Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Resin transportation containers deform under heat or heavy loads, leading to instability and inability to be reused, contributing to environmental waste.
Innovation Solution
A metal reinforcement fitting with hooking parts and a strip is attached to the bottom of resin containers, providing support and preventing deformation through upward biasing force, made from special steel with adjustable hardness and featuring a non-flat plate design for enhanced rigidity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the bottom of the transportation container is made thick or cross reinforcing ribs are provided, then the strength and rigidity of the bottom is increased, but the weight of the container increases and the complexity of manufacturing increases
Solution Approach 1:
The invention combines resin material for the container body with metal reinforcement fitting for strengthening. This composite approach allows the bottom to achieve high strength through the metal fitting without requiring the entire container to be made of heavy materials, thus improving strength while controlling weight.
Solution Approach 2:
The reinforcement is divided into separate components: the container body remains as resin while the reinforcement fitting is a separate metal component that can be attached as needed. This segmentation allows selective reinforcement only where required, avoiding unnecessary weight throughout the entire container.
2Strength
If the bottom of the transportation container is made thick or cross reinforcing ribs are provided, then the strength and rigidity of the bottom is increased, but the manufacturing complexity and cost increase
Solution Approach 1:
The reinforcement system is segmented into a separate attachable metal fitting rather than being integrated into the molding process. This allows the container body to be manufactured separately and simply, then the reinforcement fitting is added afterward, reducing overall manufacturing complexity.
Solution Approach 2:
Instead of making the entire bottom thick or adding complex rib structures throughout, the reinforcement is applied locally only at the bottom area requiring strength enhancement. This localized approach simplifies manufacturing by avoiding complex overall structural changes.
3Weight of moving object
If the transportation container is made of resin, then the container is lightweight and easy to manufacture, but the bottom bulges under heat or heavy weight and cannot be reused
Solution Approach 1:
The invention creates a composite structure combining resin container body with metal reinforcement fitting. The resin provides lightweight properties while the metal fitting provides heat resistance and structural stability under heavy loads, achieving both light weight and high reliability.
Solution Approach 2:
The metal reinforcement fitting is attached in advance to prevent bottom bulging before it occurs under heat or heavy weight conditions. This preliminary protective measure counteracts the deforming forces before they can cause permanent damage, enabling reuse.
4Weight of moving object
If the transportation container is made of resin, then the container is lightweight and easy to manufacture, but the container deforms under heat or heavy weight leading to instability
Solution Approach 1:
The resin container body provides lightweight properties while the attached metal reinforcement fitting provides structural stability. This composite construction maintains the weight advantage of resin while adding the stability of metal, preventing deformation under heat or heavy weight.
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
The metal reinforcement fitting stabilizes the container bottom, preventing bulging and extending the container's lifespan, allowing for reuse and reducing environmental impact by maintaining structural integrity under heavy loads and heat.
Implementation Method 1
the strip which is laid across laterally on the bottom, integrally formed with the pair of hooking parts, and connects the hooking parts to each other... the strip equipped with the hooking parts at both ends is attached to the bottom of the transportation container so that the bottom is reinforced

AI summary
A metal reinforcement fitting 10 including a strip 12 curved vertically upward is attached to a bottom 20b of a transportation container 20, and thus upward force can be applied to the bottom 20b. The upward force of the metal reinforcement fitting 10 can suppress downward force of a heavy article housed in the transportation container 20. Accordingly, if the metal reinforcement fitting 10 is attached to the bottom 20b of the transportation container 20 before the heavy article is housed, the bottom 20b can be prevented from bulging. Additionally, even if the bottom 20b of the transportation container 20 has already bulged, instability caused by deformation of the bottom 20b can be improved by attachment of the metal reinforcement fitting 10. Thus the provided metal reinforcement fitting has durability for long-term use of a transportation container.
