Solution Overview

Problem

Traditional clean rooms are fixed in factory buildings, requiring high costs and long installation times during relocation due to disassembly and reassembly processes, which are cumbersome and do not meet the needs of rapid technological evolution.

Innovation Solution

A modular clean room system with self-locking devices and automatic switching mechanisms allows for rapid disassembly and relocation, featuring sealed connections between modules via self-locking devices and controllers for coordinated operation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If traditional fixed clean room is used, then structural stability is ensured, but relocation cost and installation time increase significantly

Engineering Contradiction:

Improverelocation capabilityVSAvoidinstallation time

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

The clean room is divided into multiple modular units that can be independently assembled and disassembled. Each module contains complete functional components (sealing windows, self-locking devices, sealing members), enabling rapid relocation without complex reinstallation while maintaining structural integrity during movement

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system incorporates automatic switching devices and self-locking mechanisms that dynamically adapt during assembly and disassembly operations. The automatic switching device controls sealing window opening/closing based on locking status, while self-locking devices automatically engage or disengage based on module connection state, significantly reducing manual operation time during relocation

Inventive Principle:

Principle #15Dynamics

2Adaptability or versatility

If traditional fixed clean room is used, then sealing stability is maintained, but relocation complexity increases

Engineering Contradiction:

Improverelocation capabilityVSAvoiddisassembly complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The self-locking device automatically locks when two modules are connected, and the automatic switching device automatically opens the sealing window based on the locking signal without requiring manual intervention. During disassembly, the system automatically releases locks and closes windows, making the complex operations occur autonomously and reducing operational complexity

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The self-locking device provides locking status feedback to the automatic switching device, which then controls the sealing window state accordingly. This feedback mechanism ensures coordinated operation of multiple components during assembly and disassembly, maintaining sealing stability while simplifying the overall process through automated control logic

Inventive Principle:

Principle #23Feedback

3Productivity

If modular design with self-locking devices is used, then relocation speed increases, but sealing reliability must be maintained

Engineering Contradiction:

Improverelocation speedVSAvoidsealing reliability

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The sealing window is pre-configured with automatic switching capability that is triggered by the self-locking device status. Before module connection, the sealing window is in a predetermined state (open or closed), and the automatic switching device ensures it transitions to the correct state automatically when locking occurs, maintaining sealing reliability without manual intervention

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The automatic switching device acts as an intermediary between the self-locking device and the sealing window. It receives locking status signals from the self-locking device and automatically adjusts the sealing window state, ensuring that sealing reliability is maintained during the rapid relocation process without direct mechanical connection between locking and sealing components

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

A clean room module, a clean room system, and a self-locking method of the clean room module are provided. The clean room module includes: a housing provided with a sealing window, around which is arranged a seal; an automatic switching device connected with the sealing window to control opening and closing of the sealing window; a self-locking device provided at the housing and located on the side of the sealing window, wherein the self-locking device can be connected to and locked with a self-locking device of another clean room module from outside. When the self-locking device is locked: the seal forms a sealed contact with a seal of another clean room module; the clean room module sends a locking signal to a controller; and the automatic switching device opens the sealing window responsive to a window opening signal generated by the controller according to the locking signal.
