Bulk Liner Strap System for Bulge Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing container liners for bulk products face challenges such as bulging during filling, which obstructs container door closure, and require costly steel support bars or labor-intensive tensioning systems, necessitating a more efficient and cost-effective solution for bulk product transportation and discharge.
Innovation Solution
A liner system with strategically attached straps, including a first and second strap with overlapping diagonal sections, provides structural support to prevent bulging and facilitate easy installation, utilizing flexible materials like polyethylene or polypropylene to maximize containment and payload capacity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If steel support bars are used to prevent bulging, then the structural support is improved, but the cost increases significantly
Solution Approach 1:
The patent replaces expensive steel support bars with disposable plastic straps that can be easily installed and discarded. These straps provide sufficient structural support for single-use applications while dramatically reducing material costs and installation complexity.
Solution Approach 2:
The patent uses flexible plastic straps instead of rigid steel bars to provide structural support. The straps can conform to the container shape and provide adequate reinforcement against bulging while being much lighter and cheaper than steel.
2Strength
If a belt tensioning system is used to counter bulging, then the structural support is improved, but the installation time increases due to labor intensiveness
Solution Approach 1:
The patent divides the support system into multiple individual straps instead of using a complex continuous belt tensioning system. Each strap can be independently installed and tensioned, significantly reducing installation time and labor requirements while providing distributed structural support.
Solution Approach 2:
The straps are designed to be self-tensioning through simple attachment mechanisms that allow workers to install them without specialized equipment or extensive training. The straps automatically maintain tension through their structural design and attachment points.
3Strength
If multiple steel bars are used to oppose bulging, then the structural support is improved, but the device complexity increases
Solution Approach 1:
The patent replaces complex reusable steel bar systems with simple disposable plastic straps that are easier to handle, install, and dispose of. This simplification reduces device complexity while maintaining adequate support functionality for single-use container applications.
Solution Approach 2:
The patent uses flexible plastic straps instead of rigid steel bars, allowing the support system to adapt to container shape variations and simplifying installation. The flexible nature of the straps reduces the need for precise positioning and complex adjustment mechanisms.
