Containment Work-Glove Access Control With Intervention Logging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing containment systems lack effective mechanisms to prevent unauthorized interventions by operators, particularly in work chambers where equipment for processing materials is present, and there is a need for comprehensive logging of actions performed at port flanges.
Innovation Solution
A work glove system with integrated shut-off parts and capture units that record personal data, using microcontrollers to authorize access and block or unlock access based on data correspondence, combined with safety sensors and RFID technology to ensure secure and logged interventions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a work glove is installed on a port flange to allow operator intervention in the work chamber, then ease of operation is improved, but security against unauthorized intervention deteriorates
Solution Approach 1:
A shut-off part is introduced as an intermediary component between the operator and the work chamber. This shut-off part can be moved between a blocking position (preventing access) and an open position (allowing access through the work glove). The shut-off part acts as a mediator that controls when intervention is permitted, thereby maintaining security while preserving operational capability when authorized.
2Reliability
If a shut-off part is added to block access to the work chamber, then security against unauthorized intervention is improved, but device complexity worsens
Solution Approach 1:
The shut-off part is merged with the port flange assembly, integrating the security function into the existing structure. The shut-off part shares the same mounting interface and spatial envelope as the port flange, combining multiple functions (access control, sealing, and structural support) into a single integrated component rather than adding a separate complex mechanism.
3Reliability
If a capture unit with microcontroller is integrated to authorize access, then security against unauthorized intervention is improved, but device complexity worsens
Solution Approach 1:
The capture unit with microcontroller is designed to perform multiple functions: capturing biometric data or codes, authorizing access, controlling the shut-off part position, and logging interventions. By consolidating these functions into a single multi-functional electronic unit, the system achieves high security without proportionally increasing complexity, as one component handles several critical tasks.
4Reliability
If safety sensors and logging are implemented to record interventions, then reliability is improved, but device complexity worsens
Solution Approach 1:
Safety sensors provide real-time feedback on the position of the shut-off part and the state of the work glove, which is fed back to the microcontroller. The microcontroller logs this information and can automatically respond to unauthorized attempts. This feedback mechanism enables continuous monitoring and automatic response without requiring complex manual surveillance systems.

AI summary
A work glove is installed at the port flange, with the result that the operator can enter the working chamber of the containment in a protected manner. A multiplicity of port flanges are usually mounted on the containment and a work glove is fastened in each case to the respective port flange. Machinery for processing material to be treated is often set up in the working chamber. In order to temporarily block the access, a shut-off part which can be moved into a blocking position and an open position is provided. In order to record personal data relating to the operator, the arrangement has a capture unit which has a connection to a microcontroller.
