces of cargo objects, particularly at their edges, to create a stable and secure connection, allowing forces to be counteracted internally, and adapters with friction and form locks are used for coils, enabling effective horizontal force distribution and secure stacking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If cylindrical cargo objects are stacked horizontally in multiple layers on the transport base, then the transport volume utilization improves, but the stability of cargo objects deteriorates due to potential rolling and sliding
Solution Approach 1:
The cargo securing system is segmented into multiple independent tension devices, each responsible for securing specific cargo objects. Each tension device acts independently on its assigned cargo object, allowing stable stacking of multiple layers while maintaining individual cargo stability through dedicated securing mechanisms.
Solution Approach 2:
Wedges are inserted into the gaps between cargo objects before the tension devices are applied. This preliminary action creates a mechanical interlock that prevents rolling and sliding, establishing initial stability that allows the tension devices to effectively secure the cargo in horizontal stacking configurations.
2Stability of the object's composition
If tension devices are applied to secure cargo objects on the transport base, then the cargo stability improves, but the device complexity increases due to additional securing mechanisms
Solution Approach 1:
The tension devices are designed to be self-securing through a ratchet mechanism that automatically locks once tension is applied. The wedge elements also self-lock in the gaps between cargo objects through their geometric shape, eliminating the need for additional locking mechanisms and reducing overall system complexity while maintaining high stability.
3Stability of the object's composition
If cargo objects are stacked in triangular or trapeze shaped cross sections, then the cargo stability improves through interlocking layers, but the transport volume utilization deteriorates due to unused spaces at edges
Solution Approach 1:
The tension devices are designed with universal applicability to secure cargo objects in various stacking configurations including rectangular, triangular, and trapeze arrangements. The same basic tension device design can accommodate different layer patterns, allowing optimal volume utilization while maintaining stability through the universal securing mechanism rather than being constrained to triangular stacking.
4Volume of moving object
If the lowest layer includes three cargo objects disposed adjacent to one another, then the transport volume utilization improves, but the cargo stability deteriorates due to increased rolling risk at edges
Solution Approach 1:
The securing system applies local quality by positioning specific tension devices and wedges at critical locations such as edge cargo objects and layer transitions. This localized reinforcement provides enhanced stability precisely where rolling risk is highest, allowing the lowest layer to efficiently utilize transport volume with three adjacent cargo objects while preventing instability at vulnerable edge positions.
