Solution Overview

Problem

Existing containers are inadequate for hoisting large electrolytic cells used in hydrogen production systems and offer limited space for maintenance, making it difficult to assemble and maintain the hydrogen production system efficiently.

Innovation Solution

A container design featuring a rotating side plate connected to a driving device, allowing the container to switch from a closed to an open state, facilitating the hoisting of large devices and improving maintenance access.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If a conventional container is used to transport the hydrogen production system, then the container structure is simple, but it cannot bear the weight of large electrolytic cells and requires separate transportation and on-site assembly

Engineering Contradiction:
Improvebearing capacityVSAvoidcontainer structure
Core Design Contradiction:
StrengthVSDevice complexity

Solution Approach 1:

The container adopts a movable side plate design that can rotate between horizontal and vertical positions. This dynamic structure allows the container to transition from a closed transport state to an open loading state, enabling the insertion of large electrolytic cells while maintaining structural integrity during transportation.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The container side plate is divided into movable segments that can rotate independently. This segmentation allows the side plate to be opened to accommodate large devices while maintaining the overall container structure, solving the contradiction between bearing capacity and structural simplicity.

Inventive Principle:
Principle #1Segmentation

2Ease of operation

If a conventional single-side opening container is used, then the container structure is simple, but it provides insufficient operating space and makes maintenance difficult

Engineering Contradiction:
Improvemaintenance accessibilityVSAvoidcontainer structure
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The side plate is designed as a movable component that can rotate between horizontal and vertical positions. During maintenance operations, the side plate can be rotated to vertical position to provide ample operating space for personnel and equipment, while returning to horizontal position for compact storage and transportation.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The side plate rotation mechanism adds a rotational dimension to the container structure, transforming it from a static single-opening design to a dynamic multi-position structure. This enables the container to provide different internal space configurations based on operational needs, significantly improving maintenance accessibility.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

AI summary

The present invention provides a container and a hydrogen production system. The container includes a bottom base, an upper cover, a first side plate, and a driving device. The first side plate is arranged between the bottom base and the upper cover, and is connected to the bottom base and the upper cover separately; and the driving device is connected to the first side plate and is configured to drive the first side plate to rotate relative to the bottom base, and the first side plate drives the upper cover to move, to switch the container from a closed state to an open state. The container in the present invention can implement hoisting of a device, so that a process in which the device is placed in the container is simplified, and the design efficiency of the hydrogen production system is improved. In addition, it is convenient for personnel to enter the container for device overhaul and maintenance, thereby effectively resolving the problem of inconvenient maintenance on the device after the device is placed in the container.
