Substrate Container Lifting Mechanism for Heavy Loads

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

As substrate diameters increase, substrate storing containers become significantly heavy, making them difficult to remove from packing boxes without a lifting device.

Innovation Solution

A packing structure with a lower lid and sleeve member configuration that includes device positioning portions for engaging a lifting device, allowing for precise and reliable positioning and lifting of the substrate storing container, even when the upper lid and sleeve member are removed.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If substrate diameter is increased, then substrate storage capacity is improved, but container weight increases significantly

Engineering Contradiction:

Improvesubstrate storage capacityVSAvoidcontainer weight

Core Design Contradiction:

Quantity of substanceVSWeight of moving object

Solution Approach 1:

The container is divided into a container main body and a lid body that can be separated. The lid body can be removed to allow lifting devices to access and lift the container main body containing heavy substrates, solving the problem of handling heavy containers while maintaining substrate storage capacity.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

A lifting device is introduced as an intermediary tool to handle the heavy container main body. The lifting device engages with the container main body through lifting device engagement portions and lifts it using lifting force, enabling safe and easy removal of heavy containers without direct human handling.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of operation

If lifting device engagement portions are added to the container main body, then ease of lifting is improved, but device complexity increases

Engineering Contradiction:

Improveease of liftingVSAvoidcontainer structure complexity

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

Lifting device engagement portions are added only to specific locations on the container main body where lifting is needed, rather than modifying the entire container structure. This localized addition provides lifting functionality while minimizing overall structural complexity.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The lifting device engagement portions are integrated into the container main body structure, merging the lifting function with the container structure. This combination allows the container to serve both its storage function and its lifting function without requiring separate independent lifting mechanisms.

Inventive Principle:

Principle #5Merging (Combining)

AI summary

The lower lid includes a bottom plate that supports the substrate storing container and a lower lid peripheral wall that extends upwards from a periphery of the bottom plate. The sleeve member has a tubular shape having an axial center that extends in the vertical direction. The upper lid has a top plate and an upper lid peripheral wall that extends downwards. The lower lid includes device positioning portions. The device positioning portions can engage the positioned portion of the lifting device that lifts, from the lower lid, the substrate storing container which is supported by the lower lid in a state of the upper lid being removed therefrom.
