Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing substrate storage containers face issues with transport components detaching due to impacts during transport or handling, necessitating improved mounting force to prevent detachment.
Innovation Solution
A substrate storage container design featuring a transport component with a protrusion system that engages with a main body protrusion, allowing for increased mounting force through controlled displacement and elastic deformation, restricting movement in multiple directions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If an elastic engagement piece is used to attach the transport component to the container body, then the attachment structure is simple and easy to manufacture, but the transport component may become detached due to impact during transport or handling
Solution Approach 1:
The attachment structure is divided into multiple engagement portions (first engaging portion and second engaging portion) that work together. The first engaging portion prevents detachment in the first direction, while the second engaging portion prevents detachment in the second direction, creating a multi-directional locking system that enhances reliability without complicating manufacturing
Solution Approach 2:
The first protrusion and second protrusion are designed with asymmetric geometries and different displacement characteristics under load. The first protrusion has a shape that allows greater displacement, while the second protrusion is designed to displace by a smaller amount under predetermined load, creating unequal engagement forces that prevent detachment from multiple directions
2Ease of operation
If the transport component is designed to be easily detachable for maintenance, then the ease of operation is improved, but the mounting force is reduced and detachment may occur during normal transport
Solution Approach 1:
The engagement structure incorporates controlled elastic deformation capabilities where the protrusions can displacement under load but return to their original positions. This dynamic behavior allows the attachment to maintain strong mounting force during normal operation while still permitting controlled detachment when needed for maintenance
Solution Approach 2:
The design utilizes changes in material properties and geometric parameters of the protrusions to achieve different displacement characteristics. The first protrusion is designed with parameters that allow greater displacement, while the second protrusion has parameters that limit displacement to a smaller amount, creating a balanced engagement system that provides both strength and operational flexibility
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 design enhances the mounting force of the transport component, preventing detachment during transport and handling, ensuring secure attachment even under impact conditions.
Implementation Method 1
the second protrusion is displaced in the second direction by a smaller amount than the first protrusion displaced in the second direction when the predetermined load is applied to the first protrusion toward the fourth side in the second direction

AI summary
According to one embodiment, a substrate storage container includes a transport component configured to be mountable to a container body by being relatively displaced with respect to the container body from the rear side to the front side. The container body has a container body-side protrusion protruding upward. The transport component has a transport component-side protrusion protruding downward. In a mounted state, the transport component-side protrusion is engaged with the front side of the container body-side protrusion to be restricted from being displaced backwards. When a predetermined load is applied to the transport component-side protrusion upwardly, the transport component-side protrusion is displaced by a smaller amount than the container body-side protrusion displaced when the predetermined load is applied to the container body-side protrusion downwardly.
