Solution Overview
Problem
The inefficiency in manufacturing articles due to the need for multiple clean rooms to perform process simulation tests and product production concurrently, leading to increased contamination risks and inefficiencies in worker attire changes.
Innovation Solution
A facility with multiple work booths within a clean room, equipped with barrier sections at entrances and exits to prevent external airflow and contamination, allowing concurrent manufacturing and process simulation tests without compromising cleanliness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple clean rooms are used to concurrently perform process simulation tests and product production, then productivity is improved, but device complexity and contamination risk increase
Solution Approach 1:
The clean room is segmented into multiple isolated work booths, each capable of independently performing different tasks (process simulation tests or product production) simultaneously. The partition walls with independent air-lock systems create functional segments within a single clean room, allowing concurrent operations without cross-contamination.
Solution Approach 2:
Work booths are nested within the clean room structure, with each booth containing its own air-lock system and operational space. This nested configuration allows multiple independent work environments to exist within a single clean room boundary, enabling parallel operations while maintaining the overall cleanliness standard.
2Productivity
If multiple clean rooms are used to concurrently perform process simulation tests and product production, then productivity is improved, but the possibility of contamination increases
Solution Approach 1:
The clean room is segmented into multiple isolated work booths, each capable of independently performing different tasks (process simulation tests or product production) simultaneously. The partition walls with independent air-lock systems create functional segments within a single clean room, allowing concurrent operations without cross-contamination.
Solution Approach 2:
Air-lock systems serve as intermediary chambers between the clean room environment and the external area. These intermediate spaces allow personnel and materials to transition without directly exposing the clean room interior to potential contaminants, thereby preventing contamination while enabling concurrent operations.
3Object-affected harmful factors
If workers change clothes according to cleanliness levels when moving between clean room and outside areas, then cleanliness is maintained, but loss of time increases
Solution Approach 1:
Each work booth is equipped with its own independent air-lock system that workers can operate autonomously. The air-lock automatically manages the transition environment, allowing workers to maintain cleanliness protocols without requiring supervision or assistance from cleaning personnel, thereby reducing time loss while maintaining cleanliness standards.

AI summary
The present invention provides a facility capable of efficiently performing work while maintaining the cleanliness of a location where an article is manufactured, when manufacturing of the article and other work are performed in parallel concurrently; and an implementation method for manufacturing an article by using the facility. The facility comprises a clean room 1, multiple work booths 2 provided inside the clean room 1 and each comprising an entrance and exit, and barrier sections provided along entrances and exits of the multiple work booth 2 and configured to prevent airflow from the outside to the inside through the entrances and exits. The area inside each of the multiple work booths 2 has the same grade of cleanliness as the area that is outside the multiple work booths 2 but is inside the clean room 1.
