Movable Wall Work Space Equipment for Clean Room Access Without Entry
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems require significant time and effort for preparing to enter and operate within managed pressure environments, such as clean rooms, due to the need for ancillary equipment and maintenance of cleanliness levels.
Innovation Solution
The implementation of work space forming equipment with a movable wall and definition sheet that allows for the creation of a work space separated from the managed environment, enabling easy access to work targets without entering the space, and includes a movable floor and control units to manage internal pressure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a worker enters the management space to perform operations, then direct access to the work target is achieved, but preparation time and effort increase due to cleanliness maintenance requirements
Solution Approach 1:
The system divides the management space into two distinct zones: a work space for operations and the managed management space. The movable wall creates this segmentation, allowing workers to perform tasks in the work space without entering the management space, thereby eliminating preparation requirements while maintaining direct access to work targets through the movable wall interface
Solution Approach 2:
The movable wall acts as an intermediary structure that provides a work interface between the worker and the work target in the management space. This intermediary allows operations to be performed on the work target without the worker physically entering the management space, thus avoiding cleanliness preparation while maintaining operational access
2Adaptability or versatility
If ancillary equipment is provided for operating the clean room, then operational capability is improved, but device complexity and cost increase
Solution Approach 1:
The movable wall serves multiple functions: it acts as a physical barrier maintaining space separation, provides a work interface for operations, and creates a functional work space. This multi-functionality eliminates the need for separate ancillary equipment while maintaining full operational capability, thereby reducing device complexity and cost
3Reliability
If the work space is separated from the management space, then cleanliness maintenance is improved, but access to the work target becomes more difficult
Solution Approach 1:
The movable wall provides dynamic adaptability, allowing the work space configuration to change based on operational needs. The wall can be positioned to provide direct access to the work target while maintaining separation from the management space, thus preserving both cleanliness reliability and operational ease through dynamic reconfiguration

AI summary
In the present invention, a work space equipment 3 comprises: a movable wall 33 that can enter a clean space 20 and exit from the clean space 20; and a defining sheet 34 that, while maintaining a state in which a work space 30 is isolated from the clean space 20, expands along with the entry of the movable wall 33 into the clean space 20 and contracts along with the exit of the movable wall 33 from the clean space 20. The work space equipment 3 switches to and from: an accommodation mode T1 in which the movable wall 33 exits from the clean space 20 to define a work space 30A; and an expansion mode T2 in which the movable wall 33 enters the clean space 20 to define a work space 30B that is larger than the work space 30A.
