Securing Frame Assemblies with Inflatable Bags for Cargo Stabilization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional load stabilization methods for shipping goods in containers and truck bodies are inadequate, as they often result in damage due to shifting, tipping, and tumbling, and existing solutions like load bars, air bags, and site-built bracing are either ineffective, expensive, or labor-intensive.
Innovation Solution
The use of securing frame assemblies with rigid frame members and distensible bags that are inflated or filled with a pressurized fluid to securely engage and stabilize freight within shipping enclosures, allowing for easy reuse and consistent pressure control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional load stabilization practices are used, then shipping goods can be transported, but the goods are exposed to shifting, tipping and tumbling causing damage
Solution Approach 1:
The load stabilization system is divided into multiple independent frame assemblies, each capable of stabilizing specific portions of the cargo. Each frame assembly includes rigid frame members and separate distensible bags that can be independently adjusted and positioned along the length of the shipping enclosure, allowing segmented stabilization of different cargo sections.
Solution Approach 2:
The frame assemblies are pre-configured with rigid frame members and distensible bags before shipping. The bags are pre-attached to the frame structure with inflation valves, allowing for quick deployment and stabilization action before cargo shifting occurs during transport.
2Reliability
If load bars are used for stabilization, then cargo can be secured, but load bars are subject to theft and coming loose causing freight damage
Solution Approach 1:
The distensible bags are integrated with the rigid frame members to form a unified stabilization system. The bags are pre-attached to the frame structure with reinforcement elements, merging the flexible bag material with the rigid frame to create a composite stabilization device that eliminates separate components that could be stolen or loosen.
Solution Approach 2:
The rigid frame members act as intermediary structural elements between the distensible bags and the cargo. The frame members provide a stable anchor point for the bags, mediating the force transmission from the inflated bags to the cargo, preventing direct contact and potential loosening between bags and cargo.
3Object-affected harmful factors
If air bags are used for stabilization, then cargo can be cushioned, but air bags are expensive, difficult to use and subject to over inflation
Solution Approach 1:
The distensible bags include pressure-sensing elements that provide feedback on the inflation pressure. When the bags reach the optimal pressure for cargo stabilization, the system automatically stops inflation or releases excess pressure, preventing over-inflation and eliminating the need for manual pressure monitoring by the operator.
Solution Approach 2:
The frame assemblies are designed to be self-regulating during inflation. The rigid frame members provide structural boundaries that automatically limit the maximum expansion of the distensible bags, allowing the system to self-regulate pressure without external intervention or complex control mechanisms.
4Reliability
If site built bracing is used for stabilization, then cargo can be secured, but it is labor intensive and increases loading time
Solution Approach 1:
The frame assemblies are pre-assembled with rigid frame members and distensible bags attached before arrival at the shipping location. This preliminary configuration eliminates the need for time-consuming on-site construction of bracing structures, allowing for rapid deployment by simply inflating the pre-attached bags.
Solution Approach 2:
The stabilization system transitions from a static pre-assembled structure to a dynamic stabilized state through rapid inflation of the distensible bags. The rigid frame members provide immediate structural support upon inflation, dramatically reducing the time required to achieve effective cargo stabilization compared to traditional site-built bracing methods.
